" Solace" (Fig. 18) at the age of ten years, it will be seen that 

 there are certain important differences. The central incisors 

 have quite lost the " mark," which is only represented by a dot. 

 The central enamel in the remaining incisors forms a much 

 smaller figure than in the ten-year-old teeth. The corner teeth 

 have become more oval in form, and only a trace of the central 

 enamel can be seen. 



Aftei' twelve or fourteen years of age, the evidence which is 

 afforded by the tables of the teeth is not definite enough to 

 justify a positive opinion as to the animal's age, and the illustra-

tions (Figs. 20, 21), which are accurate representations of 

 the teeth of the thoroughbreds " Kremlin " and " Epirus," will 

 show how far the appearances may differ in animals of the 

 same age. Both horses were foaled in 1831, and the drawings 

 show the state of the teeth in 1853, when the animals were 

 nineteen years old. 



In both cases the teeth form a more acute angle with the 

 jaw than is u^ual at this age. In this particular both mouths 

 agree, but in other respects they differ from each other to a 

 noteworthy extent.
