"If tlie animal m question is a bull of one of the cultivated breeds, and has been forced to a state of early maturity, it may be expected that the second pair of permanent incisors will have been cut at two years and four mouths; and if either of the anterior temporary molars remain in their places, the conclusion that the animal is under two years and a half will Ije strengthened. "Shortly after the first and second molars are cut the third makes its appearance; occasion- ally it appears be- fore the others, and the animal at the age of three years will have three anterior mo- lars nearly level with the other teeth, but showing no signs of wear. " The eruption of the third pair of permanent incisors may occur at any time between two years and six months and three years of age. In cultivated breeds they are present as a rule before the ani- mal is three years old, and occasionally they will be found well develojjed after two years and a half. In fact the anterior molars afford more reliable evidence of the age between two and a half and three years old than is furnished by the incisors. "The fourth pair of broad teeth, the corner permanent incisors, are more subject to varia- tion in the time of cutting than the third pair. In well bred cattle they take the place of the temporary teeth soon after the completion of the third year, but in bulls they are not uncom- monly present at two years and ten months old, while in some instances they are not cut until three years and nine months old. Very little reliance, indeed, can be placed on the evidence of the corner incisors, and the examiner is com- pelled to refer to the molar teeth for the pur- pose of correcting his opinion., "With the eruption of the corner perma
