In any instance of such exceptional dentition being found in sheep entered in the class not exceeding two years, it will be necessary to inspect the molars. If the three anterior molars and the sixth molar present evidence of having been only recently cut, and especially if one or more of the temporary Fig. 49.—Incisors of Shee}} at three years old, shoioing recently cut corner teeth. \. molars remain, the cutting of the third ^jair of broad teeth will not justify disqualification. Should, however, the molar teeth exhibit a uniform character, all their surfaces being quite level, it may be concluded that the sheep is over two years of age. Dentition in sheep is completed by the eruption of the corner permanent incisors, which are usually cut at the age of three years, as shown in the above drawing. In some cases the corner teeth are not well up till the animal is nearly four years old, so that there is a possibility of a mistake being made as to the age to the extent of a year, by an examiner who contents himself with an inspection of the corner incisors. No difficulty, however, would be experienced in deciding whether the corner incisors represent three years or tour years, if the state of the other incisors is taken into account. At four years of age the six broad teeth will show marks of.
