1. Automatic Movements of the Table.—Before the patient came under my observation she had been influenced by the suggestion of “table-turning” which she had first come across as a game. As soon as she entered the circle there appeared communications from members of her family which showed her to be a medium. I could only find out that as soon as ever her hand was placed on the table, the typical movements began. The resulting communications have no interest for us. But the automatic character of the act itself deserves some discussion, for we may, without more ado, set aside the imputation that there was any question of intentional and voluntary pushing or pulling on the part of the patient.
As we know from the investigations of Chevreul,[1] Gley, Lehmann and others, unconscious motor phenomena are not only of frequent occurrence among hysterical persons, and those pathologically inclined in other directions, but they are also relatively easily produced in normal persons who show no other spontaneous automatisms. I have made many experiments on these lines, and can confirm this observation. In the great majority of instances all that is required is enough patience to put up with an hour of quiet waiting. In most subjects motor automatisms will be obtained in a more or less high degree if contra-suggestions do not intervene as obstacles. In a relatively small percentage the phenomena arise spontaneously, i.e. directly under the influence of verbal suggestion or of some earlier auto-suggestion. In this instance the case is powerfully affected by suggestion. In general the particular predisposition is subject to all those laws which also hold good for normal hypnosis. Nevertheless certain special circumstances are to be taken into account, conditioned by the peculiarity of the case. It is not a question of a total hypnosis, but of a partial one, limited entirely to the motor area of the arm, like the cerebral anæsthesia produced by “magnetic passes” for a painful spot in the
