"'Spirit photography, so called, has of late been asserting its existence in such a manner and to such an extent as to warrant competent men in making an investigation, conducted under stringent test conditions, into the circumstances under which such photographs are produced, and exposing the fraud should it prove to be such, instead of pooh-poohing it as insensate because we do not understand how it can be otherwise—a position that scarcely commends itself as intelligent or philosophical. If, in what follows, I call it "spirit photography," instead of psychic photography, it is only in deference to a nomenclature that extensively prevails.... I approach the subject merely as a photographer.'
"Mr. Taylor then gives a history of the earlier manifestations of spirit photography, and goes on to explain how striking phenomena in photographing what is invisible to the eye may be produced by the agency of florescence. He quotes the demonstration of Dr. Gladstone, F.R.S., at the Bradford meeting of the British Association in 1873, showing that invisible drawings on white cards have produced bold and clear photographs when no eye could see the drawings themselves. Hence, as Mr. Taylor says: 'The photographing of an invisible image is not scientifically impossible.'
"Mr. Taylor then proceeds to describe some personal experiments. He says: 'For several years I have experienced a strong desire to ascertain by personal investigation the amount of truth in the ever-recurring allegation that figures, other than those visually present in the room, appeared on the sensitive plate.... Mr. D., of Glasgow, in whose presence psychic photographs have long been alleged to be obtained, was lately in London on a visit, and a mutual friend got him to consent to extend his stay in order that I might try to get a psychic photograph under test conditions. To this he willingly agreed. My conditions were exceedingly simple, were courteously expressed to the host, and entirely acquiesced in. They were that I, for the nonce, would assume them all to be tricksters, and, to guard against fraud, should use my own camera and unopened packages of dry plates purchased from dealers of repute, and that I should be excused from allowing a plate to go out of my own hand till after development, unless I felt otherwise disposed; but that as I was to treat them as under suspicion, so must they treat me, and that every act I performed must be in the presence of two witnesses; nay, that I would set a watch upon my own camera in the guise of a duplicate one of the same focus—in other words, I would use a binocular stereoscopic camera and dictate all the conditions of operation....
"'Dr. G. was the first sitter, and, for a reason known to myself, I used a monocular camera. I myself took the plate out of a packet just previously ripped up, under the surveillance of my two detectives. I placed the slide in my pocket and exposed it by magnesium ribbon which I held in my own hand, keeping one eye, as it were, on the sitter, and the other on the camera. There was no background. I myself took the plate from the dark slide, and, under the eyes of the two detectives, placed it in the developing dish. Between the camera and the sitter a female figure was developed, rather in a more pronounced form than that of the sitter.... I submit this picture.... I do not recognize her, or any of the other figures I obtained, as like any one I know....
"'Many experiments of like nature followed; on some plates were abnormal appearances, on others none. All this time Mr. D., the medium, during the exposure of the plates, was quite inactive....
"'The psychic figures behaved badly. Some were in focus, others not so. Some were lighted from the right, while the sitter was from the left; some were comely ... others not so. Some monopolized the major portion of the plate, quite obliterating the material sitters.... But here is the point: Not one of these figures which came out so strongly in the negative was visible in any form or shape to me during the time of exposure in the camera, and I vouch in the strongest manner for the fact that no one whatever had an opportunity of tampering with any plate anterior to its being placed in the dark slide or immediately preceding development. Pictorially they are vile, but how came they there?
"'Now, all this time I imagine you are wondering how the stereoscopic camera was behaving itself as such. It is due to the psychic entities to say that whatever was produced on one-half of the stereoscopic plates was produced on the other—alike good or bad in definition. But, on a careful examination of one which was rather better than the other ... I deduce this fact, that the impressing of the spirit form was not simultaneous with that of the sitter.... This I consider an important discovery. I carefully examined one in the stereoscope and found that, while the two sitters were stereoscopic per se, the psychic figure was absolutely flat! I also found that the psychic figure was at least a millimetre higher up in one than in the other. Now, as both had been simultaneously exposed, it follows to demonstration that, although both were correctly placed, vertically in relation to that particular sitter, behind whom the figure appeared, and not so horizontally, this figure had not only not been impressed on the plate simultaneously with the two gentlemen forming the group, but had not been formed by the lens at all, and that, therefore, the psychic image might be produced without a camera. I think this is a fair deduction. But still the question obtrudes: How came these figures there? I again assert that the plates were not tampered with by either myself or any one present. Are they crystallizations of thought? Have lens and light really nothing to do with their formation? The whole subject was mysterious enough on the hypothesis of an invisible spirit—whether a thought projection or an actual spirit, being really there in the vicinity of the sitter—but it is now a thousand times more so....
"'In the foregoing I have confined myself as closely as possible to narrating how I conducted a photographic experiment open to every one to make, avoiding stating any hypothesis or belief of my own on the subject.'"
Let us now return to some later experiments in psychic photography. Two small photographs, one showing a face, the other a series of small starlike markings, were sent to me by a member of the Society for the Study of Psychic Photography, of England. Writing of these prints, my correspondent says:
"A week or so ago we distributed one hundred and ten strips of sensitive film, in light-tight packages, for friends of the members to 'wear.' This was done with the idea of ascertaining approximately what percentage of individuals possessed this gift. We agreed that the films should be carried about for a week, and where possible worn round the forehead at night. The experiment proved more successful than we had anticipated, since six out of the one hundred and ten films were more or less affected. The two best results are those shown on the prints enclosed herewith." (Not shown.)
