four or five times a clay with sulphate of copper and pulverised 

 charcoal in equal parts ; inflammation results, and in a few days a 

 scab forms, after which the prolapsed part sloughs off in eight to 

 fourteen days. Danish practitioners have used this material with 

 success in large animals and swine, but others consider it useless ; 

 Weber, after trying it in foals was finally forced 

 to operate. It can, of course, only be used in 

 prolapsus ani et recti, without invagination. Apart 

 from the uncertain action of this treatment, it 

 must be remembered that it is often followed by 

 extensive contraction of the anus and difficulty in 

 defalcation, and most practitioners, therefore, pre- 

 fer amputation. 



(2.) Ligation has been adopted by Viborg and 

 Stockfleth in the case of pigs, dogs, and foals. As 

 Stoekfleth's wooden it is necessary to keep the anus open for the 

 nng- passage of faeces, Stockfleth binds a ring of wood, 



1 to 2i inches in diameter, in the anus ; to prevent the ligature 

 slipping off, the ring has a shallow groove on its surface (Fig. 423). 

 The prolapse is divided up to the anus, the ring then thrust in, 

 and a stout ligature passed around it and the prolapsed bowel, 

 which slowly cuts through, until finally the portion of intestine

beyond the ring is cut off. During the next few days defa?cation 

 must be assisted by clysters, and bulky and indigestible foods 

 avoided. The tube falls away spontaneously in five or six days, 

 and as a rule healing is then complete. Sorensen in this way 

 amputated a piece of bowel, weighing 23 ounces, in the horse. A 

 case of Johne's, however, in the pig, shows' that after ligation 

 stenosis, and even complete occlusion, may occur.
