of the Faculty of Medicine was, in consequence, appointed on the l2th 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.”⁹

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
