For silent thought transference occasionally

electrical contrivances are resorted to. These are placed in different parts of the hall, and when being pressed by the foot or hand of the agent will convey a message to a certain part of the stage upon which the percipient (who may be blindfolded) rests his foot.

There is another silent method which can be worked by a confederate who is placed behind a curtain close to the chair on the stage upon which the blindfolded percipient sits. The confederate watches the performer who stands amongst the audience and reads through a spyglass what he is writing on his tablet when putting down what members of the audience wish to be done. The confederate then communicates the contents of the writing to the percipient on the stage by whispering or by an electrical apparatus. The position of the performer or agent while he is writing in a clear hand on his tablets with his back to the stage easily enables a confederate to read the writing.

Then there is the silent method of a French conjurer, some of whose performances I have witnessed, which consists of suggesting or "forcing" the spectators to do certain things,

each action having a corresponding number which he conveys to his lady assistant, who is blindfolded, by touching her foot with his after she has come down from the stage and stands by his side amongst the audience.

The "time-coding" method consists of silently counting by the agent and percipient at the same rate, starting from a preconcerted signal and ending at another preconcerted signal. The performer amongst the audience has in his hand a piece of paper on which is written the number that he wishes to silently convey to the other blindfolded performer on the stage. At the moment that he bends his head to look at the number he begins silently counting at a certain rate; a confederate behind the scenes begins counting at the same rate from the moment that the performer bends his head. When the performer lifts his head he ceases counting, so does the confederate. Each number written on the paper is thus conveyed, and the confederate communicates the total to the blindfolded performer by means of an electrical apparatus or otherwise.

I have attended several performances in public halls in London at which thought transference—so-called—was carried out by the above trick methods.

Sir Oliver Lodge was present with me at one of the performances at which the time-coding method was used. He has sent me the following note:—

"I was with Mr. Baggally on one of these occasions, and took note of the fact that he could often guess what was being transmitted by the performers quite as well as they could themselves. We sat in a box looking at them, and he often told me before they had spoken what they were going to say (or words to that effect).
