Fig. 139. 



Nine Years (Figs. 137, 138, 139).— These plfites are from the teeth 

 of a horse nine years of age ; the dental cups are of a size and sha|)e 

 representing a 3-onnger age. In profile, tlie incidence of the teetli is 

 seen to be that of a horse five or six j-ears of age ; the inferior tables :ne 

 round ; the central enamel incloses small cups close to the posterior 

 border of the teeth. The corner teeth are leveled and rounded ; tlie 

 dental star is near the middle of the teeth. These characters, added to 

 the freshness of the corner teeth, the obliquity of the inferior incisors, 

 the notch on the upper corners, and the general condition of the subject, 

 are sufficient to rectify any error indicated by the first inspection.
