In cases of indiscretion, the quack treatment is always with mercury--notwithstanding denials. Sometimes serious mercurial poisoning results, and not unfrequently, through the charlatan's ignorance of proper treatment in complicated diseases, irreparable injury ensues. The quack advertisements and pamphlets are the source of incalculable evils to youths between the ages of seventeen and thirty. They are impelled by fear to visit the quack's den, where they are "played" as long as practicable. Sometimes exciting drugs, like cantharides, are given in the medicine, and thus intensify the evil. The quack, of course, ascribes the result to the patient's alarming condition, who is growing worse, in spite of his medicines, and who can only be cured by more powerful and costly drugs. Sometimes a seemingly candid but equally misleading offer of "no cure no pay" is offered. In this case the patient is usually required to sign a statement of his condition, in which his symptoms and his previous bad habits are fully set forth. It is stipulated that the "doctor" is to be paid a certain round sum when a cure is effected, and while the case is under treatment the patient pays for the medicines. If no pay is asked for the "stuff," the quack is seldom or ever a loser. Such a document few persons, with characters to lose, would care to run the risk of publishing, and hence they generally acknowledge themselves cured, or pay the doctor handsomely to redeem the document. While wading through this dark morass of deception and fraud, the "anatomical museums" must not be overlooked. These Priapean establishments, in which is an exhibition of wax models of different organs and parts of the human body, are too vile for description. "Lectures" are delivered with the design of furnishing patients to the quack practitioners in whose interest the place is run. Thousands--we might have said millions--of copies of disgusting little books on "Marriage," or the "Philosophy of Marriage," or some cognate obscenity are distributed gratis, and it is no unusual sight to see a score of nervous, hollow-eyed patients waiting for treatment.
