which, next the great end, is covered with a cuticle continued 
from the oesophagus, and extending further towards the pylo- 
rus on the small curvature than on the great one. The oeso- 
phagus enters obliquely ; which prevents regurgitation from 
readily taking place. At the great curvature, immediately 
beyond the termination of the cuticle, which forms a prominent 
ridge, there is a glandular structure of some extent : this is 
insensibly lost in the more membranous portion, which extends 
to the pylorus, and appears to be a villous surface subdivided 
into small portions of unequal size, giving it a tesselated 
appearance. 
When the horse’s stomach is procured in an empty state, or 
nearly so, immediately after death, and is inverted and gra- 
dually distended, it is found to consist of two very distinct 
portions, there being a muscular contraction between the cuti- 
cular portion and the other. 
No. IX. The Ass. 
The stomach of the ass resembles that of the horse in all 
respects, and being of a more delicate structure its minuter 
parts are more easily distinguished. A number of orifices of 
glands immediately beyond the cuticular portion on the upper 
curvature are distinctly seen, which I was unable to distinguish in 
the horse ; but there can be no doubt of their existence in that 
animal, although I was not so fortunate as to observe them.

No. X. The Kanguroo. 
The stomach of the kanguroo differs in many particulars 
from that of any other known animal, and bears a much 
greater resemblance to the human coecum and colon than to 
any stomach.
