360 Mr. Home's Observations on the Camel's Stomach 
anterior. On pressing on this part a fluctuation of its con- 
tents could be distinctly perceived. A trocar with the canula 
was plunged into the most prominent of the cells, and on 
withdrawing it there passed through the canula 120Z. of 
water of a yellow colour, but unmixed with any solid matter. 
This fact having been ascertained, the first stomach was laid 
open, on the left side, at a distance from the cellular structure, 
and the solid contents were all removed. While this was 
doing some water flowed out of the cells, and some out of 
the second stomach, but the greater part was retained. That 
in the second stomach was nearly pure : while the other was 
muddy, and of a yellow colour, tinged by the contents of 
the first stomach. On examining the cellular structure no 
part of the solid food had entered it, nor was there any in the 
second stomach : those cavities having their orifices so con- 
structed as to prevent the solid food from entering, even when 
empty. 
On measuring the capacities of these different reservoirs in 
the dead body, they were as follows : 
The anterior cells of the first stomach were capable of 
containing one quart of water, when poured into them. The 
posterior cells three quarts. One of the largest cells held two 
ounces and a half, and the second stomach four quarts. This, 
however, must be considered as much short of what those 
cavities can contain in the living animal, since there are large 
muscles covering the bottom of the cellular structure, to force 
out the water, which must have been contracted immediately 
after death and by that means had diminished the cavities. 
By this examination it was proved, in the most satisfactory 
manner, that the camel when it drinks, conducts the water in
