The following resolutions were agreed to at the first International Congress of Physicians and Jurists on Hypnotism held in Paris, 1889:

'This Congress recognizes the danger of public exhibitions of magnetism and hypnotism, and deeming that the therapeutic application of hypnotism has become a branch of the science of medicine, that its official teaching is the province of psychiatry, votes the following resolutions:

'1. Public exhibitions of hypnotism and magnetism should be forbidden by the administrative authorities in the interest of public hygiene and public morals.

'2. The employment of hypnotism as a curative agent should be subject to the laws and restrictions which regulate medical practice generally.

'3. It is desirable that the study of hypnotism and of its therapeutic application be introduced into the curriculum of medical sciences.'

The following schedule (pp. 394, 395) has been sent to all physicians who have sent in their names as practising hypnotism. The immense practical value of the statistics to be thus collected will be recognized at a glance.

International Statistics of Hypnotic Impressionability and of Suggestive Psycho-Therapeutics.

The following schedule is framed with the object of elucidating the results of hypnotic treatment by comparative statistics.

'a. The proportion of persons who are susceptible to hypnotic influence.

'b. The degree of impressionability and its relation to the age, sex, constitution and temperament of the subject, and the method of hypnotizing adopted.

'c. The value of hypnotic suggestion as a therapeutic agent tested by the amount of success and number of failures, by the duration and completeness of the cures, ameliorations,' etc.

This inquiry is extremely important, because authorities are not agreed on the subject, and we therefore beg our colleagues who use hypnotism either as a means of cure or for scientific investigation to fill in the enclosed papers as completely and carefully as possible.

Please give the degree of hypnotism attained, and for the purpose of classification observe the following definitions and characteristics:

I. Light Sleep. - Feeling of fatigue. The patient's willpower is either unaffected or is only slightly modified. It is often difficult or impossible to open the eyes. The subject on awaking remembers everything that has happened, and does not experience the sensation of having slept.

II. Profound Sleep. - The patient's will is either partially or completely in abeyance. The eyes are generally closed, but sometimes remain open. Memory on awaking is either lost or incomplete, and he feels more or less the sensation of having slept.

III. Somnambulism. - Complete amnesia on awaking, and possibility of realizing hallucinations and other hypnotic and post-hypnotic suggestions.

The sign O signifies the waking state.

Please indicate the method employed by the following signs: a. Method of Braid and Charcot. Physical means. Vivid sensory impressions (light, sound, etc.). Fixation of the eyes with a brilliant object. Pressure on or friction of certain regions of the body (hypnogenic zones). Monotonous sensory impressions, etc.

/3. Method of Liebeault and Bernheim. Suggestion: the method adopted by the school of Nancy.

7. Combined method - a employed systematically in conjunction with β
