CLINICAL VETERINARY MEDICINE AND SURGERY. 



From the 15th to the 30th treatment consisted in applying to the 

 necrotic parts a mixture of sulphate of iron and sulphate of copper, 

 and in spraying the parts daily with creolin, followed by application of 

 a dressing saturated with traumatol. 



Under the influence of the spray and of the traumatol, especially of 

 the former, suppuration diminished, and swelling became confined to 

 the right side. It surrounded an opening, at the base of which a 

 necrotic fragment of the ligament could still be seen. The parts were 

 again opened, allowing the spray to play directly on the necrotic 

 point, which was cauterised with a mixture of the sulphates of iron

and copper. Under the action of the 2 per cent, creolin and i per 

 cent, lysol spray the eschar separated in a few days. 



The wound finally granulated throughout, and healing became 

 assured. 



During the following days suppuration was trifling. Both wounds 

 (Figs. 34 and 35) made regular progress towards cicatrisation. 



Remark. — Antiseptic treatment, when thoroughly carried out, often 

 gives good results in the treatment of fistulous withers, and in fistula 

 of the neck and poll ; but even when supplemented by removal of 

 necrotic fragments of the supra-spinous ligament and the cartilaginous 

 layer covering the superior spinous processes, recovery is frequentl}- 

 slow and uncertain. Sometimes necrosis has extended beyond the 

 limits of the tissue removed, especially in front ; sometimes the sup- 

 puration which accompanies large operative wounds itself causes 

 recurrence. In the case just mentioned, despite excision and the 

 observance of ordinary antiseptic methods, necrosis twice recurred in
