One Year (Figs. 53, 54:, 55). — All of the deciduous incisors can be 

 seen from in front ; the pinchers and intermediate teeth are entirel}^ free 

 from the gums. In profile the superior corner teeth are not yet in con- 

 tact with the inferior teeth. The tables show a decided use on the pos- 

 terior borders of tlie intermediate teeth, which, however, is subject to 

 variation, according to the height of the posterior border in different 

 colts. Tliere is generall}^ seen at this time in the anterior border a 

 yellow line, elongated transversely, which represents the elementary 

 dental star. The corner teeth are still virgin. Comparison must be 

 made between the wear of the pincher teeth and that of the borders of 

 the intermediate teeth, and according to the amount of use which the 

 latter have had the animal can be judged as rising or off the age indi- 

 cated by the other marks.
