422 A TREATISE ON HORSE-BREEDING. 



exactly as they appeared in the summer of 1852, and fairly 

 represent the characters of the ten-year-old mouth. 



In Fig. 15 the appearance of the eight-year-old mouth is 

 shown. The drawing was copied from the mouth of Peep o'- 

 Day Boy in 1852. The horse was foaled in 1844. 



At twelve years old the teeth are longer from the receding 

 of the gums, and are also narrower in consequence of having 

 been worn toward the fang, which decreases in width from 

 the neck of the tooth to its termination. The tusks are 

 blunted, especially those of the upper jaw, and a quantity of 

 tartar often surrounds those in the lower jaw. The incisors 

 at this age project almost in a straight line from the jaws, 

 and in some mouths a line drawn transversely across the 

 tables of the teeth will cut the centers of all of them except- 

 ing those of the corner teeth. 



Fig. 16 represents the teeth of the Thoroughbred horse 

 Lothario, foaled in 1840, as they appeared in 1852. 



After twelve or fourteen years of age the evidence which 

 is afforded by the teeth is not definite enough to justify a 

 positive opinion as to the animal's age.
