. He theorised the existence of a natural energy transference occurring between all animated and inanimate objects; this he called " animal magnetism", sometimes later referred to as ''mesmerism''. Mesmer's theory attracted a wide following between about 1780 and 1850, and continued to have some influence until the end of the 19th century.Crabtree, introduction In 1843, the Scottish doctor James Braid proposed the term " hypnotism" for a technique derived from animal magnetism; today the word "

Animal magnetism

In 1774, Mesmer produced an "artificial tide" in a patient, Francisca Österlin, who suffered from hysteria, by having her swallow a preparation containing iron and then attaching magnets to various parts of her body. She reported feeling streams of a mysterious fluid running through her body and was relieved of her symptoms for several hours. Mesmer did not believe that the magnets had achieved the cure on their own. He felt that he had contributed animal magnetism, which had accumulated in his work, to her. He soon stopped using magnets as a part of his treatment. In the same year Mesmer collaborated with

Paris soon divided into those who thought he was a charlatan who had been forced to flee from Vienna and those who thought he had made a great discovery. In his first years in Paris, Mesmer tried and failed to get either the Royal Academy of Sciences or the

to provide official approval for his doctrines. He found only one physician of high professional and social standing, Charles d'Eslon, to become a disciple. In 1779, with d'Eslon's encouragement, Mesmer wrote an 88-page book, ''Mémoire sur la découverte du magnétisme animal'', to which he appended his famous 27 Propositions. These propositions outlined his theory at that time. Some contemporary scholars equate Mesmer's animal magnetism with the Qi (chi) of Traditional Chinese Medicine and mesmerism with

person, for example, involved causing a fit of madness. The advantage of magnetism involved accelerating such crises without danger.


Procedure

Mesmer treated patients both individually and in groups. With individuals he would sit in front of his patient with his knees touching the patient's knees, pressing the patient's thumbs in his hands, looking fixedly into the patient's eyes. Mesmer made "passes", moving his hands from patients' shoulders down along their arms. He then pressed his fingers on the patient's

region (the area below the diaphragm), sometimes holding his hands there for hours. Many patients felt peculiar sensations or had convulsions that were regarded as crises and supposed to bring about the cure. Mesmer would often conclude his treatments by playing some music on a

. By 1780, Mesmer had more patients than he could treat individually and he established a collective treatment known as the "baquet." An English doctor who observed Mesmer described the treatment as follows:
In the middle of the room is placed a vessel of about a foot and a half high which is called here a "baquet". It is so large that twenty people can easily sit round it; near the edge of the lid which covers it, there are holes pierced corresponding to the number of persons who are to surround it; into these holes are introduced iron rods, bent at right angles outwards, and of different heights, so as to answer to the part of the body to which they are to be applied. Besides these rods, there is a rope which communicates between the baquet and one of the patients, and from him is carried to another, and so on the whole round. The most sensible effects are produced on the approach of Mesmer, who is said to convey the fluid by certain motions of his hands or eyes, without touching the person. I have talked with several who have witnessed these effects, who have convulsions occasioned and removed by a movement of the hand...

took exception to the official reports. He wrote a dissenting opinion that declared Mesmer's theory credible and worthy of further investigation. The commission did not examine Mesmer, but investigated the practice of d'Eslon.

Mesmer was driven into exile soon after the investigations on animal magnetism although his influential student, Armand-Marie-Jacques de Chastenet, Marquis de Puységur (1751–1825), continued to have many followers until his death.
