Every one interested in psychic phenomena who makes a pilgrimage to the Capital of the Nation visits the house of Dr. Theodore Hansmann. For ten years Dr. Hansmann has been an ardent student of Spiritualism, and has had sittings with many celebrated mediums. The walls of his office are literally covered with spirit pictures of famous people of history, executed by spirits under supposed test conditions. There are drawings in color by Raphael, Michel Angelo, and others. In one corner of the room is a book-case filled with slates, upon the surfaces of which are messages from the famous dead, attested by their signatures. In the fall of 1895, a correspondent of the _New York Herald_ interviewed Doctor Hansmann on the subject of spirit photographs, and subsequently visited the United States Bureau of Ethnology, where an interview was had with Mr. Dinwiddie, an expert photographer. Here is the substance of this second interview, published in the _Herald_, Nov. 9, 1895. "Dr. Hansmann's collection of 'spirit' photographs is most interesting. There is one with the face of the Empress Josephine, and on the same plate is the head of Professor Darius Lyman, for a long time Chief of the Bureau of Navigation. The head of the Empress Josephine has a diadem around it, and the lights and shadows remind one of the well known portrait of her. On another plate are Grant and Lincoln, Among his other photographs Dr. Hansmann brought out one of a man who was described to me as an Indian agent. Around his head were eleven smaller 'spirit' heads of Indians. In looking at the blue print closely it seemed to me as if I had seen those identical heads--the same as to light, shade and posing--somewhere before. "I was aided at the Bureau of Ethnology of the Smithsonian Institution by Mr. F. Webb Hodge, the acting director, who on looking at the blue print named the Indians directly; several of the pictures were of Indians still alive. This, of course, immediately disposed of the idea of the blue print Indians being spirits. [Illustration: FIG. 29--SPIRIT PHOTOGRAPH. [Taken by the Author.]] "Moreover, Mr. Dinwiddie produced the negatives containing the identical portraits of these Indians and made me several proofs, which on a comparison, feature by feature, light for light, and shade for shade, show unquestionably that the faces on the blue print are copies of the portraits made by the photographer of the Bureau of Ethnology. "Mr. Dinwiddie asked me to sit down for awhile, and offered to make me some spirit photographs. This he did, and the results obtained may be considered as far better examples of the art of 'spirit' photography than those of the medium, Keeler.
