It is well known that Doctor Holmes detests the habit of drugging practised by so many physicians of the "old school," and in his address before the Massachusetts Medical Society, entitled Currents and Counter Currents in Medical Science, he makes a severe attack upon the inordinate use of medicines.

"What is the honest truth," he says at another time, "about the medical art? By far the largest number of diseases which physicians are called to treat will get well at any rate, even in spite of reasonably bad treatment. Of the other fraction, a certain number will inevitably die, whatever is done: there remains a small margin of cases where the life of the patient depends on the skill of the physician. Drugs now and then save life; they often shorten disease and remove symptoms; but they are second in importance to food, air, temperature, and the other hygienic influences. That was a shrewd trick of Alexander's physician on the occasion of his attack after bathing. He asked three days to prepare his medicine. Time is the great physician as well as the great consoler. Sensible men in all ages have trusted most to nature."

Of quacks and other humbugs, Doctor Holmes had an undisguised, wholesome contempt.

"Shall we try," he says, "the medicines advertised with the certificates of justices of the peace, of clergymen, or even members of Congress? Certainly, it may be answered, any one of them which makes a good case for itself. But the difficulty is, that the whole class of commercial remedies are shown by long experience, with the rarest exceptions, to be very sovereign cures for empty pockets, and of no peculiar efficacy for anything else. You may be well assured that if any really convincing evidence was brought forward in behalf of the most vulgar nostrum, the chemists would go at once to work to analyze it, the physiologists to experiment with it, and the young doctors would all be trying it on their own bodies, if not on their patients. But we do not think it worth while, as a general rule, to send a Cheap Jack's gilt chains and lockets to be tested for gold. We know they are made to sell, and so with the pills and potions.... Think how rapidly any real discovery is appropriated and comes into universal use. Take anæsthetics, take the use of bromide of potassium, and see how easily they obtained acceptance. If you are disposed to think any of the fancy systems has brought forward any new remedy of value which the medical profession has been slow to accept, ask any fancy practitioner to name it. Let him name one,—the best his system claims,—not a hundred, but one. A single new, efficient, trustworthy remedy which the medical profession can test as they are ready to test before any scientific tribunal, opium, quinine, ether, the bromide of potassium. There is no such remedy on which any of the fancy practitioners dare stake his reputation. If there were, it would long ago have been accepted, though it had been flowers of brimstone from the borders of Styx or Cocytus."

Homœopathy is classed by Doctor Holmes among such "Kindred Delusions" as the Royal Cure for the King's Evil, the Weapon Ointment, the Sympathetic Powder, the Tar-water mania of Bishop Berkeley, and the Metallic Tractors, or Perkinsism.

In making a direct attack upon the pretentions of Homœopathy, Doctor Holmes declares at the outset that he shall treat it not by ridicule, but by argument; with great freedom, but with good temper and in peaceable language.

Similia similibus curantur. Like cures like, is one of the fundamental principles of Homœopathy, and "improbable though it may seem to some," says Doctor Holmes with his usual impartial fairness, "there is no essential absurdity involved in the proposition that diseases yield to remedies capable of producing like symptoms. There are, on the other hand, some analogies which lend a degree of plausibility to the statement. There are well-ascertained facts, known from the earliest periods of medicine, showing that under certain circumstances, the very medicine which from its known effects, one would expect to aggravate the disease, may contribute to its relief. I may be permitted to allude, in the most general way, to the case in which the spontaneous efforts of an over-tasked stomach are quieted by the agency of a drug which that organ refuses to entertain upon any terms. But that every cure ever performed by medicine should have been founded upon this principle, although without the knowledge of a physician, that the Homœopathy axiom is, as Hahnemann asserts, "the sole law of nature in therapeutics," a law of which nothing more than a transient glimpse ever presented itself to the innumerable host of medical observers, is a dogma of such sweeping extent and pregnant novelty, that it demands a corresponding breath and depth of unquestionable facts to cover its vast pretensions."

Among the many facts of which great use has been made by the Homœopathists, is that found in the precept given for the treatment of parts which have been frozen, by friction with snow, etc.
