A young man of rich family, and who had arrived at puberty, consulted this physician, avowing, that from the time he was ten years old, he had enjoyed frequent intercourse with young girls, who had excited him by their lascivious touches; adding, that from this period the power of erection had disappeared. He had travelled for a long time, and had received advice from several French physicians. He went to the Spa waters, and there his case was examined by Van-Hers. The sensibility and weakness of the genital organs were so great, that on the slightest touch, and without any desire for coition, or any sensation, there was a discharge similar to thin milk. This excretion continued both night and day, whenever he passed urine, or on the least rubbing of his shirt. A great many remedies had already been tried. Van-Hers regarded the disease as incurable, but the young man would not listen to his advice; and being very rich, he continued to travel in Italy, France, England, and Germany, in the hope of recovering his lost virility. He consulted many physicians. He then had recourse to quacks; and even tried the powers of magic: but all in vain. After six years of travel, he returned to Van-Hers, regretting that he had not taken his advice. The young man then returned home, deploring the advantages of a large fortune, which rendered him the victim of a precocious abuse of pleasure, of a kind of premature depravity. Wichmann’s dissertation was but little known in France, when Sainte Marie undertook its translation; and not only this, but added many important notes, which have shed new light on diurnal pollution. Wichmann had said, as we have seen, that patients affected with this disease _ejaculated_ the semen. This expression was inexact, and has been rectified by M. Sainte Marie. The patients (said he) do not ejaculate the semen; but it runs away from them: it is not emitted with force. The characters which it presents had briefly been alluded to by Wichmann: his translator has stated them more clearly. According to him, the semen which runs away in diurnal pollution is paler, thinner, and more watery, than that which escapes when the act is attended with pleasure. Its odor, also, is fainter; and the stains it leaves on the linen are slight, superficial, and not very apparent. Wichmann had admitted the existence of a discharge from the prostate gland, which ought not to be confounded with diurnal pollution. Sainte Marie has attempted to point out the characteristics of this discharge. Those in whom it exists, (says he,) find the glans moistened in the morning when they rise with an unctuous substance: if they then compress the urethra from the root to the end of the penis, they press out some drops of a greenish, gluish, and slightly fetid fluid. They thus lose a little of this fluid after indulging in desires, or after erections which have not been followed by the act of venery. Sainte Marie considers it as
