Of course, there are degrees and varieties of quacks, as well as in the character of their announcements. The street-vender of a "magic pain-reliever," who, by dint of talk and manipulation, convinces some credulous sufferer that his rheumatism is banished, is a quack. So are those who advertise such preparations as sarsaparilla, blood-mixtures, and a variety of pills, potions and lozenges too numerous to mention. So also are those marvelous discoverers of "hair restorers," "removers of freckles," and so on. Most of these do little harm beyond lightening the purses of the purchasers, and in some cases the administration of an inert substance, by exciting the victim's imagination, produces a cure. But the great injury, so far as these innoxious preparations are concerned, lies in the fact that they prevent the sufferer from seeking proper professional treatment. Still this class of quacks is rather to be reckoned among swindlers who obtain money under false pretences, than among the _bona fide_ medical quacks that we have in view. The great aim of this pernicious class is to get people in fair, ordinary health to consult them by means of newspaper advertisements, almanacs, pamphlets and circulars filled with details of the character and symptoms of various diseases, scattered broadcast through the land. We will not contaminate our pages in giving samples _in extenso_ of this prurient and abominable literature, but a few of the typical advertisements to be met in even respectable newspapers, can hardly be omitted if the exposure is to be thorough: *MEN ONLY*.
