distance, and preventing the left hand sitter using the hand to feel about and discover the right hand sitter's hand on the wrist of the hand holding his. You will see, now, that although both sitters are holding the same hand each one thinks he is holding the one on his or her side of the medium. The balance of the séance is easy." An amusing incident happened during my sitting with Mr. Tabor. Growing somewhat weary waiting for him to "manifest," I determined to undertake some materializations on my own account. I adopted the subterfuge of getting my right hand loose from the lady on my right, and produced the spirit hand that clasped the wrist of several of the sitters in the circle. Mr. X-- asked "Jim" if everything was all right in the circle, every hand promptly joined, and the magnetic conditions perfect. "Jim" responded with three affirmative taps on the table top. I congratulate myself on having deceived "Jim," a spirit operating in the fourth dimension of space, and supposedly cognizant of all that was transpiring at the séance. Once, when the medium was floating the trumpet over my head, I grasped the instrument and dashed it on the table. He made no further attempt to manipulate the trumpet in my direction, and very shortly brought the séance to a close. No written communications were received during the evening. 4. Spirit Photography. You may deceive the human eye, say the advocates of spirit materializations, but you cannot deceive the eye of science, the _photographic camera_. Then they triumphantly produce the spirit photograph as indubitable evidence of the reality of ghostly materializations. "Spirit photography," says the late Alexandre Herrmann, in an article on magic, published in the _Cosmopolitan Magazine_, "was the invention of a man in London, and for ten years Spiritualists accepted the pictures as genuine representations of originals in the spirit land. The snap kodak has superseded the necessity of the explanation of spirit photography." To be more explicit, there are two ways of producing spirit photographs, by _double printing_ and by _double exposure_. In the first, the scene is printed from one negative, and the spirit printed in from another. In the second method, the group with the friendly spook in proper position is arranged, and the lens of the camera uncovered, half of the required exposure being given; then the lens is capped, and the person doing duty as the sheeted ghost gets out of sight, and the exposure is completed. The result is very effective when the picture is printed, the real persons being represented sharp and well defined, while the ghost is but a hazy outline, transparent, through which the background shows.
