NATURAL HISTORY OF THE HQRSK^ 



EiaHT days' TEETn. 



was unknown until a recent date ; and, in the latter case, in 

 America horses are little used in harness, or for general work^ 

 until they have attained to live or six years. 



We will next consider the first appearance and successive 

 changes of the teeth, with the marks and 

 their descriptions from commencement to 

 maturity. 



Seven or eight months before the foal is- 

 born, the germs or beginnings of the teeth 

 are visible in the cavities of the jaws. At 

 the time of birth, the first and second 

 grinders have appeared, large, compared 

 with the size of the jaw, seemingly filling it. 

 In the course of seven or eight days, the two centre nippers 

 are seen as here represented. 



In the course of the first month, the third grinder appears, 

 above and below ; and not long after, and generally before^ 

 six weeks have expired, another incisor above and below 

 will be seen on each side of the two first, which have 

 now considerably grown, but not at- 

 tained their perfect height. This cut 

 will then represent the appearance of 

 the mouth. 



At two months, the centre nippers 

 will have reached their natural level, 

 and between the second and third 

 month the second pair will have over- 

 taken them. They will then begin 

 to wear a little, and the outer 

 edge, which was at first somewhat- 



THREE OR FOUR MONTHS TEETH.
