DISEASES OF 



drams of Aloes. The diet should be somewhat re- 

 stricted. 



In figure 22 is seen a drawing of the results on the 

 metacarpal bone of a severe attack of sore shins. It 

 will be seen that the bone is very much roughened from 

 the extensive inflammation. 



SPLINTS. 



Splints are tumors of the metacarpal bones. They 

 are peculiar to the inside of the leg, and are usually 

 situated from the middle of the metacarpal to two inches 

 below the knee. 



Causes. In the evolution of the horse from three 

 toes to one toe, the two side toes have gradually tended 

 to become united to the center toe (see figure 23).
