larger and longer than in the ox. Its capacity is about twice that of the 
‘reticulum and averages about two quarts (ca. 1.75 to 2 liters). The blind 
anterior end lies almost centrally in the xiphoid region, in relation to the liver and 
reticulum. Its body extends backward a little ventral to and almost parallel 
with the right costal arch. The pylorus is usually opposite the ventral end 
of the eleventh or twelfth intercostal space. At the reticulo-omasal open- 
ing and on the adjacent part of the laminze of the omasum are large, pointed, 
horny papille. 
The general arrangement of the intestine is like that of the ox. The small

intestine is about 80 feet (ca. 24 to 25 m.) long; its average diameter is about an 
inch (ca. 2 to 3 em.), the caliber increasing in its terminal part, where a very extensive 
Peyer’s patch is found. Duodenal glands occur for a distance of two feet or more 
(ca. 60-70 cm.) beyond the pylorus. The cecum is about 10 inches (ca. 25 em.) 
long, 2 inches (ca. 5 em.) wide, and has a capacity of about a quart (ca. 1 liter); 
only about two inches (ca. 5 em.) of it is free. The colon is about 15 feet (ca. 4 to 
5m.) long. Its caliber is at first about the same as that of the cecum, but dimin- 
ishes to about the width of the small intestine. 
The liver weighs about 20 to 25 ounces (ca. 550 to 700 gm.). It lies entirely
