Do not such facts as these point, with almost unerring certainty, to the inefficiency of all medical treatment? Do they not almost, if not quite, prove that when we take medicine, properly so called, or receive active medical treatment; we recover in spite of it? Is there any other rational way of accounting for the almost equal success of all sorts of treatment,--allopathic, botanic, homoeopathic, hydropathic, etc.,--when in the hands of good, sound, common sense, and conjoined with good nursing and attendance? Is it not that man is made to live, and is tough, so that it is not easy to poison him to death? But the most remarkable fact of this kind with which I am acquainted, is the case of Isaac Jennings, M.D., now of Ohio. He was educated at Yale College, in Connecticut. During the progress of his education, he served a sort of medical apprenticeship in the family of Prof. Eli Ives, of New Haven. He took his medical degree in 1812, and soon after this commenced the practice of his profession in Trumbull, in Fairfield County. Here, for eight years, he had ample opportunity to apply the principles with which, at the schools, he had been fully indoctrinated. In the summer of 1820, he removed, by special request, to Derby, nine miles from New Haven. Up to his second year in Derby, he pursued the usual, or orthodox, course of practice. The distance from his former field of labor was not so great but that he retained a portion of his old friends in that region. He was also occasionally called to the town of Huntington, lying partly between the two. On meeting one day with Dr. Tisdale, of Bridgeport, an older physician than himself, he said to him, very familiarly, "Jennings, are you aware that we do far less good with our medicine than we have been wont to suppose?" He replied in the affirmative, and observed that he had been inclining to that opinion for some time. "Do you know," added Dr. Tisdale, "that we do a great deal more harm than good with medicine?" Dr. Jennings replied that he had not yet gone as far as that. Dr. Tisdale then proceeded to state many facts, corroborating the opinion he had thrown out concerning the impotency of medicine. These statements and facts were, to the mind of Dr. Jennings, like a nail fastened in a sure place. From this time forth his medical scepticism increased, till he came, at length, to give his doubts the test of experiment. Accordingly, he substituted for his usual medicaments, bread pills and colored water; and for many years--I believe five or six--gave nothing else. The more rigidly he confined himself to these potions, the better he found his success, till his business was so extended, and his reputation so great, as to exclude all other medical men from his own immediate vicinity.
