Proust[8] has published a case of _Automatisme ambulatoire_ with pronounced hysteria which differs from Naef's in the repeated occurrence of the attacks. An educated man, 30 years old, exhibits all the signs of _grande hystérie;_ he is very suggestible, has from time to time, under the influence of excitement, attacks of amnesia which last from two days to several weeks. During these states he wanders about, visits relatives, destroys various objects, incurs debts, and has even been convicted of "picking pockets." Boileau describes a similar case[9] of wandering-impulse. A widow of 22, highly hysterical, became terrified at the prospect of a necessary operation for salpingitis; she left the hospital and fell into a state of somnambulism, from which she awoke three days later with total amnesia. During these three days she had travelled a distance of about 60 kilometres to fetch her child. William James has described a case of an "ambulatory sort."[10] The Rev. Ansel Bourne, an itinerant preacher, 30 years of age, psychopathic, had on a few occasions attacks of loss of consciousness lasting one hour. One day (January 17, 1887) he suddenly disappeared from Greene, after having taken 551 dollars out of the bank. He remained hidden for two months. During this time he had taken a little shop under the name of H. J. Browne in Norriston, Pa., and had carefully attended to all purchases, although he had never done this sort of work before. On March 14, 1887, he suddenly awoke and went back home, and had complete amnesia for the interval. Mesnet[11] publishes the following case:-- F., 27 years old, sergeant in the African regiment, was wounded in the parietal bone at Bazeilles. Suffered for a year from hemiplegia, which disappeared when the wound healed. During the course of his illness the patient had attacks of somnambulism, with marked limitation of consciousness; all the senses were paralysed, with the exception of taste and a small portion of the visual sense. The movements were co-ordinated, but obstacles in the way of their performance were overcome with difficulty. During the attacks he had an absurd collecting-mania. By various manipulations one could demonstrate a hallucinatory content in his consciousness; for instance, when a stick was put in his hand he would feel himself transported to a battle scene, would place himself on guard, see the enemy approaching, etc. Guinon and Sophie Waltke[12] made the following experiments on hysterics:-- A blue glass was held in front of the eyes of a female patient during a hysterical attack; she regularly saw the picture of her mother in the blue sky. A red glass showed her a bleeding wound, a yellow one an orange-seller or a lady with a yellow dress. Mesnet's case reminds one of the cases of occasional attacks of shrinkage of memory. MacNish[13] communicates a similar case.
