HEALTH AND DISKASK 



In some severe cases of this deformity the lower row of incisor teeth are 



allowed to come into contact 

 with the roof of the mouth 

 and injure the bars or palate. 

 In such cases the offending 

 teeth should undergo period- 

 ical rasping to keep them 

 down. 



CRIB-BITING 



A practice in which some 

 horses indulge has the effect 

 of wearing down the incisor

outer edge (fig. 129). It is very seldom, however, that any dental disease 



or derangement arises out of it.

of the series has long since dis-
