But enough of this. The reader, I trust, has had a sufficient insight into Homœopathic observation, to see that it proves nothing. If it proves what it professes to do, then anything may be made to prove anything that may be desired. We laugh at the folly of the fly on the coach, that supposed itself to be the cause of all the dust made by the prancing horses, and the whirling wheels; but the folly of the fly is as nothing, compared with his, who considers all symptoms, bodily and mental, for fifty days as resulting from a few decillionths of a grain of sulphur, or salt, or oystershell. And yet it is upon such ridiculous assumptions as these, falsely called “observations,” that the system of Homœopathy is based. The results of these observations, we are informed in Dr. Hering’s introduction, “have, through the zeal of the Homœopathists, already filled more than _fifteen_ octavo volumes.” The Materia Medica of Hahneman himself fills six volumes. It is spoken of by his followers as “a rich arsenal, from which Homœopathy may arm itself against every known disease; it contains at present nearly 80,000 combinations of symptoms, with the corresponding substances which shall produce their counterparts; and it goes on every day to be still farther enriched, and to such an extent, as to leave it utterly impossible to assign any limits to the future developments of Homœopathy.” What a stupendous monument of human folly is this confused mass of rubbish! It is no wonder that a man who could invent such a system as Homœopathy is, should at last place as a cap stone upon this monument the grand discovery, which he says it cost him twelve years of research to make, viz. that seven eighths of all chronic diseases come from a _psoric_ virus, of which psora (vulgarly called itch) is only the simplest development! But it is said that, laugh as we may at the ridiculousness of Homœopathy, as a system, it is really successful in practice. If we are to take the testimony of such observers as Mr. Jahr, and his brother compilers of the fifteen octavo volumes of “observations” to this point, I must beg leave to demur. But the doctors who practice according to these same fifteen octavo volumes, and the multitudes, especially the _female_ multitudes, who practice in their families with their little boxes filled with little phials of little globules, with a little pamphlet of directions, testify, that Homœopathy is eminently successful. Such _was_ the testimony also in regard to the success of Perkins’ Tractors, Dr. Beddoes’ Gases, and St. John Long’s Liniment. That testimony does not avail just now, and I suspect that some years hence, when some other delusion shall succeed in supplanting Homœopathy, the present testimony of Homœopathists to its success will avail as little.
