passes into the tongue the duct continues craniad close against 

 the oral mucosa and parallel to the mandibula. It is accom- 

 panied by the duct of the sublingual, which lies at first dorsad 

 of it and then mediad. It opens at the apex of the prominent 

 papilla which lies at the side of the middle line at the cranial 

 end of the floor of the mouth. 



3. The sublingual gland is elongated and conical in form, 

 with its base against the submaxillary, of which it appears to 

 be a continuation. It stretches along the submaxillary duct 

 for about one and one-half centimeters, lying between the 

 masseter and digastric muscles. The sublingual duct leaves 

 its ventral side, passes close to the submaxillary duct, at first 

 dorsad and then mediad of it, and opens on the medial side of 

 the apex of the same papilla with the submaxillary duct. 



4. The molar gland (glandula molaris) (Fig. 65, 9) lies 

 between the orbicularis oris and the mucosa of the lower lip. 

 It stretches from the cranial border of the masseter to a point 

 between the first premolar and the canine. It is flat, broad 

 caudad, and ends in a point craniad. It has several ducts 

 which pass straight through the cheek and open on the mucous 

 surface of the mouth. 



5. The infraorbital (or orbital) gland lies in the lateral 

 part of the orbit on its ventral floor. It is ovoid and about one 

 and one-half centimeters long and one-third as thick. Its 

 ventral end rests against the mucosa of the mouth just caudad 

 of the molar tooth. Its duct leaves the ventral end and opens 

 into the mouth at a point about three millimeters caudad of the 

 molar tooth. 



The Teeth. Dentes. — The adult cat has thirty teeth, 

 fourteen in the lower jaw and sixteen in the upper jaw. There 

 are twelve incisors, four canines, ten premolars, and four 

 molars. The tooth formula for the cat is then 



.3-3 i-i ^3-3 i-i 



3—3 I — I ^ 2 — 2 I — I 



The teeth are implanted in the alveolar borders of the 

 premaxillaries, maxillaries, and mandible. In each tooth can 

 be distinguished the root, imbedded in the socket of the bone,
