If it be said that this is the result of change of fashion merely, and that it therefore does not prove that this practice was not successful, I reply that, though fashion in medicine may sometimes temporarily prevent the use of a good remedy, it never effects the entire and continued abandonment of it by medical men. You will find it always true of remedies and modes of practice which are really valuable, that though they may not be as fashionable after a while, as they were when first introduced into notice, and may, from the fact, that they have been estimated too highly, be for a time undervalued, they will never be wholly given up by the profession. Nearly as great stories were told about calomel and digitalis at first, as were told about the gases of Dr. Beddoes. But while experience has shown that calomel and digitalis were over estimated, it has proved that these gases had an entirely false estimate put upon their remedial powers. It is thus that the medical profession, corrects by experience the errors into which it is led by the uncertainty of medical science. But the community at large pursue a very different course. They never correct their errors, but only supplant one error by introducing another. While physicians reject what is found by experience to be valueless, and retain what is truly valuable, the multitude reject alike the good and the bad, in making their constant changes from remedy to remedy, and from system to system. It is mere caprice, and not a careful discrimination, that leads them to throw aside one favorite medicine or system, and adopt another. It is amusing to watch the movements of the community in relation to quack medicines. Of these there are a multitude constantly appealing to the credulity of the public. Some of them in some way, acquire a currency above their fellows, and from the extent to which they are used, and from the tales of their wonder-working from all quarters of the land, and from all conditions of life, one would suppose that these remedies would never go out of use until mankind cease to be sick. But look again, only a few years after, and these vaunted medicines have gone out of use, and the flaming advertisements proclaiming their virtues have disappeared, and other remedies have taken their places in the public mind, and on the public tongue, and of course in the public stomach. This process of change in the prominent remedies before the public, has ever been going on. Take a single example. A few years ago, almost every invalid was swallowing the Hygeian pills, from the pauper that purchased them with his begged pittance, up to lords and ladies, and senators, and generals, and clergymen. But in a short time, Brandreth’s effulgent glory burst upon the earth, and the Hygeian orb faded, and glimmered, and sunk to rise no more. And now Brandreth is rapidly on the decline, giving way to others who are rising to take his place.
