the skia half an inch below the swelling and carried up over it 

 The part must then be covered by a wet bandage. 



INFLAMMATION OF THE MEMBRANE COVERING THE SHANK-BONE. 



SORE SHINS. 



This occurs especially in over- worked young horses. Racers 

 nre very liable, but cart-horses are not exempt. There is general 

 tumefaction of the shank-bone or of some part of it, usually the 

 lower, with a lameness greatly resembling that of splints. If 

 slight and circumscribed, the exudation that takes place between 

 the membrane and the bone is ossified, giving rise to permanent 

 thickening, and exudation outside the membrane may follow a 

 similar course, causing a very considerable swelling. In the 

 more severe cases, the abundant exudation, separating the 

 membrane from the bone, may cut off the supply of blood and 

 entail necrosis ; or the lymph may degenerate into pus which 

 burrows beneath the membrane, separating it from the bone 

 and destroying the life of the latter. 



Treatment. — In mild cases treat like splints. In the very 

 severe with great tenderness and doughy swelling of the bone, 

 make a series of incisions through the membrane covering the 

 bone, with a very narrow-bladed knife and by valvular wounds, 

 passing the blade a short distance beneath the skin before cut- 

 ting down on the bone. Then apply the lotion advised for 

 broken knees. 



FRACTURE OF THE SPLINT BONES. 



The lower ends of the small bones of the shank are liable to 

 be broken, the lesion being made out by the swelling at the 

 point and the unnatural mobility of the lower end of the bone, 

 though grating is not to be expected. No treatment is needed 

 beyond a cooling bandage and rest
