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, intended for use in hypnotic therapy as an attention focus, and, specifically, "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.
