Fig. 32. 



the least deviation from the straight line proper to the limb 

 will be at once detected. 



The seat and true character of Curb will perhaps be more 

 satisfactorily explaiued and understood by reference to the 

 annexed engraving. 



The engraving represents the 

 puter side of the left hind limb of a 

 horse, dissected. The figure is partly 

 diagram atic. In describing the en- 

 graving I shall merely refer to those 

 letters which relate to the structures 

 more or less involvedin Curb ; a the 

 tendo achilles, two tendons of great 

 strength which are situated above 

 the point of the hock and behind the 

 Hmb ; 6 the os ealcis, or the bone 

 which forms the prominence of the 

 hock ; e the head of the outer splint 

 bone ; df the flexor tendons — these 

 tendons are a continuation of the ten- 

 do achilles; cthe calcaneo cuboid liga- 

 ment. This ligament arises towards 

 the top of the os ealcis bone I, and 

 is inserted into the back of the small 

 bones of the hock, and also to the 

 head of the outer splint bone. Now 

 Curb is simply a sprain of this liga- 

 ment ; sometimes, however, it is 

 associated with sprain of the flexor 

 tendons at the point d, in which case| 

 the swelling will be more promment, 

 and the lameness wUl also be more apparent.
