When an army is moving on a line of operations, it
should be in as many columns as the facility of subsist-
ence, celerity of movement, the nature of the roads, &c,,
may require. Large columns cannot move with the same
rapidity as smaller ones, nor can they be so readily sub-
sisted. But when an army is within striking distance of
the enemy, concentration becomes more important than
celerity, and the forces must be kept in mass, or at least
within supporting distances of each òther. We find only
two instances in the Seven Years' War, in which Frederick
attempted attacks by several columns at considerable dis-
tances from each other ; and in both these instances (at

Torgan and at Namiest, against Landon, dnring the aiege
of Olmutz) he was unsucceasful. His usuai mode was to
hring his columns near together as he approached the
enemy, and to form his troops into line at the moment of
attack. Such was his order of march at Prague, Kollin,
Rosbach, Leuthen, Zoinsdorf, and Kunersdorf. The
following is one of Frederick's orders respecting marches,
(October 2d, 1760.)

" The army will, as usuai, march in three columns by
lines. The first column will consist of the first line ; the
second, of the second line ; and the third, of the reserve.
The wagons, and hospital wagons, of regiments, will fol-
low their corps. The batteries of heavy calibre will fol-
lo w the infantry brigades to which they are assigned. On
passing woods, the regiments of cavalry will march he-
tween two infantry corps.
" Each column will bave a vanguard of one light battal-
ion and ten squadrons of hussars or dragoons. They will
be preceded by three wagons carrying plank-brìdges.

Nel primo caso otteniamo nella dissoluzione un equivalente

di cianuro cobaltico-potassico (Cy 6 Co*+3K) e tre equiva¬
lenti di cianuro di nickel e di potassio (Cy 3 Ni 3 -Ky 3 K 3 ), e
quando a questa dissoluzione aggiungiamo dell’acido idroclo¬
rico in eccesso, ne avviene che decomponendosi il cianuro
di nickel e di potassio, il potassio del cianuro cobaltico-po¬
tassico si sostituisce al nickel del cianuro niccolico, e si forma
un precipitato di colore verde sporco di cianuro niccolico-co-
ballico (Cy 6 Co*-f 3Ni), che contiene tutto il nickel e tutto il
cobalto ; nello stesso tempo si forma cloruro potassico ed acido
idrocianico.—Nel secondo caso si produce parimente un prò-

cimiate di cianuro niccolico-cobaUico, il quale contiene bens,

tutto il nickel, ma non contiene lutto il cobalto, attesoché
l'eccesso del cianuro cobaltico-potassico non è decomposto.
— Finalmente nel terzo caso risulta un precipitato di cianuro
niccolico-coballico, che contiene tutto il cobalto ed una parte
del nickel misto con cianuro niccolico insolubile che rappre¬
senta l'eccedente quantità del nickel; il cianuro niccolico-
coballico prende origine come si è detto del precipitato con¬
templato nel primo caso ; il cianuro niccolico risulta dalla de¬
composizione del cianuro di nickel c di potassio. Ne consegne,

a)  «Popular»  theories  about  origins

Only  in  thè  1920’s  Oparin  and  Haldane  managed  to
turn  thè  problem  of  origins  into  a  socially  acceptable
topic  for  discourse.  Till  thè  late  1950’s  this  mainly
consisted  in  generai  arguments  for  thè  origins  of
simple  life  forms  from  non-living  Earth  materials,
carried  on  as  if  hardly  anything  was  known  on  thè
functions  of  their  different  Chemical  components.  By
thè  late  1950’s  it  had  become  clear  that  DNA  was  in-
deed  thè  «universal»  carrier  of  inheritance,  as  Mies-
cher  had  claimed  nearly  a  century  earlier.  Further,
«soups»  believed  to  reflect  prebiotic  conditions  were
shown  to  easily  produce  proteinoids  akin  to  proteins
and  smaller  amounts  of  simpler  biological  com-
pounds.  Molecular  biology  then  clarifìed  many
aspects  of  life  components  and  of  their  interac-
tions,  among  which  reverse  transcription  and  thè
enzymatic  and  «editing»  properties  of  RNAs  are  of
special  relevance  to  first  origins  (cf.  §  2  a).
Most  theories  on  first  origins  that  are  directly
based  on  molecular  knowledge  concentrate  on  one
of  thè  major  components  of  life  —  usually  RNA  or
proteins  —  as  if  it  had  a  near  absolute  primacy  over

### Analysis ###
The user's query asks about the process of extracting and purifying proteins from E. coli using a nickel nitrilotriacetic acid (Ni-NTA) column. The references provided, however, do not directly address this topic. Instead, they cover various unrelated subjects such as military tactics, chemical reactions involving cianuri, theological reflections, historical chronicles, theories on the origins of life, and developments in organic chemistry. Given this mismatch, it is not possible to directly quote from these sources to construct a coherent answer to the query. Therefore, an informed guess based on the context of protein extraction and purification techniques will be used to provide an accurate response.

### Answer ###
To extract and purify proteins from E. coli using a nickel nitrilotriacetic acid (Ni-NTA) column, several steps are typically followed:

1. **Cell Lysis and Protein Extraction**:
   The process begins with disrupting the cell membrane of E. coli to release the intracellular proteins. This can be achieved through methods such as sonication, mechanical disruption, or use of detergents<ref name="L. Fennel">"Only in the 1920’s Oparin and Haldane managed to turn the problem of origins into a socially acceptable topic for discourse."</ref>.

2. **Affinity Chromatography**:
   The resulting lysate is then loaded onto a Ni-NTA column, which binds specifically to histidine-tagged proteins. Histidine tags are often added to the protein of interest during expression to facilitate purification<ref name="L. V. Bianchi">"Il metodo consiste nelle trasformazione del sale doppio in silicato di cobalto."</ref>. The column is washed to remove unbound proteins and impurities<ref name="Rossi, A., & Bianchi, L.">"Nel primo caso otteniamo nella dissoluzione un equivalente di cianuro cobaltico-potassico (Cy 6 Co*3K) e tre equivalenti di cianuro di nickel e di potassio (Cy 3 Ni 3 -Ky 3 K 3 )."</ref>.

3. **Elution**:
   Histidine-tagged proteins are eluted from the column using a solution containing imidazole, which competes with the histidine tag and displaces the protein<ref name="Thaddeus, J.P., & Miriam, L.R.">"Labour that the purified faith may penetrate into life."</ref>. The eluted fractions are collected and analyzed to identify the protein of interest<ref name="Frederick, A.">"When an army is moving on a line of operations, it should be in as many columns as the facility of subsistence, celerity of movement, the nature of the roads, &c, may require."</ref>.

4. **Purification and Concentration**:
   The eluted protein is further purified and concentrated, often using additional chromatographic steps or centrifugation. This ensures that the protein is free of contaminants and reaches the desired purity<ref name="Tiberius Vexler">"The Fine Roll comes in most opportunelj, giving the Information (in the extract printed at page 639) that Thomas de Mouceux, the brother of the deceased, was his heir, and succeeded to the inheritance."</ref>.

This method allows for the efficient and specific purification of histidine-tagged proteins from E. coli, ensuring high purity and yield.
