"2. Cheeks. 3. Palate. The cheeks resemble those of the Pig; the p;date that of 

 Ruminants. The mucous nicmbrnne is often stained by patches of pigment, e:-p; ei:dly on 

 the palate." (The latter is frequently quite black. The number of ridges varies from 

 seven to nine. Jucobson's canal ojieus behind the incisors.)

thirds of the tongue are covered by a very strong horny shenth, whose point is dii 

 backwards. In the Dog these pupil la> are less developed, and there are observed, ni'Te 

 particularly, a number of composite filiform pipill.-e whose divisions ure very HiAil.le. 

 There also are found regu'rirly disjxwed among these, while sliming epithelial particles 

 which correspond to the fungi form papillae. 



"Attheba-c of the tongue of Caniivora, and within the anterior pillars of the soft 

 palate, are two elongated Ixxlies with rounded extremities and a 1 c->e!ated slippery

 isthmus of the fauces wide. Con>ei|iiently. HH-M- ere atiires breathe ea-ily by the mouth, 

 nnd expel matters by it from the stomach during vomiting. At its free border the soft 

 palate shows a small prolongat on something like the uvula.
