. The comparative anatomy of the domesticated animals. Horses; Veterinary anatomy. THE MOUTH. 427 stand up to form a grip, resting against the pad on the upper jaw much more by their extremity thau by their inner surface. They are, besides, narrow, have scarcely any neck, and are fixed more solidly in the alveoli (Fi-. 237). Their external face is white and polished, and is encased towards the gum in a of black cement. The internal face has two wide, longitudinal grooves, separated towards the middle of the table by a simple ridge, which replaces tlie conical eminence of the Ox's incisor. These groovts are nearly always lined with the black cement-like substance. The incisors of the Sheep are, like the Ox's, dijitinguished into temporary and replacing teeth; the lir»t are known from the others by their smallness, and particularly by their narrowness. The wear of the incisors in the Sheep, from their position, ought to take place nearer the anterior border than in the Ox; the dental star is observed earlier, and always forms a narrower line from before to behind. yW. 237. The absence of a neck in these teeth is the reason why they never appear to separate with wear, as has been remarked in those of tlie Ox. The molars have the greatest resemblance, in their general form and relative proportions, to those of the Ox. The teetii of the adult Camel are thirty-four in number— six incisors in the lower maxilla, ten molars and six teeth re- sembling canines, two of which are fixed in the premaxilla. In incisor tekth of a sheep the young animal, the tHcisocs—the free border of wliich is sharp two years old. as in the otlier Ruminants—are much inclined on the maxillary The second laterals aud the border, but become erect as the creature grows older, so as to corner incisors have not resemble those of the Horse. yet been replaced. The cnnines of the lower jaw are strong and pointed ; among of the upper jaw, the laterals only are greatly developed, and some
