a pure state into the second stomach, that part of it is re- 
tained there, and the rest runs over into the cellular structure 
of the first, acquiring a yellow colour in its course. 
This confirms the account given by M. Buffon in his exa- 
mination of the camel’s stomach, as well as that of other 
travellers, who state that when a camel dies in the desart, 
they open the stomach, and take out the water, which is con- 
tained in it, to quench their thirst. 
That the second stomach in the camel contained water, 
had been generally asserted, but by what means the water 
was kept separate from the food had never been explained, 
nor had any other part been discovered, by which the com- 
mon offices of a second stomach could be performed. On 
these grounds Mr. Hunter did not give credit to the assertion, 
but considered the second stomach of the camel to correspond 
in its use with that of other ruminants, as appears from his 
observations on this subject stated by Dr. Russell, in his 
history of Aleppo. 
The difference of opinion on this subject led me to exa- 
mine accurately the structure of the stomachs of the camel, 
and of those ruminants which have horns, so as to determine, 
if possible, the peculiar offices belonging to their different 
cavities. 
The most satisfactory mode of communicating the result of 
this inquiry will be first to describe the different stomachs of the 
bullock, and then those of the camel, and afterwards to point 
out the peculiarities, by which this animal is enabled to go a 
longer time without drink than others, and thereby fitted to 
live in those sandy desarts of which it is the natural inhabitant. 
The relative position of the parts is described while the animal
