respecting the Water it contains , &c. 3 6 9 
their course, and for the last nine inches the membrane has 
a villous appearance, as in the human stomach. Close to the 
pylorus there is a glandular substance of a conical form, which 
projects into the cavity ; the blunt end of it resting upon the 
orifice of the pylorus. This is similar to what is met with in 
the bullock, but still more conspicuous. 
The fourth stomach of the camel corresponds with that of 
the bullock in all the general characters, and resembles it in 
most particulars. It exceeds it in length, but the plicae are 
so much smaller, that the extent of the internal surface must 
be very nearly the same in both. It differs from it in having 
a contraction in a transverse direction immediately below the 
termination of the plicated part, which has led both Dauben- 
ton and Cuvier to consider these two portions as separate 
cavities. I should have been induced to adopt this opinion, 
were it not for the circumstance of their internal structure 
being the same as that of the bullock, which must be ad- 
mitted to be only one cavity, and as the uses of these cor- 
responding structures must be similar, the analogy between 
the two is better kept up by considering it in both animals as 
one cavity, only remarking the contraction in that of the 
camel as a peculiarity belonging to ruminants without horns. 
From the comparative view which has been taken of the 
stomachs of the bullock and camel, it appears that in the bul- 
lock there are three stomachs formed for the preparation of 
the food, and one for its digestion. In the camel there is one 
stomach fitted to answer the purposes of two of the bullock, 
a second employed as a reservoir for water, having nothing 
to do with the preparation of the food ; a third so small and
