It was not our intention in this work to speak of Onanism and Masturbation. These unnatural practices are so generally known to be destructive to the sexual powers, and of health, that young people scarcely need advice on the subject. But it may be interesting to know the results of such practices, and of the abuse of the sexual organs by over indulgence. Some constitutions experience a sort of consumption which arises from the dorsal portion of the spinal marrow. No fever accompanies it, the appetite continues good, but the patient gradually wastes away. Women thus affected describe a crawling sensation down the spine. Men lose their seminal fluid in their urine, having a ringing in the ears, a weakness of vision, near-sightedness, and their intellectual capacities are weakened and confused. In short, the whole nervous system is generally prostrated. Excess of venery is likewise the first exciting cause of many painful diseases, such as rheumatism, neuralgia, epilepsy, convulsions, &c. Young married people are apt to indulge too much in sexual intercourse, and many a man lives a life of misery from ill health originated in this manner. Women are not affected so much by over indulgence as by Masturbation. Delicacy not allowing an ardent woman to tell her husband of her needs, she is apt to relieve herself by this unnatural practice. There are, however, but few women who crave sexual intercourse. The excess is generally on the part of the man. Moderation in sexual pleasures is the key to health in a great many cases where the patient is hopelessly lamenting his sad fate. Sometimes a man will indulge to excess without experiencing much inconvenience, when suddenly a fit of palsy or epilepsy prostrates him, and leaves him a hopeless invalid for life. I remember an interesting case in point. A man of robust health and strong sexual powers, married at the age of nineteen. From that time until the age of forty-five, he lived temperately, was regular in his habits, and never knew a day of sickness. He had always the reputation of being fond of a variety of women—indeed, this seemed to be the one passion of his life, for he dissipated a handsome property in settling crim. con. suits, and paying for bastard children. As he advanced in years his passion seemed to increase, and it was said that he supported five different mistresses at the time of the occurrence of the event I am now about to relate. One day when he was writing a letter, he felt a peculiar twitching of the forefinger with which he held his pen. This twitching sensation increased so much that he called on me for advice. I replied, “Let the women alone, for that is a symptom of palsy.” Within two days thereafter he was struck down and lost the use of his hands, his right arm, and partially of his right side. Ten years have passed, and this man, who had previously enjoyed excellent health, is still as helpless as on the first day of his misfortune. He has consulted
