of wood : or by mild blisters (ammonia 1 pt., oil 2 pts. : or 

 Spanish flies 1 part, alcohol 25 pts., steeped for 24 hours 

 and strained) : or stimulate with a galvanic battery. It 

 may take months to refill the cavity, but in all recent 

 cases perseverance wiU be rewarded. In old standing 

 cases with fatty degeneration of the muscles, a very par- 

 tial restoration only can be effected. 



It must be added that wasting of the shoulder muscles 

 is a common result of aU lameness entailing disuse of the 

 limb and hence many injuries of the feet and elsewhere 

 are referred to the shoulder and designated sweeny (Schtvin- 

 den) by wiseacres. In the absence of the peculiar gait 

 above described, of the early heat, swelling and tender- 

 ness outside the joint and the rapid wasting of the mus- 

 cle, the cause of the sweeny should be sought elsewhere 

 than the shoulder. 



DISEASE OP THE SHOULDEK- JOINT (iNELAMMATION, 

 ULCERATION, ETC.) 



In the large quadrupeds, in which swelling and tender- 

 ness 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. Move- 

 ment of the joint by drawing the limb forward, and espe- 

 cially by drawing it backward, wiH usually give lise to 

 pain, sometimes of an extreme nature. 



In dogs the capsule of the joint is found to bulge on 

 each side of the coraco-radial tendon which plays over 

 the point of the shoulder, and tenderness may be shown 

 when it is handled. 



Treatment. When inflammation is very severe rest and 

 soothing measures should be first resorted to. In the 

 majority of cases it assumes a subacute type and is to be 

 treated by a high-heeled shoe, rest and counter-mifcants, 

 Eepeated bhstering with Spanish flies may suffice, but in 

 obstinate cases and whenever there is reason to suspect
