A case is described of a man, æt. 43 years, cured by indirect suggestion, without any apparent lesion of his urinary apparatus except some urethral spasm, the chemical composition of the urine being normal; he micturated twenty to thirty times in the twenty-four hours, and passed large quantities of urine. Born of a hysterical mother, he was himself hysterical, with such stigmata as zones of cutaneous and mucous hyperesthesia, loss of taste and smell, concentric narrowing of the visual fields, and almost complete absence of pharyngeal reflex. The pollakiuria presented by this patient was more obstinate and more obvious than is usual in these cases; not only was there frequency of micturition (simple pollakiuria, or pollakiuria proper), but also an imperious desire to satisfy the act. The cure by indirect suggestion consisted in the daily administration of pills of methylene blue. In another case mentioned—a hysterical woman—the symptoms of polyuria, simple pollakiuria, and imperious pollakiuria, with identical characteristics to the above, were induced by hypnotic suggestion.
