“I am led to believe,” (adds he,) “that the effects of onanism would not be so pernicious, were it not for this diurnal pollution; that without it, this shameful habit would not be followed with consumption, and other symptoms of phthisis. In fact, onanism does not always give rise to this pollution. If this were the case, the number of onanists affected with consumption would be very great. The number of men addicted to this vice from early childhood is immense; for we do not know a greater scourge than this social corruption. From the fact, too, that onanism sometimes produces involuntary diurnal pollution, we ought to investigate if it does not exist in those who have renounced this pernicious habit. Advice to them would be useless, inasmuch as, having renounced this vice, they do not suspect the enervating cause which destroys them. About eighteen years ago, before I had discovered this cause of consumption, I knew a young man, thirty years old, who had been addicted to masturbation from the time he was ten years old, and who learned this pernicious habit from his preceptor. He died, after experiencing all kinds of infirmities, with extreme debility of all his physical and moral faculties. He acknowledged his error, and that for a long time he had renounced his bad habit; but his late return to continence did not save him. Now, I feel confident that this shameful habit had brought on an involuntary diurnal pollution, which caused his death.” Wichmann remarks, that it is at the commencement of the fine season of spring that the patients are most conscious of their situation. They owe this increase of their ills (says he) to that general procreative faculty which becomes more active in all animated beings at this period of the year. The more full the vesicles of semen, the more liable are patients to lose it. We must also remark, that most patients secrete prolific semen, and preserve their procreative power. This, however, requires the patient to have the faculty of erection; for, otherwise, he would be impotent. This was the case with an individual, whose case is stated by Henry Van-Hers.
