This is a sprain of the muscle which fills up * 

 the posterior cavity on the outer side of the 

 shoulder joint (outer tubercle of the head of 

 the humerous). It occurs mainly in young 

 horses when first put to plow,, or in others go- 

 ing on uneven ground, and stepping unexpect- 

 edly into holes. In' the endeavor to recover 

 the equilibrium on stepping into a furrow or 

 hole, this muscle which forms the outer sup-

 heat, swelling, and tenderness on the outside 

 of the joint, and a most characteristic gait. 

 The horse may walk, or even trot, without 

 much apparent lameness ; but standing directly 

 in front of him the affected shoulder is seen to 

 roll outward from the body to a far greater ex-

 gins to waste rapidly, and in bad cases the 

 shoulder-blade may be denuded until it appears 

 to be Covered by nothing but skin. — Lam.

rise to it. A prominent cause also 



is some injury to the, foot, which would prevent a proper use of 

 the muscles of the shoulder, and thereby cause an atrophied, of 

 wasted, condition of them. So that when there is wasting of the 

 part, the foot should be carefully examined to see if there is any 

 cause for it, and if so, removing the cause will of itself be sufficient to 

 make a cure. 



Symptoms. — At first, though it is seldom noticed, the muscles 

 swell up, are hot and tender ; in the course of a few days, the swell- 

 ing has disappeared, and the muscles are becoming fast absorbed. 

 In many cases this goes on till the bone can be felt. There is little
