Prof. Henry Sidgwick, Trinity College, Cambridge, was President; Prof. W. F. Barrett, F. R. S. E., Royal College of Science, Dublin, and Prof. Balfour Stewart, F. R. S., Owens College, Manchester, were Vice-Presidents, and among the members were a large number of well-known names of Fellows of various learned and royal societies, professional men, and members of Parliament, altogether giving character to the society, as well as assuring sensible methods in its work. Among the subjects first taken up for examination and, so far as possible, for experimental study, were the following:—
(1) Thought-transference, or an examination into the nature and extent of any influence which may be exerted by one mind upon another, apart from any generally recognized mode of perception or communication.
(2) The study of hypnotism and the forms of so-called mesmeric trance.
(3) An investigation of well-authenticated reports regarding apparitions and disturbances in houses reputed to be haunted.
(4) An inquiry into various psychical phenomena commonly called Spiritualistic.
The first report made to the society was concerning thought-reading, or thought-transference, and was a description of various experiments undertaken with a view to determine the question whether one person or one mind can receive impressions or intelligence from another person or mind without communication by word, touch, or sign, or by any means whatsoever apart from the ordinary and recognized methods of perception, or the ordinary channels of communication.
What is meant by thought-transference is perhaps most simply illustrated by the common amusement known as the “willing game”; it is played as follows:—
The person to be influenced or “willed” is sent out of the room; those remaining then agree upon some act which that person is to be willed to accomplish; as, for instance, to take some particular piece of bric-à-brac from a table or cabinet and place it upon the piano, or to find some article which has been purposely hidden. The person to be willed is then brought back into the room; the leader of the game places one hand lightly upon her shoulder or arm, and the whole company think intently upon the act agreed upon in her absence. If the game is successful, the person so willed goes, with more or less promptness, takes the piece of bric-à-brac thought of, and places it upon the piano, as before agreed upon by the company, or she goes with more or less directness and discovers the hidden article. Nervous agitation, excitement, even faintness or actual syncope, are not unusual accompaniments of the effort on the part of the person so willed, circumstances which at least show the unusual character of the performance and also the necessity for caution in conducting it.
If the game is played honestly, as it generally is, the person to be willed, when she returns to the room, is absolutely ignorant of what act she is expected to perform, and the person with whom she is placed in contact does not intentionally give her any clue or information during the progress of the game.
In the more formal experiments the person who is willed is known as the sensitive, subject, or percipient; the person who conducts the experiment is known as the agent or operator. The sensitive is presumed to receive, in some unusual manner, from the minds of the agent and the company, an impression regarding the action to be performed, without communication between them in any ordinary manner.
