We have just given some of the amusing experiments that may be performed with subjects in one of the minor stages of hypnotism. But there are other stages which give entirely different manifestations. For a scientific classification of these we are indebted to Professor Charcot, of the Salpetriere hospital in Paris, to whom, next to Mesmer and Braid, we are indebted for the present science of hypnotism. He recognized three distinct stages—lethargy, catalepsy and somnambulism. There is also a condition of extreme lethargy, a sort of trance state, that lasts for days and even weeks, and, indeed, has been known to last for years. There is also a lighter phase than somnambulism, that is called fascination. Some doctors, however, place it between catalepsy and somnambulism. Each of these stages is marked by quite distinct phenomena. We give them as described by a pupil of Dr. Charcot. LETHARGY. This is a state of absolute inert sleep. If the method of Braid is used, and a bright object is held quite near the eyes, and the eyes are fixed upon it, the subject squints, the eyes become moist and bright, the look fixed, and the pupils dilated. This is the cataleptic stage. If the object is left before the eyes, lethargy is produced. There are also many other ways of producing lethargy, as we have seen in the chapter “How to Hypnotize.” One of the marked characteristics of this stage of hypnotism is the tendency of the muscles to contract, under the influence of the slightest touch, friction, pressure or massage, or even that of a magnet placed at a distance. The contraction disappears only by the repetition of that identical means that called it into action. Dr. Courmelles gives the following illustration: “If the forearm is rubbed a little above the palm of the hand, this latter yields and bends at an acute angle. The subject may be suspended by the hand, and the body will be held up without relaxation, that is, without returning to the normal condition. To return to the normal state, it suffices to rub the antagonistic muscles, or, in ordinary terms, the part diametrically opposed to that which produced the phenomenon; in this case, the forearm a little above the hands. It is the same for any other part of the body.” The subject appears to be in a deep sleep, the eyes are either closed or half closed, and the face is without expression. The body appears to be in a state of complete collapse, the head is thrown back, and the arms and legs hang loose, dropping heavily down. In this stage insensibility is so complete that needles can be run into any part of the body without producing pain, and surgical operations may be performed without the slightest unpleasant effect.
