Domestic animals -- Age; Teeth. of the Animals of the Farm. 40 old, aud it is absolutely necessary that he should inspect the molars, in which important changes occur between the ages of fiiteen months and t\vo years. Soon after the sheep reaches one year and a JtaJf, the sixth molar begins to protrude through the gum. Shortly after- wards the two anterior temporary molars give place to the jDermanent teeth, and the third temporary molar is a mere shell covering the top of the permanent tooth, which is coming up beneath it, and pushing it out of its place, as shown in the last illustration (Fig. 47). In this drawing the average condition of the molars of the sheep just under tico years is exhibited. The two anterior permanent molars are cut, the third permanent molar is coming up under the temporary tooth, which in many cases will have fallen out, leaving the permanent organ to be seen below the Fig. 48.—S'ii' broad teeth at two years and three level of the other teeth. At the back of the jaw the sixth molar is seen, but does not show any marks of wear, and this tooth, it may be observed, affords the most valuable evidence at a critical period. In the class " not exceeding two years," many of the sheep are stated to be twenty months old, and some of the animals may have the third pair of broad teeth not fully deve- loped, but fairly advanced. When sheep exhibited as under two years of age are found to have six broad teeth the animals are naturally objects of suspicion, and further evidence is sought for in the molars, which, as the drawing (Fig. 47) shows, exhibit very characteristic marks at this period. Generally it may be taken as a fact that if a sheep with six broad teeth shows the three anterior molars in a state which proves that they are recently cut. and especially if one or more of the temporary teeth still remain, the age does not exceed two years.
