SPECIAL INJURIES OF BONES. 327 



blaiie may be denuded until it appears to be covered by nothing 

 but skin. 



Treatment. — In the first stages, with heat, sweUing 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, working in light 

 cultivator), and increase the circulation over the wasted muscle 

 by active friction with straw or a piece of wood : or by mild 

 blisters (ammonia i pt., oil 2 pts. : or Spanish flies i part, 

 alcohol 25 pts., steeped for 24 hours and strained) ; or stimu- 

 late with a galvanic battery. It may take months to refill the 

 cavity, but in all recent cases perseverance will be rewarded. 

 In old standing cases with fatty degeneration of the muscles, a 

 very partial restoration only can be effected. 



It must be added that wasting of the shoulder muscles is a 

 common result of all lameness entailing disuse of the limb, and 

 hence many injuries of the feet and elsewhere are referred to 

 the shoulder and designated sweeny (Schwinden) by wiseacres. 

 In the absence of the particular gait above described, of the 

 early heat, swelling and tenderness outside the joint and the 

 rapid wasting of the muscle, the cause of the sweeny should be 

 sought elsewhere than the shoulder. 



DISEASE OF THE SHOULDER-JOINT (INFLAMMATION, 

 ULCERATION, ETC.) 



In the large quadrupeds, in which swelling and tenderness 

 on handling are rarely seen, disease in the joint is to be mainly 

 distinguished by the general symptoms of shoulder lameness 

 and the absence of any of the signs of local disease in 

 the tendons, already described. Movement of the joint by 

 drawing the limb fonvard, and especially by drawing it back- 

 ward, will usually give rise to pain, sometimes of an extreme 

 nature. 



In dogs the cjapsule of the joint is found to bulge on each
