Insanity and Spiritualism

To the Editor of the "Daily Express."
Sir, — May I ask Mr. Griggs to quote any exact evidence or statistics on which he founds his assertion that there is a connection between spiritualism and insanity? Dr. Forbes Winslow made the same statement, but after fuller inquiry he had the manliness to make a complete refraction. I trust that Mr. Griggs will either do the same or will give some figures in support of his serious assertion.
I may say that my experience, which covers more than thirty years, is directly opposed to Mr. Griggs, and that I can only recall one case where a temporary derangement was associated with automatic writing. Since Mr. Griggs quotes his medical qualifications, I beg leave to sign myself.
ARTHUR CONAN DOYLE.
