“There is a Psychic Ether, related to thought, as the luminiferous ether is to light. . . . All the so-called occult phenomena of mesmerism, trance, clairvoyance, mind reading, dreams, visions, thought transference, etc., are correlated to and explained by means of this psychic ether.” A fairly extensive work from one half the Ohio Spiritualist husband and wife team of Hudson Tuttle and Emma Rood Tuttle.
