First let us quote what is said of hypnotism in Foster’s Encyclopedic Medical Dictionary. The dictionary states the derivation of the word from the Greek word meaning sleep, and gives as synonym “Braidism”. This definition follows: “An abnormal state into which some persons may be thrown, either by a voluntary act of their own, such as gazing continuously with fixed attention on some bright object held close to the eyes, or by the exercise of another person’s will; characterized by suspension of the will and consequent obedience to the promptings of suggestions from without. The activity of the organs of special sense, except the eye, may be heightened, and the power of the muscles increased. Complete insensibility to pain may be induced by hypnotism, and it has been used as an anaesthetic. It is apt to be followed by a severe headache of long continuance, and by various nervous disturbances. On emerging from the hypnotic state, the person hypnotized usually has no remembrance of what happened during its continuance, but in many persons such remembrance may be induced by ‘suggestion’. About one person in three is susceptible to hypnotism, and those of the hysterical or neurotic tendency (but rarely the insane) are the most readily hypnotized.” First we will quote the directions for producing hypnotism given by Dr. James R. Cocke, one of the most scientific experimenters in hypnotism in America. His directions of are special value, since they are more applicable to American subjects than the directions given by French writers. Says Dr. Cocke: “The hypnotic state can be produced in one of the following ways: First, command the subject to close his eyes. Tell him his mind is a blank. Command him to think of nothing. Leave him a few minutes; return and tell him he cannot open his eyes. If he fails to do so, then begin to make any suggestion which may be desired. This is the so-called mental method of hypnotization. “Secondly, give the subject a coin or other bright object. Tell him to look steadfastly at it and not take his eyes away from it. Suggest that his eyelids are growing heavy, that he cannot keep them open. Now close the lids. They cannot be opened. This is the usual method employed by public exhibitors. A similar method is by looking into a mirror, or into a glass of water, or by rapidly revolving polished disks, which should be looked at steadfastly in the same way as is the coin, and I think tires the eyes less. “Another method is by simply commanding the subject to close his eyes, while the operator makes passes over his head and hands without coming in contact with them. Suggestions may be made during these passes.
