HYDROCELE (WATER IN THE SCROTUM.) 



This derangement is sometimes the result of 

 inflammation of the scrotum or by the walls of the

 off the fluid with a hypodermic syringe, the nozzle 

 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 w^ell bred animal, especially in those that are 

 "forced'' by overstim ulating 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 tlie 

 hand, it is very dififlcult 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
