But to return: It is certainly the case that frequently "the doctor" takes great care not to let the patient know what is the matter, and even not to let him know what he is swallowing. This is because a good many people, if at a critical point of disease, may be made to turn toward health if made to believe that they are doing so, but would be frightened, in the literal sense of the words, to death, if told what a dangerous state they are in. One sort of regular practice humbug is rendered necessary by the demands of the patients. This is giving good big doses of something with a horrid smell and taste. There are plenty of people who don't believe the doctor does anything to earn his money, if he does not pour down some dirty brown or black stuff very nasty in flavor. Some, still more exacting, wish for that sort of testimony which depends on internal convulsions, and will not be satisfied unless they suffer torments and expel stuff enough to quiet the inside of Mount Vesuvius or Popocatepetl. "He's a good doctor," was the verdict of one of this class of leather-boweled fellows--"he'll work your innards for you!" It is a milder form of this same method to give what the learned faculty term a placebo. This is a thing in the outward form of medicine, but quite harmless in itself. Such is a bread-pill, for instance; or a draught of colored water, with a little disagreeable taste in it. These will often keep the patient's imagination headed in the right direction, while good old Dame Nature is quietly mending up the damages in "the soul's dark cottage." One might almost fancy that, in proportion as the physician is more skillful, by so much he gives less medicine, and relies more on imagination, nature, and, above all, regimen and nursing. Here is a story in point. There was an old gentleman in Paris, who sold a famous eye-water, and made much gain thereby. He died, however, one fine day, and unfortunately forgot to leave the recipe on record. "His disconsolate widow continued the business at the old stand," however--to quote another characteristic French anecdote--and being a woman of ready and decisive mind, she very quietly filled the vials with water from the river Seine, and lived respectably on the proceeds, finding, to her great relief, that the eye-water was just as good as ever. At last however, she found herself about to die, and under the stings of an accusing conscience she confessed her trick to her physician, an eminent member of the profession. "Be entirely easy, Madam," said the wise man; "don't be troubled at all. You are the most innocent physician in the world; you have done nobody any harm." It is an old and illiberal joke to compare medicine to war, on the ground that the votaries of both seek to destroy life. It is, however, not far from the truth to say that they are alike in this; that they are both preeminently liable to mistakes, and that in both he is most successful who makes the fewest.
