Dr. Baillie, one of the physicians in the great Hotel Dieu of Paris, invited two Homoeopathic practitioners to experiment in his wards. One of these was Curie, now of London, whose works are on the counters of some of our bookstores, and probably in the hands of some of my audience. This gentleman, whom Dr. Baillie declares to be an enlightened man, and perfectly sincere in his convictions, brought his own medicines from the pharmacy which furnished Hahnemann himself, and employed them for four or five months upon patients in his ward, and with results equally unsatisfactory, as appears from Dr. Baillie's statement at a meeting of the Academy of Medicine. And a similar experiment was permitted by the Clinical Professor of the Hotel Dieu of Lyons, with the same complete failure. But these are old and prejudiced practitioners. Very well, then take the statement of Dr. Fleury, a most intelligent young physician, who treated homoeopathically more than fifty patients, suffering from diseases which it was not dangerous to treat in this way, taking every kind of precaution as to regimen, removal of disturbing influences, and the state of the atmosphere, insisted upon by the most vigorous partisans of the doctrine, and found not the slightest effect produced by the medicines. And more than this, read nine of these cases, which he has published, as I have just done, and observe the absolute nullity of aconite, belladonna, and bryonia, against the symptoms over which they are pretended to exert such palpable, such obvious, such astonishing influences. In the view of these statements, it is impossible not to realize the entire futility of attempting to silence this asserted science by the flattest and most peremptory results of experiment. Were all the hospital physicians of Europe and America to devote themselves, for the requisite period, to this sole pursuit, and were their results to be unanimous as to the total worthlessness of the whole system in practice, this slippery delusion would slide through their fingers without the slightest discomposure, when, as they supposed, they had crushed every joint in its tortuous and trailing body. 3. I have said, that to show the truth of the Homoeopathic doctrine, as announced by Hahnemann, it would be necessary to show, in the third place, that remedies never cure diseases when they are not capable of producing similar symptoms! The burden of this somewhat comprehensive demonstration lying entirely upon the advocates of this doctrine, it may be left to their mature reflections.
