Mesmer now wrote to Marie Antoinette, with the view of securing her influence in obtaining for him the protection of government. He wished to have a chateau and its lands given to him, with a handsome yearly income, that he might be enabled to continue his experiments at leisure, untroubled by the persecution of his enemies. He hinted the duty of governments to support men of science, and expressed his fear, that if he met no more encouragement, he should be compelled to carry his great discovery to some other land more willing to appreciate him. "In the eyes of your Majesty," said he, "four or five hundred thousand francs, applied to a good purpose, are of no account. The welfare and happiness of your people are everything. My discovery ought to be received and rewarded with a munificence worthy of the monarch to whom I shall attach myself." The government at last offered him a pension of twenty thousand francs, and the cross of the order of St. Michael, if he had made any discovery in medicine, and would communicate it to physicians nominated by the King. The latter part of the proposition was not agreeable to Mesmer. He feared the unfavourable report of the King's physicians; and, breaking off the negotiation, spoke of his disregard of money, and his wish to have his discovery at once recognised by the government. He then retired to Spa, in a fit of disgust, upon pretence of drinking the waters for the benefit of his health.
After he had left Paris, the Faculty of Medicine called upon M. D'Eslon, for the third and last time, to renounce the doctrine of animal magnetism, or be expelled from their body. M. D'Eslon, so far from doing this, declared that he had discovered new secrets, and solicited further examination. A royal commission of the Faculty of Medicine was, in consequence, appointed on the 12th of March 1784, seconded by another commission of the Academie des Sciences, to investigate the phenomena and report upon them. The first commission was composed of the principal physicians of Paris; while, among the eminent men comprised in the latter, were Benjamin Franklin, Lavoisier, and Bailly, the historian of astronomy. Mesmer was formally invited to appear before this body, but absented himself from day to day, upon one pretence or another. M. D'Eslon was more honest, because he thoroughly believed in the phenomena, which it is to be questioned if Mesmer ever did, and regularly attended the sittings and performed experiments.
Bailly has thus described the scenes of which he was a witness in the course of this investigation. "The sick persons, arranged in great numbers and in several rows around the baquet, receive the magnetism by all these means: by the iron rods which convey it to them from the baquet—by the cords wound round their bodies—by the connection of the thumb, which conveys to them the magnetism of their neighbours—and by the sounds of a pianoforte, or of an agreeable voice, diffusing the magnetism in the air. The patients were also directly magnetised by means of the finger and wand of the magnetiser moved slowly before their faces, above or behind their heads, and on the diseased parts, always observing the direction of the holes. The magnetiser acts by fixing his eyes on them. But above all, they are magnetised by the application of his hands and the pressure of his fingers on the hypochondres and on the regions of the abdomen; an application often continued for a long time-sometimes for several hours.
"Meanwhile the patients in their different conditions present a very varied picture. Some are calm, tranquil, and experience no effect. Others cough, spit, feel slight pains, local or general heat, and have sweatings. Others again are agitated and tormented with convulsions. These convulsions are remarkable in regard to the number affected with them, to their duration and force. As soon as one begins to be convulsed, several others are affected. The commissioners have observed some of these convulsions last more than three hours. They are accompanied with expectorations of a muddy viscous water, brought away by violent efforts. Sometimes streaks of blood have been observed in this fluid. These convulsions are characterized by the precipitous, involuntary motion of all the limbs, and of the whole body: by the construction of the throat—by the leaping motions of the hypochondria and the epigastrium—by the dimness and wandering of the eyes—by piercing shrieks, tears, sobbing, and immoderate laughter. They are preceded or followed by a state of languor or reverie, a kind of depression, and sometimes drowsiness. The smallest sudden noise occasions a shuddering; and it was remarked, that the change of measure in the airs played on the piano-forte had a great influence on the patients. A quicker motion, a livelier melody, agitated them more, and renewed the vivacity of their convulsions.
"Nothing is more astonishing than the spectacle of these convulsions. One who has not seen them can form no idea of them. The spectator is as much astonished at the profound repose of one portion of the patients as at the agitation of the rest—at the various accidents which are repeated, and at the sympathies which are exhibited. Some of the patients may be seen devoting their attention exclusively to one another, rushing towards each other with open arms, smiling, soothing, and manifesting every symptom of attachment and affection. All are under the power of the magnetiser; it matters not in what state of drowsiness they may be, the sound of his voice—a look, a motion of his hand—brings them out of it. Among the patients in convulsions there are always observed a great many women, and very few men." [Rapport des Commissaires, redige par M. Bailly.—Paris, 1784.]
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 the delusion 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 notorious libertines, who took that opportunity of gratifying their passions. An illegal increase of the number of French citizens was anything but a rare consequence in Strasburg, Nantes, Bourdeaux, Lyons, and other towns, where these societies were established.
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.
This report was the ruin of Mesmer's reputation in France. He quitted Paris shortly after, with the three hundred and forty thousand francs which had been subscribed by his admirers, and retired to his own country, where he died in 1815, at the advanced age of eighty-one. But the seeds he had sown fructified of themselves, nourished and brought to maturity by the kindly warmth of popular credulity. Imitators sprang up in France, Germany, and England, more extravagant than their master, and claiming powers for the new science which its founder had never dreamt of. Among others, Cagliostro made good use of the delusion in extending his claims to be considered a master of the occult sciences. But he made no discoveries worthy to be compared to those of the Marquis de Puysegur and the Chevalier Barbarin, honest men, who began by deceiving themselves before they deceived others.
The Marquis de Puysegur, the owner of a considerable estate at Busancy, was one of those who had entered into the subscription for Mesmer. After that individual had quitted France, he retired to Busancy with his brother to try Animal Magnetism upon his tenants, and cure the country people of all manner of diseases. He was a man of great simplicity and much benevolence, and not only magnetised but fed the sick that flocked around him. In all the neighbourhood, and indeed within a circumference of twenty miles, he was looked upon as endowed with a power almost Divine. His great discovery, as he called it, was made by chance. One day he had magnetised his gardener; and observing him to fall into a deep sleep, it occurred to him that he would address a question to him, as he would have done to a natural somnambulist. He did so, and the man replied with much clearness and precision. M. de Puysegur was agreeably surprised: he continued his experiments, and found that, in this state of magnetic somnambulism, the soul of the sleeper was enlarged, and brought into more intimate communion with all nature, and more especially with him, M. de Puysegur. He found that all further manipulations were unnecessary; that, without speaking or making any sign, he could convey his will to the patient; that he could, in fact, converse with him, soul to soul, without the employment of any physical operation whatever!
