The first experiments of the kind were conducted on our friend Mr. Sidney Beard, who was for some time an Associate of the Society and took an active interest in its work. Mr. Beard, who was easily hypnotised, would be entranced by Mr. Smith, and sit in a chair with closed eyes. Then, to quote the account of a single experiment, a list of twelve _Yeses_ and _Noes_ in arbitrary order was written by one of ourselves and put into Mr. Smith's hand, with directions that he should successively will the subject to respond or not to respond, in accordance with the list. A tuning-fork was then struck and held at Mr. Beard's ear, and the question, "Do you hear?" was asked by one of ourselves. This was done twelve times in succession, Mr. Beard answering or failing to answer on each occasion in accordance with the "yes" or "no" of the written list--that is to say, with the silent will of the agent. Similar trials on other occasions with Mr. Beard were equally successful. The percipient's own account of the matter is as follows: "During the experiments of January 1st [1883], when Mr. Smith mesmerised me, I did not lose consciousness at any time, but only experienced a sensation of total numbness in my limbs. When the trial as to whether I could hear sounds was made I heard the sounds distinctly each time, but in a large number of instances I felt totally unable to acknowledge that I heard them. I seemed to know each time whether Mr. Smith wished me to say that I heard them; and as I had surrendered my will to his at the commencement of the experiment, I was unable to reassert my power of volition whilst under his influence."

Further trials of the same kind were carried on in November 1883 by Professor Barrett, at his own house in Dublin. The hypnotist and agent was again Mr. G. A. Smith, the percipient a youth named Fearnley, a stranger to Mr. Smith. In the first series of trials Professor Barrett asked Fearnley, "Now will you open your hand?" at the same time pointing to "Yes" or "No," written on a card, and held in sight of Mr. Smith, but out of view from the percipient. Mr. Smith, who was not in contact with the subject, directed his silent will in accordance with the written indication. In twenty experiments conducted under these conditions there were only three failures. Later, to quote Professor Barrett,
