DISEASES OF THE HOG. 219 
HYDROCELE (WATER IN THE SCROTUM.) 
This derangement is sometimes the result of 
inflammation of the scrotum or by the walls of the

of which is passed through a solution of carbolic 
acid. But this should be done only by a veteri- 
narian. 
STERILITY. 
This derangement happens more commonly in 
the well bred animal, especially in those that are 
“forced” by overstimulating food. The animal gets 
into such a plethoric state that it sometimes blocks 
up the fine tubes connected with the organs of gen- 
eration. There are several other distinct causes: 
Disordered ovaries, obstructions to the fallopian 
tubes, a morbid condition of the uterus, hardening 
of the neck of the uterus. In the pig, on account of 
not being able to make an examination by the - 
hand, it is very difficult to find the cause, and if we 
did it would likely be impossible to remove it. 
Sows should be kept in good growing condition, 
but avoid having them overfat. If the animal takes
