the pint), or oth&r suitable antiseptic (p. 67). If any omentum 

 (p. 282) protrudes, it should be pulled up, cut off, and treated with 

 the antiseptic lotion ; for if it is allowed to hang down when the 

 animal gets on his legs, it will soon become united 'to the wound 

 in the scrotum, and form an unhealthy tumour. The animal may 

 now be allowed to get up, and should be kept on green food for a 

 week. The wound, to keep oS flies, may be smeared over, from 

 time to time, with an ointment composed of creolin or carbolic 

 aoid and vaseline (1 to 30), powdered aloes and lard or vaseline, 

 or turpentine and lard (1 to i). Or the wound may be syringed 

 out, every now and then, with a solution of chinosol, creolin or 

 carbolic acid (p. 67). 



After this operation, there is generally a little bleeding, which 

 will soon stop of its own accord. 



2. BY THE HOT IRON.— The procedure by this method is the 

 same as already described, up to the putting on of the chain, in- 

 stead of which a clam is passed underneath the testicle and around 

 the cord, close to the belly, and is secured by a ring which passes 

 over its handles, by a ratchet, or a screw ; the first being the 

 simplest plan, though the third is probably the most efficient. 



The clam is an instrument used for compressing the cord, and 

 is composed of two pieces of flat steel, which have serrated edges 

 and are united by a joint. The ends away from the joint are 

 formed into handles. The clam should be made extra broad if it 

 is to be used with the hot iron, in order that it may save the 

 thighs from being burned. 



If a broad clam cannot be obtained, the scrotum and inside of the 

 thighs should be protected from the heat by covering them with 

 wet cloths. The operator should take a hot firing iron, which 

 should be clean and free from all scales, and burn through the 

 cord and surrounding tissues at a distance of about half an inch 

 from the clam. The iron should be maintained at a dull red heat, 

 and be freely applied to the cut end of the cord and also to each 

 side of it, so as to prevent any chance of bleeding. The clam is 

 now gradually relaxed. The hot iron should be reapplied in the 

 event of bleeding ensuing before the clam is finally removed. The 

 right testicle is treated in a similar manner. After the cord has 

 been severed, the finger should be introduced into the wound, and 

 the end of the cord freed from any adhesions which may exist 

 between the cord and scrotum. 



If, after the operation, excessive bleeding takes place, treat as 

 directed on p. 114.
