SPIRITUALISM, MEDIUMSHIP AND SEANCES - EGLINGTON Chromolithograph depicting a spirit hand - part of a materialization in a seance, held circa 1884. Some students of Eglington insist that this hand is of Eglington's spirit control, Joey. The purpose of the lighted object held in the hand is not clear. The seance in question was one conducted by the famous medium, William Eglington. Lithograph from John S. Farmer, Twixt Two Worlds. A Narrative of the Life and Work of William Eglington, 1886.
