right side, and the diseased Hmb fixed to the corresponding hind Hmb. 

 The internal branch of the sole and the wall of the heel being loose 

 were completely removed. The sinus was cleansed and laid open in 

 front ; from either side of the incision a slip of the velvety tissue and 

 of the plantar cushion was removed. A necrotic fragment was then 

 seen, formed by a portion of the plantar cushion and the lateral 

 cartilage. This fragment was removed with the knife, and the base of 

 the wound curetted. After cleansing with sublimate solution the 

 margins of the wound were touched with tincture of iodine, covered 

 with a layer of europhene, plugged with gauze, and enveloped in a 

 cotton-wool dressing. 



On the following days there was no stabbing pain. The tempera- 

 ture did not exceed 38*7° C. At first weight was sparingly placed on 

 the foot, but the tread afterwards became more and more firm. 



On the 28th the horse scarcely showed lameness at a walk. The 

 dressing was renewed, the wound being found to contain little pus and 

 to be healing well. The parts were dressed a second time with euro- 

 phene. At the end of a few days weight was firmly placed on the 

 foot, and the temperature was normal. 



On the 4th June the wound was covered with granulations ; swell- 

 ing of the coronet had ahnost entirely disappeared. A bar shoe and 

 tow dressing were applied. 



The animal left hospital on the nth June, at which time it no 

 longer appeared lame at a walk. 



Remark. — Before the introduction of antisepsis, operation for com- 

 plicated corns was often followed by a return of necrosis in the lateral 

 cartilage or in the plantar cushion, and sometimes by their extension 

 to the plantar aponeurosis. In both cases it finally became necessary 

 to excise tissues very freel}'. At the present time free removal of the 

 necrotic tissue, careful curettage of the base of the wound, and anti- 

 septic dressing almost always secure healing.

162. A pure bred Clj'desdale stallion. 



History. — The origin of the growth was a severe quittor, which 

 affected the whole of the subhorny tissue, sinuses running in all direc- 

 tions. These were successfully treated, but a gradual increase of 

 granulating tissue; then occurred around the coronary band. For 

 about two years this increase was slow and interfered very little with 

 the animal's work, but a sudden increase then occurred, so that in a 

 few months the foot could scarcely be raised from the ground. 



Although operation held out little hope of success, it was resolved 

 on for lack of other remedy. 



Operation. — The animal was cast and chloroformed, a tourniquet 

 was placed above the hock, and the growth removed (with little 

 haemorrhage) as completely as possible. As the tumour practically 

 encircled the foot, and extended, with oedema, as far as the hock-joint, 

 it was impossible to remove the whole of the diseased tissue, so that 

 only so much was excised as it was believed would enable the animal
