(_Proc. Soc. Psych. Research_, vol. v. pp. 142, 143.) In this case it will be observed that P. alone was in possession of the knowledge, without which all the efforts of those at the table could have produced only a meaningless sequence of letters. In some other experiments of the series the procedure was more complicated. M. Richet, standing apart from both tables, asked a question, the answer to which was given by the percipients with a certain approximation to correctness. The results, though less striking than those already quoted, are yet such as to suggest that they were not due to chance.[55] _Production of Local Anæsthesia._ We now pass to experiments of another kind, resembling those last quoted, inasmuch as the effects were produced without the consciousness of the percipient, but differing in the important particular that no deliberate and conscious effort on his part could have enabled him to produce them. In experiments carried on with various subjects at intervals through the years 1883-87, at some of which the present writer assisted, Mr. Edmund Gurney had shown that it was possible by means of the unexpressed will of the agent to produce local anæsthesia in certain persons. (_S.P.R._, vol. i. pp. 257-260; ii. 201-205; iii. 453-459; v. 14-17.) In these experiments the subject was placed at a table, and his hands were passed through holes in a large brown paper screen, so that they were completely concealed from his view. Mr. G. A. Smith then held his hand at a distance of two or three inches from the finger indicated by Mr. Gurney, at the same time willing that it should become rigid and insensible. On subsequently applying appropriate tests it was found, as a rule, that the finger selected had actually become rigid and was insensible to pain. In the last series of 160 experiments Mr. Gurney, as well as Mr. Smith, held his hand over a particular finger. In 124 cases the finger over which Mr. Smith's hand had been held was alone affected; in 16 cases Mr. Gurney and Mr. Smith were both successful; in 13 cases Mr. Gurney was successful and Mr. Smith failed. In the remaining 7 cases no effect at all was produced. It is noteworthy that in a series of 41 similar trials, in which Mr. Smith, while holding his hand in the same position, willed that no effect should be produced, there was actually no effect in 36 cases; in 4 cases the finger over which his hand was held, and in the remaining case another finger, were affected. The rigidity was tested by asking the subject, at the end of the experiment, to close his hands. When he complied with the request the finger operated on--if the experiment had succeeded--would remain rigid. The insensibility was proved by
