To the onlooker the situation was rendered additionally piquant by the fact that the boy, at the very time when he was apparently acutely sensitive to pain inflicted upon Mr. Smith, showed no sign of susceptibility when any part of his own person was pretty severely maltreated. The only point in the trials which seems to call for special notice is the failure on two occasions to indicate the seat of pain when the agent's hair was pulled (7 and 21). Numerous trials with the same and other percipients have shown that this particular experiment rarely succeeds, possibly because the pain so caused is with many people not of an acute kind.[29] _Transference of Visual Images._ But when we leave these experiments in the transfer of the less specialised forms of sensation we find that but few observers have paid attention to the phenomena of telepathy in the hypnotic state. Probably this is in some measure due to one or two initial difficulties in conducting experiments on such subjects. Opening the eyes to permit the subject to reproduce a diagram will in many cases have the effect of wakening him. Again, with some persons it is a matter of difficulty to maintain the exact stage of the hypnotic trance when they are quiescent enough for the alien impression to meet with little risk of disturbance from the subject's own mental activities, and yet sufficiently alert to prevent them from relapsing, as was frequently the case with Wells, the percipient just referred to, into a torpid sleep from which no further response could be elicited. But, after all, these difficulties when they occur can readily be overcome by the exercise of a little patience. If the study of thought-transference in the hypnotic state has been comparatively neglected, it is mainly because, as already suggested, with most persons the more salient phenomena of the trance--hallucination, anæsthesia, rigidity, etc.--have distracted attention from what may ultimately prove to be a more fruitful line of inquiry. For the following record we are indebted to Dr. Liébeault, of Nancy, who sent us the account in 1886. No. 12.--By DR. LIÉBEAULT. [The first series of experiments were made on the afternoon of the 10th December 1885, in Dr. Liébeault's house at Nancy. There were present, in addition, Madame S., Dr. Brullard, and Professor Liégeois, who acted as agent, and Mademoiselle M., the subject. The subject was hypnotised by Professor Liégeois, and experiments were made with diagrams, and in two cases the design--a water-bottle (_carafe_) and a table with a drawer and drawer-knob--was reproduced with exactness. Precautions had, of course, been taken to conceal the original design from the percipient. The account of the seventh and last experiment is quoted in full.]
