hysteria on the same days of the preceding year. Her mother's diary which was unknown to the patient proved the faultless accuracy of the reproduction. Another patient, partly in hypnosis and partly in spontaneous attacks, went through with a hallucinatory distinctness all experiences of a hysterical psychosis which she passed through ten years before and for the greatest part of which she was amnesic until its reappearance. She also showed with surprising integrity and sentient force some etiologically important memories of fifteen to twenty-five years' duration which on their return acted with the full affective force of new experiences.
The reason for this we can only find in the fact that in all the aforesaid relations these memories assume an exceptional position in reference to disappearance. It was really shown that these memories correspond to traumas which were not sufficiently ab-reacted to ("abreagirt "). On closer investigation of the reasons for this prevention we can find at least two series of determinants through which the reaction to the trauma was discontinued.
To the first group we add those cases in which the patient has not reacted to psychic traumas because the nature of the trauma precluded a reaction as in the case of an irremediable loss of a beloved person or because social relations made the reaction impossible, or because it concerned things which the patient wishes to forget and which he therefore intentionally inhibited and repressed from his conscious memory. It is just those painful things which in the hypnotic state are found to be the basis of hysterical phenomena (hysterical delirium of saints, nuns, abstinent women, and well-bred children).
The second series of determinants is not conditioned by the content of the memories but by the psychic states with which the corresponding experiences in the patient have united. As a cause of hysterical symptoms one really finds in hypnosis presentations which are insignificant in themselves but which owe their preservation to the fact that they originated during a severe paralyzing affect like fright or directly in abnormal psychic conditions, as in the semi-hypnotic dreamy states of reveries, in auto-hypnosis and similar states. Here it is the nature of these conditions which makes a reaction to the incident impossible.
