front of the eye; the submaxillary lies between the angles 
of the mandible ; the small sublinguals lie along the inner 
side of each ramus of the mandible. 
The pharynx passes into the gullet, and that leads through 
the diaphragm to the expanded stoinach, which is dilated 
at its upper or cardiac end, and narrows to the curved 
pyloric end. Partly covering the stomach is the large liver. - 
The first. portion of the intestine, which is called the 
duodenum, receives the bile duct, and has the pancreas in 
its folds. Then follows the much-coiled small intestine, 
measuring many feet in length. It should be noted that, in 
adaptation to the more slowly digestible food and the larger 
amount of indigestible residue, 
the intestine of herbivorous 
mammals is relatively longer 
than that of carnivorous types. 
The lower end of the small 
intestine is expanded into a 
sacculus rotundus. Here the 
large ceecum—a blind diverti- 
culum—is given off; it ends 
in a finger-like vermiform ap- 
pendix. Its proximal end is 
continuous with the colon or . os

first part of the large intestine, rotundus; co/., sacculated colon ; 
the beginning of which is much {> ,cipeums a vermiform 
sacculated. The large intestine 
narrows into the long rectum, in which lie little feecal 
pellets. On the last two inches of the rectum there are 
paired yellowish glands. Beside the anus are two bare 
patches of skin, with the openings of the ducts of the 
perineal glands, whose secretion has a characteristic and 
strong odour. 
The liver is attached to the diaphragm by a fold of peri- 
toneum—the glistening membrane which lines the abdomi- 
nal cavity. In the liver there are five lobes. From these 
lobes the bile is collected by hepatic ducts into a common 
bile duct, which is also connected to the gall-bladder by the 
cystic duct. 
The very diffuse pancreas lies in the mesentery of 
the duodenal loop. Its secretion is gathered by several
