DISEASES OF THE GENERATIVE ORGANS 77 



hot water packs, or clothes that have been wrung out 

 in hot water, to the part, in order to keep down the 

 inflammation. This should be persevered with until 

 the acute part of the inflammation has subsided. A 

 water solution of iodine should then be applied to the 

 scrotum (iodine crystals, one and a half parts; iodide 

 of potassium, one part; and water, twenty parts). 

 Twenty grains of iodide of potassium should be given 

 in the feed twice a day for a few weeks. 



If an abcess forms, it is necessary to castrate the 

 boar and wash out the part with a disinfectant solu- 

 tion. This should not be postponed until too late, or 

 the animal may die. Degeneration of the testicles 

 sometimes occurs. Water sometimes forms in the 

 scrotum as a result of the inflammatory changes. 



WATER IN THE SCROTUM— HEMATOCELE- 

 HYDROCELE 



This condition is seldom met with in hogs. The 

 usual cause of fluid collecting in the scrotal sack is 

 an inflammation of the covering of the testicle 

 (tunica vaginalis). This may follow as the result 

 of an injury to the walls of the scrotum. A small 

 water seed (hydrocele) may occur as a complica- 

 tion of castration, when the operation is performed 

 carelessly. 



Symptoms. — The swelling is soft, elastic, and pain- 

 less, and confined largely to the lower part of the 

 scrotum. When a large quantity of fluid (serum, or 

 blood and serum) collects between the layers of the, 

 tunic or at the end of the cord, it may resemble^ a
