"Diurnal Emissions.-As the disease progresses, the irritation and weakness of the organs become so great that an erection and emission occur upon the slightest sexual excitement. Mere proximity to a female, or the thought of one, will be sufficient to produce a pollution, attended by voluptuous sensations. But after a time the organs become so diseased and irritable that the slightest mechanical irritation, as friction of the clothing, the sitting posture, or riding horseback, will produce a discharge which may or may not be attended by sensation of any kind. Frequently a burning or more or less painful sensation occurs ; erection does not take place. Even straining at stool will produce the discharge, or violent efforts to retain the feces when there is unnatural looseness."
