In 1829, we prescribed for a young man, whose career was much more rapid. He had always enjoyed excellent health; and his parents exhibited no marks of consumption. Having married a very pretty widow, he indulged himself with her very freely at night, while during the day both were assiduously engaged. The female was seven or eight years older than her husband, and did not suffer much. He, however, soon became affected with cough, attended with bloody expectoration. When consulted, we informed the patient of his danger, unless he changed his mode of living. Our advice was not followed; and shortly after, hemorrhage from the lungs supervened so abundantly and obstinately, that notwithstanding the most active treatment, he died in eight days. The young man, too, mentioned by Tissot, was also doubtless affected with phthisis. “He came to Montpelier to pursue his studies; but was affected with phthisis, from excessive onanism: and I remember that his cough was so hard and constant, that all those who were near him were incommoded by it. He was frequently bled; doubtless, with a view to his relief. On consultation, he was ordered to go home, and take turtle soup; and two hours after, he died.” It is with phthisis, as with most of the other diseases, caused by masturbation. This habit causes disease, by cherishing and by cultivating special dispositions. Thus, the onanist born of consumptive parents, whose chest is narrow, with a long neck and thin limbs, and who presents symptoms of scrofula, is more liable to be affected with phthisis or consumption. This was the case with a young man, as mentioned by Rozier. This patient was evidently scrofulous, and many members of his family had been affected with the disease. He remained, however, pretty well until he was eighteen years old, when, in consequence of a contusion in one of his legs, he became affected with an ulcer, which was a long time healing. After it was cured, however, he remained in good health, and was lively, animated, and intelligent; but when twenty-five years old, he commenced indulging in onanism. He soon felt oppression at the chest, and cough; and although the affection of his chest increased, and he was aware of the dangers of onanism, he continued to indulge. Many physicians were consulted; but he did not mention his bad habit. The affection of the lungs continued; his sleep was interrupted; hectic fever supervened; his cheeks were tinged with an unnatural color; and his expectoration was grayish and purulent. The patient then decided on avowing his habit. Rozier attempted, in the most touching and persuasive manner, to induce him to abandon it; but in vain. Consumption continued to progress; and he was soon unable to talk, to move, or to make the least motion, without danger of suffocation. After remaining in this horrid state three years, the patient died.
