The recent lecture on “Spirit Photography,” given by Mr. J. Traill Taylor before a large audience, composed of the members of the London and Provincial Photographic Association and their friends, is being much talked about in photographic circles. Mr. Taylor, whose personal _bonâ fides_ in the matter are admitted to be quite above suspicion, showed upon an ordinary lantern screen the results which he had obtained. The conditions under which the spirit experiments were conducted were as follows:—Mr. Taylor used his own binocular stereoscopic camera, and provided himself with unopened packages of “Ilford” dry plates, purchased from dealers of repute. He exposed the plates by means of magnesium ribbon in the presence of a medium. At the first attempt, between the camera and the sitter a female figure was developed. On several of the other plates exposed various figures were also discovered. It was distinctly asserted by Mr. Taylor that none of these were visible to him at any time during the exposure in the camera, and he vouched that no one had the slightest opportunity of tampering with the plates before they were placed in the dark slide or immediately preceding development. _From THE MEDIUM AND DAYBREAK, March 24th, 1893._[10] THE EXPERIMENTS IN SPIRIT PHOTOGRAPHY.—We call attention to certain important points in Mr. Taylor’s paper and the remarks which follow it. The first consideration is, that nothing should be jumped at as fraud, though it may appear to be so. Mr. Taylor has taken a strong, manly position in exhibiting photographs which have all the appearance of being spurious, and yet he knows they are not so. A man in a position less eminent could not afford to be so bold. Mr. Glendinning dwells on this feature of the investigation in an excellent manner. The photograph obtained without exposure at all, described at the close of the report, suggests a means of producing pictures quite unknown to science or photographic art. It, in its way, resembles the direct writing on closed slates, or on unopened packets of paper. But on carefully examining Mr. Taylor’s negatives it appears as if the spirit figures had not been cut out and stuck on, but there is a blending of the one picture with the other, showing plainly that a different mode of operation was at work. We have often observed in our lectures that the nature of the image differs in the pictures of every spirit photographer. Evidently the photographers on the other side have taken up Mr. Taylor’s challenge to investigate in a very serious manner, and have shown some of their skill to set the brains of mortal photographers on the alert for a more comprehensive knowledge of the possibilities involved in their art.
