The Dental record . position. Any error of opinion as to the age which might arise fromthe premature cutting of the central permanent incisors may becorrected by reference to the state of the molars. In the next illustration (Fig. 29) the sixth molar is shown in theFig. 29.—Showing the Sixth Molar at two years. r. i sTt-W p. M. ST-rii\Q^~§^^ THE DENTAL RECORD. 267 position described, and in the same figure the first and second perma-nent molars have taken the places of the temporary teeth ; this change,in my own experience, does not usually occur until the animal is amonth or two over two years of age. From two years and three months to two years and six months thesecond pair of broad teeth, the middle permanent incisors, occupy theplace of the corresponding temporary teeth in all the cultivatedbreeds. Instances of late dentition present themselves from time totime, in which the middle permanent incisors are not cut until theanimal is approaching three years old. There is consequently aa possible variation of six months in the time of the appearance ofthese teeth. In the illustration (Fig. 30) the ordinary condition of the incisors at Fig. 30.—Incisors of Gx at two years and six months.
