These belong strictly to the province of surgery, but they fall also under the notice of the physician. Tubercular disease may involve the whole mucous surface or only the neck of the bladder; cancer may infiltrate its walls or grow out as a solid tumor in the vesical cavity; fibrous, sarcomatous, and myomatous new formations, polypi, and cysts, simple and hydatid, have been encountered; villous growths, both benign and cancerous, may occur. These morbid deposits give rise either to recurrent hemorrhage or to varying grades of chronic cystitis. The diagnosis is often difficult, the treatment generally palliative. Much has been done of late in an operative way for the relief of tumors of the bladder, and some brilliant results have been secured by operations through the perineum as well as above the pubes. A tumor of moderate size may be detected by the searcher within the bladder, and often may be grasped in a lithotrite and measured. Such a tumor can generally be plainly felt by conjoined palpation in a thin subject, one hand pressed firmly down behind the pubes and two fingers of the other hand passed into the rectum. Recently, Sir Henry Thompson has advocated vesical exploration for purposes of diagnosis through a median incision in the perineum, as for median lithotomy, and has practised it a number of times with a large measure of success. I have made the same exploration several times, and have encountered and successfully removed one tumor. The expedient is worth bearing in mind for use in any obscure cases. It is probably less objectionable and more likely to yield valuable information than the exploration by introducing the whole hand into the rectum (Simon's method). {137} SEMINAL INCONTINENCE. BY SAMUEL W. GROSS, A.M., M.D. DEFINITION.--By the term seminal incontinence, which is synonymous with involuntary or abnormal seminal emissions, pollutions, and spermatorrhoea, is meant the involuntary discharge of semen beyond the limits of health. Although usually described as a distinct disease, it is symptomatic of, and, as a rule, primarily dependent upon, weakness or exhaustion, along with exaggerated irritability, excitability, impressibility, or mobility of the centres which preside over erection and ejaculation. Hence it should be regarded as a motor neurosis, and not as a functional disorder of the testes.
