THE HORSE 



At the full age of one year, the marks in the 

 central nippers will be much shorter and fainter than 

 they were at first. The lateral nippers will show 

 wear, the marks will be longer and more pronounced 

 than in the central nippers, but they will be shorter 

 and less indented than in the younger corner teeth. 

 All of the nippers will be up and the corner ones 

 will be worn level; that is, their posterior corners 

 will be fully up but not worn quite as much as shown 

 in Fig. 63. It requires some care to determine accu- 

 rately the age of the colt when it has passed its first 

 year and up to the time the central nippers are 



replaced by per- 

 manent ones. It 

 may be said , 

 however, that 

 the teeth show 

 wear and have 

 something of the 

 appearance of a 

 six-year- old 

 mouch in minia- 

 ture; but, with 

 careful inspec- 

 tion, m a n 3 r 

 minor differ- 

 ences can be observed. The teeth are shorter, that 

 is, show less above the gums, are smaller than those 

 of the six-year-old animal and have a distinct neck. 

 They are lighter colored than are those of the horse 

 of six years of age. If the teeth of the two -year -old
