made successively on the ianer side of the tendon, on the 

 outer and on its centre. 



Treatment. First subdue the inflammation by rest, a 

 high-heeled shoe and a wet rug kept hanging continually 

 over the shoulder (a blanket folded several times and tied 

 round the neck and chest), with or without a purge anci 

 lestricted diet. When the heat and tenderness have sub- 

 sided apply a smart blister over the point of the shoulder, 

 and repeat if lameness persists. In obstinate cases it may 

 be needful to use the hot iron, but only on the outer 

 side of the joint, and never on the point where the collar 

 rests. 



SPEAIN OF THE MUSCLES OUTSIDE THE SHOULDER-BLADE. 



This is a sprain of the muscle which fills up the poste- 

 rior cavity on the outer side of the shoulder-blade and 

 plays over the outer side of the shoulder-joint (outer tu- 

 bercle of the head of the humerus). It occurs mainly in 

 young horses when first put to plow or in others going on 

 uneven ground and stepping unexpectedly into holes. In 

 the endeavor to recover the eqiiilibrium on stepping into 

 a furrow or hole, this muscle which forms the outer sup- 

 port of the joint is injured and there result 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 standmg directly in 

 front of him the affected shoulder is seen to roU outward 

 from the body to a far greater extent than the sound one. 

 Soon the muscle begins to waste rapidly, and in bad cases 

 the shoulder-blade may be denuded until' it appears to be 

 covered by nothing but skin. 



Treatnif.nt. In the first stages, with heat, swelhng and 

 tenderness outside the joint, rest, employ a wet rug, etc., 

 as for sprain of the coraco-radial tendon. When this has 

 subsided allow exercise on smooth ground (walking, work- 

 ing in light cultivator,) and increase the circulation ovei 

 the ^ asted muscle ]jy active friction with straw or a piece
