542 A. We now come to the effects of hypnotic suggestion in producing certain definite changes in the vaso-motor system, in glands and secretions, etc. I give a few examples in this and the two next Appendices. In the Revue de l'Hypnotisme, September 1891, p. 85, De Jong reports a complete cure achieved by suggestion, of a most desperate case of hæmorrhagy in a boy of nine. The symptoms first appeared when he was eighteen months old. One of his sisters had died of the same disease. The loss of blood, through the nose or through the mouth, occurred irregularly, at intervals sometimes of two months, sometimes of two weeks.

Grasset (in Revue de l'Hypnotisme, November 1887, p. 141) reports some cases in which, by hypnotic suggestion, he arrested loss of blood through the mouth in hysterical patients.

542 B. Dr. Burot in the Revue de l'Hypnotisme, January 1890, p. 197, reports the case of a patient whose arms were contracted by hysterical attacks, the contracture being accompanied by local asphyxia of the hands, which lasted for several weeks. Both hands were swollen and violet in color, and of a temperature far below the normal. The temperature was raised day by day by hypnotic suggestion, which at length cured the asphyxia. At a later stage it recurred, but was found more amenable to treatment. It also appeared that the temperature could be lowered as well as raised by suggestion. The contracture always recurred when the asphyxia was brought back by suggestion.

Professor Beaunis and Dr. Krafft-Ebing have slowed the pulse by hypnotic suggestion,1 and these savants, as well as Professor Bernheim, M. Focachon and others, have produced redness and blisters by the same means. Drs. Mabille, Ramadier, Bourru, Burot, have produced localised hyperæmia, epistaxis, ecchymosis.2 Dr. Forel and others have restored arrested secretions at a precisely fixed hour.3 Dr. Krafft-Ebing has produced a rise of temperature at moments fixed by himself - a rise, for instance, from 370 to 38.50 C.4 Burot has lowered the temperature of a hand as much as 10 C. by suggestion.6 He supposes that the mechanism employed is the constriction of the brachial artery, beneath the biceps. "How can it be," he asks, "that when one merely says to the subject, 'your hand will become cold,' the vaso-motor nervous system answers by constricting the artery to the degree necessary to achieve the result desired? C'est ce qui dépasse notre imagination".

542 C. The following is a summary of a case of the cure of hyper-hydrosis reported by Dr. Bramwell in the British Medical Journal, September 10th, 1898:

Miss B., aged fifteen, January 1890. On the back of the left arm, just above the wrist, a patch of skin 2½ inches long by 1½ broad was the seat of constant perspiration. This had existed from early childhood, was always excessive, and invariably rendered more so by exertion or emotion. The forearm was always enveloped in bandages, but these rapidly became saturated, and the perspiration dripped upon the floor. On January 10th the patient was hypnotised for the first time, and somnambulism induced. By the following day the perspiration had markedly diminished; the patient was again hypnotised, when the perspiration ceased. Two years later there had been no relapse.
