ease. It is beyond the reach of the surgeon. It is not known 

 that any internal disinfectant can efficiently reach the or- 

 gan. With the bacteriology virtually undetermined, vac- 

 cines, bacterins, and other biologic products can not be ad- 

 vocated. The most that can be suggested thus far is sexual 

 rest and good general hygiene with, as a rule, eventual 

 slaughter. 



2. Diseases of the Prostate and Cowper's Glands 



The pathology of the prostate glands of animals has not 

 been studied except in the dog, where apparently the gland 

 suffers frequently from disease. While the gland is an ex- 

 tensive one in the bull, it is so enveloped by Wilson's muscle 

 that it is not directly palpable. There is nothing in veteri- 

 nary literature indicating to what, if to any appreciable ex- 

 tent the prostate of cattle becomes diseased. 



In the bull Cowper's glands lie deeply buried beneath the 

 ischio-cavernosus muscles, where they are not palpable un- 

 less enormously enlarged. I find no record of disease in 

 them. 



D. Balanitis. Balano-Posthitis 



In Chapter XII, under "The Nodular Venereal Disease," 

 balanitis and balano-posthitis have been quite fully discussed 

 as one of the practically universal results of that infection 

 or lesion in ruminants and swine. While other infections 

 (aside from tuberculosis and actinomycosis) may invade 

 these parts, they offer nothing of special interest so far as 

 is known at present. The general principles of control in- 

 dicated for the nodular venereal disease are applicable to 

 any infections of a general character which may be added 

 to or associated with it.
