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 1 - 1 3 - 3 1 - 1 _i_-----, _c_-----, _pm_-----, _m_-----. 3 - 3 1 - 1 2 - 2 1 - 1
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, the =crown=, which projects above the gums, and a narrow =neck= connecting the two. The root is composed of one or more separate fangs; the crown bears one or more points or cusps.
At the cranial end of each jaw are six =incisor= teeth (Figs. 93 and 94, _a_). These are imbedded in the alveolar borders of the premaxillaries and the mandible. The incisor teeth are small, with a crown bearing a sharp edge which is notched so as to form three minute cusps. The root of each has a single fang. The lateral incisors are the largest in each jaw, and those of the upper jaw are larger than those of the lower.
