INTRODUCTION. 

Observations  op  the  Solar  Spots  during  Seven  Yeaes  and  a  half,  made  at  Redhill, 
ratOM  1853  to  1861,  by  R.  C.  Carrington,  Esq. 


The  observations  herein  contained  are  less  extensive  than  was  originally  intended,  still  it 
may  be  worth  while  to  give  a  short  account  of  Avhat  was  designed  to  be  done,  and  how 
the  design  has  been  modified  by  circumstances.  The  observatory  which  I  built  at  Redhill 
in  the  summer  and  autumn  of  1852  was  specially  arranged  and  fitted  for  meridian 
observations  of  Circumpolar  Stars,  as  stated  in  the  Preface  to  my  Catalogue  of  Stars 
published  in  1857.  AVhile  superintending  the  progress  of  the  buildings  and  kept  for  a  time 
from  access  to  instruments,  I  was  led  into  a  study  of  some  series  of  drawing's  of  the  Sun's 
disk  in  the  possession  of  the  Royal  Astronomical  Society,  and  following-  on  the  subject, 
as  one  of  great  physical  interest  and  of  increasing  importance,  was  much  impressed  with 
the  capricious  manner  in  which  observations  of  the  solar  phenomena  had  commonly  been 
taken  up  and  laid  aside  again,  the  entire  neglect  of  the  subject  by  the  public  establish- 
ments, grave  defects  in  the  methods  of  observation  commonly  employed,  and  as  might 
be  expected,  large  discrepancies  in  the  results  of  previous  observers  in  respect  of  the 
Elements  of  Position  of  the  Pole  and  Period  of  Rotation.  At  the  same  time  it  will  be 
remembered,  on  comparison  of  dates,  that  the  publication  of  the  Cosmos  of  Baron  v. 
Humboldt  bad  reached  that  part  in  which  he  collects  into  one  view  the  state  of  our 
knowledge  of  "The  Sun  considered  as  the  Central  Body/'  and  in  which,  for  the  first  time, 
due  prominence  was  accorded  by  one  of  those  minds  to  which  the  world  defers  to  the 
results  of  observation  of  the  Hofrath  Schwabe  of  Dessau.  It  was  at  the  same  time,  or 
nearly  thereabouts,  that  with  some  trouble  I  procured  a  copy  of  Professor  Rudolph 
Wolf's  "  Neue  Untersuchungen  liber  die  Periode  der  Sonnenflecken  und  ihre  Bedeutung-," 
in  which,  (though  priority  is  due  to  General  Sabine,)  the  parallel  is  pointed  out  between  the 
recent  periodic  variation  of  Solar  spot  frequency,  and  a  certain  periodicity  in  terrestrial 
magnetism,  and  a  first  endeavour  made  to  retrace  the  maxima  and  minima  of  past 
periods.  That  the  Solar  phenomena,  amid  the  universal  subjection  to  order  and  law, 
should  alone  be  subject  to  caprice  could  never  gravely  be  entertained  by  any  mind  of 
philosophic  training',  but  till  the  time  of  the  appearance  of  the  works  above  referred  to, 
the  attempts  of  several  able  men  had  tended  to  increase  a  very  general  conviction  that 
time  and  labour  would  be  thrown  away  on  such  a  subject,  and  that  beyond  the  limitation 
of  the  appearances  to  certain  zones  on  the  Sun,  there  was  nothing-  to  indicate  law  or  the

scale  of  time  on  which  changes  (if  any)  in  the  phenomena  took  place,  or  that  the  efforts 
of  a  lifetime  might  not  be  practically  wasted — and  have  as  their  sole  result  an  astrono- 
mical picture-book.  Hofrath  Schwabe's  labours  had,  however,  given  a  great  turn  to  this 
feeling,  and  the  time  had  plainly  arrived  for  the  Public  Observatories  or  some  of  them  to 
take  up  the  subject ;  yet,  calculating  on  the  slowness  with  which  action  in  these  matters 
commonly  follows  conviction,  I  thought  I  could  very  well  appropriate  the  Solar  Spots  to 
myself  at  Redhill  for  the  next  eleven  years'  period,  estimated  to  commence  in  1855  and  end 
in  I860,  and  that  a  close  and  methodical  record  of  the  phenomena  in  their  development  as 
a  whole  as  well  as  individually,  from  shortly  before  the  commencement  of  the  increase  of 
frequenc}',  till  a  sufficient  time  after  its  next  decrease,  would  probably  be  attended  with 
considerable  success,  and  at  least  ensure  for  the  subject  in  future  the  attention  of  the 
Public  Observatories.  I  therefore  decided  on  making  the  stud}'  of  the  Solar  Spots  my 
second  subject,  there  being  the  personal  advantage  that  while  the  observations  of  stars 
for  my  intended  Catalogue  required  the  hours  of  the  night  and  afforded  little  matter  for 
speculation,  the  observation  of  the  Sun  was  of  course  a  day-task,  and  presented  more 
variety  and  interest.  In  coming-  to  this  arrangement  it  is  proper  to  observe  that  I  did 
not  propose  to  myself  "  Solar  Pl^sics  "  in  their  entirety.  The  distribution  of  radiative 
power,  the  position  of  the  thermal  equator,  the  numerical  amount  of  illuminating-  power 
and  its  possible  variations,  the  estimation  even  of  the  degree  of  energy  exhibited  in  the 
production  of  spots,  and  many  other  features  were  consciously  left  aside,  and  the  subject 
before  my  mind  reduced  pretty  much  to  tracing  regularity  in  the  distribution  of 
the  maculae,  detecting  the  true  period  of  Rotation  of  the  Body  of  the  Sun,  and 
the  determination  of  the  systematic  movements  or  currents  of  the  surface,  if  such 
existed  in  any  definable  manner.  To  carry  out  this  plan  it  was  in  the  first  place 
necessary  to  devise  a  new  and  more  commodious  method  of  observation  than  any 
hitherto  adopted,  and  to  lay  altogether  new  foundations  of  method  in  recording-, 
reducing,  comparing-,  and  discussing-,  for  I  unhesitatingly  say  that  no  observer  would  for 
any  length  of  time  have  followed  out  any  of  the  modes  of  observation  previously 
practised.  If  he  had  dotted  down  the  spots  on  sheets  of  paper  on  which  he  had 
projected  an  image  of  the  Sun,  he  would  speedily  have  abandoned  his  subject  in 
disgust  with  the  inaccuracy  of  the  resulting-  positions  for  any  precise  object  of  research 
(that  is,  if  he  took  the  pains  to  discuss  them,  which  was  rarely  done),  and  if  he  had 
applied  the  micrometer,  he  would  speedily  have  found  that  half  his  opportunities 
of  obtaining  records  would  be  lost  while  making  his  necessary  preliminary  adjustments, 
and  that  he  could  very  rarely  instead  of  always  obtain  a  complete  record  of  a  single  disk. 
One  other  process  was  indeed  becoming  applicable,  namely,  that  of  photographic 
registration  as  recommended  by  Sir  John  Herschel  in  his  letter  of  April  1854,  which  has 
since  led  to  the  preparation  of  the  Kew  Photoheliograph,  but  I  did  not  see  my  way  to  its 
adoption  as  a  ready-made  working-  method  at  the  time,  and  was  not  disposed  to  lose  time 
in  experiments  in  which  I  should  be  interfering  with  the  ideas  and  speculations  of  others. 


INTRODUCTION.  6 

Perhaps,  I  may  add,  that  here  also  I  calculated  on  the  probable  slowness  with  which 
this  method  would  be  brought  actually  into  application,  feeling1  the  great  advantag-e 
which  I  then  possessed  as  an  unfettered  man  to  follow  out  my  own  devices,  and 
that  with  my  free  telescope,  I  should  probably  have  time  to  store  up  a  respectable 
harvest  before  the  new  reaping  machine  was  brought  to  perfection.  My  scheme  was 
perhaps  too  larg'e  for  a  private  person  to  entertain,  for  it  has  been  interrupted  half  way 
by  the  affairs  of  life,  and  I  have  to  console  myself  for  the  disappointment  of  a  partially 
spoiled  design  by  the  hope  that  the  method  I  have  planned  and  the  results  I  have 
obtained  by  it  may  shortly  lead  to  the  establishment  of  more  than  one  public  observatory, 
in  which  by  mutual  co-operation,  similarity  and  diversity  of  treatment,  this  special 
department  of  Astronomy  may  at  length  be  treated  as  its  importance  demands.  It  has 
not  been  without  the  successive  employment  of  several  assistants  that  I  have  been  able  to 
accumulate  and  present  the  results  of  the  observations  herein  contained.  During-  1854, 
1855,  1856,  and  1857,  I  took  all  the  observations  myself,  but  was  aided  in  their 
reduction  by  my  assistant  Mr.  Simmonds.  During  1858,  I  had  no  assistant,  and  my 
arrangements  were  greatly  disturbed  by  the  sudden  death  of  my  father,  the 
superintendence  and  ultimate  taking  up  of  whose  affairs  caused  much  absence  from 
Eedhill.  In  1859,  I  had  the  assistance  for  two  short  intervals,  of  Mr.  J.  Breen  and 
Mr.  H.  Criswick,  and  towards  the  close  of  the  year  engaged  Dr.  von  Bose,  who  shortly 
made  himself  familiar  with  my  methods  of  observation  and  reduction,  and  applied  them 
with  much  success  through  the  year  1800,  when  the  spots  were  very  numerous  and 
complicated.  On  his  departure,  I  engaged  Dr.  Schroeder  then  in  Paris  on  leave  of 
absence  by  the  department  of  public  education  of  Hanover,  and  who  observed  with 
tolerable  success  for  about  three  months.  On  his  departure  in  March  1801,  which 
occurred  sooner  than  expected,  in  consequence  of  his  being  recalled  to  become  Director  of 
a  provincial  school,  I  decided  to  close  the  series  and  wind  up  the  results  I  had  obtained ; 
the  necessity  of  my  being  personally  engaged  in  commerce  still  continuing,  and 
the  prospect  of  my  being  able  to  give  an  observer's  attention  to  the  subject  having 
become  very  remote,  in  consequence  of  a  decision  respecting  a  certain  appointment  to 
which  I  shall  not  more  particularly  allude.  I  have  had  much  assistance  in  preparing  the 
drawings  and  completing  the  numerical  reductions  from  the  same  Messrs.  Simmonds  and 
von  Bose,  the  latter  of  whom  has  since  become  my  assistant  again  in  another  capacity. 

I  have  in  a  former  paragraph  spoken  of  grave  defects  in  the  methods  of  observation. 
It  will  not  be  without  future  utility  if  I  name  a  few  by  way  of  public  execution,  for 
scientific  as  well  as  social  progress  is  sometimes  promoted  by  putting  the  laws  in  force. 
Such  are  in  my  opinion  the  following  : 

1.  Records  consisting  of  drawings  unaccompanied  by  determinations  of  positions  or 
even  of  scale. 

2.  Measures  of  positions  of  nuclei  belonging  to  groups  of  which  no  drawings  are  given. 
A  defect  much  more  pardonable  as  arising  from  the  great  demands  and  cost  of 

b2

illustrations,  but  which  is  destructive  of  their  value  when  used  as  data  for  founding- 
elements  upon. 

3.  Partiality  in  observations.  The  selection  of  large  or  special  objects  from  motives  of 
fanc}r  and  not  fair  samples  of  the  whole  disk. 

4.  Observations  of  differences  from  one  limb  only,  requiring  the  assumption  of  the 
diameter,  a  method  which  the  experienced  will  unite  in  condemning  as  needlessly 
faulty,  while  the  inexperienced  will  protest  he  sees  no  objection  to  it. 

5.  Measurements  so  made  (I  instance  Pastorf's,  though  with  all  respect  for  himself) 
that  their  reduction  for  any  purpose  whatever  would  be  attended  with  vastly 
more  trouble  and  less  profit  than  commencing  anew. 

6.  The  attempt  to  determine  the  direction  of  the  meridian  crossing  the  disk  b}'  running 
the  image  with  telescope  fixed  after  setting  down  the  positions  either  on  a  previously 
drawn  circle  or  obtaining  a  photograph.  I  fear  the  noxious  influence  of  this  notion 
more  than  an}r  other,  for  while  other  faults  are  readily  seen  and  put  aside  this  has  a 
semblance  of  accuracy  and  may  still  come  to  destroy  the  value  of  many  a  future 
record.  It  is  not  so  easy  to  procure  a  "  conviction  "  in  this  case,  for  condemnation 
will  onl}T  be  agreed  on  by  those  who  have  gone  through  much  labour  of  reduction 
with  disappointment  in  the  result.  I  have  known  several  persons  who  have 
accumulated  observations  untested  by  reduction  continue  to  practise  this  process, 
when  a  few  hours  spent  in  discussing  their  record  would  convince  them  of  the 
necessity  of  changing-  their  method  of  observation. 

I  pass  over  many  more  obvious  defects  depriving  records  of  all  scientific  value,  such  as 
drawings  by  mere  estimation  on  a  scale  of  less  than  two  inches  to  the  diameter,  although 
they  are  frequently  forced  upon  our  notice. 

In  the  next  place  I  will  briefly  refer  to  the  discrepancies  I  have  alluded  to  in  the  same 
paragraph.  I  found  matters  were  little  mended  since  1776,  in  which  M.  Lalande  in  his 
first  memoir  gave  a  table  of  u  Authors  who  have  determined  the  position  of  the  Solar 
Equator"  and  their  results.  These  results,  though  many  are  respectable,  might  be 
considered  as  superseded  by  the  more  modern  determinations  of  Laugier,  Bohm,  Petersen, 
Kysreus,  Bianchi,  and  others ;  but  still  the  results  stood  thus  :

I  may  perhaps  pass  over  some  other  determinations,  but  the  above  are  sufficient 
to  show  the  state  of  the  subject.  It  is  desirable  in  passing  them  in  review  that  notice  be 
taken  of  the  very  undue  prominence  of  supposed  value  given  to  the  Elements  of  Petersen 
(which  are  quoted  from  Astron.  Nachrichten,  No.  418,  Vol.  18,  p.  158)  and  which  are 


INTRODUCTION.  O 

based  on  the  eight  observations  of  one  spot  denoted  in  his  paper  by  the  letter  b.  It  is 
only  to  be  explained  by  the  circumstance  that  in  this  case  the  details  and  theory  were 
simultaneously  published,  and  that  the  observations  and  treatment  were  conducted  by  one 
in  whose  ability  confidence  was  placed.  If  the  spots  were  absolutely  fixed  points  on  the 
Sun,  the  single  series  discussed  as  it  was  would  have  given  an  undoubtedly  good  result 
for  a  single  series,  but  it  implied  a  total  forge tfulness  of  their  variability  of  form  and 
motion  for  this  result  to  have  been  so  often  in  after  years  quoted  with  evidently  high 
importance  attached  to  it.  The  result  of  Kysaus  is  quoted  from  his  Essay,  "  Ueber  die 
Axendrehung  der  Sonne  von  Rudolf  Kysaus,  Siegen,  1840,"  in  which  numerous  but 
not  convenient  formulae  will  be  found,  and  in  which  three  of  Petersen's  observations 
(including  his  spot  b)  are  taken  for  data.  The  result  is  therefore  of  more  weight  than 
Petersen's  own,  although  it  happens  to  be  in  each  element  further  from  the  truth.  Dr. 
Buhm's  Memoir  is  elaborate  and  the  details  of  his  observations  and  processes  are  given. 
I  find  no  particular  fault  with  it,  but  at  the  same  time  I  attach  no  particular  weight  to 
the  results.  M.  Laugier's  unpublished  Memoir,  so  far  as  I  could  judge  from  the  report 
on  it  by  the  referees  given  in  the  Comptes  Rendus  of  184:2,  was  of  much  higher  value, 
and  I  still  hold  it  to  be  a  matter  of  much  regret  that  he  should  have  delayed  the  publica- 
tion in  the  hope  of  improving  his  results,  till  the  probability  has  become  very  small  after 
the  lapse  of  twenty  years  that  the  public  will  ever  be  further  benefited  by  it.  To  M. 
Laugier's  results  I  attached  by  far  my  principal  confidence  on  account  of  the  number  of 
series  on  which  they  are  based  and  the  known  skill  of  the  Astronomer.  I  did  not  adopt 
lii>  results  absolutely  as  my  provisional  elements,  but  although  I  forget  at  this  time  the 
exact  reasons  by  which  I  was  led  to  use  slightly  different  elements,  it  is  now  curious 
to  see  that  I  even  thru  guessed  rightly  the  directions  in  which  they  required  correction, 
for  I  was  led  to  slightly  increase  his  value  of  the  Inclination  and  diminish  his  longitude 
of  the  Node.  While  the  position  of  the  Solar  Equator  was  thus  still  affected  with  an 
unknown  amount  of  error,  the  very  ideas  respecting  the  Period  of  Rotation  were  at 
fault.  I  shall  here  give  in  illustration  a  passage  from  the  letter  of  Bianchi  to  Schumacher, 
of  May  27,  1843.     (See  Astron.  Nachr.  483) : 

"  If  I  may  be  allowed,  I  will,  before  closing  my  letter,  put  in  a  little  claim  I  have  to 
priority  on  a  third  subject.  A  short  time  since  I  read  in  the  journals  the  Notice  of  the 
Report  made  to  the  .Academy  of  Sciences  of  Paris,  by  M.  Arago,  on  a  work  of  M. 
Laugier,  the  object  of  which  is  to  fix  with  certainty  the  period  of  Solar  Rotation  by  means 
of  observations  of  the  Spots.  The  learned  Secretary  and  Reporter  concluded,  and  I 
think  very  justly,  that  the  calculations  and  results  of  M.  Laugier  were  the  best  hitherto 
obtained  in  this  branch  of  research.  And  without  doubt  it  must  be  interesting  to  see 
how,  in  the  original  memoir  of  this  young  Astronomer,  he  lias  ascertained  and  established 
the  existence  of  proper  motions  among  the  spots  he  observed.  Nevertheless,  I  have  to 
remark  that  in  the  year  1817  I  observed  at  Milan  a  Solar  Spot  of  long  duration,  from 
which,  by  the  means  of  a  number  of  values  which  presented  a  good  mutual  accordance, 


0  INTRODUCTION. 

1  obtained,  as  the  time  of  the  sidereal  or  absolute  rotation  of  the  Sun  25*325  days,  a  result 
which  differs  very  slightly  from  that  of  Laugier.  My  paper,  containing  the  determination 
and  considerations  naturally  connected  therewith,  appeared  in  the  published  corres- 
pondence of  the  Baron  de  Zach  (see  Vol.  V.  pages  409—427,  and  pages  52.1—539). 
In  my  calculations  I  assumed  that  the  spot  had  no  movement  of  its  own,  which  was 
indicated  very  simply  by  the  invariable  size  and  figure  which  this  spot  presented  during 
three  or  four  successive  appearances.  Now,  if  M.  Laugier  and  I  thus  agree  in  the 
amount  of  the  Eotation  we  must  conclude  that  the  Solar  Spots  are  of  two  kinds,  those 
which  notably  change  their  place  on  the  Sun's  surface*  and  those  which  remain  con- 
stantly at  the  same  place." 

It  will  be  remarked  that  in  this  passage  from  the  writings  of  an  experienced  Astronomer, 
there  was  still  not  the  smallest  suspicion  that  the  differences  of  period  observed  were 
systematic,  or  that  they  depended  in  any  way  on  the  latitude  of  the  particular  spots,  or 
that  the  times  of  Rotation  of  the  general  body  of  the  Sun  and  of  its  fluid  surface  were 
different,  for  he  speaks  of  the  absolute  Rotation  of  the  Sun  as  determined  from  suitable 
observations  of  a  single  spot  as  a  possibility,  and  this  is  after  the  researches  of  Laugier 
on  the  subject.  It  will  be  seen  that  Petersen,  in  the  Memoir  I  have  referred  to,  contents 
himself  with  showing  that  his  five  spots  give  discordant  values,  and  Kysaus,  repeating  his 
reductions,  simply  remarks  that  the  mean  of  three  spots  gives  one  value  with  a  certain 
probable  error,  and  the  mean  of  two  of  them  a  certain  other  value.  Dr.  Bohm,  and 
in  short  all  others,  leave  the  subject  in  the  same  state.  Views  of  increasing  clearness 
are  however  expressed  in  an  admirable  little  paper  by  Dr.  C.  H.  F.  Peters,  now  of 
Clinton,  New  York,  published  in  an  early  Volume  of  the  Transactions  of  the  American 
Association  for  the  Advancement  of  Science,  entitled  "  Contributions  to  the  Atmosphero- 
logy  of  the  Sun,"  in  which  he  draws  his  materials  from  observations  of  some  extent  made 
by  himself  at  Naples  in  1845,  but  which  have  remained  unpublished,  probably  from  the 
difficulty  of  procuring-  admission  into  any  Transactions  of  the  necessary  number  of  illus- 
trations. I  quote  a  few  sentences  from  this  paper,  remarking  that  I  did  not  receive  it 
from  the  author  till  my  own  researches  had  made  considerable  progress. 

"  The  first  fact,  now,  which  offers  itself,  in  comparing  the  heliographic  places  of  one 
and  the  same  spot  for  different  days,  is  that  the  spots  are  not  invariably  attached  to  the 
Sun's  surface  but  have  proper  motion."  ....  "  Whenever  in  nature  a  motion  is 
observed,  inducement  is  given  to  research  of  laws  and  of  forces  causing  it."  .... 
"  A  general  proper  motion  of  the  spots  towards  the  Equator  (so  he  infers)  being  recognized, 
the  question  is  raised  naturally :  Have  they  any  motion  also  in  longitude  ?  and  in  what 
sense  (direction)  to  the  East  or  to  the  West  1  The  solution  of  this  question  is  intimately 
connected  with  the  determination  of  the  time  of  rotation.  For,  it  is  clear,  if  all  the  spots 
had  an  equal  proper  motion  in  longitude,  the  time  of  the  Sun's  rotation,  since  it  is  deduced

sufficient  theory.

from  the  spots  would  be  wrong-."  .  .  .  .  "  In  other  words,  it  is  the  time  of  rotation 
of  the  spots  which  results  and  not  that  of  the  Sun  itself."  .  .  .  .  "  By  means  of  this 
average  value  of  the  time  of  rotation,  now,  the  successive  places  leave  differences  so 
significant  that  there  can  be  no  doubt  of  a  very  considerable  motion  parallel  to  the 
equator.  The  displacements  in  longitude  seem  even  far  more  considerable  than  those  in 
latitude.  The  annexed  table  B  gives  some  examples.  Whether  there  be  a  common 
motion,  and  in  what  sense  (direction)  cannot  be  decided  in  the  present  state  of  our  know- 
ledge of  the  Sun's  rotation."     .... 

So  nearly  did  this  able  observer  come  to  the  term  in  latitude  without  obtaining  it,  and 
leave  its  actual  determination  to  me.  I  have  great  pleasure  in  referring  to  his  very  excel- 
lent remarks,  and  particularly  in  referring-  the  reader  to  his  description  of  the  normal 
history  of  the  process  of  development  and  reabsorption  of  a  spot,  in  which  his  indications 
are  much  in  advance  of  anything'  else  which  has  appeared  on  the  subject.  I  do  not 
intend  in  this  place  to  write  fully  on  the  previous  labours  of  others,  especially  when  the 
treatment  of  the  subject  has  been  directed  by  different  objects  in  view,  but  Dr.  Wilson  of 
Glasgow,  and  Sir  W.  Herschel,  are  two  observers  whose  conclusions  are  necessarily 
involved  directly  or  indirectly  in  every  research  subsequent  to  their  own.  I  allude  to 
Dr.  Wilson's  Memoir  in  order  to  remark  that,  although  I  hold  his  general  conclusion 
that  the  Solar  macular  are  cavernous,  or  hollows  in  the  general  level  of  the  luminous  sur- 
face, his  specific  description  and  diagram  conveys  an  impression  which  is  somewhat, 
erroneous.  Principally,  that  as  a  general  description  it  is  too  precise ;  there  is  more 
variety  in  the  appearances  than  he  confesses  to,  and  there  are  marked  departures  from  his 
description  of  form,  which  is  rather  one  specific  type  out  of  several  which  might  be 
adduced,  and  will  be  familiar  to  every  one  when  photography  has  furnished  us  with  forms 
on  which  all,  whether  observers  or  not,  may  rely.  Sir  W.  Herschel's  theory  of  the  section 
of  a  spot,  or  rather  Sir  John's  modification  and  improvement  upon  it,  requires,  in  my 
opinion,  reconsideration,  particularly  since  the  discovery  by  Mr.  Dawes  of  what  I  may 
momentarily  term  the  doubly  black  nucleus.  The  necessity  of  this  reconsideration  will 
be  felt  on  the  one  hand  when  due  attention  is  bestowed  on  its  capability  of  application 
throughout  their  duration  to  the  more  complicated,  as  well  as  to  normal  simple  spots ;  and 
on  the  other  hand,  when  the  motion  in  longitude  depending  on  the  latitude  as  now  estab- 
lished is  considered,  at  the  same  time  that  the  constant  relation  of  nucleus  and  penumbra 
is  remembered.  I  do  not  pretend  to  have  finally  formed  opinions  on  the  theory  of  the 
spot-section,  and  I  find  it  certainly  more  easy  to  frame  objections  in  this  matter  than  to 
remove  them  ;  but  I  think  a  certain  degree  of  attention  is  desirable  to  the  views  of 
Professor  Sestini,  as  published  in  the  Washington  Observations.  I  will  add  that 
Schwabe's  remark  must  in  any  case  be  borne  in  mind— that  the  depth  of  the  cavity  in 
some  instances  is  much  less  than  in  others,  and  is  certainly  variable.  Laugier  has 
remarked  (in  a  private  letter  to  me)  that  the  so  regarded  black  ground  of  the  nucleus 
frequently  appeared  to  him  under  high  powers,  when  the  atmosphere  admitted  of  their 
application,  as  an  assemblage  of  dark  points  with  little  interstices,  and  there  was  general

evidence  to  his  mind  of  a  sort  of  porosity,  he  even  says  resolvability,  using-  the  term  as 
applied  to  the  nebula?.  As  I  have  not  regarded  these  points  of  physical  interest  within 
the  scope  of  my  researches,  I  leave  them  at  this  point  to  succeeding-  observers  as  matters 
for  consideration.  It  suffices  for  my  present  purpose  that  a  simple  spot  is  a  cavity  of 
which  the  nucleus  may  be  regarded  as  the  shallow  bottom,  offering  a  tolerable  definite 
centre  as  a  point  of  observation. 

I  pass  on  to  the  conditions  I  proposed  to  comply  with  in  the  method  to  be  adopted  : — 

1 .  On  any  day  of  observation  every  spot  visible  and  observable  with  the  telescope  was 
to  be  observed  and  drawn,  without  preference  to  small  or  great. 

2.  The  observations  of  position  to  admit  of  great  rapidity,  in  order  to  be  a  match  to 
the  unfavourable  climate  in  which  thej  were  to  be  made,  and  therefore  the  necessity 
of  any  adjustment  of  the  telescope  to  be  evaded. 

3.  The  s}Tstem  to  be  such  as  admitted  of  brief  and  orderly  record,  in  a  form  obviously 
intelligible  at  any  future  time,  and  admitting  of  a  uniform  and  invariable  process  of 
reduction  with  as  few  figures  as  possible. 

4.  The  system  of  observation  at  the  same  time  to  be  of  a  high  degTee  of  accuracy, 
without  which  the  great  labour  necessarily  involved  would  not  be  adequately  com- 
pensated. 

5.  The  method  to  be  as  far  as  possible  applicable  with  any  ordinary  telescope  without 
special  appliances,  in  order  to  be  available  by  others. 

I  may  not  state  the  whole,  for  considerations  of  this  kind  are  of  the  nature  of  prophecy 
after  the  event,  and  do  not  occur  at  the  time  in  so  orderly  a  form.  One  method  is 
thought  of  and  tried,  and  found  to  have  objections  of  one  sort,  and  then  another,  and 
another,  till  the  observer  finds  he  is  satisfied,  and  cannot  further  improve  on  himself.  The 
method  I  have  pursued  did  not  occur  at  once  in  its  final  form,  but  grew  out  of  a  some- 
what rude  notion  of  making  the  disk  of  the  sun  its  own  circular  micrometer,  and  the 
process  of  reduction  was  successively  improved,  and  more  than  one  volume  commenced 
and  put  in  the  fire,  as  means  of  shortening  and  simplifying-  the  process  came  into 
view  by  practice  and  trial.  Firstly,  I  decided  on  observing  the  disk  by  projecting 
it  on  a  screen  placed  at  some  distance  from  the  eye-piece  of  the  telescope.  The 
telescope  used  was  my  Equatorial  by  Simms,  of  4-5  inches  aperture,  and  52  inches 
focal  length,  possessing  a  large  and  flat  field,  from  having  been  constructed  for  a  comet 
seeker,  and  armed  with  a  positive  eye-piece  of  power  25.  There  is  nothing-  new  so  far, 
the  very  arrangement  being  to  be  seen  in  the  earliest  work  of  the  Sun,  that  by  Scheiner, 
"  Rosa  Ursina  "  (p.  349),  in  which  the  idea  is  attributed  to  Gruenberger,  and  is  again 
found  to  be  emplo3'ed  by  Hevelius,  and  delineated  by  him  in  his  Selenography.  In  the 
focus  of  the  telescope,  however,  I  placed  two  bars  of  flattened  gold  wire,  at  right  angles 
to  each  other  (very  nearly),  and  turned  approximately  into  the  position  of  being  inclined 
45  degrees  on  each  side  of  a  meridian,  or  parallel  of  declination.      The  independence  of 


INTRODUCTION.  V 

the  result  of  the  bars  being-  exactly  placed,  is  the  feature  of  principal  importance,  as 
doing-  away  with  the  necessity  of  preliminary  adjustment,  and  the  telescope  being-  by 
this  means  always  ready  for  use,  without  the  loss  of  a  moment.  The  image  of  the 
Solar  disk,  and  the  cross  bars  in  focus,  was  projected  on  a  screen  provided  with  a 
support  to  hold  it  in  any  desired  position,  and  brought  out  with  distinctness  by 
placing  around  the  object-glass  a  large  collar,  to  throw  the  whole  apparatus  into 
shade.  The  screen  was  of  glass  roughened  and  then  coated  with  straw-coloured 
distemper  (or  colour  mixed  without  oil),  having  a  dull  surface,  trial  of  various  tints 
leading  to  the  adoption  of  a  pale  yellow,  and  glass  not  being  liable  to  curl  or  buckle  by 
the  action  of  heat  or  moisture.  The  image  was  first  made  to  be  from  12  to  14  inches 
diameter,  but  it  being  intended  to  record  the  appearances  to  a  scale  of  12  inches  in  the 
volume  of  reproduced  disks,  and  it  being  found  that  in  drawing  and  recopying  the  ten- 
dency was  always  to  draw  too  large,  the  image  was  shortly  reduced  to  11  inches,  to  allow 
for  unintentional  exaggeration.  The  telescope  was  held  firmly  in  declination  by  a  rod 
connecting  the  eve  end  and  the  lower  end  of  the  polar  axis.  In  Eight  ascension  an  ordi- 
nary good  clamp  maintained  it  in  position,  and  generally  immovably;  but  if  wind  caused 
any  vibration  it  was  sensibly  felt  in  Bight  ascension  only.  The  image  was  of  course  seen 
to  run  along-  the  screen  from  right  to  left,  the  true  north  limb  being  the  upper  limb  on  the 
screen,  and  contacts  were  in  all  cases  observed  at  the  eastern  edge  of  each  bar  only.  In 
Fig.  1  is  shown  the  general  arrangement  ;  in  Fig.  2  the  relative  positions  as  projected  on 
the  screen  ;  in  Fig.  3  the  disk  of  the  Sun  in  its  natural  position.  It  is  not  to  be  inferred 
from  the  equality  of  the  circles  in  Figs.  2  and  3,  that  the  field  of  view  was  equal  or  nearly 
equal  to  the  Sun's  disk:  its  diameter  was  about  four  times  that  of  the  Sun. 

The  observation  consisted  firstly  of  drawing  every  visible  spot  or  group  to  the  intended 
scale,  and  indicating  the  particular  nuclei  or  points  of  the  nuclei  selected  for  observation. 
To  these,  letters  of  the  alphabet  were  assigned  as  names  for  the  day,  and  then  the  order 
in  which  they  arrived  at  each  bar  written  down,  before  proceeding  to  note  the  time.  The 
disk  was  next  adjusted  by  moving  the  telescope  and  finally  clamping  it  in  declination,  so 
that  the  centre  should  pass  a  little  above  or  a  little  below  C,  the  intersection  of  the  bars ; 
the  position  of  some  spot  or  group  nearly  on  the  parallel  of  the  centre  commonly  being 
the  motive  of  the  selection  of  position-  there  being  no  theoretical  condition  to  comply  with 
beyond  that  the  centre  of  the  disk  should  be  within  a  moderate  distance  from  C.  The 
disk  was  then  screwed  back  by  turning  the  It.  A.  handle  of  the  instrument  to  such  a  posi- 
tion that  it  would  take  10  or  15  seconds  before  the  first  contact  of  either  limb  with  a  bar 
would  take  place,  and  then  the  handle  was  gently  released  and  a  second  taken  from  the 
Chronometer,  while  the  minute  vibration  of  the  telescope  in  11.  A.  was  ceasing  of  itself. 
The  times  of  contact  with  each  bar  were  then  observed  and  recorded  for  the  Sun's 
advancing  limb,  each  nucleus  selected  as  before  named,  and  Sun's  retreating  limb.  When 
the  number  of  spots  did  not  exceed  5  orG,  the  contacts  of  both  bars  could  commonly  be 
observed  with  ease  simultaneously,  and  in  these  cases  three  sets  of  passages  were  taken. 

c 


10  INTRODUCTION. 

But  when  an}T  difficulty  occurred  from  the  number  or  awkward  position  of  the  spots,  the 
contacts  of  the  two  bars  were  observed  separately  and  alternately  in  either  of  the  following 
orders,  three  of  one,  and  two  of  the  other : 

A,  B,  A,  B,  A,  or  B,  A,  B,  A,  B. 

When  both  bars  could  be  observed  at  the  same  time,  the  observation  would  take  about 
4  minutes  a  bar,  or  12  minutes,  besides  the  drawing-,  preparation  and  putting-  away ;  when 
separately  about  20  minutes,  as  there  was  a  trifling-  convenience  in  commencing'  a  set  at 
about  10  seconds  after  every  fourth  minute  for  the  comparison  of  the  numbers  afterwards 
and  detection  of  error.  It  is  a  feature  of  this  arrangement  of  considerable  value  in  point 
of  accuracy,  that  the  chromatic  separation  of  the  image  of  any  point  under  observation, 
whether  the  limb  or  a  spot,  is  of  necessity  in  the  direction  of  the  bar,  the  bars  being 
nearby  radial  from  the  centre  of  the  field  of  the  telescope,  and  consequently  that  the 
contacts,  which  take  place  at  right  angles  to  each  bar  respectiveh',  are  wholly  unaffected 
by  such  separation.  Let  Ax  A2  and  B,  B2  be  the  images  on  the  screen  (see  Fig.  2.)  of 
the  two  bars  placed  as  described,  SAB  the  path  of  any  point  within  the  Sun's  disk,  the 
N.  Polar  Dist.  of  the  centre  being  =  g.  Let  N  C  be  a  line  drawn  through  C  in  the 
direction  perpendicular  to  S  A  B  towards  the  North,  from  which,  if  the  Sun's  N.  P.  D. 
is  increasing,  it  will  differ  slightly  towards  the  West,  and  if  decreasing  slightly  towards 
the  East  by  a  quantity  (<),  which  can  afterwards  be  considered  as  a  correction.  Let  A 
and  B  be  the  acute  angles  S  A  Au  S  B  B1?  of  intersection  of  S  A  B  with  the  respective 
bars,  then, 

N  C  A2  =  90  —  A 

NCB,=  90  —  B  =  A  +  0 

if  the  North  Angle  of  intersection  of  the  bars,  or  A2  C  B,  exceed  a  right  angle  by  0. 
Next  let  F  be  the  factor  by  which  any  interval  of  time  shown  by  the  chronometer  requires 
to  be  multiplied,  to  convert  it  into  sidereal  time ;  then  if  the  point  observed  moves  from

Pass  next  to  Fig.  3,  in  which  lines  are  drawn  through  the  centre  of  the  disk  parallel  to 
the  bars,  and  in  which  S  is  the  supposed  position  of  a  spot,  and  suppose  the  times  of 
contact  to  be  designated  as  follows  : —

occasions  found  to  lie  between  2  and  5  minutes  of  arc.  The  general  effect  of  the  omission 
will  be  to  cause  the  deduced  heliographical  latitudes  of  all  spots  to  come  out  too  great 
by  a  small  quantity  which  can  never  exceed  £  0,  and  which  becomes  zero  at  the  middle  of 
the  spot's  passage  across  the  disk.  The  omission  in  any  case  can,  therefore,  have  had  no 
sensible  effect. 

With  the  calculated  distances  and  position-angles  of  the  points  observed,  and  the 
drawings  of  detail  of  each  group,  the  disk  as  observed  was  reproduced,  and  laid  down  for 
each  day  in  a  series  of  volumes  on  a  scale  of  12  inches  to  the  diameter  in  all  cases ;  and  in 
any  observatory  which  may  be  partially  devoted  to  this  subject,  it  will  be  desirable  that  a 
similar  pictorial  record  on  a  not  less  scale,  should  be  reproduced  and  preserved.  No  mere 
disks  are  included  in  the  present  plan  among  the  illustrations,  as  their  number  forbids  the 
contemplation  of  their  being  published.  An  equivalent  record  in  a  more  digested  and 
easily  comparable  arrangement  is  given  instead,  which  will  find  its  explanation  further  on. 

I  pass  to  the  second  stage  of  treatment,  by  which  from  relative  positions  on  the  disk 
are  deduced  the  heliographical  elements  of  each  spot. 

Let  (R)  be  the  sun's  semidiameter  in  minutes  of  arc,  and  let  p  =  ~  .  (R)     .     .     (see 

Fig.  4)  then  will  p,  the  angular  distance  at  the  Sun's  centre  of  S  from  C,  the  apparent 
centre  of  the  surface,  or  direction  of  the  earth,  be  given  by  the  relation 


since  in  the  fio-ure 


-^    =  sin  (p  +  p'),  or  p  ■■ 


-§4  =-£|   =  sin  0  S  *  =  sin  (S  0  E  +  S  E  0) 


In  Figure  5  let  P  be  the  position  of  the  Sun's  N.  Pole,  C  N  (as  before)  the  meridian 
through  the  apparent  centre,  S  the  spot,  N  DM  the  Solar  Equator,  N  the  ascending 
Node,  and 

N  D  M  =  L,  the  heliographical  longitude  of  C,  or  of  the  Earth  at  the  time. 

CM  =  D,  the  heliographical  latitude  of  C. 
N  C  P  =  &  +  H,  the  angle  G  being  the  inclination  of   two    planes  passing  through  the    line 
joining  the  centres  of  the  Sun  and  Earth,  and  the  poles  of  the  Earth  and  Ecliptic 
respectively,  and  the  angle  H  the  inclination  of  two  planes  passing  through  the  same 
line.,  and  the  poles  of  the  Sun-  and  the  Ecliptic  respectively. 
Also  let  /=  N  D  the  heliographical  longitude  of  S  reckoned  along  the  Solar  Equator  from  N. 

X  =  D  S  the  Spot's  heliographical  latitude. 
then  in  the  triangle  P  S  C  are  known 


therefore  readily

SC  =  P,  and  P  C  =  90-D

ecliptic,  N  M  the  Solar  Equator,  N  the  ascending-  Node,  C  the  direction  of  the  Earth, 
K  the  pole  of  the  Ecliptic,  P  the  Pole  of  the  Sun.     The  known  angles  and  sides  are 

M  N  C=I  ,  N  C  =  i8o°  +  0  —  N,  NMO  =  900 

tan  L  =  cos  I.  tan  (©  —  N) 
sin  D  =  sin  I.  (O  —  N) 
tan  H  =  tan  I.  cos  (0  —  N) 
similarly     tan  G  =  tan  w.  cos  O 

Tahles  of  these  quantities  for  every  degree  of  the  arguments  were  computed  with  the 
provisional  elements  1=7°.  10'  and  N=74°.  30'  for  1894-0,  copies  of  which  are  appended 
to  the  Preface ;  from  which  the  required  values  for  each  observation  were  found  almost  by 
interpolation  at  sight. 

I  proceed  to  give  a  complete  example  of  an  observation  and  the  process  of  reduction.

*  It  is  curious  to  perceive  in  Hie  first  memoir  of  Lalande,  that  while  intending  the  utmost  brevity, 
be  makes  two  steps  of  the  latter  part  of  the  process,  first  computing  the  eeliptical  longitude  and 
latitude  of  the  spot  before  passing  finally  to  the  heliographical.  It  will  be  noticed  also  that  ho

16  INTRODUCTION. 

as  they  will  there  be  found,  and  this  ends  the  reduction.  For  further  comparison  and 
discussion,  it  is  convenient  next  to  clear  the  heliographical  longitude  of  rotation,  at  least 
approximately,  and  for  this  purpose  a  near  mean  value  25a-380  was  provisionally  adopted 
from  its  admitting-  conveniently  of  much  subdivision  without  remainders.  In  Table  4 
are  given  the  epochs  of  the  coincidence  of  the  assumed  prime  meridian  with  the  ascending 
Node  of  the  Sun's  Equator  on  this  supposition  of  25-38  mean  solar  days  for  the  working 
period  of  rotation.  As  the  fractions  of  the  day  are  throughout  counted  in  civil  time 
from  the  preceding  midnight  1854 — 0d-00  here  signifies  mean  midnight  on  December 
31st,  1853.  In  Table  5  are  written,  1.  the  day  and  fraction  from  midnight  of  the 
observation ;  2.  the  difference  from  the  preceding  epoch  of  Table  4 ;  3.  this  difference 
converted  into  rotation-angle  in  the  proportion  of  300°  :  25d-38,  or  the  angle  through 
which  the  prime  meridian  had  rotated  since  its  last  coincidence  with  Node.  The 
deduction  of  this  amount  for  each  day  manifestly  leaves  us  a  heliographical  longitude, 
reckoned  in  all  cases  from  a  prime  meridian,  which,  if  our  period  be  correct,  is  constant, 
if  incorrect,  varies  slowly  with  the  time.  The  correctness  or  incorrectness  of  the  period 
in  any  small  degree  is  of  no  consequence  at  this  stage  of  calculation. 

I  regard  a  catalogue  of  positions  thus  obtained  as  of  little  use  without  the  correspond- 
ing fio-ures  of  the  spots,  at  the  same  time  that  it  is  impracticable  to  publish  the  disks 
singly  as  observed.  I  adopted  the  following  arrangement  which  I  hope  to  see  approved 
and  followed  in  future  records  of  the  Sun.  Two  features  require  to  be  illustrated,  1st. 
the  position  of  the  group  on  the  Sun  in  reference  to  the  Equator  and  to  the  assumed 
prime  meridian;  2nd.  the  changes  which  each  group  is  seen  to  undergo.  Accord- 
ingly,  I  formed  and  here  give  two  series  of  illustrations :  1st.  a  series  of  Rotations  as 
observed,  in  which  each  group  appears  once  for  all  in  its  observed  position  in  its  most 
typical  aspect,  and  in  which  the  meridians  passing  through  the  centre  of  the  disk  are 
indicated  for  every  day ;  and  2nd.  a  series  of  plates  in  which  each  group  observed  more 
than  once  is  fully  shown  by  arranging  the  recorded  figures  of  each  day  under  one  another 
in  succession,  from  the  top  to  the  bottom  of  the  page,  the  observation  of  the  day 
when  the  group  passed  the  centre  of  the  disk  occupying  the  middle  square.  This  series 
of  illustrations  shows  most  forcibty  the  devastation  of  the  record  by  the  badness  of  the 
climate,  it  being  a  rare  event  for  a  continuous  series  to  be  obtained.  The  particular  part 
of  the  nucleus  of  any  spot  which  was  observed,  may  always  be  found  by  comparison  of 
these  sheets  with  the  Catalogue,  and  thus  the  reader  is  put  in  possession  of  all  the 
information  of  the  observer  with  the  advantage  of  having  it  condensed  and  arranged  for 
further  inquiry. 

Between  the  first  and  second  of  these  series  of  diagrams  I  have  interposed  three  other 
sheets  s'iving  a  condensed  view  of  the  distribution  in  latitude,  which  though  shown  in  the 
series  of  Rotations  is  not  there  in  a  form  which  the  e}'e  can  catch  at  sight.  In  these 
plates  the  scale  is  materially  changed  by  giving  1  inch  vertical  for  10  degrees  of 
latitude,  and  ^  inch  horizontal  for  each  rotation   or  300  degrees   of  longitude.     The 


INTRODUCTION.  17 

immediate  result  of  this  examination,  which  was  published  some  years  since,  was  to  show  \ 
a  great  contraction  of  the  limiting-  parallels  between  which  spots  were  formed  for  two 
years  previously  to  the  minimum  of  1850,  and  soon  after  this  epoch  the  apparent 
commencement  of  two  fresh  belts  of  spots  in  high  latitudes  North  and  South,  which 
have  in  the  subsequent  years  shown  a  tendency  to  coalesce  and  ultimately  to  contract  as 
before  to  extinction.  Whether  this  is  what  occurs  at  each  period  of  increase  and 
decrease  of  frequency  of  the  Spots  must  be  left  to  observers  who  may  follow  me  to  show. 
At  present  it  is  only  probable  that  such  is  the  case,  and  another  contribution  made  to  the 
facts  on  the  broad  scale  which  will  ultimately  elucidate  the  origin  of  this  phenomenon 
and  instruct  us  on  the  question,  "  What  is  a  Sun  V 


Note. — On  the  corrections  required  for  Ellipticity  of  the  Solar  disk  and  for  Refraction. 

1.  In  fig.  7  let  C  D  be  drawn  parallel  to  the  minor  axis  of  the  elliptical  disk  and  C  D 
lying  between  C  N  and  C  A,,  let  the  angle  N  C  D=D,  then  D  C  B,=A+D  and  the 
angle  which  the  major  axis  makes  with  Bar  B=90° — (A+D). 

If  ])b  denote  the  perpendicular  from  the  centre  of  the  disk  on  bar  B  at  the  instant  of 
contact  with  bar  13,  and  a  and  b  are  respectively  the  major  and  minor  semiaxes,  and 
b2=a2  (1 — e2),  it  is  well  known  by  the  properties  of  the  ellipse  that 


pb  =  a.  (i  —  i-'-.  sin"  A  +  D)2 
and  ifpa  is  the  similar  perpendicular  on  bar  A  that 


p^  =  a.  (i  —  c-.  cos2  A  +  D)2 
and  in  this  case  Ave  must  substitute  for  our  previous  equations  the  following 
2  pb  =  15  sin  S.  F.  (B2  —  Bj)  sin  A 
1  pt  =  15  sin  8.  F.  (A2  —  A,)  sin  A

and  (G+H)  being  the  angle  before  described,  the  correction  for  this  assumed  ellipticity 

will  be 

A  —  A'=  +  103".  sin  2  (G  +  H) 

which  will  vary  from  +82"  to  —82"  since  2.  (G  +  H)  varies  from  +53°  to  -53°  (about). 


18  INTRODUCTION. 

The  correction  due  to  this  circumstance  is  therefore  negligible  in  daily  computation,  but 
may  just  affect  elements  of  the  Equator  as  it  has  a  yearly  period. 

3.  The  effect  of  Refraction  may  be  traced  with  sufficient  accuracy  by  following-  out 
the  general  consideration  that  all  distances  on  the  disk  parallel  to  the  vertical  will  be 
proportionally  shortened,  while  those  parallel  to  the  horizon  will  be  unaffected.  The 
angle  D  will  in  this  case  be  the  ang-le  at  the  centre  of  the  disk  between  the  great  circles 
drawn  to  the  Pole  and  the  Zenith,  +  S  for  E  hour  angles,  and  —  S  for  West.  The 
correction  will  be  of  two  kinds.  In  the  first  place,  the  angle  A  or  the  deduced  position 
of  the  bars  will  be  affected,  and  secondly,  the  position  angle  and  distance  from  centre  of 
each  spot. 

If  we  take  as  an  approximate  expression  for  the  refraction  at  any  Zenith  distance 

57"-5  .  tan  Z 
we  shall  have  as  the  relation  of  the  axes  of  the  disk 

b  =  a  (i  —  k)  where  k  =  57*5  sin  1".  sec  3  Z

and  each  spot  further  requires  the  correction

and

Ex.  In  spots  V  and  W,  August  9th,  1860,  take  0=  +  5'  (the  full  value),  and  the 
compression  as  above  assumed.

SECTION    III. 


Discussion  of  the  foregoing  observations  in  groups,  principally  for  the 
determination  of  the  diurnal  motion  in  longitude  and  latitude,  for  the 
after-determination   of  the  true  rotation  of  the  surface  of  the  sun  as 

INDICATED  BY  THE  MEAN  MOTIONS  OF  THE  SPOTS  IN  CONNECTION  WITH  THE 
PROVISIONAL   PERIOD   OF    ROTATION    ASSUMED    FOB    THE    PURPOSE   OF    REDUCTION. 


The  numbers  prefixed  to  each  paragraph  aro  those  of  the  groups  in  the  table  of  deduced  positions 
and  in  the  sheets  of  diagrams.  Where  a  group  returns  to  view  during  a  second  or  third  rotation, 
the  whole  of  the  observations  aro  commonly  discussed  together.  The  signs  prefixed  to  the  con- 
cluded diurnal  motions  aro  such  that  +  in  longitude  indicates  rotation  faster  than  140  n' per 
diem  (corresponding  to  the  assumed  period  of  25-380  days),  and   +    in  latitude  motion  towards 

either  Pole.     The  three  data  of  each  line  reprei rig  an  observation,  are — 1.  The  timo  expressed 

in  days  of  the  year  and  decimals  ;  2.  The  hrliogiMpIiical  longitude  cleared  of  rotation  at  the  rate 
of  140  11'  per  diem,  and  given  in  degrees  and  one  place  of  decimals ;  and,  3.  The  latitude  similarly 
given.  Notes  on  remarkable  divergence,  unusual  motions,  or  recurrence  in  the  same  region  are 
added  where  they  occur,  for  comparison  and  collection  afterwards.

22  and  2G.  Exhibiting  divergence  in  a  marked  degree.  The  first  line  of  data  is  formed 
from  the  mean  of  the  observations  on  the  12th,  13th,  and  14th,  the  second  from  those  of 
the  16th  and  18th.

Diurnal  motions  +  30'  and  4-6'      ....     for  lat.  —  70. 

The  motion  in  latitude  is  somewhat  uncertain  by  reason  of  change  of  figure  which  does  not 
equally  affect  the  result  for  the  longitude.  The  two  principal  nuclei  separate  by  about 
80'  per  diem,  more  rapidly  than  this  at  first,  and  afterwards  less. 

25  and  31.  No  trace  of  25  existed  on  March  6th,  and  the  two  dots  recorded  on  the 
9th  can  hardly  be  identified  with  any  distinct  part  of  the  fine  double  group  recorded  on 
the  11th.     I  deduce  for  the  principal  nuclei  of  25 

Mean  between.  Dist.

Divergence  considerable,  about  36'  per  diem,  even  when  the  distance  between  the  nuclei

24  and  29.  The  single  observation  of  24  indicates  that  two  nuclei  broke  out  on 
March  1st,  at  a  distance  apart  of  2£  degrees  in  the  mean  position  20#5  by  4-105. 
Omitting  the  observation  of  29  on  March  17th  as  too  near  the  limb,  we  next  find  these 
nuclei  in  a  mean  position  of  382  by  4-7*5  at  a  distance  apart  of  9  degrees  on  March  21st.

and  a  divergence  of  20'  per  diem  on  the  mean  of  20  days,  doubtless  more  at  first  and  less 
afterwards.  The  observations  of  the  circular  spot  29,  as  under,  are  of  no  use  as  data  for 
diurnal  motion,  the  spot  still  retaining  its  divergence  from  its  former  companion.

cate that  they  are  independent  groups.  The  changes  of  63  are  too  great  to  admit  of 
useful  comparison.  Indeed,  between  Sep.  12th  and  15th,  a  disappearance  and  fresh

in  this  instance  as  well  as  the  ordinary  divergence.

The  conclusion  is  of  little  weight,  the  observations  being  made  near  the  limb  on  consecutive 
days. 

167  and  171.  These  are  probably  different.  The  only  part  of  167  which  would  cor- 
respond in  longitude  to  171  the  next  rotation  was  vanishing-  when  last  previously  observed, 
and  the  latitudes  would  not  be  reconcilable.  The  unbroken  series  of  sketches  of  167 
shows  better  than  usual  what  might  be  obtained  in  a  finer  climate.  The  first  trace  and 
nearly  the  whole  history  of  the  group  are  recorded.  No  satisfactory  discussion  for  diurnal 
motions  is  however  possible.

174  and  184.  I  should  not  hesitate  to  identify  these  groups  as  the  same,  but  that  on 
Aug-.  31st,  174  was  manifestly  tending-  to  extinction,  and  on  Sept.  1st  and  2nd,  the 
Sun  ivas  observed  and  no  group  recorded  in  the  position  of  174.  184  came  on  on 
Sept.  20th,  as  174  was  last  seen  on  Aug.  31st,  having  two  simple  centres  at  the  same 
relative  positions,  and  affected  by  a  common  motion  in  longitude.  The  coincidence  is 
peculiar,  and  looks  like  evidence  of  the  revival  of  a  group  after  an  interval  of  several 
days.

recorded  as  dying-  away ;  and  on  the  next  day  an  outbreak  is  noted,  which  has  the

182  is  different  from  192  and  201,  inasmuch  as  on  Sept.  23d  it  was  no  longer 
visible.  This  spot  shows  fully  the  process  of  one  round  nuclear  spot  breaking  up  into 
two.     See  224  for  another  instance,  also  219  and  290.     I  treat  182  as  follows,

MR.   CARRINGTON's   OBSERVATIONS 


183  and  194.  Groups  204  and  211  are  distinct,  194  having-  disappeared  on  Oct. 
27th.  The  divergence  of  183  during  the  first  7  days  is  extraordinary,  and  the  instance 
is  favourable  for  noticing  that  the  separation  takes  place  in  the  line  joining  the  two 
spots,  and  is  not  merely  a  difference  of  motion  in  longitude.  One  spot  here  moves  North 
and  the  other  South  very  plainly.

The  position  of  the  mean  is  rendered  uncertain  by  the  degradation  of  one  of  the  component 
spots. 

195.  Very  near  the  Equator,  but  seen  only  on  two  days. 

197.  May  be  the  commencement  of  207,  but  uncertain. 

198.  Too  rapidly  chang-ed  for  comparison  of  parts. 

199.  The  principal  spot  subdivides  into  three,  which  on  November  1st,  1857,  appear 
in  contact.     The  interruption  of  the  record  by  weather  is  to  be  regretted.

was  more  than  30  degrees,  if  the  two  nuclei  seen  only  on  that  day  belong  to  the  same 
group  as  the  rest.

213,  214,  etc.  to  217.  Bad  weather  has  rendered  the  observations  too  inconsecutive

little  doubt  of  there  being  two  groups  with  the  remains  of  210  between  them  on  January 
9th.  The  portion  B  which  was  first  seen  on  that  day  admits  only  of  inspection.  The

*  On  referring  to  the  original,  I  find  that  the  ohservation  of  March  6th  is  not  reliable,  as 
snow  was  falling,  and  there  were  16  different  points  on  the  disk  to  be  observed.  Single 
contacts  only  were  procured. 

244  and  perhaps  253.  One  of  the  larg-est  groups  recorded.  Seen  generally  with  the 
naked  eye.  The  portion  of  244  in  longitude  290°  may  have  come  on  again  as  253,  but 
this  is  very  uncertain.  For  so  large  a  group,  the  duration  is  short.  Not  susceptible  of 
numerical  discussion.

240.  See  the  figures.  Comparing  those  of  March  21st  and  22nd  there  will  be  seen 
an  instance  of  one  spot  losing  its  penumbra,  and  of  another  having  penumbra  on  the 
22nd  which  had  none  on  the  21st.  The  nuclear  spot  recorded  on  the  2Gth  appears  to  be 
a  new  outbreak.     I  can  base  no  numerical  result  on  the  data  procured. 

247.  Perhaps  the  portion  which  was  situated  in  longitude  210°  might  be  treated 
separately  from  that  in  longitude  200°,  but  the  inferences  would  be  questionable.  259  of 
the  next  rotation  appears  to  be  distinct.

Both  results  must  be  taken  for  what  they  are  worth  with  others.     The  divergence  of  261  is 
remarkable.

only  0  small  dots.  The  quantity  of  penumbra  on  most  days  is  unusually  great.  The 
motion  in  longitude  is  evidently  positive,  but  the  observations  cannot  be  treated  in  any 
exact  manner.     291  may  be  the  remainder  of  this  group  next  rotation.

305.  The  record  exhibits  very  finely  the  first  day's  development  of  a  group.     I  take  it 
that  the  component   in  longitude  198  is  identical  with  318  of  the  next  rotation,  thereby 
showing  a  motion  in  longitude  changed  from   positive  (due  to  divergence)  to  negative 
(from  normal  causes).     The  observations  of  318  are  two  as  follows  :

penumbra  between  two  neighbouring1  nuclei,  which  formed  one  of  the  earliest  peculiarities 
noticed  by  Dr.  Wilson  of  Glasgow.     The  positions  observed  were

The  observation  of  this  very  splendid  group  on  September  Isl  has  had  some  notoriety.  Mr. 
Hodgson  at  Eighgate  and  I  al  Redhill  witnessed  and  described  a  singular  outbreak  <■!' 
tight  which  lasted  about  5  minutes,  and  moved  sensibly  over  the  contour  of  the  spot,  an 
account  of  which  lias  been  sufficiently  published  by  me  in  the  Monthly  Notices  of  the 
R.  A.  Society  for  November,  18 59,  and  since  reprinted  in  the  Philos.  Trans.  Vol.  151, 
Part  III,  by  Mr.  Stewart,  in  his  Memoir  on  the  Great  Magnetic  Disturbances  whicl 
extended  from  August  28th  to  Sept.  7th. 

Q22  and  511  are  probably  related,  but  there  being  but  one  observation  of  each,  com- 
parison would  be  too  precarious  to  be  introduced  here. 

525.  A  normal  spot  observed  twice  only.

584.  One  of  two  spots  disappears  and  the  other  shows  signs  of  divergence  from  it, 
precluding  results  for  motion. 

580  and  603.  Probably  the  same,  but  the  last  observation  of  580  and  the  first  of  003 
were  taken  when  the  spot  was  so  near  the  limb  that  comparison  with  the  only  other 
observation  obtained  would  yield  no  reliable  result.  See  513  for  great  similarity  in 
appearance. 

588.  See  608  and  030  :  the  last  probably  different. 

589.  The  figures  show  a  very  rapid  disappearance  of  the  larger  component  in  the 
course  of  two  days. 

594  and  010.  Only  one  observation  the  first  rotation.  When  come  round  the  second 
time,  much  diverged.  On  January  11th  the  diagram  indicates  a  second  outbreak  in  the 
place  of  the  first,  and  between  the  three  positions  of  the  remains  of  the  first  outbreak. 
Discussion  for  motion  seems  impracticable.

The  observations  of  the  spot  seen  in  the  position  68'4  by  —  30,  on  March  8th  and  15th,  are 
not  comparable,  inasmuch  as  no  such  spot  was  visible  on  the  10th  and  13th. 

6C0.  Either  different  dots  or  discordant  observations. 

661 — 665.  These  groups  admit  of  no  comment. 

666.  Two  separate  outbreaks  of  short  duration,  each  but  once  observed,  which  appear 
to  correspond  to  groups  689  and  691  of  the  next  rotation. 

607.  A  group  seen  twice  on  March  13  and  15.  Not  seen  on  the  18th.  In  the  next 
rotation,  690  occupies  the  same  position,  and  in  the  third  rotation  a  larg-e  group  (771) 
succeeds.  There  is  no  question  that  the  three  are  successive  independent  formations  or 
outbreaks  in  the  same  region.  This  and  other  cases  (666  immediately  before  is  another) 
indicate  that  the  source  of  energy  which  leads  to  the  formation  of  a  spot  or  group  is  not 
always  exhausted  on  the  disappearance  of  the  group  5  that  corresponding  to  the  visible 
spot  there  is  an  invisible  overhanging-  cloud  or  underlying  volcano,  the  discharge  of 
which  rupturing  or  displacing  the  photosphere  is  sometimes  intermittent.

See  drawings.     Note  also  the  general  direction 


Divergence  the  first  two  days  =  7  degrees 
of  the  group. 


707.  The  divergence  being  visible  on  the  face  of  the  drawings,  neither  spot  can  be 
treated  separately  ;  and  the  changes  of  the  principal  nucleus  prevent  their  being-  combined. 
It  will  be  noted  that  their  diverg-ence  is  sensible  when  these  two  spots  are  as  much  as 
15  deo-rees  apart.     The  principal  spot  subdivides  not  into  two  but  into  several  parts. 

708.  A  group  of  unusual  development  and  permanence  for  its  position  so  near  the 
Equator.  It  appears  to  me  that  the  whole  group  swings  round,  and  while  both  principal 
components  approach  the  Equator,  the  one  in  longitude  00°  to  65°  approaches  the  quicker.

The  positive  motion  in  longitude  seems  beyond  dispute. 

723.  I  point  out  one  feature  which  occurs  here,  and  which  has  occurred  frequently 
before  from  time  to  time,  the  bend  in  the  trajectory  of  successive  positions  near  the  limb 
to  the  left  at  the  top  of  the  pag-e  (coming-  on),  and  to  the  right  at  the  bottom  (going  off). 
See  groups  158,  161,  and  291 ;  and  58  and  139  for  the  opposite.  In  the  series  where  it 
appears  it  would  indicate  that  the  surface  of  the  photosphere  around  the  particular  spot 
was  sensibly  depressed,  as  a  little  consideration  Mill  readily  show.  It  does  not  always 
occur  and  is  not  necessarily  the  result  of  depression,  for  720  on  the  same  page  shows  the 
same  bend  when  well  advanced  on  the  Sun.  723  does  not  recur,  and  the  observations 
indicate  a  fresh  formation  on  May  27th.     Compare  these  three —

742.  Appears  to  have  been  three  small  separate  outbreaks,  of  which  nothing  more  can 
be  made. 

745.  Seems  to  be  properly  two  groups,  if  not  three.     None  are  susceptible  of  arith- 
metic discussion.     722  seems  a  precursor  of  part  of  this  group.

740.  Should  manifestly  be  entered  as  two  groups.  Notice  the  mutual  repulsion  be- 
tween the  "  following-"  component  of  the  "  preceding"  group,  and  the  "  preceding"  com- 
ponent of  the  "  following"  group.  Under  the  peculiar  circumstances  I  do  not  attempt  to 
deduce  motion.

of  the  same.     The  nucleus  in  longitude  45°  of  752  seems  to  recur  as  the  principal  spot  of 
776,  in  which  case  the  following-  positions  are  comparable.

753.  See  710  and  730.  The  motion  of  the  spot  in  lat.  —12°  has  been  discussed 
under  710.  The  spot  in  long-.  28°  and  lat.  —  16°  seems  to  be  a  fresh  outbreak  of  that 
part  of  710  and  may  even  be  repeated  in  777  in  long.  33°.     See  777. 


754  and  779.  This  enormous  group  has  large  negative  motion  in  longitude,  and  I 
think  that  the  principal  nucleus  of  754,  which  about  July  3rd  was  in  longitude  359  is 
comparable  with  779,  which  at  July  31st  is  in  347°:  but  the  changes  of  form  during  the 
first  rotation  are  so  great,  that  it  will  be  more  satisfactory  to  treat  779  by  itself  as 
follows :

It  is  possible  that  this  large  positive  motion  may  be  caused  by  divergence :  for  on  July  22nd 
the  drawing  shows  three  dots  close  together,  and  on  the  24th  one  is  first  traced  at  a 
distance  of  about  3  degrees.  The  motion  in  longitude  would  appear  to  be  exceptional  in 
any  case. 

772.  Two  dots  on  the  22nd,  which  the  position  of  one  on  the  24th  indicates  had  a 
mutual  action  on  one  another.     Accordingly  not  comparable. 

778.  See  749  and  796,  and  the  diagrams  given.  Such  groups  as  these  require  the 
application  of  photograph  v  in  a  climate  where  a  continuous  series  of  pictures  can  be 
obtained  with  certainty.  The  eye  and  hand  can  only  indicate  the  sort  of  changes  which 
might  be  so  registered. 

775.  See  751. 

776.  The  portion  in  lat.  +24°  is  treated  under  752.  The  portion  in  lat.  +20°  is  a  new 
addition  too  near  the  former,  and  too  little  observed  to  be  dwelt  upon  further.

781.  The  portion  in  +15°  had  apparently  begun  to  break  up  when  first  seen.  I  should 
have  expected  the  principal  nucleus  in  long.  328°  to  have  come  on  again,  but  it  does  not, 
and  therefore  I  do  not  work  out  its  apparent  motion.  The  following  spot,  normal  in 
form,  though  near,  seems  quite  independent  of  the  main  group.

783,  785  and  786,  are  sufficiently  Dear  to  one  another  to  throw  doubt  on  any  deduced 
motions.  783  might  be  supposed  to  correspond  to  807,  but  I  think  it  safer  to  take  that 
spot  by  itself.  The  great  group  785  returns  as  809  much  diminished,  but  during  its 
second  rotation  ag-ain  increases  to  be  a  ver}'  considerable  area  of  disturbance.  78(1  recurs 
as  813,  and  the  principal  nuclei  may  be  compared.  It  will  be  noticed  that  813  exhibits 
a  fresh  formation  in  the  course  of  its  progress.

810.  The  diagrams  indicate  a  variable  motion  in  longitude.  Numerical  treatment  is 
not  possible. 

811  and  834  must,  I  think,  be  the  same  spot.  During-  the  first  rotation  the  divergence 
is  large  and  the  motion  deceptive.  When  the  companion  has  fairly  disappeared  the 
normal  motion  is  shown.     A  curved  trajectory  is  the  result.

831.  A  dot  precedes,  the  influence  of  which  cannot  be  estimated,  and  the  observations 
are  otherwise  unfavourable. 

832.  This  spot  first  coalesces  from  a  double  form  and  then  fairly  divides  anew.  The 
motions  appear  small,  but  the  observations  do  not  admit  of  exact  statement.

835  and  853.  See  also  785  and  809.  The  form  of  809  in  the  second  rotation  was 
very  irregular.  I  therefore  estimate  the  following-  general  position  on  Sept.  4th  from  the 
diagrams.

The  last  or  supposed  fifth  rotation  most  probably  belongs  to  the  same  spot,  but  not  strictly 
to  the  same  nucleus.     The  second,  third  and  fourth  rotations  concur  in  giving 

Diurnal  motions  —  26' and  +4'     .     .     .     .     for  lat.  —26°. 
and  it  will  be  noticed  particularly  that  we  have  here  a  total  movement  over  42  degrees. 

830.  A  normal  spot  of  moderate  size  divides  in  two.  On  consideration  of  the  diagrams 
and  particular  points  observed,  it  appears  that  the  only  way  of  deducing-  the  motion  cor- 
rectly in  this  instance,  is  by  comparing-  the  single  position  of  Sept.  30th  with  the  mean 
of  the  two  nuclei  of  October  Gth.

I  suspect  the  longitudes. 

848.  Refer  to  the  diagrams.  Two  spots  near  tog-ether  but  still  separated,  coalesce  and 
are  contained  within  a  considerably  extended  penumbra,  which  afterwards  again  divides, 
and  we  have  finally  the  two  detached  spots  at  about  3  degrees  distance  apart.  Notice 
the  rotation  (left-handed  in  the  diagram)  of  the  line  of  direction  joining  the  two  centres. 
The  figures  give  a  rotation  of  about  4  degrees  per  diem.  The  drifts  may  be  inferred  from 
the  following  adopted  mean  positions.

The  last  observation  of  C  is  opposed  to  its  identity  with  877.  With  respect  to  A  and  B  it 
may  be  more  correct  to  remark  that  the  motions  of  839  and  842  are  shown  by  the  above 
observations  to  be  arrested.     These  two  spots  concurrently  give

It  is  improbable  that  two  such  similar  spots  so  similarly  situated  in  so  rare  a  position  should 
not  be  the  same,  and  yet  the  observed  motions  are  clearly  opposed  to  their  identity,  and 
it  is  most  unusual  for  a  spot  on  the  equator  to  remain  visible  beyond  three  or  four  days. 
It  seems  preferable  to  suppose  them  different  and  treat  them  separately,  on  the  greater 
probability  of  the  case  being  one  of  repetition  or  renewal  of  outbreak.     In  which  case

MR.  CARRINGTON'S    OBSERVATIONS 


937.  The  last  three  observations  of  the  small  spot  which  survives  the  group  might 
perhaps  be  compared,  but  the  result  would  not  be  beyond  objection. 


988.  I  reject  the  two  first  observations.  The  following  observations  were  made  on  the 
"  preceding  "  spot  of  the  two,  which  will  not  affect  the  result,  as  the  distance  appears  to 
have  remained  unchanged  throughout.

Before  assembling  the  foregoing  results  for  final  discussion,  I  have  to  add  one  other 
observation  from  a  foreign  source,  on  account  of  the  high  latitude  to  which  it  relates. 
It  was  communicated  to  me  by  Professor  Peters,  of  Hamilton  College,  Clinton,  New

York,  and  was  made  by  him  at  the  Observatory  at  Naples  in  the  year  184G.  The  spot 
observed  was  nuclear,  and  of  a  form  generally  round,  and  was  followed  first  by  one  and 
then  three  small  detached  spots  at  some  distance.  From  the  observations  sent  me,  by 
reduction  with  the  elements  used  throughout  for  my  own  observations,  1  have  found 
the  following  results,  arranged  as  in  the  Table  of  Eedhill  observations.

I  know  of  no  other  spot  reliably  observed  as  yet  in  so  high  a  latitude.  The  next  in 
order  appears  to  be  my  observation  of  a  group  in  lat.  45°  South,  which  will  be  found 
under  No.  290. 


I  next  extract  and  arrange  in  a  table  all  the  diurnal  motions  above  deduced,  placing 
them  in  order  of  latitude  from  North  to  South,  and  under  each  degree  of  latitude  in  order 
of  date.  The  results  are  further  written  in  three  columns.  In  the  first  are  placed  all 
results  of  well-observed  normal  spots  and  of  double  rotations,  in  the  second  results  of  less 
but  of  tolerable  average  value,  relation  being  had  to  the  number  of  observations  and  the 
interval  over  which  they  extended,  and  in  the  third  column  results  of  decidedly  inferior 
value.

MR.  CARRINGTON'S    OBSERVATIONS 


It  is  desirable  in  the  next  place  to  take  approximate  means  of  the  above  single  results, 
in  order  to  inspect  the  probable  result  of  the  inquiry,  and  judge  of  the  further  treatment 
required.  I  therefore  conjecturally  assign  the  weights  4  and  1  to  the  results  in  columns 
I  and  II.  respectively,  and  in  a  first  solution  reject  III.  altogether.  This  treatment 
leads  to  the  following  table  of  approximate  mean  drifts.  The  sign  +  in  latitude-motion 
indicates  increasing  latitude  or  motion  towards  the  Pole  in  each  hemisphere,  as  before 
stated.

Inspection  of  the  foregoing  table  shows  at  once  that  the  diurnal  motions  in  longitude 
are  subject  to  a  well-marked  law  of  variation  depending  on  the  latitude,  while  it  is  not 
apparent  that  the  motions  tabulated  for  the  latitude  are  anything  beyond  the  accidental 
differences  of  observation.     Trial  readily  shows  that  no  parabolic  curve  or  expression  of 


OF  SOLAR  SPOTS. 


221 


the  form  a  sin  I  or  a  sin2  /  will  satisfy  the  ahove  values  ;  but  that  the  whole  table  of 
results  for  longitude  may  very  fairly  be  represented  by  the  expression 

+  14'   — 165'  .  sin  *  2 

which  expanded  gives  the  following-  values  :

It  will  be  remembered  that  these  values  correspond  to  an  assumed  general  period  of 
Rotation  of  25-380  mean  Bolar  days,  or  to  a  general  Rotation  of  14°  11'  per  solar  day, 
a  value  which  is  now  shown  to  apply  only  to  the  latitude  of  14°  N.  and  S. 

I  now  proceed  to  a  more  accurate  discussion  of  the  individual  results  first  tabulated. 
The  approximate  solution  first  obtained  affords  the  means  of  comparing  each  separate 
result  of  columns  I.  II.  and  III.  with  an  approximate  result  derived  from  the  whole,  of 
averaging-  the  differences  and  deriving  the  weights  suitable  to  be  employed.  Having 
performed  this  operation,  I  have  found  that  the  mean  error  of  a  singie  result  in  column  I. 
is  5'-5,  whether  derived  from  a  singie  or  from  two  rotations  (confirming  my  previous 
belief,  on  which  I  ventured  so  to  class  them),  that  the  mean  error  of  results  in  column  II. 
was  13',  and  of  III.  was  10'.  The  proper  weights  to  apply  to  the  results  of  the  three 
columns  would  accordingly  be  33,  6  and  4  respectively,  or  4,  I  and  k.  It  will  be  suffi- 
ciently near  and  more  convenient  to  use  the  weights  10,  2  and  1.  The  mean  errors 
which  lead  to  this  rule  accordingly  indicate  that  the  results  of  column  III.  are  not  so 
inferior  to  those  of  column  II.  as  I  at  first  supposed,  and  that  the  provisional  weights 
employed  in  combining  the  results  of  I.  and  II.  were  as  nearly  as  possible  correct. 
Were  it  not  that  the  result  under  discussion  is  one  of  the  chief  objects  of  the  present 
research,  a  repetition  of  the  process  performed  above  would  be  hardly  worth  the  doing. 
However,  to  elieck  the  former  result  and  employ  all  the  data  of  observation,  I  form  the 
following  table  with  the  weights  just  found.

In  the  above  table  it  will  be  remarked  that  there  is  more  distinctly  a  trace  of  motion  in 
latitude,  the  sijnis  beino-  on  the  whole  4  for  latitudes  hio-her  N.  or  S.  than  20°,  though  the 
daily  polar  motion  between  20°  and  40°  of  latitude  on  an  average  does  not  exceed  2',  a 
quantity  which  could  only  be  deduced  from  the  totality  of  a  larg'e  number  of  single 
results.  Between  the  parallels  of  10°  to  20°  the  motion  in  latitude  is  evidently  very 
small ;  but  the  signs  are  generally  negative  and  a  feeble  tendency  towards  the  Equator 
of  about  1'  per  diem  is  indicated.  Within  10°  of  the  Equator  on  either  side  no  reliable 
motion  in  latitude  appears  to  exist,  the  signs  varying  much  and  the  mean  results  being- 


OF   SOLAR  SPOTS.

of  less  weight.  It  may  however  be  inferred  from  these  conclusions  that  elements  of 
rotation  will  be  best  based  on  observed  differences  of  latitude  between  about  8  and  18 
degrees  of  latitude  in  either  hemisphere,  pairing'  them  together  in  sets  of  two,  one  North 
and  one  South. 

We  cannot  for  the  motion  in  longitude  do  better  than  compare  the  above  revised  table 
with  the  expanded  table  of  the  expression 

.  .       J. 

+  14   —  105  .sin   *  I. 

using  the  latter  as  a  normal  curve,  and  determine  a  series  of  equidistant  normal  errors, 
with  due  re°*ard  to  the  weio-hts.

In  column  A  I  have  exhibited  the  residual  errors  of  the  empirical  solution 

x 
865'  +    165'.  sin  4  /. A 

and  in  column  B,  those  of  the  expression 

865'    +     165'.  sin*   (/-  i°)  .         .         .         B 

The  errors  are  on  the  whole  reduced  by  the  additional  assumption  that  the  Equator  of 
equal  parallel  rotation  differs  by  1  degree  from  the  true  Equator,  and  the  solution  is 
probably  as  good  numerically  as  it  is  possible  to  find  one,  and  very  closely  represents  the 
total  results  of  observation. 


OF  SOLAE   SPOTS.  225 

Respecting;  expression  A,  in  which  it  is  assumed  that  the  motions  are  equal  at  equal 
distances  from  the  Equator  North  or  South,  it  has  further  to  be  remarked  that  the 
assumed  constant  865'  requires  no  sensible  correction,  the  sum  of  the  +  errors  multiplied 
b}r  their  weights  being-  sensibly  equal  to  that  of  the  —  errors  similarly  multiplied  by 
their  respective  weights. 


In  the  last  place,  as  the  results  for  motion  in  longitude  are  sufficiently  numerous,  1 
have  thought  it  desirable  to  divide  the  whole  into  two  portions,  and  to  institute  for  each 
hemisphere  a  comparison  of  the  motions  of  g-roups  before  number  400  with  those  after. 
The  mean  difference  for  each  hemisphere  has  been  calculated  by  the  following  formula.' 

If  a  i  be  the  mean  motion  and  m1  its  weight  for  g-roups  before  400  of  any  one  degree  of 
latitude,  bl  the  mean  motion  and  nx  the  weight  for  the  groups  after  400  of  the  same 
degree  of  latitude,  the  weight  of(bl  —  ax)  the  difference  between  the  mean  motions  before 
and  after  400  of  that  degree  is  J"i  •  wi  ,  and  the  mean  difference  for  all  the  observed 
latitudes  is

with  weight  the  same  as  the  denominator. 

In  this  manner  I  have  found  for  the  North  Hemisphere  the  difference  +  0'-94  with 
weight  114,  and  for  the  South  Hemisphere  the  mean  difference  —  2'*7  with  weight  92  : 
and  therefore  for  the  two  combined  —  0'#7  with  weight  207.  The  quantity  is  too  small 
to  be  regarded  as  anything  but  a  necessary  conclusion  of  a  numerical  process,  and  the 
signs  come  out  opposed  for  the  two  hemispheres.  Still  I  state  the  result  of  the  exami- 
nation, such  as  it  is.

226  MR.  carrington's  observations 


SECTION     IV, 


Investigation  of  the  Corrections  required  by  the  assumed  Elements 
of  Position  of  the  Sun's  Pole. 


Having  no  doubt  from  the  commencement  of  this  work  that  the  elements  adopted  for 
provisional  use,  namely, 

I  =  7°.  10',  and  N  =  74°.  30',  for  1854-0, 

were  very  nearly  correct,  I  have  never  contemplated  the  necessity  of  starting-  anew  with 
every  satisfactory  series  of  observations  as  a  fresh  basis  for  founding-  a  set  of  elements 
upon ;  but  I  have  throughout  expected  that  a  proper  treatment  of  a  large  number  of 
series  carefully  selected  from  the  stock,  would  lead  me  by  a  suitable  differential  method 
to  a  final  correction  of  the  elements  on  which  some  considerable  reliance  might  be 
placed. 

It  is  not  easy  to  assure  oneself,  in  examining  the  grounds  on  which  previous  elements 
rest  that  the  precaution  has  been  taken  of  rejecting  as  unsuitable  data  spots  of  abnormal 
form,  changing  figure,  or  the  components  of  groups.  The  frequent  instances  given  in 
preceding  pages  of  this  work  of  the  mutual  action  of  parts  of  groups,  whether  large  or 
small,  and  inspection  of  the  plates  of  illustration,  will  supersede  the  necessity  of  specially 
pointing  out  why  in  selecting  data  for  the  correction  of  the  assumed  position  of  the 
Pole,  it  is  indispensable  to  exercise  a  certain  discrimination,  and  as  nearly  as  possible 
confine  oneself  to  continuous  series  of  small  well-defined  single  circular  nuclear  spots, 
such  as  Nos.  180,  194,  207,  291,  478,  &c.  If  single  dots,  such  as  No.  59,  without 
penumbra,  were  frequent  and  of  sufficient  duration,  they  would  be  still  preferable  as 
offering  more  definite  centres  for  observation,  but  these  objects  rarely  remain  visible  for 
more  than  two  or  three  days ;  and  the  same  consideration  induces  one  to  include  some 
normal  spots  of  larger  size  than  a  fastidious  choice  would  approve,  because  they  have 
the  advantage  of  greater  permanence  over  the  very  small  ones.  In  endeavouring-  on  the 
one  hand  to  retain  all  admissible  data,  and  to  reject  all  groups  affected  by  internal 
mutual  actions,  I  find  the  following  86  series  of  observations  alone  remain  out  of  the 
whole  number  observed.  The  numbers  are  recopied  here,  partly  for  convenience  of 
reference,  partly  because  a  reader  could  not  without  reference  to  my  original  memoranda 


OF  SOLAR  SPOTS. 


227 


in  all  cases  select  the  proper  spot,  partly  because  the  longitudes  from  the  Node  are  here 
required  as  data,  and  partly  because  in  a  few  cases  a  small  correction  has  been  made  in 
the  latitude  for  an  estimated  amount  (indicated  by  an  asterisk)  of  observed  change  of 
form.

It  does  not  require  much  consideration  to  see  that  the  effect  of  a  moderate  error  of 
position  of  the  Pole  as  assumed  in  the  reduction,  will  chiefly  be  felt  in  the  latitudes, 
while  the  deduced  longitudes  will  be  affected  by  a  very  small  and  nearly  constant 
amount,  and  consequently  that  the  inequality  produced  in  the  North  Polar  Distances 
will  be  the  best  foundation  for  the  desired  corrections.  If  a  circle  be  drawn  on  paper 
representing-  any  true  parallel  of  latitude,  the  centre  being-  the  true  pole,  and  any  position 
of  the  false  pole  be  assumed,  the  general  value  of  the  inequality  is  at  once  seen,  and  the 
relative  position  of  the  longitude  at  which  the  inequality  vanishes  or  becomes  a  maximum. 
But  the  exact  relations  are  found  as  follows : 


Let  K  be  the  pole  of  the  Ecliptic 
P  .  .  .  .  Sun's  true  Pole 

P' assumed  Pole 

N'.  .  .  .  assumed  Node 

(and  .'.    N'PK  =  90°) 
PK  =  I,     P'K=I',     and  P  K  P'=N-N'. 

Let  S  be  a  Solar  Spot 

PS  =  8  ,     FS  =  S'  , 
then 

8'-S=F  Q=PF.  cos  (PFN  +  NF'S) 

=  PF.  cos  PFN'.  cos  a'-PP'.  sin  PP'N'.  sin  a' 
=X.  cos  a'  — Y.  sin  a         .         .      suppose 


OF   SOLAR  SPOTS.  033 

where  a  is  the  computed  longitude  of  the  Spot  from  the  assumed  node,  as  given  in  my 
principal  catalogue  of  positions,  and  extracted  in  the  series  recopied  above  from  it. 

If  X  and  Y  can  be  found  from  a  series,  or  from  many  combined  series  of  observations, 
the  inequality  is  readily  found  from  the  relations 

PP'  =  a/x-  +  Y* ,  tan  PP'  N'  =  -|r 

and  inasmuch  as 

X  =  PP'.  cos  PP'N'  =  PR  =  ( N  -  N' ).  sin  I, 
Y  =  PP'.  sin  PP'N'  =  PR  =  ( I  -  I' ), 

the  following'  give  the  true  elements  : 

I  =  I'  +  Y  , 

N  =  N'+  X  .  cosec  I. 


We  have  to  consider  next  in  what  way  these  quantities  X  and  Y  can  most  advantage- 
ously be  found  from  the  Avhole  of  a  number  of  separate  series  of  Spots,  affected  each  by 
errors  of  observation  and  individual  proper  motions ;  and  at  the  outset  it  may  be  well  to 
recognize  that  with  such  data  as  floating  objects  visible  on  a  fluid  surface  but  for  a  few 
days  at  a  time,  the  problem  can  only  be  defined  to  be,  '  To  find  that  position  of  Tole 
which  shall  the  best  reduce  these  motions  to  parallelism,  and,  if  any  systematic  drift 
towards  either  Pole  shall  be  found,  to  symmetry  with  respect  to  the  concluded  Equator.' 

I  will  first  give  a  specimen  of  the  treatment  of  a  single  series  of  observations. 
Group  50. 

Let  176-54  be  taken  as  origin  of  time,  +  io.°  20'  +  d  (a  small  unknown  quantity)  the  true 
latitude  at  this  time,  and  —  the  change  of  latitude  in  ono  day  caused  by  proper  motion, 
necessarily  supposed  uniform  throughout  the  observations  in  the  absence  of  knowledge  to 
the  contrary,  or  of  any  law  of  variation.  Tho  true  latitudo  at  any  other  timo  will  be 
+  io°.  20'  +  d  —  —  .  (£—176-54)  ,  and  by  our  formula  this  is 

=  D'  +   (X.  cos  a   —  Y.  sin  a'). 
"We  can  therefore  from  the  formula 

X.  cos  a  —  Y.  sin  a'  =  d  +  (io°.  20'—  D')  H .  (176-54  —  .') 

form  an  equation  of  condition  from  each  observation. 

Thus,  from  series  50,  we  have  the  following 

—  -792.x  —   -6i2.Y  =  d  —  o'  +  -395.  A 

—  -911.x  —   -414.  Y  =  d  +  7   +  -302 .  A 

—  -980.x  -   -182. Y  =  d  +  7    +  -20I.A 

—  -996.x  +   -071.  Y  =  d  —  6   +  -ioo.A

Retaining'  A  on  the  right  hand  side  and  solving  these  equations  by  the  method  of  mini- 
mum squares,  there  result 

X  =   +  8'75  -  I,035  •  A 

Y  =    +  4-00  —  0-488  .  A 

from  which  we  see  that  if  A  =  4-  8',  or  if  there  is  a  proper  motion  of  only  0'*8  per  diem 
towards  the  equator,  the  signs  of  the  corrections  change,  and  this  is  a  very  small  and 
possible  quantity. 

Take  an  equidistant  South  series,  No.  59.  As  before,  let  A  indicate  motion  South- 
wards.    By  precisely  similar  steps,  we  shall  find  from  this  series, 

X  =   4-  2,-3i  —  0-511  .  A 

Y  =    +   3-86  -  0-780  .  A 

If,  in  summing'  up  a  number  of  such  results,  we  simply  neglect  the  effect  of  A,  by  writ- 
ing zero  for  it  in  each  equation,  we  derive  a  mean  result  which  for  the  above  will  be 
simply 

X  =   4-  5'S3    ,    Y  =   +  3''93 

If,  on  the  other  hand,  we  assume  that  the  values  of  A  depend  on  the  latitude,  and  in 
equal  latitudes  have  equal  and  opposite  signs,  we  should  then  divide  out  the  co-efficients  of 

A,  and  write  our  results  thus — 

+   0-970  .  X  =    +   8-40  —   A1 

4-    1-957  •  X  =    +   4-52   -   A2 


similarly 

whence  adding  and  writing- 


+   2-050  .    Y  =    +   8-20  —   A2 
+    1-265  .   Y  =    4-  4"89  —   A2 


A,    +    A2  =   o

The  method  of  procedure,  which  I  have  here  applied  to  two  series,  might  be  applied

to  numerous  pairs  North  and  South,  but  another  obstacle  will  be  found  to  occur,  in  addi- 
tion to  the  great  labour  of  the  process,  namely,  that  when  a  certain  number  of  satisfac- 
tory pairs  of  series  have  been  chosen  from  out  of  the  86  at  disposal,  the  others  will  not 
pair  tog-ether  in  any  satisfactory  manner,  two  and  two,  with  due  regard  to  weight,  and 
we  seem  to  require,  at  the  same  time,  a  readier  and  more  general  style  of  treatment. 

Such  is  the  following,  which  I  finally  adopted.  Each  series  of  observations  fields  a 
certain  number  of  observed  values  of  8'  corresponding  to  observed  values  of  a',  from 
which  we  can  obtain  a  series  of  equations 

$'a   —  S  =  X  .  cos  a  —  Y  .  sin  a 

8^    —   8   =   X  .  cos  b   —  Y  .  sin  b 

B'c    —  S  =  X  .  cos  c  —  Y  .  sin  c 

from  which,  by  subtraction,  we  can  form  the  following  equations,  independent  of  8,  the 

actual  North  Polar  Distance, 

S^    —   B'a    =  X  .   (  cos  b  —   cos  a  )    —  Y  .  (  sin  b   —   sin  a  ) 
S'c    —  $'b    =   X  .   (  cos  c   —  cos  b  )    —   Y  .   (  sin  c   —   siu  b  ) 

and  determine  values  of  X  and  Y  from  the  successive  differences  of  8'  as  observed.  In 
order  to  determine  the  values  of  X  and  Y,  which  result  from  the  totality  of  a  large 
number  of  series  of  observations,  it  is  most  convenient,  however,  to  interpolate  other 
values  of  8'  for  previously  selected  values  of  d  at  equal  intervals,  such  as  30  degrees, 
to  tabulate  the  observed  differences  of  8'  for  each  snics  for  these  angles  and  to  take  the 
mean  values  of  (  8\  -  8'a  )  ,  (  8'c  -  8'b  )  ,  etc.  as  the  data  for  the  determination 
of  the  values  of  X  and  Y.  The  table  which  follows  will  render  the  process  perfectly 
clear,  and  the  only  point  requiring  further  explanation  is  the  process  of  interpolation  fol- 
lowed, which  it  will  be  seen  has  the  advantage  of  getting  rid  in  a  degree  of  the  inevit- 
able errors  of  observation.  Suppose  we  have  a  series  of  observed  numbers  for  equal 
internals  of  time,  such  as  the  following  in  the  first  line  below,  take  their  means  two  and 
two,  as  in  the  second  line,  and  again  the  means  of  the  first  means  two  and  two,  as  in  the 
third  line, 

454     ,     478     ,     490     ,     S36     >     588     ,     6t4»  etc. 

466     ,     484     ,     513     ,     562     ,     601,  etc. 

475     >    498     ,     537     .     58^,  etc. 

it  will  be  apparent,  particularly  on  laving  down  these  values  graphically,  that  by  the 
substitution  of  the  numbers  in  the  third  line  for  those  in  the  first  line,  the  irregularities  of 
the  values  (supposed  to  be  observed  values)  are  in  a  great  measure  mutually  destroyed, 
while  the  law  of  progress  is  left  intact.  I  have  applied  this  process  to  the  observed  values 
of  8'  for  each  series  of  observations  of  the  spots  selected  as  data  for  elements,  by  laying 
them  down  graphically,  interpolating  between  them  two  and  two  with  the  observed 
unequal  differences  of  a,  and  in  the  second  taking  of  means  found  values  of  8'  correspond-

nig*  to  equal  differences  of  a',  namely,  at  each  30  degrees.  The  trial  of  any  one  case  will 
show  at  once  that  there  is  no  difficulty  in  so  doing-.  In  this  manner  I  have  substi- 
tuted for  the  original  series  of  observations  the  following*  interpolated  series,  in  which  the 
arrangement  follows  the  order  of  North  Polar  Distance  and  North  Polar  Distances  are 
substituted  for  latitudes  as  required  by  the  formula.

On  multiplying-  each  of  these  mean  values  by  its  weight,  summing  the  whole,  and 
dividing  by  the  sum  of  the  w eights,  we  find  a  mean  excess  of  — 1'-5,  which  would  imply 
that  on  the  whole  there  is  an  average  tendency  towards  the  North  Pole  of  90  seconds  in 
the  time  during  which  the  Sun  rotates  through  30  degrees.  I  can  only  regard  this  as  a 
fictitious  and  non-real  result  arising  from  the  omission  of  some  small  correction  Avhereby 
the  angles  of  position  come  out  too  great  in  the  first  half  of  any  Spot's  passage  over  the 
disk,  and  too  small  in  the  second  half.  The  omission  of  0,  the  correction  for  non- 
verticality  of  the  bars,  will  not  account  for  the  result.  If  the  correction  to  the  angle  of 
position  had  been 

—   0(|    +    sin2  a  )  instead  of  +    9(1    —   sin2  a) 

the  discrepancy  would  have  been  immediately  explained,  but  the  correction  given  in  the 
text  is  plainly  correct  on  general  considerations  as  well  as  in  its  detailed  proof.  It  is  pos- 
sible that  the  omission  of  the  correction  for  refraction  may  be  the  cause,  in  conjunction 
with  the  circumstance  that  for  the  most  part  the  observations  were  made  after  noon. 
However  this  may  be,  for  I  cannot  now  introduce  this  correction,  inasmuch  as  in  our 
present  inquiry  we  are  only  concerned  with  that  part  of  the  mean  differences  which  follows 
the  law  of  the  sine,  and  presents  an  equal  departure  on  the  whole  on  either  side  of  zero,

from  which,  by  similar  treatment  as  in  the  former  case,  I  find

the  corresponding'  inequality

and  for  true  elements 

I  =  7°  I7'3  >  N  =  73-  28  for  1854-0  . 
It  is  desirable  to  point  out,  what  inspection  will  otherwise  show,  that  the  distribution  of 
the  series  of  spots  selected  as  data,  is  in  each  case  very  uniform.  In  the  case  of  all 
86  groups,  21  series  have  greater  N.  latitude  than  15  degrees,  22  series  lie  between 
15°  North  and  the  equator,  22  other  series  between  the  equator  and  15°  South,  and 
21  series  have  greater  South  latitude  than  15  degrees.  In  the  case  of  the  60  series  of 
superior  character,  30  are  N.  series  and  30  South. 

I  flatter  myself  that  this  method  of  treatment  will  be  considered  at  the  same  time  con- 
venient and  accurate  in  principle,  and  that  the  result  arrived  at  will  be  held  to  have 
superior  weight  as  an  astronomical  determination  to  those  of  the  same  elements  by  my  pre- 
decessors in  this  line  of  inquiry.  The  elements  of  M.  Laugier  were  based,  as  stated  in 
the  Comptes  Eendus  for  1842,  Deuxieme  Cahier,  page  940,  on  29  series  of  observations 
made  and  discussed  by  himself,  and  are  as  follows,

It  is  to  be  regretted  that  his  Memoir,  though  recommended  for  publication  in  the 
Journal  des  Savans  Etrangers,  has  never  been  printed,  and  that  its  future  publication 
remains  still  uncertain,  perhaps  I  should  say  now  improbable,  for  I  believe  his  determi- 
nations to  be  the  best  previous  to  my  own,  and  they  will  be  found  to  lie  between  my  values 
and  the  only  others  which  can  be  placed  in  competition  with  the  two,  I  mean  those  of 
Dr.  Bohm.  The  Elements  of  Dr.  Bohm  are  given  in  his  elaborate  Memoir,  Aus  dem  III. 
Bande  der  Denkschriften  der  Math.  Classe,  &c.  &c.  der  Kaiserlichen  Akademie  zu  Wien, 
1852,  and  are  1  =  6.  50-7  ,  N  =  76.  46-9  for  1833-0  and  depend  on  13  series  of 
observations,  which  the  reader  can  refer  to  if  he  thinks  desirable.  I  will  only  remark 
that  his  process  of  treatment  being  somewhat  involved,  it  is  not  easy  to  examine  the 
details,  and  that  the  use  of  Dr.  Bohm's  values  in  my  reductions  would  have  led  to 
the  very  noticeable  inequality 

8'  -  8  =  3i'-5  .  cos  (  a    +   144.  15  ) 

indicating  with  certainty  the  necessity  of  large  corrections  of  his  Elements  in  the  direction 
of  M.  Laugier's  and  mine. 

Considering-  that  fractions  of  minutes  cannot  as  yet  be  determined,  I  propose  for 
future  adoption  the  Elements

till  clearly  superseded  by  the  superior  means  and  length  of  observation  of  some  succeeding 
Astronomer,  who  can  devote  more  than  eight  years  of  continuous  research  to  the  subject, 
and  take  advantage  of  finer  skies,  and  I  hope  Photograph}-.  I  believe  I  shall  be  not  far 
wrong  in  saying  that  a  sensible  improvement  on  the  above  values  will  not  be  obtainable 
by  an  expenditure  of  less  than  five  thousand  pounds. 


SECTION    V. 


0\   THE  TENDENCY   OF   SPOTS   TO    DIVERGE. 


The  fact  will  be  best  studied  by  reference  to  the  diagrams.  It  appears  to  me  to  be 
only  explicable  by  the  tendency  of  spots  to  break  out  two  and  two  or  to  subdivide, 
coupled  with  a  gyratory  motion  of  their  parts,  which  for  every  spot  in  the  same  hemis- 
phere will  take  place  in  the  direction  of  rotation  around  the  pole  of  that  hemisphere,  or 
what  is  called  right-handed  in  the  South  and  left-handed  in  the  North  Hemisphere. 
The  outer  portions  of  two  contiguous  spots  will  therefore  have  opposed  motions  producing 
mutual  centrifugal  pressure. 

Compare  first  the  following  series  where  the  tendency  is  exhibited  in  mere  dots : 
Spots  10,   114,   165  and  228. 

Next,  the  following  five  instances  of  subdivision  and  divergence: 
Spots   182,  224,  290,  697,  and  813. 

The  following  are  ordinary  cases,  some  very  remarkable,  as  for  instance  183  : 
Groups  22,  Sj,     99,   124,   152,  183,  249,  250,  261,  293,  305,  487,  617, 
629,  645,  687,  706,  707,  752,  811,  894,  9°5>  933;    and   939- 

There  are  cases  in  which  the  absence  of  this  tendency  is  equally  to  be  remarked  : 
See  79,  139,  292,  412,  419,  664,  854,  858,  938,  941,   and   951. 

The  impression  which  these  examples  are  calculated  to  produce  would  be  more  forcibly 
conveyed  if  the  figures  to  which  the  numbers  relate  could  again  be  given  collectively, 
but  the  necessarily  large  amount  of  illustrations  which  the  subject  involves,  forbids 
indulging  in  any  repetition  which  can  be  avoided,  and  I  must  put  the  reader  to  the 
trouble  of  referrino-  to  the  figures  in  their  serial  order.

SECTION    VI. 


On  Recurrence  in  the  same  Neighbourhood. 


I  have  thought  that  an  index  to  such  cases  of  probable  recurrence  as  I  have  noticed 
would  be  desirable,  as  the  possibility  of  the  cause  of  formation  of  a  spot  remaining-  after 
its  disappearance,  and  giving-  rise  to  a  second  and  third  is  a  point  of  some  consequence 
to  the  theory  of  their  origin.  The  variability  of  form  renders  it  almost  impossible  to 
come  to  any  decision  on  which  argument  might  be  based. 

Compare  Groups  58  and  63. — 58  is  a  single  spot  tending  to  extinction,  which  is  succeeded  next 

rotation  by  63,  a  complex  group  in  the  same  neighbourhood  a  little  North. 
144  and  146. — Different  in  the  same  position. 

161  and  172. — One  component  of  172  occupies  nearly  the  position  of  161  when  last  seen. 
167  and  171. — The  first  must  have  disappeared. 
174  and  184. — Very  similar  and  certainly  different. 

179- — The  "  following"  portion  visibly  receives  a  considerable  re-development  in  the  latter  half 
of  its  passage  over  the  disk. 

182  is  followed  by  192  in  the  same  position. 

J83,  194*  204  and  211. — 194  is  probably  identical  with  part  of  183,  but  204  is  a  renewal  after 
entire  obhteration,  and  211  is  a  second  renewal  in  the  same  part. 

193  and  203. — Very  similar  outbreaks.     193  must  have  disappeared  several  days  before  the  first 
appearance  of  203. 

220  and  229. — Examine  the  accession  to  229  and  compare  with  220  B. 

667,  690  and  711. — Seem  to  be  three  successive  outbreaks  in  nearly  the  same  part. 

703  and  723. — Dots  in  nearly  the  same  place. 

704,  724  and  746. — Three  successive  outbreaks. 

817  and  842. — Distinct  outbreaks. 

854  and  940  each  receive  considerable  accessions  in  their  passage  over  the  disk. 


OF   SOLAR   SPOTS.  247 


CONCLUDING    SECTION. 


From  a  desire  to  dismiss  this  self-imposed  task  for  the  present,  which  of  late  has  been 
continued  with  much  personal  inconvenience,  I  forbear  here  to  enter  on  the  evidence 
which  the  motions  of  normal  spots  afford  of  the  existence  and  extent  of  a  refracting 
atmosphere  round  the  Sun.  The  method  has  been  sketched  out  elsewhere  and  an 
example  of  its  application  given.  Much  additional  matter  is  contained  in  this  memoir 
for  following1  on  the  inquiry  at  a  future  time. 

I  equally  forbear  from  theoretical  speculation  on  the  origin  of  the  term  in  the  Rotation 
of  the  Photosphere  depending  on  the  latitude.  The  general  fact  which  it  more  accu- 
rately expresses  of  Rotation  at  the  Equator  faster  than  the  mean  angular  motion, 
however,  appears  to  me  strongly  to  support  the  views  expressed  by  Professor  W. 
Thomson  in  his  memoir  on  the  "  Mechanical  Energies  of  the  Solar  System,"  (Trans. 
Roy.  Soc.  Edin.  Vol.  xxi.)  in  which  a  continued  acceleration  of  the  Sun's  rotatory 
motion  is  shown  to  be  one  probable  consequence  of  the  vortical  motion  of  the  meteoric 
matter  which  is  there  shown  to  be  the  most  probable  source  of  the  Solar  heat  and  light. 
In  the  absence  of  an  impressed  motion  from  some  such  external  source  it  would  be 
expected  that  the  currents  of  the  surface  of  the  Sun  would  resemble  those  of  the  Earth's 
ocean  and  atmosphere,  and  be  Westerly  and  towards  the  Poles  in  the  tropical  latitudes, 
and  Easterly  in  the  higher  latitudes;  the  direction  of  Rotation  in  each  case  being  the 
same,  and  the  Equatorial  region  in  each  the  hottest. 

At  the  end  of  the  series  of  illustrations  I  give  a  Plate  on  which  are  laid  down  to 
scale,  lstly,  the  variations  of  Spot-frequency,  2ndly,  the  variations  of  the  distance  from 
the  Sun  of  the  Planet  Jupiter,  and  Srdly,  the  variations  in  the  Imperial  average  price  of 
wheat  as  published  by  Mr.  Stanton  of  the  Estates  Gazette  Office  in  Fleet  Street.  The 
first  of  these  curves  is  deduced  by  interpolation  from  the  annual  mean  numbers  deduced 
by  Prof.  Wolf  of  Zurich,  from  various  ancient  series  of  observations  which  he  has 
sought  out  and  collected,  and  which  are  given  in  No.  12  of  his  "  Mittheilungen  iiber 
die  Sonnenflecken,"  p  72.  The  extension  backwards  which  Prof.  Wolf  has  thus  given 
to  what  was  previously  known  on  this  periodic  variation  is  extremely  valuable,  and 
presents  a  problem  for  solution  of  very  high  importance,  and  which  has  been  for  some 
years  before  me  as  a  subject  of  thought.  I  purposely  contrast  with  it  the  variations  of 
Jupiter's  Radius  Vector,  as  offering  the  only  approximate  agreement  which  I  have  been 
able  to  perceive.  It  will  be  seen  that  from  the  year  1770  there  is  a  very  fair  general 
agreement  between  maxima  of  frequency  and  maxima  of  Jupiter's  Radius  Vector,  and 


248  MR.  carrington's  observations. 

between  minima  and  minima,  with  such  an  amount  of  loose  discrepancy  as  to  throw 
grave  doubt  on  any  hasty  conclusion  of  physical  connexion.  In  the  two  periods  which 
precede  that  date  there  appears  to  be  a  total  disagreement,  and  although  the  data  for 
frequency  are  less  certain  for  those  years,  yet  the  general  form  of  the  curve  of  Prof. 
Wolf  is  probably  too  well  established  to  admit  of  anything  like  reversion  by  the  addition 
of  other  observations  which  have  not  yet  come  to  hand.  In  this  case,  though  unfavour- 
able to  our  purpose,  it  is  important  to  see  before  us  an  instance  in  which  eight  consecu- 
tive cases  of  general  but  imperfect  agreement  between  the  variations  of  two  physical 
phenomena  are  shown  to  be  insufficient  to  base  any  conclusion  upon,  at  the  same  time 
tbat  they  powerfully  stimulate  further  inquiry  with  the  view  of  ascertaining-  whether  the 
discrepancy  may  admit  of  future  explanation.  I  attach  no  importance  to  the  wheat 
diagram,  but  data  of  this  kind  were  employed  in  an  interesting-  and  original  investigation 
of  the  elder  Herschel  which  has  been  frequently  referred  to  in  subsequent  years.  The 
present  diagram  appears  to  me  rather  to  indicate  that,  concurrently  with  abundant  and 
deficient  crops,  social  and  political  causes  affect  prices  to  an  extent  sufficient  to  destroy 
their  value  for  the  purpose  for  which  he  selected  them.*  Returning  to  the  Jupiter  curve 
and  bearing  in  mind  the  part  which  the  material  of  the  Zodiacal  light  plays  in  the 
opinion  of  Prof.  Thomson,  I  suggest  that  it  deserves  consideration  whether  the  mass  of 
Jupiter  may  not  affect  the  variations  of  Solar  Spot-frequency  indirectly  through  his 
possible  intermediate  action  on  the  ring  of  matter  constituting  the  appearance  termed  the 
Zodiacal  light.  If  this  view  should  be  thought  of  any  weight  it  will  be  seen  to  be 
desirable  that  in  establishing-  a  special  station  for  the  further  observation  of  Solar 
phenomena,  a  situation  should  be  selected,  where  at  the  same  time  observations  may  be 
made  under  the  most  advantageous  circumstances  on  this  ring-  of  matter,  of  which  so 
little  that  is  exact  is  yet  known,  and  this  leads  at  once  to  the  conclusion  that  such 
a  tropical  station  as  Captain  Jacob  had  intended  to  occupy  in  India  is  the  most 
suitable  for  the  purpose.  There  at  an  elevation  of  5000  feet  above  sea,  almost  con- 
tinuous observations  might  be  made  on  both  phenomena  simultaneously,  and  in  no  other 
than  a  similar  position. 

It  hardly  needs  the  addition  of  my  opinion  that  in  future  observations  of  the  Sun  and 
his  Spots,  the  methods  of  photographic  registration  and  of  Nature  printing  of  the 
results,  brought  to  a  high  state  of  completeness  and  efficiency  by  Mr.  De  la  Rue  are 
obviously  those  to  be  followed,  rather  than  the  method  of  sketching-  and  time  observations 
which  I  have  employed,  while  those  improved  processes  were  not  yet  worked  out.  I 
refer  particularly  to  an  admirable  specimen  recently  published  by  Mr.  De  la  Rue  in  the 
Monthly  Notices  of  the  Royal  Astronomical  Society. 

*  It  will  probably  be  noticed,  that  no  previously  uninformed  person  could  from  the  curve  infer  the  year 
of  the  abolition  of  the  Corn  Laws,
