SURGICAL DISEASES . I09 



methods of relieving this condition are described 

 under the head of scrotal and ventral hernise. 



Growths or tumor formations in the scrotum and 

 at the end of the cord are common when castration 

 is not properly performed. A common mistake made 

 by the' operator is to cut too small an opening in the 

 scrotum. This does not permit the pus and other 

 secretions to drain off, and the parts become in- 

 flamed. Other causes are leaving the cord too long 

 and infection with irritating germs. Tumors in this 

 region can be considered a serious complication, as 

 they interfere with growth and may cause the death 

 of the pig. They can be largely prevented by avoid-

 tration is performed properly. 



The treatment consists in dissecting out the tumor. 

 This is a very painful operation and the pig may 

 die shortly after the tumor has been removed, espe- 

 cially if the growth is large. However, the results 

 are usually good when the operation is skillfully per- 

 formed, or if the tumor is small. In all cases, if not 

 completely removed, it is apt to grow again and give 

 more trouble than at first. 



CASTRATION OR CRYPTORCHIDS OR " ORIG- 

 INALS " 



In the " original " pig, the testicles, one or both, 

 fail to descend through the inguinal canal and make 

 their appearance in the scrotum. Usually, but one 

 testicle does not descend into the scrotum and it may
