Dentition of the Sheep. The terms which are applied to the teeth of the ox for the purpose of description may be used in regard to the teeth of the sheep. Eight incisors, central, lateral, middle, and corner teeth, are found in front of the lower jaw only, the corresponding part of the upper jaw being provided with an elastic pad, as in the ox. Molar teeth are designated by numbers, to indicate their position, and for the purpose of judging the age. These teeth Fig. 41.—Incisors of Lamb at in the sheep may be described as corresponding to the teeth of the ox in all general points, except in regard to their size. At hirth, the arrangement of the incisor teeth of the lamb is peculiar, as shown in Fig. 41. Grenerally the whole temporary set of teeth may be recog- nised, but only in outline, as they are nearly covered with the gum. The central incisors are most advanced, and next in order come the laterals, leaving the middle and corner teeth considerably below them. Very often the catting edges of the front and third pairs of teeth are through the gum. All these peculiarities are seen in the illustration, which may be accepted as a representation of the ordinary appearance of the teeth of the lamb at birth. By the end of the fourth rceeJc all the temporary teeth, eight incisors, and three molars on each side of the upper and lower jaws, are well Please note
