May I be allowed one question, which occurred to me when I read this observation? It is this: Can such as blow their brain out with a pistol, who drown themselves in a river, or cut their own throats, be accounted more guilty of self-murther than this man? My friend adds, without entering into particulars, that he knows another who is in the same case: I have since learnt, that he ended his days in the same manner. “I knew (says Mr. ZIMMERMANN) a man of great genius, and of almost universal knowledge, whom frequent pollutions had reduced to lose all the activity of his understanding, and whose body was exactly in the condition of the patient that consulted Boerhaave[34].” Of this case I shall hereafter take notice. I owe the two following facts to M. RAST, junior, an eminent Physician of Lions, with whom I had the pleasure of passing some months at Montpelier. A young man at Montpelier, a student of physic, perished by his excesses in the practice of self-pollution. His imagination was so horror-struck, that he died in a sort of despair, fancying that he saw hell open, on the side of him, to receive him. A child of that town, not above six or seven years old, taught, I believe, by a servant-maid, practised it so frequently; that a hectic fever coming on, soon cut him off. His fury of passion for this act was so great, that there was no hindering him to the very last days of his life. When it was represented to him that he was hastening his death, his comfort, he said, was, that he should the sooner rejoin his father, who was dead a few months before. M. MIEG, a celebrated physician of Basil, well known in the literary world by some excellent dissertations, and to whom his country is obliged for his introduction of inoculation, of which he continues the practice with great ability and equal success, has communicated to me a letter of the Professor STEHELIN, a name ever dear to literature, in which I have found many interesting and useful observations. Some I reserve for properer places in the course of this work. Here I shall but subjoin two instances. The son of M. ——, aged about fourteen or fifteen years, died of convulsions, and a kind of epilepsy, of which the original cause was self-pollution. In vain was he attended by the most experienced physicians of the town. I also know a young lady of twelve or thirteen years old, who by this execrable practice has drawn upon herself a consumption, together with a timpanous abdomen, the _fluor albus_, and an incontinence of urine. Though medicines have alleviated her complaints, she is still but in a languishing condition, and I dread fatal consequences. SECTION III. _Descriptions taken from the book intitled ONANIA._
