THE SOMNAMBULISTIC STAGE
Dr. Charcot thus describes a curious experiment: "A portrait is suggested to a subject as existing on a blank card, which is then mixed with a dozen others; to all appearance they are similar cards. The subject, being awakened from his hypnotism, is requested to look over the packet, and does so without knowing the reason of the request, but when he perceives the card on which the portrait was suggested, he at once recognizes the imaginary portrait. It is probable that some insignificant mark has,owing to his visual hyperacuity, fixed the image in the subject's brain."
