The stomach of the pig is simple, although it 
takes on somewhat of a compound form, and to a 
certain extent performs the function of carnivora 
and ruminants. It consists of two portions: car- 
diac and pyloric; the latter is the smaller, but the 
divisions are marked externally by a much more 
distinct contraction. At the upper and left portion 
of the cardiac half is a small cul-de-sac. The 
oesophagus is infundibuliform in its termination. 
The mucous membrane, for the most part villous 
(velvety) in its structure, forms two folds, which 
extend from the cardiac towards the pyloric ori- 
fice, representing undeveloped oesophageal pil- 
lars and canal. The gastric juice of the hog con- 
tains the same ferments as are found in the secre- 
tions of other mammals. The secretions from dif- 
ferent portions of the stomach differ; that obtained 
from the greater curvature contains more mucin,’ 
more acid and more ferment than that from the
