There are quite a number of such men in New York, and they offer to cure all manner of diseases. Some offer their wares for a small sum, others charge enormous prices. Frequently one of these men will personate half a dozen different characters. The newspapers are full of their advertisements, some of which are really unfit for the columns of a respectable journal. Besides these, they send thousands of circulars, through the mails, to persons in various parts of the country, setting forth the horrors of certain diseases, and offering to cure them for a fixed sum. The circular contains an elaborate description of the symptoms or premonitory signs of these diseases. A very large number of persons, reading these descriptions, really come to the conclusion that they are affected in the manner stated by the quack. So great is the power of the imagination in these cases, that sound healthy men are, sometimes, absolutely led to fancy themselves in need of medical attention. A short conversation with their regular physicians, would soon undeceive them, but they foolishly send their money to the author of the circular in question, and request a quantity of his medicine for the purpose of trying it. The nostrum is received in due time, and is accompanied by a second circular, in which the patient is coolly informed that he must not expect to be cured by one bottle, box, or package, as the case may be, but that five or six, or sometimes a dozen will be necessary to complete the cure, especially if the case is as desperate and stubborn as the letter applying for the medicine seems to indicate. Many are foolish enough to take the whole half dozen bottles or packages, and in the end are no better in health than they were at first. Indeed they are fortunate if they are not seriously injured by the doses they have taken. They are disheartened in nine cases out of ten, and are, at length, really in need of good medical advice. They have paid the quack more money than a good practitioner would demand for his services, and have only been injured by their folly.
