"That Dr. M. considered his art of too great importance, and the abuses it might lead to, too dangerous for him at present to make it public; that he must therefore reserve to himself the time of its publication, and mode of introducing it to general use and observation--that he would first take proper measures to initiate or prepare the minds of men, by exciting in them a susceptibility of this great power; and that he would then undertake to communicate his secret gradually, which he meant to do without hope of reward."
Messmer, too politic to part with his secret for so small a premium, had a better prospect in view; and his apparent disinterestedness and hesitation served only to sound an over-curious public, to allure more victims to his delusive practices, and to retain them more firmly in their implicit belief. Soon after this he was easily prevailed upon to institute a private society, into which none were admitted, but such as bound themselves by a vow to perpetual secrecy. These pupils he agreed to instruct in his important mysteries, on condition of each paying him _one hundred louis_. In the course of six months, having had not less than three hundred such pupils, he realized a fortune of _thirty thousand louis_.
It appears, however, that the disciples of Messmer did not adhere to their engagement: we find them separating gradually from their professor, and establishing schools for the propagation of his system, with a view, no doubt, to reimburse themselves for the expenses of their own initiation into the magnetising art. But few of them having understood the terms and mysterious doctrines of their foreign master, every new adept exerted himself to excel his fellow-labourers, in additional explanations and inventions: others, who did not possess, or could not spare the sum of one hundred louis, were industriously employed in attempts to discover the secret, by their own ingenuity; and thus arose a great variety of magnetical sects. At length, however, Messmer's authority became suspected; his pecuniary acquisitions were now notorious, and our _humane and disinterested philosopher_ was assailed with critical and satirical animadversions from every quarter. The fertility of his process for medical purposes, as well as the bad consequences it might procure in a moral point of view, soon became topics of common conversation, and ultimately even excited the apprehensions of government. One dangerous effect of magnetical associations was, that young voluptuaries began to employ this art, to promote their libidinous and destructive designs.
