I might continue these quotations indefinitely; but I will not weary you by citing more, and surely, sufficient evidence has already been produced to sustain the allegation that the old system of medicine is unworthy of our confidence; that, with no law upon which to base its principles of treatment, its practice rests upon a chaotic mass of empirical experiences, groundless theories, and ever-changing fancies; that those best acquainted with its principles, and the results of its practice, have the least faith in its usefulness; and that the interests of the suffering, imperiously demand a revolution in the method of treating disease, and call for a system more in harmony with Nature, more reliable in its application, and more successful in its results. This degraded state of the medical practice was deeply felt by HAHNEMANN, and in 1778 he retired from the practice of medicine in disgust at its uncertainties, after having acquired fame as a scientific scholar and high standing in his profession, breaking away from the past and opening a new field of glory to his activities, as well as a new era of progress in the medical art. SAMUEL HAHNEMANN was a great man; the discoverer of the true law of cure, in accordance with the principles and laws of Nature. I need not tell you, that we maintain that this much-desired and long-looked-for law of cure, which is to be a lamp to the feet of the physician, making plain his path, and giving him an unfailing guide in the application of remedies to the removal of disease, not only exists, but has been proclaimed to the world by the immortal Hahnemann in his well-known formula: _Similia Similibus Curantur!_ But who was Samuel Hahnemann? When I say that this great Reformer of Medicine was a regularly educated physician of great learning and unusual general culture and literary attainments, I speak but feeble praise compared with the language of Sir John Forbes, Hahnemann's most learned critic, where he says: "No candid reader of his writings can hesitate for a moment to admit that he was a very extraordinary man; one, whose name will descend to posterity as the exclusive excogitator and founder of an original system of medicine, as ingenious as many that preceded it, and destined to be the remote, if not the immediate cause of more fundamental changes in the practice of the healing art, than have resulted from any promulgated since the days of GALEN himself." And he adds: "He was undoubtedly a man of genius and a scholar, a man of indefatigable industry and of dauntless energy." The great HALLER, says of him: "He is a doublehead of philosophy and wisdom." And HUFELAND, the father of orthodox medicine, speaks of him as one of the most distinguished physicians in Germany, while the late DR. MOTT of New York, after having visited HAHNEMANN in Paris, speaks in the highest terms of his candor, learning and genius.
