The touching or stroking practised in mesmeric treatments, as auxiliaries of magnetism, properly so called, required no direct experiments, since the principal agent,—since magnetism itself, had disappeared. Bailly, therefore, confined himself, in this respect, to anatomical and physiological considerations, remarkable for their clearness and precision. We read, also, with a lively interest, in his report, some ingenious reflections on the effects of imitation in those assemblages of magnetized people. Bailly compares them to those of theatrical representations. He says: "Observe how much stronger the impressions are when there are a great many spectators, and especially in places where there is the liberty of applauding. This sign of particular emotions produces a general emotion, participated in by everybody according to their respective susceptibility. This is also observed in armies on the day of battle, when the enthusiasm of courage, as well as panic-terrors, propagate themselves with so much rapidity. The sound of the drum and of military music, the noise of the cannon, of the musquetry, the cries, the disorder, stagger the organs, impart the same movement to men's minds, and raise their imaginations to a similar degree. In this unity of intoxication, an impression once manifested becomes universal; it encourages men to charge, or determines men to fly." Some very curious examples of imitation close this portion of Bailly's report.
The commissioners finally examined whether these convulsions, occasioned by the imagination or by magnetism, could be useful in curing or easing the suffering persons. The reporter said: "Undoubtedly, the imagination of sick people often influences the cure of their maladies very much.... There are cases in which every thing must first be disordered, to enable us to restore order ... but the shock must be unique ... whereas in the public treatment by magnetism ... the habit of the crises cannot but be injurious."
This thought related to the most delicate considerations. It was developed in a report addressed to the king personally. This report was to have remained secret, but it was published some years since. It should not be regretted; the magnetic treatment, regarded in a certain point of view, pleased sick people much; they are now aware of all its dangers.
In conclusion, Bailly's report completely upsets an accredited error. This was an important service, nor was it the only one. In searching for the imaginary cause of animal magnetism, they ascertained the real power that man can exert over man, without the immediate and demonstrable intervention of any physical agent; they established that "the most simple actions and signs sometimes produce most powerful effects; that man's action on the imagination may be reduced to an art ... at least in regard to persons who have faith." This work finally showed how our faculties should be experimentally studied; in what way psychology may one day come to be placed among the exact sciences.
I have always regretted that the commissioners did not judge it expedient to add a historical chapter to their excellent work. The immense erudition of Bailly would have given it an inestimable value. I figure to myself, also, that in seeing the Mesmeric practices that have now been in use during upwards of two thousand years, the public would have asked itself whether so long an interval of time had ever been required to push a good and useful thing forward into estimation. By circumscribing himself to this point of view, a few traits would have sufficed.
Plutarch, for example, would have come to the aid of the reporter. He would have showed him Pyrrhus curing complaints of the spleen, by means of frictions made with the great toe of his right foot. Without giving one's self up to a wild spirit of interpretation, we might be permitted to see in that fact the germ of animal magnetism. I admit that one circumstance would have rather unsettled the savant: this was the white cock that the King of Macedon sacrificed to the gods before beginning these frictions.
Vespasian, in his turn, might have figured among the predecessors of Mesmer, in consequence of the extraordinary cures that he effected in Egypt by the action of his foot. It is true that the pretended cure of an old blindness, only by the aid of a little of that emperor's saliva, would have thrown some doubt on the veracity of Suetonius.
Homer and Achilles are not too far back but we might have invoked their names. Joachim Camerarius, indeed, asserted having seen, on a very ancient copy of the Iliad, some verses that the copyists sacrificed because they did not understand them, and in which the poet alluded, not to the heel of Achilles (its celebrity has been well established these three thousand years,) but to the medical properties possessed by the great toe of that same hero's right foot.
What I regret most is, the chapter in which Bailly might have related how certain adepts of Mesmer's had the hardihood to magnetize the moon, so as, on a given day, to make all the astronomers devoted to observing that body fall into a syncope; a perturbation, by the way, that no geometer, from Newton to Laplace, had thought of.
The work of Bailly gave rise to trouble, spite, and anger, among the Mesmerists. It was for many months the target for their combined attacks. All the provinces of France saw refutations of the celebrated report arise: sometimes under the form of calm discussions, decent and moderate; but generally with all the characteristics of violence, and the acrimony of a pamphlet.
