These experiments lasted for about five months. They had hardly commenced, before Mesmer, alarmed at the loss both of fame and profit, determined to return to Paris. Some patients of rank and fortune, enthusiastic believers in his doctrine, had followed him to Spa. One of them named Bergasse, proposed to open a subscription for him, of one hundred shares, at one hundred louis each, on condition that he would disclose his secret to the subscribers, who were to be permitted to make whatever use they pleased of it. Mesmer readily embraced the proposal; and such was the infatuation, that the subscription was not only filled in a few days, but exceeded by no less a sum than one hundred and forty thousand francs.
With this fortune he returned to Paris, and recommenced his experiments, while the royal commission continued theirs. His admiring pupils, who had paid him so handsomely for his instructions, spread his fame over the country, and established in all the principal towns of France, “Societies of Harmony,” for trying experiments and curing all diseases by means of magnetism. Some of these societies were a scandal to morality, being joined by profligate men of depraved appetites, who took a disgusting delight in witnessing young girls in convulsions. Many of the pretended magnetisers were asserted at the time to be notorious libertines, who took that opportunity of gratifying their passions.
At last the commissioners published their report, which was drawn up by the illustrious and unfortunate Bailly. For clearness of reasoning and strict impartiality it has never been surpassed. After detailing the various experiments made, and their results, they came to the conclusion that the only proof advanced in support of animal magnetism was the effects it produced on the human body—that those effects could be produced without passes or other magnetic manipulations—that all these manipulations and passes and ceremonies never produce any effect at all if employed without the patient’s knowledge; and that therefore imagination did, and animal magnetism did not, account for the phenomena.
