The genital organs may, from too much excitement, lose their sensibility, and waste. The manipulations, which at first were followed with the desired result, become unable to excite the genital sense. They may sometimes cause the erection of the penis, and even excite a painful or inconvenient priapism; but they cannot renew the fountain of enjoyment. The remembrance of past pleasures remains; and the onanist, disturbed by their recollection, torments his blunted organs. Obtaining no satisfaction from the modes formerly employed, he now resorts to others, which are sometimes dreadful. His hand which is now armed with some instrument, no longer confines itself to the surface: the surface no longer feels. He now ventures inside, and shrinks from nothing. This continues until these dangerous resources fail, which happens, because they also lose their effect, or because of the severe accidents with which they are sometimes attended. The following case from Chopart, on diseases of the urinary passages, shows the almost incredible extent of insensibility which the penis may attain, or of delirium which may affect a man, who, having exhausted his faculties by excesses, still remains a slave to his passions:-- “A shepherd of Languedoc, Gabriel Gallien, about the age of fifteen, became addicted to onanism, and to such a degree, as to practise it seven or eight times in a day. Emission became at last so difficult, that he would strive for an hour, and then discharge only a few drops of blood. At the age of six and twenty, his hand became insufficient: all he could do, was to keep the penis in a continual state of priapism. He then bethought himself of tickling the internal part of his urethra, by means of a bit of wood, six inches long; and he would spend in that occupation several hours, while tending his flocks in the solitude of the mountains. By a continuation of this titillation for sixteen years, the canal of the urethra became hard, callous, and insensible. The piece of wood then became as ineffectual as his hand. At last, after much fruitless effort, G., one day in despair, drew from his pocket a blunt knife, and made an incision into his glands, along the course of the urethra. This operation, which would have been painful to any body else, was, in him, attended with a sensation of pleasure, followed by a copious emission. He had recourse to his new discovery every time his desire returned. When, after an incision into the cavernous bodies, the blood flowed profusely, he stopped the hemorrhage, by applying around the penis a pretty tight ligature. At last, after repeating the same process, perhaps a thousand times, he ended in splitting his penis into two equal parts, from the orifice of the penis to the stratum, very near to the symphisis pubis. When he had got so far, unable to carry his incision any farther, and again reduced to new privations, he had recourse to a piece of wood, shorter
