PREFACE 



THE Commiffioners of Longitude, in pur- 
luance of the Powers veiled in them by a 
late Ad of Parliament, prefent the Publick with 
the Nautical Almanac and Astronomical 
Ephemeris for the Year 1768, being the Se- 
cond ImpreflTion, to be continued annually -, a 
Work which muft greatly contribute to the Im- 
provement of Aftronomy, Geography, and Na- 
vigation. This Ephemeris contains every Thing 
effential to general Ufe that is to be found in 
any Ephemeris hitherto publifhed, with many 
other ufeful and interefting Particulars never ycc 
ofFered to the Publick in any Work of this Kind, 
The Tables of the Moon had been brought by the 
late Profeflbr Mayer of Gottingen to a fufficient 
Exa6tnefs to determine the Longitude at Sea, w^ithin 
a Degree, as appeared by the Trials of fcveral 
Perfons who made Ufe of them. The Difficulty 
and Length of the neceiTary Calculations leemed 
the only Obftacles to hinder them from becoming 
of gencraf Ufe : To remove which this Ephe- 
meris was made J the Mariner being hereby re- 
lieved from the Ncceflity of calculating the Moore's 
Place from the Tables, and afterwards computing 
the Diftance to Seconds by Logarithms, which 
are the principal and only very delicate Part of the 
Calculus J fo that the finding die Longitude by 

the 



PREFACE. 

the Help of the EpjttMtRi? is now in a Mann:ef 
reduced to the Computacion of the Time, an Ope- 
ration equal to that of an Azimuth, and the Cor- 
re(5Uon of tlieDiftanceon account of Refraction and 
Parallax, which is alfo rendered very eafy by either 
of the Two Methods invented by Mr. Lyons and 
Mr. DuNTHORNE, and publilhcd among the Tables 
trequifite to be ufcd with the Ephemeris. 

'J By Defire of the Comminioners of Longitude I 

'drew up the Explanation and Ufe of the Articles 

^ contained in the Ephemeris, and the Inllrudions, 

with Examples, for finding the Longitude at Sea. 

by the Help of the fame, I alio coUefted and cal- 

■ culated the Sixteen Firft Pages of Tables requifue to 

be ufed with the Ephemeris, and computed the 

Table of proportional Logarithms, which feemed to 

me abfokitcly neceffary to clear this Method of any 

remaining Difficulty •> and added Explanadons of all 

the Tables, and a Correction, p. 49 and 50, which 

may be applied by the Curious to the Effect of 

Refraction on the Moon's Diftance from a Star, 

found by Mr. Lyons, or any other Method, on 

account of the Barometer and Thermometer. 

All the Calculations of the Ephemeris relating 
to the Sun and Moon were made from Mr, Mayer's 
laft manufcript Tables, received by the Board of 
Longitude after his Deceafe, which have been 
printed under my Infpe6tion, and will be publilbed 
Ihortly. The Calculations of the Planets were 
made from Dr. Hallev's Tables-, and thofe of 
the Eclipfes of Jupiter's Satellites from the Tables 
of Mr. Wargentin, publilhcd by M. De la 
JLande in 1759, except thofe of the Fourth Satel- 
lite, 



P il E F A C E. 

lite, which were calculated from the Tables of the 
fame further improved by Mr. Wargentin, arid 
publifhed alfo by M. De la Lande in the Con- 

NOISSANCE D£S MoUVEMENTS CELESTESOf I 766. 

AH the Articles of the Ephemeris were com- 
puted by Two feparate Eerform, and examined i)y 
a Third, except the Moon's Longitude, latitude. 
Right Afcenfion, Declination, Semidiameter, and 
Parallax, which, for Noon, were computed by One 
Perfon, and for Midnight by another:, and the 
Truth of thefe Calculations afcertained by means 
of ©iFerences, which, for the "Moon's XiOngitude, 
were carried as far as the Fourth Order. .

JA.STRON0MICAL and Nautical Eehemeris; 



IT may be proper firft to prcmife, llaat all tlie Cakuladons 
are made according to apparent Ttme by the Meiidian^af 
the Royal Obfervatory at Greenwich. Tliey are likewifc 
adapted to apparent Noon, except where they are othervvife 
diflingiiilhed, as the Eclipfes and Configurations of Jupiter's 
Satellites, the Moon's Places, iSc, computed for Midnigiif* 
and tlie Diftances of tlie Moon from the Sufi and Stars for 
every third Hour; which are all computed to the apparent 
Times fet down. 

Apparent Time is that deduced iinmediately from tlie Sun, 
whether from the Oblervation of his parting the Meridian, from 
his Altitude obferved ataDiftance from the Meridian, or from 
Jiis obferved Rifing or Setting. This Time is diflcrent from 
that ihewn by Clocks and Watches well regTiilated at Land, 
which is called equated or mean Tune. Tliis will be ex- 
plained when we come to treat of the Equation of Time. 

The Day is here fuppofed, according to the Method of Af- 
tronomers, to bcein at Noon, or 12 Hours later tlian the 
civil Day of tlie lame Denomination, and to be counted up to 
24 Hours, or the fucceeding Noon, wlicn the next Day begins. 
Thus the Day of tJic Month and the Hour of the Day are the 
fame in this Method as in the civil Account at Noon, and 
from N*oa till Midnieht ; but from Midaifht tiU Noon they 
U differs 




[ 146 ] 

dtfTer ; for wliercas m the civil Account a frcfli Day is fap- 
pofed to begin at Midnight, aiid the Hours to begin over 
again, in this Metiiod tlie Day is itill continued beyond Mid- 
night, and the Reckoning of the Hours is continued up to 24, 
Thus lIveDlftances put down to Janvary 10, 1; Hoursr*bek)ng 
to January 1 1 at Three in the Morning by civil Reckoning. 

There are 12 Pnges for every Month. The fidt CaluiTtn of 
tlie firft page of each Month contains the Day of the Mo«ith; 
the Second, the Day of the Week exprclfed concifely by the 
initial Letter or Letters, Su. ftuiding for Sunday, M. for 
Monday, Tu. for Tucfday, W. for W'ednefdiy, Th. for 
Thurfday, F. for Friday, and Sa. for Saturday : Tlie third Co- 
lumn exhibits the Sundays and Feftivak of tlieQiurch of Eng- 
land, and other remarkable Days: The laft Column fliews at 
Top the MfVin's Phafes, or the Times of new and full Moon, 
and of the hrft and lafl Quarter, or two Quadratures with tlie 
Sun : Beneath are contained mifccllaneous Phaenomenui, name- 
ly, Eclipfes of the Sim and Moon, and Occultations of Planets 
or fixed Stars not lefs tlian the fourth Magnitude, by the Moon, 
as they Ihould happen at Greenwich by the Tables-; the Coi»« 
jiinftions of the iVIoon with all Stars not Icfs than tlie fourth 
Magnitude, which can be Ocaultations any where on the 
Globe, between the Latitudes of 60°. North and 40°. South : 
Tlie Conjundtions, Oppofitions and Quadratures of the fupcrior 
PIsncts with the Snn ; and the Conjundlions and greatell Elon- 
gations of the inferior Planets from the Sun, the Entrance of 
Mie Sura Into tlie ieveral Signs, and any other remarkable Phz- 
uoniena. 

The Start; are exprefled by Bayer's Charafters of Reference. 
The Conjunction of the Moon or a Planet with a Star, is. 
iJenoted by prefixing the Cliarafter of tlic Moon or Planet 
to that of the Star, the Time of the Conjunrtion being 
placed immediately after. The Cafe is the fame with Rcl'pedt 
to tlie Occuhation of a Star or Planet by the Moon, only this is 
furtlier difliiigulflicd by the Addition of Im. or Inunerfion, to 
%nily the Difappearance behind the Moon; and Em. or Emcr- 
fon, lofignify tlieRc-appearaiiceofthelamc. ThusB"* j /* yf

The Occiiltations fet down are tliofe only vifible at OreeJi. 
wich ; and tlic Circumflaiices will not dlfier very widely .ia 
nioft Parts of llie Kingdom; but in very dillant Places tiiey 
will dJrter very much, owing to the Change of the Moon's 
Parallax, or it inay l^econie no Occultation at all : The like 
iMy be faid of Ecltpfes of the Snn, 

Eclipfes of tjie Sun, and Occultations of fixed Stars by the 
Moon, if obferved in Places whnfe Latitude and Longitude 
are well determined, may be applied to the Correction of 
the lunar Tables ; but if made in Places whofe Latitude only 
is ivell known , may be applied to the Detcmiination of iJie 
Longitude of the Place ; but for this Purpofe an :JCcurate Cal- 
culation nnifl be made of the Monn's Parallaxc; in Longitude 
and Latitude, whicii makes this Metliod of fettling the Lojijfi- 
Tudes of Places, though a very accurate one, lefs convenient 
in Ufe for PerfoJis not much verfed in aftronomical Calcula- 
tions. Howe\-er, this oiiglit not to difcourage Travellers or 
Mariners from endeavouiing to make thefc OWcrvations as 
often and as carefidly as poilible, when they fhall happen to 
be at any Place uhofc Longitude they have Rcafon to tliink 
hai not been at all or but indifferently determined ; fince the 
neccffary Calculations may be made at any Time afterwards by 
thcmfelves, at kifure,or referred to tlie Skill of Allrouomers 
and Matiiematicians. 

Eclipfes of lire Moon are not liable to this Inconvenience ; 
the Longitude of any Place, where aii Eclipfe has been ob- 
fcrved, being deduced inunediately by taking the Difference 
of the Time of the Obfer%'atton ana that let down in the 
Ephcmeris, and converting it into Degrees, at tlie Rale of 
Ij *o One Hour, i^c or more briefly by Table Pages 6. 7, 8. 
of the Tables requifite to be ufed with the Ephemcris. But 
ns the Beginning or Ending of an Eclipfe of the Moon cannot 
be generally oblerved nearfrthan Ojie Minute, and fonictijnes 
Two or Three Minutes of Time, the Longitudes of Places can- 
not be certainly detemuned by this Method from a fuiglc 
Obfeivation of tlie Beginning or End nearer tlian a Degree. 
It is tmneccflar}- In mention thai tven this Point of Exadtnefs 
will oficn be of great Scr\'jce. If both the Beginning and 
End of tlie Ecliiii? be obferved, a comiderably greater De- 
gree of Exnflncfij will be attained. 

Tlie Conjnnftions of tlie Moon with the Planets, or fixed 
Stars nor lefs than tlie fourtli Magnitude, which may prove 
Occultations in fome inhabited Parts of the Globe, are evi- 
y d(?figncd to inftrutt Mariners or Tiaveller* to look out 
U z frequeiUiy

[ 148 ] 

frtqueiitly for fuch Obfervations; which if they happen t 
j)rove Occultationv, and aie carefully obfcrved, will afford a 
certain Means of dctcmuning the Longitude cf the Pla<:e of 
Obfervatlon. 

The Days of the Oppofitions, Qnadrahires, i^c. of the Pla- 
nets with Refpett to the Sun, are Times at which they ouglit 
to be obferved in fixed Obfervatories, for fettling the Elements 
of their Orbits by a Series of feveral Years Obferrations. 

The Two firft 0>iumns of the Second Page of the Month 
contain the Day of tlie Monlh and Week as before; next 
follow the Sun's Longitude, right Afcenfion in Time, Decli- 
nation, and the Equation of Time, with the Diflerence from 
Day to Day. 

The Longitude of tlie Sun is made ufe of in moft of the 
fucceeding Calculations of the Eplienieris.. and may ferve 
either to verify them, or to make other fimilar Calcula* 
tions at a different Time of the Day. Particularly it may ferve 
with the Help of the Moon's Longitude, to find the Difiance 
cf the Moon from the Sun at any Time, independent >i the 
Dillances contained in the Four laft Pages of the Mon.h. To 
find the Sun's Longitude at any Time different from Noon^ 
Proportion miift be made according to its daily Incteafe ; 
Saying as 24MS to the Hour from Noon reckoned by the Me- 
ridian of Greenwich, fo is the daily Variation of the Sun's 
Longitude, to a fourth Number ; which addtd to the Sun's 
Longitude at the preceding Noon, gives the true Longitude 
at the {jiven Time. 

If the Time given ^le that of a Meridiati different from 
Greenwich, it nivill be firft reduced thereto, by adding or 
fubffradting the Difference nf Longitude turned into Time (at 
the Rate of One Hour to 15°, and One Minute of Time to 
1 J Mir.utes, or more briefly by Pages b, 7, and 8, of the re- 
fjuifite Tables) according as the Place is to the WefJ or ta 
the Eaft of Greenwich. Example r Suppofe any one flioiild 
want to know the Sun's Longiuide, January rg, 1767, at 4*'. 
3^/. being in 21° 15', Longitude Eaft of Greenwich. The 
Difference of Longitude turned into Time by Table Page 6, 
is i*". 25^ which fubllracTted from 4^ 35'. becaafe the Place 
is Eaft of Greenwich, leaves 3^ 10'. for the Time reduced to 
the Meridian of Greenwich. The Sun's Longitude the pre- 
ceding Noon is, 9». 2q». iS''. :". and the following Noon is, 
lo'.o". 19'. 4". theDifference is, i«. i'. 2". or 6i'.z". the daily 
Variati»n. Then fay, as 24''. is to 3''. 10', fois6i' z" to 8'. 3", 
Wkicji added to c/.z-j*. i8'.2/'. the S«n's Longitude on the 

precedinjf 



r U9 ] 

preceding Noon, gives 9'. 29*. 26'. j" the Sun's Longitcde at 
tlie Time given. In J ike Manner any other of the following 
Articles is to be found by the Help of the Ephcmcris. 

The Sun's Longitude ferves alfo to compute the Aberration 
of the fixed Stars and Planets. 

The Sun's right Afcenlion in Time is ufeful to the prafti- 
«al Aftronomer in regular Obfer\'atorics, who adjulh his 
Clocks by fidereil Time. It is alfo ufcfiil to htm for convert- 
ing qpparent into fidereal Time ; as fuppofe that of an Eclipfe 
• of Jopiter's Satellites, in order to know at what Time it may 
be expe£led to happen by hh Clocks : For this Purpofe, the 
Sim's riglit Afce»finn at the preceding Noon, together with 
the Increafc of right Afcenfion from Nonn, muft be added to 
the apparent Time of the PliEUomenon fet down in tiie Ephe- 
meris. 

The Sun's right Afcenfion in Time ferves alfo to compute 
the apparent Time of a known Star's paffing the Meridian; 
Thus fubi^raft the Sun's right Afcenfion in Time at Noon 
from the Star's right Afcenfion in Tijpe, the Remainder is 
the apparent Time of the Star's paffing the Meridian nearly; 
fVoni which the proportional Part of the daily Increafc of 
!l>e Sun's right Afcenfion for tliis apparcjit Time from Noon 
being fubftrafted, leaves the corre^fb Time of the Star's paifing 
the Meridian. 

Hence th^ apparent Time may be found from an nbferved 
Altitude of a kjiown fixed Star, fuppofe one contained Page 
J 2 Of 13 of the requifite Tables; .as will be explained herc- 
alter. 

The Sun's right Afcenfion in Time is alfo ufefiil for com- 
puting the Time of the Moon and Planets pafiing the Meri- 
dian, as will be (hewn imder their proper Articles. 

The Sun's Declination is necciTary to find the latitude, 
whether at Sea or Land, from the Meridian Altitude obferved; 
it is alfo lequifite for finding the Latitude from Two Altitudes 
obferved with the Interval of Time menfured by a ^V'^atchi 
it ferves for computing the Sun's Azimuth, having his Alti- 
tude and the Latitude of the Place given, in order to find the 
Va^i.^tion of the Compafs; it Jsrecjitired jointly with the La- 
titude of the Place and the Sun's Imrary Angle to com]nite liis 
Altitude, if ncgle<^tcd to be obferved at the Time of taking riie

from th« Meridian, the Latitude being given ; or to compute 
the Time of the Sun's Setting ov Rifmg; which, though a lefs 
accurate Method than the fonncr of obtiiining the Time, may 
y€t he ufefulvvhcn tljat cannot be had. For a»y ofthefe Pur- 
pofes, the Sun's Declination mull be found to the Time givea 
nearly reduced to tbc Mcridi.in of Greenwich, n'laking Pro- 
portion according to tlie daily Increafe or Decveafe, m like 
Manner as was fhewn with Refped lo the Suii's Xxn>^itude. 

The Equation of Time is a Correflion, which added to or 
fubftrafled from the apparent Time (acoordir;g to its Title at 
the Top of the Column) gives equated or mean Time, cr that 
v/hich fhould be Ihewn by a good Clock or Watch. Ap- 
parent Time is that which takes its Beginnirig from the Paffage 
of the Sun's Centre over the Meridian of any Place j and had 
tlie Sun no Motion in the Ecliptic, or was his Motion reduced 
to the Equator or iu right AfcenJion uniform, he wogld always 
return to the Meridian after equal Intervals of Time, Bot his, 
apparent MotFcn in the Ecliptic being continuuJIy varying, 
and his Motion in right Afceation being rendered further un- 
equal on Account of the Obliquity ot the Ecliptic to the 
Equator, from thefc Caufes it arifca that tlie Intervals of his 
Return to tlie Meritiian become unei]ual, and the Sun will gra» 
dually come too ilaw or too foon to tlie Meridian for an 
eqouble Motion, fw:li as that of Clocks and Watches ought 
to be. 

Tliis Retardation or Acceleration cf the Sun's coming t« 
the Meridian is called the Equation of Time, and is contained 
in the latl Column but One of Page zd ; and when applied 
according to its Tirtc to the Apparent Time, or that deduced 
immediately from the Sun, gives the me^n or equated Time, 
ivhtMice the Error of a Clock or Watch may be found, 
and, if required, it may be corrcftcd. 

If it is propofed to convert mean Time into apparent, 
this is done by a contrary Procefs, by applyi' g the Equatioi) 
ef Time to the mean Time given, with its Title or Sigr» 
changed ; viz. fubllrading inltead of adding, aivd adding in» 
itead of fubflrafting. 

The Equation of Time being fet down in the Ephemerls 
for the Noon at Greenwicli, Pro^wrtion muft be irade accord- 
ing to the daily Ditfcrence, lo find what it fliould be at my 
given Time reduced t« the fame Meridian, as in the preced-

As often at It may be required to make any Calcubtioirt 
torn aflronomJcal Tables, and the Time given be apfxirciit 
Tiine; it is recdlary firft to apply the Equation of Tim* 
thereto to convert it into mean Time, the Tables being dif- 
pofed according to mean Motions. Thus the Articles con- 
Zaliied h\ tlie Ephemerls anfwering to Noon were ccm,julei 
too**, increafed, or 24 Hours diminished, ly the Equation of 1 
'i'ime: And tlie Moon's Places fet down for Midiiight were 
computed to iz\ increafed or diininilhcd by tlic Equation oi\ 
Time. 

^\^lat has been Ihewn concerning the Equation of Timd 
shiefly rcfpedls the Aftronomer, the Mariner Iiavin^ litirle , 
to de with it in computing his Longitude from tlie Mocn'* 
Diftances from the Sun and Stars obfcrved at Sea with tlia 
Help of the Ephemerls, all tlie Calculations thereof being ad- 
apted to apparent Time, the fame wliich he will obtain by 
Die Altitudes of tlie Sun or Stars in the Manner hereaflar 
prcfcribed. 

But if Watcjjes made upon Mr. John Harrifon's or other 
equivalent Priociples (hould be brnuglvt into L'fc at Sea, the 
apparent Time deduced from an Altitude of the Sun niuft ie 
correfted by the Equation ©f Time, and tlic mean Time 
found compared witli tliat Ihewn by the Watch, the Diife- 
lence will be the Lonqitude iji Tuna from the Meriditm by 
wliich the Watcli was fct ; as near as the Going of the Watch 
«aa be depended upon. 

The Equation of Time was computed for the Epliemeris of 
1767 from the Table, P.igc 3d of M.-ij'cr's Tabks ; but Ha 
Account of that Table beiiv made only to the neareft Second 
williout Decimals, and the Neglei^t of the fnwU Equations of 
the Sun, tiie Calculations of tliat Article in the Year 1 767, 
cannot always be depended upon nearer than Two Secoudjg. 
For the Year 17GS and the following Years it will be com- 
puted in the llrift Manner explained in my Remarks upo« 
that Subjefl, in the Philof. Tranlad. Vol, liv. P. ^4.2 for the 
Year 1764 ; namely, by taking the Difference of the Sun's 
true right Afcenlion, and his mean L/^ngttude correrted by 
tlie Equation of the Equinoxes in right Afcenfion, and turri- 
ing it into Time at the Rate of 1'. to i^'. tSV. The Equa- 
tion of Time will be additive or fubftrnftive as the Sun s true 
riglit Afcenliun is greater or Icfs tlian his mean Longitude. 

The Semidianitter of ilie Sun, Page 3d, is nccelfary to re- 
duce the •bfervcd Altitude of his upper or lower Limb to that

•f the Centre ; alf(? to reduce the obferved DIftance of,^| 
Moon's near-eft Limb trcm the Sun's neareft Limb to the Dii 
tance of the Centres. It is alfo ufeful to AftronoiTiers t« 
verify or afcertain the Exaftnefs of tlie Scale of flieir Micro- 
meters, by Compariibii vvitli the Meafure of the Sun's hori- 
zontal Diameter. Tliis Pradlicc is particularly ufeful in £r>lat 
Eclipfcsi, when the Diftance of the Cufjw or the Verfe Sine 
of the vnieclipfed Part has been jneafured with the Micro- 
meter. Tlie Semidiameters of tlie Sun in Mayer's Tables, on 
wliich all the Calculations refpefting the Suti and Moon arC 
made, fuppofc the Semidiameter at the mean Diflancc to bft 
i6',2">8. which Mr. Mayer fays he deduced from above 130 
Obfervations taken with his Six Foot mural Quadrant, which 
feemed to him not ill adapted to the Pufpofe. It iliay not 
be amifs to take this Opportunity to remark that the Qua- 
drant here mentioned was given to the Univerfity of Gottin- 1 
gen by his late M^iefty, and was made by Mr, J-ohn Bird aftetf 1 
tlie Model of the Eight Foot mural Arda, which he finifhed 
for the Rcyal Obfervatory at Greenwich, and put up tliere in 
the Year 1750. Mr. Mayer made his Obfervations with his 
Six Foot mural Arch, from the Year 1756, to the Time of 
hisDeceafe; with it he fettled the mean Obliquity of the 
Ecliptic to the Beginiiinn; of the Year 1756, at 23*, 28'. 16''. 
which Dr. Bradley fettled by his Obfervations made in the 
Years 1750 and 1751, at 23°.28'. i8'^ The Difference is 
agreeable to what ought tn atife from the gradual DiraiHution 
of the Obliquity of the Ecliptic at the Rate ©f about a a Se-' 
coiid in a Year. The fame Irillruiiient he alfo ufed in fettling 
the Elements of his folar Tables ; and it is moft probable that 
with the fame he fettled ]ii> Table of Refra^ioas at the End 
of his folar Tabic? ; the Agreement of this Table with Dr. 
Bradley's, fee Page 2d of requilltc Tables, (being bothfuited 
to tlic f^mc Temperature of tlicAir)is fo great, llitt they feein 
rather like One aud the fame than Two different Tables. 

The Time of the Sun's Semidiameter pafliiig the Meridian, 
ferves to reduce anObfervation of a Tranfit of the preceding or 
fubfequent Limb over the Meridian to tliat of the Centre, when 
only One was obferved. It fignifies a Portion of apparent Time, 
or even mean Time, the Difference being abfolutcly infenfible 
upon fo fmall an Iiiten'al. It is foDiid thus : Increafe the Sun's Se- 
midiameter in the Ratio of the Cofine of his Declination te the 
Radius, tofind his Semidianaeter in riglitAfcen(ion,which turned 



into Tij^e at the Rate of i'. to i; 



and 1". te 15". gives the 
Time 



[ I5J ] 

red. The Sun's Semidiameter in right Afdenfioii 
is readily found by adding the Log. Cofinc of his Declina- 
tion to the logidic Logaritlini of his Semidiameter, the Sum 
is the logiftic Logaritlun of his Semidiameter in right Afcen- 
fion ; which divided by J j gives the Time of liis Semidiameter 
pafTmg the Meridian. If the Clock by wliich the Obfervation 
is made be regulated according to fidereal Time, this Quantity 
muft be ijicreafed in tiie Ratio of 36J to 366, if great Preci- 
(ion is required. 

From the Time of the Sun's Semidiameter pafling the Meri- 
dian may be alfo found the Time of its paJTuig the horizontal 
or vertical Wire of a Quadrant or Sextant, vvliicli on fonie 
Occafions may have its life, — The hourly Motion of the 
Sun is nfeful in amipiiting folar and lunar Eclipfes ; alfo ia 
correcting the alFumed Longitude of »he Ship, in order to 
find the Time from an Obfervation of the Diflance of tlie 
Moon from the Sun, independant of the Diftances contained 
in the nautical Ephemeris; See Britilli Mariner's Guide, Page 
49, and Table at the End of the fame. Page ij, which is 
sdib copied at Page 14 of requifite Tables. Tlie Logarithm 
of the Sun's Difiance is ufeful in tlie Calculation of the 
Places of the Planets and Comets. The Place of tlie Moon's 
Node fignifics its mean Longitude, and is neceflaiy for find- 
ing the Equation of the cquinodlial Points both in Longitude 
and right Afcenlion, tlic Equation of the Obliquity of the 
Ecliptic, and 'the Deviations of the fixed Stars in right Af- 
cenfion and Declinatian. 

The Eclipfes of Jupiter's Satellites are well known to afford 
the readtdl, and for gejieral Prailice tlie belt Method of 
fettling the Longitudes of Places at Land ; and it is by their 
Means principally that Geography has been fo much reformed 
within a Century'yait, and tlie Pofition of the moft dilTant 
Places determined to equal Accuracy with the neareft. It was 
hoped that fonie Means might be found of ufing proper Tele- 
fcopes on Shipboard to oblerve thcfe Eclipfes, and could tliis 
be eft'efted, it would be of great Service in afcertaining the 
Longitude of a Ship from Time to Time. In my Voyage to 
Barbadoes under the Direftion of the Commiflioners of Loiir 
gitude, 1 made a full Trial of the late Mr. Irwin's Marine 
Chair propofed for this Purpofe, but found it totally imprso' 
ticabk to derive aj\y Advantage from the Ufe of it ; and,

Irrtfafzritlds of the Moiion of a Ship, 1 am afraid the 
complete Management of a Telefc<>pe on Skipboard will al- 
ways remain among the Defiderata. However, I WoUld not 
be underftood to mean to difcourage anv Attempt founded 
■Bpon good Principles to get over this Drtficulty, 

The Telefcopes j-»roper for obferving the Eclipfes oTJupF* 
ter's Satellircs, are common refrailtng Telefcopes, from ij to 
«o Feet, reflertirig TclefcojTes of i8 fjiclics or Two Feet, and 
Telefcopes of Mr. Dolloiid's ConftruiHon nith Two Objec> 
Glalfes from Five t<5 lo Feet ; or, which are ftill more con- 
venient, thofe of 3* Feet, which he has lately found a Method 
of conrtrurting Witli Three Objed Glaltes, which are as mana- 
geable as reHcfling TelcfcopC5, and perform as moch as thofe 
which he makes of lo Feet With Two Objeft Glaffes. 

The Eclipfes of Jupiter's Satellites are obferved by Aftrono- 
mere gt Land, as well in order to provide Materials for 
impronng tlic Tiieories and Tables of tlieif Motions, as £rvr 
the fake of Comparifon with the correfj^xntding Obferratiocw 
which may tie made by Perfons hi diflerent Parts of the Globe, 
whercljy the Longitude of fuch Places Will be accurately af- 
certained. It is indeed to be lamented that P«rfons whovifit 
diftant Countries arc hot more diligent to muhiply Obfen'a* 
tiont of this Kind, for wanY of which, the Obfervalions made 
by Aftpoitomcrs on Shore lofe Half tl^ir Ufe^and the Improve- 
ment of Geography fcems to be at a Stand. But it is to be 
hoped that an Emulation will fpring up arftong thofe ivho 
may have Op|X)rtunities c'f rendering fo ufeful a Service to 
the Public, to incite them to watcli diligently fer the Occa- 
fions of obferving tiiefe Eclipfes carefully, partrcutoly of the 
Firft and Second, which are moft txztitor the Pcrpofe. The 
Eclipfes carefully cilculated and fet doavnfin tlie Ephcmeris, 
will fcrve to advertifc ihem and ObfervCTWn general of the

Perfon who Ihall l>e under amy Meridian different from Green- 
wich, mutl turn liis Dirterence of Longitude into Time : Sec

by Reflexion from a Bafon of Water or Qiiickfilver, or fronv ] 
the Horizon of the Sea, if the Obfervcr has an open Profjnjtila 
and is not elevated above j or 600 Feet aix)ve the Level of | 
tlie Sea. But, if Opportunity doesiwt admit of taking equal 
Altitudes, the Time may be determiaied from One Altitude ] 
taken jn any of the Metliods above mentioned, at leaft TwqJ 
or Three Points of the Compafs diflanl from the Meridian, 
but the nearer to the Eaft or Weft the better, tlie Latitude 
of the Place being knnun, or being found by Obfervations 
of the Meridian Altitude of the Sun or Stars made on Purpofc. 
It will be better to take feveral Altitudes irt order to take a 
Mean of the Refults for greater Certainty. The Manner of 
computing the apparent 'rime from tl)e Altitude of the Snn 
or a Star, will be obfcrved when we come to treat of the 
Method jof rttiding the Longitude by tiie Obfervations of the 
Dilt^nce of the Moon from the Sun and Stars by tlie Help of 
the Ephemciis. 

The Obfen'er being in a Place vhofe Longitude is well 
known, Ihonld be fettled at his Telefcope Three Minutes be- 
fore the expected Time of an Immcrfion of the firft Satellite} 
Six or Eight Minutes before tiiat of tlie fecond and third Sa- 
tellites; and a Qnarter of an Hour or more before that of the 
fourth Satellite; chiefly on Account of the Uncertainty (rf their 
Theories; but, if the Longitude of the Place is very unccf' 
rain, lie muft begin to look out for the Eclipfc proportion^ 
abJy fooner: Thus if tlie Longitude of the Place is uncertain 
to 30 Degrees, aiifwering to 12 Minutes of Time, he ought 
to fix himfelf tohts Tcleicope iz Minutes fooner than is men^ 
tioned above. Neverthclefs when be lias obferved One Ec- 
lipfc of any Satellite, and thereby found the Error of the 
Tables, he may allow tlie fame Correilfon to the Calcula- 
tions a^ the Ephemeris for fcveral Months, which willadver- 
tife him very nearly of the Time of expefting the Exlipfes of 
the fame Sjitellite, and difpenfe with his attending fo long.

»ut of the fame. Tliey generally happen when the Satcf- 
lite is at fame DiiVjnce from tlie Body of Jupiter, except 
near the Oppofition of Jupiter to the Snn, when the Satel- 
lite approaches nearer to his Body, Before the Opp<.ilition of 
Jupiter to the Sun the Immerfions and Emerfions happen 
on the Weft Side of Jupiter, ajid after the Oppofition on the 
Eall Side ; but if an aftronomical Telcfcope ti: ufed, which 
icverfes Objects, the Appearances will be direftly the con- 
trary. Before the Oppofition, the Immerfions only of the 
firft Satellite arc vifible; and after the Oppofition, the Emer- 
sions only. The fame is generally the Cafe with refpcft to 
the fecond Satelliie; both the Phenomena of the fameEclipfe 
are frequently obferveable in the Two outer Satellites. The 
Immerfions and Emerfions marked with an Afteriflc in the ^ 
Ephcmeris are thofe vifible at Greenwich. 

To know if an Eclipfe will be vifiblc in any Place, find if 
Jupiter is 8»,or io°. above the Horizon of the Place, and the 
Sun as much belcw it. This may be done near enough by a 
celeftial Globe : Otl\erwife, the Time of the Sun's Rihii^ and 
Setting niay be found for any Latitude by a Table offcmi- 
diurnal Arcs, contained in the jTopulsr Book called the Ma- 
riner's Compafs Re£lilied, and many other Books; the Time 
of Jupiter's Rifing and Setting may alfo be found from the 
Time of his palTmg the Meridian and Declination fet down 
in the P.phemcris, with the Help of the fame Table of femi- 
diiimal Arcs; adding or fubftrafting the femidiunial Arc 
anfwering to tiie fame Declination of the Sun ; Remembering 
always tliat if Jupiter's Declinatipn and the Latitude of the 
Place are of the fame Denomination, the femidiumal Arc 
will be more than Six Hours, and if they are of contrary DC' 
nominations, it will be Icfs than Six Hours. 

The Immerfion or Emerfion of any Satellite being carefully 
plferved in any Plice acrordinp to apparent Time, the Lon- 

fitudc from Greenwich is found immediately by taking the 
difference of the Obfcr\'^ation from tlse correfponding Time 
fhewn in the Ephcmeris, which mull be turned into Degrees, 
IS'c. by Table Page 6, 7, and 8 ; and will be Kift or Weft ol 
Greenwich, .w the Time obferved is more or lefs than that 
of the Ephcmeris.

pofed to be observed at the Cape is more than tliat of ri

It may not be ufelefs here to oWerve that the Longitude 
of the Cape of Good Hope i\ 13'. sj^rziS". 23'. i^". fet 
down in the Biitii}i Mariner's Guide, is that of the Town; llie 
Latitiule alfo belongs to the fame ; being both determined 
from the Obfcrvatioas of Meffrs. Mafon and Dixon, who went 
thither under the Direftionof the Royal Society, and obfervcd 
theTranlit of \'enas in the Year 1761. Hence, by the Help of 
llie Charts, I find the Longitude of the Cape Point or Pro- 
montory iS''. 45'. Eift of Greenwich, and its Latitude 
34*. 30'. S. the Longitude of Cape Falfo, i9<'. 15' E. and irs 
Latitude 34''. 34' S. If ihefe Determinations of the Situa- 
tions of the Cape Point and Cape Falfo are in any refjieft 
uncertain, it arifes from the Impcrfedion of tlie Charts I 
was obliged to make ufe of, in reducing the Longitjide and 
Latitude from theCajje Town to the Two mentioned Points: 
For from the near Agreement of the AbbeedelaCaille'sObfer- 
vations with thofecf MclTirs. Mafon and Dixon, it is probable 
that the Situation of few Places is better determined than that 
of the Cape Town r But if any one has PolTeJTion of any 
Manufcript or printed Charts of thefe Parts that lie thinks 
may be depended upon, or has any Opportunity of deler- 
mining tl\e Points in Queftion relatively to each other from 
the Comparifon of feveral Journals of Shi}^, he may perhaps 
fix thefe Places with more Certainty than is here pretended 
to. 

It is to be obfen'ed that a correfpondenl Obf^rvalion of an 
Eclipfe of a Satellite of Jupiter, made under a ivell known 
Meridian, is to be preferred to the Calculations of the Ephe- 
meris for comparing with an Obfervation made in a Meridian 
whofe Longitude is required; but if no correfjxmding Obfer- 
vation can be obPsiiied, as is frequently the Cafe, it will be 
beft to find what Correflion the Calculations of the Ephe- 
meris require by the neareit Obfervatious to the given Time 
that can be obtained ; which CnrrecfYioii applied to the Cal- 
culation of the given Eclipfe in the Ephemeris, renders it 
almoft equivalent to an adlual Obfervation.

Remarks on fome Circumftanccs neceflary to be attended 
to, in order to obtain and apply t l»e Corredion of fecoud Dif- 
ference? rightly in computing the Moon's Latitude. 

I. If the Moon's Lititiidc taken out of the Ephemeris for 
^oon and Midn ght changes its ] denomination from North to 
South or from South to North, the Sum of tiie Two Latitudes 
of contrary Denominations, where the Change happens, is to 
tc accounted the firlt DirtcTCiice in that Place. 

II. If the Three fi\i\ Ditterences Jirft incrcafe and then de- 
crcafe, or viceverfa, lirft dccrcafe and then increafe. Half the 
Dillerencc of the Two fccond Differences is to te taken fox 
the menn fecond Diff<?rence. 

III. If the Scries of Four Latltnde; taken out fhould firft in- 
creafe and then decreafe about the Moon's greateft Latitudes, 
take the Sum of the Tvv o firft Differences ihinding on cacli 
Side of tlic grcaleit Latitude for the fcccnd Difference in that 
Place ; correct ihe Moon's Latitude at Noon or Midnight by the 
Itmple proportional Part firft found; and to tlie Latitude fo 
corre<!tcd, add always in this Cafe the Corredion froni Table 
Pnge 1 1 , anfwering to the Mean of the Two fccond Dif. 
ierences. 

Before 1 quit this Subjcft cf Interpolation by fecond Dif- 
ferences, I IJiall point out another Method, by which the 
fame End may be cbtai«»cd more readily, and with fewer 
R Jes, by thofe who are well acquainted with algebraical Sub- 
llra^ftion and Addition, and tlie M;umer of applying tiie Signs 
in thofe Operations. Subllrad each Latitude from the fol- 
lowing for the firft Differences, fo which prefix the Sign — if 
t «e Latitudes decreafe ; and fybftraft eacii firft Difference, 
thus found, from tiie fnllmviug one of the fame Order for the 
fircoRd Differences^ Half the Sum of ibe Two fecond Dif- 
ferences 



[ '«J ] 

fereiioes ftandlnjr on each Side of the Inter>'al to be interpo- 
lated^ is to be accounted the meaa fecond Ditfcrencc ; the 
€orre<flion corrcfponding to it by Table Page ii, is to be 
applied always witir the contrary ^ign. 

Thd"c Operations are to be performed, and the Signs to be 
applied as in algebraic Siibftraftion and Addition, Note 
further, if the Four given L;it"itiidcs change their Denoinina- 
jLion, call the fecond Latitude-^, aiid titofc of a contrary Dc' 
nomination — . 

The Moon's Declination may be found at any Houx in the 
fame Manner as her Latitude; but as the Correftion arifirg 
fron\ fecond Diifercnces will never exceed 2 J', thk may be 
neglefted on moft Occafions : bi;t if any one is deJirous to ob- 
tain the Declination true to a Minute, the Correiflion iiealily 
applied, as fliewn above. 

The oilier Articles of Page 7, and 8, viz. tlve Moon's right 
Afcenfion, her Scmidiameter, horizontal Parallax, with its 
Logiirilhm, and the Dillances contaijicd in the Four laft Pages 
of the Month, may be all found correctly by even Propor- 
tion, without requiiing any Allowance on Acco^int of fecond 
Ditlerenccs, The proportional Part of the Moon's Longitude, 
i^c. for any Hour, ni:iy be found very readily by the Help of 
the Table of proportional Logarithms at the End of tivt requiiirc 
Tables : F«r wliich confult the Explanation of thofc Tables. 

The Moon's Longitude and Litilude are ufed in compviring 
her Diftances from the Sun and Stars cont.iincd in the Four lau 
Pages of the Month, as well as in the Appulfes to Stars pointed 
out in Page l, and, jointly with her Parallax and Scmidia-

and Moon, ami the Occultations of fixed Slrars and Planet* by

-more convenient to fubllittilt proportional Logarithms of the 
Moon's Parallax inllead of the logiftic Logarithms in a fu-

compute her Altitude at any Time, particiilaily at the Ob- 

• fcrvation of lier Diftancc from the Snn or a Star, fiippofing it 
was lieglected to be or cculd not be obferved properly ; which 
Jatter Cafe may fomelijiics happen in tlie Night, though I 
Ihink but rarely ; the utmoft Accuracy nat being required 
for the Calculations of Refrndlion and Parallax. See Britifli

Seniidiameter and Parallax, ferve for tijidir.g' tl^e Latitude by

Time from lier'Altitude obferved at the Obfervaticn of her 
Diftance from a Star; wiitnce the Longitude may be inferred,

The Difbncea of tlie Moon from the Sun and fixed Stars, 
contained in tiie kow hA Pages of the Mo;ith, arc fet down 
to every Tiircc Hour> of App;irciit Time by tlie Meridian 
of Greenwich, and are deligned to relieve the Mariner from 
tlie NccefTity of a Calcubtion, which lie miglit think proJix 
and troubleforne, and to enable him, when compared with 
llie fame DiJJances oL4erved carefully at Sea, to ijifer his Lon- 
gitude readily ;uid with little Danger oi Milbike to a De- 
gree of Exactnefs that may be tiiought fufficieijt for moft 
I'.autic^il Purjxvfc% But ufcful and valuable as tlie Praftice 
ct this Miethod may be at prcfcnt, it is a Remark not un- 
worthy oitr Notice, that there is Room to hope, by future Im- 
provements of tl'.e lunar Tables, and tlie Introdurtiun of 
a more accurate Metiiod of conftnifting Inikument?, it may 

^^ carried to a much higher Degree of Perfection. 

The Mooii's Diflance are computed both from the Sun 
and prop^^r Stars, and generally from One Objeft on each 
Side of licr, to afford the Mariner a greater Number of 

i,. Opponvmities cf Obfervation, and a Means of attaining a 
greater Pegrce of Exaitnefs. The Diftances from tlvc Siii> 



are computed birtween 40* andj2C|"' of Dlftance, Wh3e 
the Moon is between the Diftanccs of 20° and 40' from the 
Sun, her DIftance is computed oiJy from a Star on the con- 
trary Side that the Sun is. When (he is between the Dif- 
tanccs of 40" and 90" from the Sun, her Diftance is com- 
puted both from the Sua and froii a Star on the ccntraiy 
Side to the Sun ; when the Moon is above 90° from the Suu 
her Diftance is computed from Two Stars, one on each Side 
of her ; thongh ftill her DliVance is computed alfo from the 
S'.tn from go"* to 120°. Though the Difbtnce of the Moon 
from the S«n or Star, well obfcrved with a good Inftmment, 
isfufficient to determine the Longitude, with the Help of the 
Ephemeris, always within a Degree, and generally much 
nearer, yet it will conduce to fiiU greater Accuracy, if tiie 
Obferver takes the Difllance of the Moon from Two Stars, or 
tlie Sjn and a Star, or, when the Moon is between 90 and 
1209 DiJbncefrom the Sun, from the Sun and Two Stars, if 
Jie c&n be fo lucky as to obtain thefe fcveral Obfervations. 

Tlie Longitude being computed from the Obfervations 
made witli each Star refpefttvely, the Mean of the Refults 
is to be taken as probabJy approaching^ nearcii to ihe true 
Ijjngitude. In particular the Moon's Diftance fhoiild be taken 
from Two Stars, or the SuiV and a Star on each Side of her, as 
often as Opportunity permits, fmce the Mean of the Refults will 
probably be at leaft asexail agam as cither fcparately, 1 mean 
as far as depends on any Imperfedlion of the Initrumcnts, 
and unavoidable fmall Errors arifiHg in the Ufe of them ; Er- 
rors of thefe Kinds having a natural tendency to corrcift eacli 
other ; for that fmall Error which arifes from the lunar 
Tables will affed the Refult from either Star equally. But tlie 
Error of Mr. Mayer's laft lunar Tables liere made ufe of, fcarce 
ever exceeding 1' at the moft, and feldom amounting to 20". 
llic Uncertainty hence ariJing in the Determination of the Lon- 
gitude can fcarcely exceed lialf a Degree, and generally will 
not exceed 10 Miles. 

The Diftances fet down in the Ephemeris, afford the Ob- 
fer\-er a ready Means of knowing the Star from xvliich the 
Moon's Diftance is to be obferved ; for he has notliing to 
do but to fet his Quadrant to the Diftance computed roughly 
from the Ephemeris, negleftiiig the Seconds, at the apparent 
Time ellimatcd nearly by the Meridian of Greenwich ; and 
dired his Sight tc the Eaft or Well of the Moon, accord- 
ing as Uie Diftance at Greenwich is found in Page 9 and

inilUkiJig another for it, if the preceding Direflions are

nearly by turning the fupjwfed Longittide from Greenwich 
into Time, by Table Page 6, 7, and 8, and adding it to or 
CuMrading it from the Apparent Time at the Ship, as its Lon- 
gitude is \\'cR or E-^ll of f-Jre«midj. It will he fiifficient if
