In January, 1869, the London Dialectical Society appointed a committee with thirty-three members to investigate the phenomena alleged to be Spiritual manifestations and to report on its findings. Professor Huxley, Professor John Tyndall, and Mr. George Henry Lewes, were invited to co-operate with the Committee. Professor Huxley refused to have anything to do with the investigation and in the following letter, written in answer to the Committee’s invitation, he terms Spiritualism a “gross imposture.”[106] “Sir,--I regret that I am unable to accept the invitation of the Council of the Dialectical Society to co-operate with a Committee for the investigation of ‘Spiritualism’, and for two reasons. In the first place, I have no time for such an inquiry, which would involve much trouble and (unless it were unlike all inquiries of that kind I have known) much annoyance. In the second place, I take no interest in the subject. The only case of ‘Spiritualism’ I have had the opportunity of examining into for myself was as gross an imposture as ever came under my notice. But supposing the phenomena to be genuine--they do not interest me. If anybody would endow me with the faculty of listening to the chatter of old women and curates in the nearest cathedral town, I would decline the privilege, having better things to do. “And if the folk in the Spiritual world do not talk more wisely and sensibly than their friends report them to do, I put them in the same category. “The only good that I can see in a demonstration of the truth of ‘Spiritualism’ is to furnish an additional argument against suicide. Better live a crossing-sweeper than die and be made to talk twaddle by a ‘medium’ hired at a guinea a _seance_. “I am, Sir, &c., “T. H. Huxley.” “29th January, 1869.” A few days later Mr. Lewes declined the Committee’s invitation as follows: “Dear Sir,--I shall not be able to attend the investigation of ‘Spiritualism’; and in reference to your question about suggestions would only say that the one hint needful is that all present should distinguish between facts and inferences from facts. When any man says that phenomena are produced by _no_ known physical laws, he declares that he knows the laws by which they are produced. “Yours, &c., “G. H. Lewes. “Tuesday, 2nd February, 1869.” Under date of December 22, 1869, Professor Tyndall wrote the following in response to his invitation to aid the Committee. “Sir--You mention in your note to me three gentlemen, two of whom are personally known to me, and for both of whom I entertain a sincere esteem.
