Bat there is a hard variety of windgall, where the small 

 " sesamoid ^' bones themselves are inflamed, and tliis is a more 

 serious matter. The horse is then lame, going on his toe, 

 and there is heat and and swelling at the back of the fetlock. 

 The swelling is lense and hard, quite different from the 

 "boggy" feel of common windgall. 



For the relief of the latter, it is recommended to place the 

 animal in slings, and to bathe the part steadily with cold 

 water ; when the tenderness lessens, give him rest, and let

CURB. 



Definition. — A sprain of one of the ligaments of the foot

Symptoms. — Curb presents itself in some instances as a

 firm and easily seen protuberance on the back of the hock, 

 four to five inches below the point of the heel bone (os calcis). 

 Hocks which are bent over are most liable to curb. 



The lameness curb produces is marked by difficulty in ex- 

 tending the hock, and in some severe cases by the animal 

 keeping the limb elevated so as to relax the ligaments. 



Treatment. — The shoe should have a high heel, and the 

 part be placed at rest and treated with cold water and cool- 

 ing lotions as long as any inflammation remains, as evidenced 

 by heat and tenderness. 



When this has disappeared, it will often be found that 

 the swelling remains in a chronic condition. To induce its 

 absorption, steady friction with an absorbent ointment is 

 usually successful, as —
