open air in a cool atmosphere; taking frequent and moderate exercise, so that it does not occasion fatigue. Cold bathing is a very important and essential part of the treatment to be observed; the daily use of the _bidet_, or the frequent application of a towel, dipped in cold water, to the testes, applied twice or thrice a day, or the _douche bath_, will be found of much service. To prescribe formulæ for the various temperaments subject to this affection would be to transcribe all the tonics from the pharmacopœia: they are severally useful, but the various preparations of iron surpass all others. During this treatment the state of the mind should not be neglected: no lascivious idea should be for a moment encouraged, nor should the imagination be permitted to wander over the works of fiction or romance in any way connected with matters of love. It not unfrequently happens that patients affected with these complaints are apt to despond, and become miserably depressed in spirits; to remove which, every recreation should be encouraged to prevent them pondering over their own situation, and, if possible, to divert the mind from gloomy ideas: lively and agreeable company should be courted; theatres, concerts, or any other rational amusement consonant with the principles of the patient, should be visited or pursued, and by an uninterrupted perseverance in this mode of treatment for a sufficient length of time, I have seen the most beneficial results arise. The great art and difficulty in treating these cases consist in giving tonics to a certain extent and no further—avoiding excess, whereby we stimulate and produce fever; or depletion, and induce debility. Early hours, fresh air, exercise, attention to diet, the shower bath, topical application of cold, with properly regulated sexual intercourse, are rarely ineffectual in curing the disease. I could narrate many instances wherein the sexual desire declined on the intervention of ordinary illness; any powerful mental solicitude will suffice, but such a cause is commonly remediable. Where the cause is traceable to excesses and pernicious indulgences, if not accompanied by disorganization, hope should not be abandoned; but the patient should not cling to, or hang his reliance upon, hole-and-corner speculators, or their advertised specifics. He should consult men legitimately engaged in the profession, in which, perhaps, more talent and honor are concentrated, than in any other department of science. ON PILES OR HŒMORRHOIDS.
