always more forward than the inside edges. It should 

 also be noted that these new teeth are fully twice as 

 long laterally as they are thick. In Fig. 60 are shown 

 the lower nippers when the colt is from four to six 

 weeks of age. The central pair of nippers shows 

 wear and the lateral pair is through, but the inside 

 and the posterior corners are not fully up and show 

 clearly that they have not been in wear. The per- 

 manent teeth show the 

 same characteristics 

 when new; that is, the 

 inside and the posterior 

 corners do not come up 

 nor come in wear as 

 soon as do the outside 

 and the anterior cor- 

 ners. Note lhat the 

 cups, or marks, in the 

 central pair are not 

 quite so deep nor so 

 long as they were when 

 coming into wear, as shown in Fig. 59. 



When the colt reaches eight to ten months of age, 

 the teeth will appear as shown in Fig. 61. The 

 corner nippers are up but not fully in wear on the 

 inside and the posterior corners. The posterior cor- 

 ners of the last pair of nippers, both in the colt and 

 horse, come up and get in wear more slowly than do 

 the posterior corners of lateral nippers. Note, too, 

 the changes which have taken place in the cups and in 

 the shape of both the central and the lateral nippers.
