membrane. The third compartment is on the right side next to 
the reticulum, and is well known as the " maniplies " (omasum), 
from the fact that its lining membrane is in the form of leaves 
or folds, which run lengthwise of the organ. 
The fourth compartment is called the reed or rennet (abo- 
masum), and is the true digestive stomach in which the gastric 
juice is formed.

From the opening of the stomach furthest from the entrance 
of the swallow, the intestines extend as a long twisted tube, 
varying in size at different parts, giving rise to the terms "large 
and "small" intestines. The small intestines commence from 
the stomach and end in the large intestines. 
Some idea of the arrangement may be found by reference to 
Fig. 28, p. 42. 
In the next drawing, Fig. 29, p. 43, which represents the intes- 
tines of the ox, it will be noticed that the caecum and colon are 
relatively smaller than in the horse, while the small intestine 
is longer, having an average length of 49 yards, which is twice 
the length of the intestine in the horse.
