A few weeks later, in January 1883, at the invitation of the Committee of the Society for Psychical Research, Mr. Blackburn and Mr. Smith came from Brighton, and a series of experiments was conducted at the Rooms the Society then occupied in Dean's Yard, Westminster. For the Report embodying the results of these experiments, Mr. Myers, Mr. Gurney, and Professor Barrett are specially responsible. Two drawings, Nos. 10 and 11, are selected from a series of twenty-two made on this occasion. As to No. 10, Mr. S. had no idea that the original was not a geometrical diagram. Nor had he any clue given him as to the character of No. 11. He added the line marked _b_ some time after he had drawn the line marked _a_, saying that he saw "a line parallel to another somewhere." The authors of this Report say: "It is almost needless to point out that in these observations so foreign to our common experience, it is indispensable to be minutely careful and conscientious in recording the exact conditions of each experiment." The reader is referred to the Report itself to show how this was carried out; and also to show how exhaustively every possibility was considered by means of which information could be conceived to be conveyed through any recognised channel.
