Sin,—Touching your suggested explanation of Mr. Rider Haggard's dream (see

Spectator, July 23rd), is there any evidence for precisely " that kind of unconscious travelling" ? Perception at a distance seems always to be conditioned by conscious anxiety or effort which impresses the subliminal self. I believe there is no evidence for subconscious travel- ling and observation apart from suggestion. In Mr. Rider Haggard's case there was no anxiety or strain save on the part of the dog. There is • a previous, authenticated instance

of telepathy between a dog and his mistress occurring about the time of the dog's death.—I am, Sir, &c.,
