Horses of all ages suffer more or less from long, 

 sharp and projecting points which are often found 

 on the molar teeth. They are situated on the inside 

 of the lower and on the outside of the upper molars, 

 and also occasionally, but rarely, on the inside of 

 the upper molars. They vary much in size and 

 shape, some being small and blunt, while others are 

 long and very thin and sharp. The injury they pro- 

 duce will be in proportion to their length and the thin- 

 ness of their edges or the sharpness of their points. 



The external surface of each upper tooth usually 

 contains two of these projections, which correspond 

 with the ridges already described as running from 

 the table surface to the roots of these teeth. 



The internal surface of the lower molars also 

 contains two sharp projections, which usually are 

 much shorter though sharper than those on the 

 upper teeth. 



These projections are the result of limited lateral 

 motion of the lower jaw. In masticating its food
