Knowles Radio Hypnotic Crystal



The Knowles Radio Hypnotic Crystal is a glass bulb containing a quantity of sand, attached to a handle or fixed inside an aluminum holder, which is intended for use in hypnotic therapy as an attention focus, and, specifically, for "the production of Fascination, Healing, self treatment by auto-suggestion, the cure of bad habits, treatment at a distance, anesthesia, physiognomy, phrenology, graphology, and cheiromancy." It was originally marketed by Elmer Ellsworth Knowles (a.k.a. Elmer S. Prather) and his National Institute of Sciences as a training tool to be used in accompaniment with his courses in hypnotism, magnetic healing, and like studies.
