(prostate, vesicul^ SEiriNALEs, cowper's glands.) inflammatory or other diseases of the above glands are most fre- quent in entire animals. As a group they are uncommon, and are still ill-recognised and ill-described, being seldom identified excejDt on post-mortem examination. The cause of inflammation of the prostate, of the vesicuhie semi- nales, and of Cowper's glands is probably an ascending infection of the urethra and neighbour- ing channels, a fact which ^ " explains the comparative rarity of such conditions in castrated animals. The pathogenic germs penetrate from the urethra into the excretory ducts of the glands, obtain a lodg- ment in the culs-de-sac of the glands themselves, and thus produce simple or sup- purative inflammation. The symptoms may easily be mistaken, to some extent at least, for those of acute cystitis or cystitis due to the presence of a cal- culus, and it is only by rectal examination that the diagnosis can be made. The first symptom is defective micturition, which occurs in jets, is intermittent and painful, and sometimes causes slight groaning. It is accompanied by vesical colic, spasmodic lifting of the hind legs, and more or less unsuccessful expulsive efforts. These symptoms are of reflex or mechanical origin, and are due either to direct compression of the urethra by an hypertroi^hied and inflamed gland, or to spasm of the vesical sphincter. The urine passed, unlike that in cases of acute cystitis or in cystitis due to calculus, is of a normal character. Rectal examination usually re- veals distention of the bladder, and hypertrophy and exceptional sen- sitiveness at certain points. If the painful and hypertrophied area is over the neck of the.
