February 3, 1925. “Harry Houdini, author, lecturer and master magician, today gave a lecture to members of the New York clergy and their congregations under the auspices of the New York Federation of Churches. The meeting was held at the New York Hippodrome. Houdini is devoting most of his time to exposing alleged spiritualists who are imposing on the public. He is shown here demonstrating a method that is used in communication.
William B. Millard, General Secretary of the Federation, is aiding in the demonstration. While Houdini’s ‘foot’ is held by Millard, he shows how it is possible to ring a bell.
