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 eee 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 
2s ce — a jn, ss,

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,
