The numerous writings that appeared between the years 1813 and 1825 show how much attention was excited in France. With every succeeding year some new discovery was put forth, until at last the magnetisers seemed to be very generally agreed that there were six separate and distinct degrees of magnetisation. They have been classed as follow:—

In the first stage, the skin of the patient becomes slightly reddened; and there is a feeling of heat, comfort, and lightness all over the body; but there is no visible action on the senses.

In the second stage, the eye is gradually abstracted from the dominion of the will (or, in other words, the patient becomes sleepy). The drooping eyelids cannot be raised; the senses of hearing, smelling, feeling, and tasting are more than usually excited. In addition, a variety of nervous sensations are felt, such as spasms of the muscles and prickings of the skin, and involuntary twitchings in various parts of the body.

In the third stage, which is that of magnetic sleep, all the senses are closed to external impressions; and sometimes fainting, and cataleptic or apoplectic attacks may occur.

In the fourth stage, the patient is asleep to all the world; but he is awake within his own body, and consciousness returns. While in this state, all his senses are transferred to the skin. He is in the perfect crisis, or magnetic somnambulism; a being of soul and mind—seeing without eyes—hearing without ears, and deadened in body to all sense of feeling.

In the fifth stage, which is that of lucid vision, the patient can see his own internal organisation, or that of others placed in magnetic communication with him. He becomes, at the same time, possessed of the instinct of remedies. The magnetic fluid, in this stage, unites him by powerful attraction to others, and establishes between them an impenetration of thought and feeling so intense as to blend their different natures into one.

In the sixth stage, which is at the same time the rarest and the most perfect of all, the lucid vision is not obstructed by opaque matter, or subject to any barriers interposed by time or space. The magnetic fluid, which is universally spread in nature, unites the individual with all nature, and gives him cognizance of coming events by its universal lucidity.

So much was said and written between the years 1820 and 1825, and so many converts were made, that the magnetisers became clamorous for a new investigation. M. de Foissac, a young physician, wrote to the Academie Royale du Medicine a letter, calling for inquiry, in which he complained of the unfairness of the report of Messrs. Bailly and Franklin in 1784, and stating that, since that time, the science had wholly changed by the important discovery of magnetic somnambulism. He informed the Academy that he had under his care a young woman, whose powers of divination when in the somnambulic state were of the most extraordinary character. He invited the members of that body to go into any hospital, and choose persons afflicted with any diseases, acute or chronic, simple or complex, and his somnambulist, on being put en rapport, or in magnetic connexion, with them, would infallibly point out their ailings and name the remedies. She, and other somnambulists, he said, could, by merely laying the hand successively on the head, the chest, and the abdomen of a stranger, immediately discover his maladies, with, the pains and different alterations thereby occasioned. They could indicate, besides, whether the cure were possible, and, if so, whether it were easy or difficult, near or remote, and what means should be employed to attain this result by the surest and readiest way. In this examination they never departed from the sound principles of medicine. "In fact," added M. de Foissac, "I go further, and assert that their inspirations are allied to the genius which animated Hippocrates!"

In the mean time experiments were carried on in various hospitals of Paris. The epileptic patients at the Salpetriere were magnetised by permission of M. Esquirol. At the Bicetre also the same resuits were obtained. M. de Foissac busied himself with the invalids at the Hospice de la Charite, and M. Dupotet was equally successful in producing sleep or convulsions at Val de Grace. Many members of the Chamber of Deputies became converts, and M. Chardel, the Comte de Gestas, M. de Laseases, and others, opened their saloons to those who were desirous of being instructed in animal magnetism. [Dupotet's Introduction to the Study of Animal Magnetism, page 23.] Other physicians united with M. de Foissac in calling for an inquiry; and ultimately the Academy nominated a preliminary committee of five of its members, namely, Messrs Adelon, Burdin, Marc, Pariset, and Husson, to investigate the alleged facts, and to report whether the Academy, without any compromise of its dignity, could appoint a new commission.

Before this committee, M. de Foissac produced his famous somnambulist; but she failed in exhibiting any one of the phenomena her physician had so confidently predicted: she was easily thrown into the state of sleep, by long habit and the monotony of the passes and manipulations of her magnetiser; but she could not tell the diseases of persons put en rapport with her. The committee of five framed excuses for this failure, by saying, that probably the magnetic fluid was obstructed, because they were "inexperienced, distrustful, and perhaps impatient." After this, what can be said for the judgment or the impartiality of such a committee? They gave at last their opinion, that it would be advisable to appoint a new commission. On the 13th of December 1825, they presented themselves to the Academie to deliver their report. A debate ensued, which occupied three days, and in which all the most distinguished members took part. It was finally decided by a majority of ten, that the commission should be appointed, and the following physicians were chosen its members:—They were eleven in number, viz. Bourdois de la Motte, the President; Fouquier, Gueneau de Mussy, Guersent, Husson, Itard, Marc, J. J. Leroux, Thillay, Double, and Majendie.
