brought out, and let the truth be told fearlessly; and this evil, grown now to be so monstrous, will at length yield to our efforts. I have thus far spoken of only one form of quackery—the sale of secret medicines. It appears in various other forms. I shall give some examples of only a few of them. Many empirics have become itinerant lecturers. They, of course, always have something to sell—books, medicines, braces, breathing-tubes, &c. Their lectures are partly, sometimes wholly, gratuitous, which, certainly, looks like being somewhat benevolent. The lectures are made up of some very plain truths, borrowed from some medical works, which, mingled with some popular errors, and spiced with the prevailing ultraism of the present day, in order to make them interesting, are urged upon the audience as being both new and important. A variety of illustrations and analogies, some of which are true and some merely plausible, are made use of to effect the lecturer’s purpose; which is, to convince the audience that he has examined the subject particularly, and is a thorough master of it. If he succeed in doing this, there is a great rush of invalids to his rooms in the intervals of his lectures. His remedies are costly, but his advice is gratuitous; and this is commonly a very successful bait for the poor invalid. He receives a large amount of money from his numerous patients for what cost him but very little. For the time being, he is the great medical lion of the place. But great as he is, when he is once gone, he is gone never to return to that place again: his vocation _there_ is ended. Some of these empirical lecturers have, as a special attraction, one or two lectures particularly for the ladies, to which no gentleman can be admitted; and one or two also for gentlemen, from which the ladies are excluded. I will only say, that in every case in which I have known this to be done, the character of the lectures has been such as no virtuous community should tolerate. Animal magnetism, as applied to medicine, has made quite a figure in the world of quackery. Miss Martineau, and many other people reputed to be very sensible, have been entrapped by this delusion. The magnetized subject, or clairvoyant, who attends the lecturer on this “science,” in his travels, is said to be able to look into the sick, and see exactly what is going on there. If this be so, animal magnetism must be capable of rendering essential aid in investigating disease—more essential, indeed, than any other means which we have at our command; and every physician should have his clairvoyant to attend him in his daily visits. The hits which are sometimes made by clairvoyants, are said to be astonishing; but they are so for precisely the same reason that the hits of the fortuneteller are sometimes truly wonderful. The clairvoyant has ears, and can hear what may be said aloud or in whisper about different invalids; and the magnetizer can hear for her.
