Mr. Piddington, the secretary of the Society, said that he
considered that these were the most important expe- riments in telepathy which the Society had ever had. We agree with him. The Society has at last succeeded in eliminating simultaneously all question of fraud and all question of mal-observation. Thus, the " facts " them- selves have to be admitted, and the investigator is driven back on to an explanation by means of some hitherto unguessed at law of physics. Mr. Haldane, in a letter to the Times, takes the view that the transmission was by ordinary sound waves ; that is, that Professor Murray was in a state of" hyper-aesthesia " by which his auditory system was rendered so sensitive that it could record words spoken in an ordinary voice in another room at the other end of the house. This is indicated, Mr. Haldane points out, by two factors :— " In the first place, no transmission at all occurs unless the information is spoken. In the second place, mistakes by the subject are very evidently such as arise from imperfect hearing:, Professor Murray, Mr. Haldane adds, is inclined to take -this view of the phenomena himself.
