ture on the inner side of the cheek, opposite the 

 second upper premolar tooth. 



b. The infra-orbital gland is an irregular lobulated 



mass, about three-quarters of an inch long, lying 

 below and in front of the eye, partly above the 

 zygomatic arch and partly hidden by it. 



The duct runs downwards to open into the 

 mouth, close to the Stenonian duct. 



c. The submaxillary gland is a compact, reddish, 



ovoidal mass, lying close to its fellow between 

 the angles of the mandible, and in front of the 

 larynx. 



The duct, Wharton's duct, leaves the outer 

 side of the gland near its hinder end, and runs 

 forwards along the inner side of the jaw to open 

 into the floor of the mouth, midway between the 

 lower incisors and the root of the tongue, the 

 openings of the ducts of the two sides being about 

 an eighth of an inch apart. 



Dissect from the ventral surface. To follow the chcct into 

 the mouth, turn the halves of the lower jaw aside. 



d. The sublingual gland is an elongated, flattened, 



reddish body, about three-quarters of an inch 

 long, lying along the inner side of the ramus of 

 the mandible, between this and Wharton's duct. 



The ducts open separately on the floor of the 

 mouth. 



III. THE ABDOMINAL VISCEEA. 



Bemove the skin from the trunk and limbs. Lay the 

 rabbit on its back, and fasten it down to the dissecting-board 

 by pins through the limbs. 



[A. The mammary glands in the female lie immediately 

 beneath the skin. They are yellowish, fatty-looking, dendri-
