"In a conversation with Mr. B— as to how these shadow pictures, as he called them, came on the plate, I found him almost as much at sea as myself. He said that he did not know how they came, but that he had noticed that they came more frequently and with greater distinctness at some times than at others. He could never say beforehand whether they would come or not. He frequently informed me when my sitting began that he could guarantee nothing. And often the set of plates would bear no trace of any portrait save mine.

"He was very reluctant to continue the experiments, and used to complain that after exposing four plates with a view to obtaining such pictures he felt quite exhausted. And sometimes he complained that his 'innards seemed to be turned upside-down,' to use his own phrase. I usually sat with him between two and three in the afternoon, and on the days which I came he always abstained from the usual glass of beer which he took with his midday meal. If I came unexpectedly, and he had had a single glass of beer, which formed his usual beverage, he would always assure me that I need not expect any good results. I, however, never found any particular difference in the results.

"We often discussed the matter together. And he was evidently working out a theory of his own, as any one might under such circumstances. He knew that when he was excited or irritated he got bad results. Hence he often used to keep a music-box going, for the music, in his opinion, tended to set up good and tranquil conditions. He said he thought something must come out of him—what, he did not know, but something was taken out of him, and with this something he thought the entities, whoever they were, built themselves up and acquired sufficient substance to reflect the rays of light so as to impress the sensitive plate in his camera. He also thought that his old camera had become what he called magnetized, and although it was an old-fashioned piece of furniture, which I not only examined myself, but have had examined by expert photographers, nothing could be discovered within or without it which would account for the results obtained. He also was of the opinion that even although he did not touch the photographic plate, it was necessary for him to touch or to hold his hand over the photographic slide, and also to hold his hand over the plate when it was in the developing bath. His theory was that in some way or other this process magnetized the plate and brought out a shadow portrait.

"One peculiarity of almost all the shadow pictures obtained in all these series of experiments is that they have around them the same kind of white drapery which is so familiar to those who have taken part in a materializing séance. Sometimes this drapery is more voluminous than at others; often, when the conditions are good, the form which at first appears with its head encompassed with drapery will appear on the second plate without any drapery. On asking Mr. B— what explanation he could give for this, he said he did not know, but he believed that the bodily appearance assumed by the spirit was very sensitive and needed to be shielded from currents, which might harm it. But when harmony prevailed they could venture to remove the drapery, and be photographed without it. Whatever may be the value of Mr. B—'s theory, there is little doubt that something is given off from his body which can be photographed. The white mist that appears to emanate from him forms into cloudy folds out of which there protrudes a more or less clearly defined face with human features. Sometimes this white and misty cloud obscures the sitter, at other times it seems to be condensed as if it were in the process of being worked up into a definite form for the completion of which either time or some other conditions were lacking. It was also noticeable that the entity—whoever it may be—which builds up the form, who is giving off sufficient solidity to impress its image upon the plate in the camera, having once created a form, will use it repeatedly without any change of position or expression. This will no doubt seem a great stumbling-block to many. But the fact is as I have stated it, and our first business is to ascertain facts, whether they tell for or against any particular hypothesis. It may be that the disembodied spirit, in order to establish its identity, constructs, out of the 'aura' given off by the photographer or other medium, a mask or cast bearing the unmistakable resemblance to the body which it wore in its sojourn on earth. Having once built it up for use in the studio, it may be easier to employ the same cast again and again instead of building up a new one at each fresh sitting. Upon this point, however, I shall have something to say further on.

"I was very much interested in the results I obtained, although as none of the photographs were identified I did not deem the experiment completely successful. I was very anxious to induce Mr. B— to devote some months to an uninterrupted series of experiments, and asked him on what terms I could secure his services. But he absolutely refused; he said he did not like it, it made him unwell, made people speak ill of him, and it did not matter what terms were offered, he would not consent. He was an old man, he said, and he could not find out how these things came; and, in short, neither scientific curiosity nor financial consideration would induce him to consent to more than an occasional sitting. I therefore dropped the matter, and for some years I discontinued my experiments.

"I had a friend who often accompanied me to Mr. B—'s studio, where she had been photographed both with and without shadow pictures appearing on the background. We often promised each other that if either of us passed over we would come back and be photographed by Mr. B— if possible, in order to prove the reality of spirit return. Shortly after this my friend died. But it was not until nearly four years after her death, at the request of a friend who was very anxious to know whether she could communicate with those on the other side, that I went back to Mr. B—'s studio.

"He had always been slightly clairvoyant and clairaudient. He told me that a few days before I had written asking for the appointment, my deceased friend had appeared in the studio and told him that I was coming. This reminded me of her promise, and I said at once that I hoped he would be able to photograph her. He said he didn't know; he was rather frightened of her, for reasons into which I need not enter, but if she came he would see what he could do. My friend and I sat together. The first plate was exposed, nothing appeared in the background. When the second plate was placed in the camera Mr. B— nodded with a quick look of recognition. We saw nothing. After he had exposed the second plate and before he developed it he asked us to change seats. We did this, and as he was exposing the third plate he said, 'I am told to ask you to do this,' and then when he closed the shutter he said, 'it is Mrs. M—.' On the fourth plate there appeared a picture of a woman whom I had never seen before, and whom my friend had never seen, neither had Mr. B—. When the plates came to be developed I found the second and third plates contained unmistakable likenesses of my friend Mrs. M—. These portraits were immediately recognized by my friend as unmistakable likenesses of the deceased Mrs. M—. It will be objected that she had frequently been photographed by the same photographer, and that he had simply faked a photograph from one of his old negatives. I don't believe that this is possible, for these portraits, although recognized immediately by every one who knew her, including her nearest relative, are quite different from any photograph she ever had taken in life. She certainly never was photographed enveloped in white drapery, nor do I believe that Mr. B— had any negative of any of her portraits in his possession. But I fully admit that from the point of view of one who wishes to exclude every possibility of error, the fact that Mrs. M— had been frequently photographed in her lifetime by the same photographer renders it impossible to regard these photographs as conclusive testimony as to their authenticity as a photograph of a form assumed by a disembodied spirit. I have mentioned that on the fourth plate there appeared a portrait of an unknown female. On my return I was showing the print of this shadow picture to a friend when she startled me by declaring that the shrouded form which appeared behind me in the photograph was a portrait of her mother who had died some months before in Dublin. I had never seen her mother, my friend did not know of her existence, neither did the photographer, nor does he to this day. It was only many months afterwards that I was able to obtain a photograph of my friend's mother, but it was taken when she was a comparatively young woman and bore no manner of resemblance to the portrait of the lady who appeared behind me. Her daughter, however, had not the slightest hesitation in asserting that it was her mother, that she had recognized her instantly, and that it was a very good portrait of her as she appeared in the later years of her life. This startled me not a little, and convinced me that I had a good prospect of attaining some definite results as an outcome of my experiments.

"Mr. B—, encouraged by this success, was willing to continue his experiments, and this time I insisted upon paying him for his work.

"From this time onward the occurrence of photographs that were recognizable on the background of the photographs taken by Mr. B— became frequent. Sometimes the plates were marked; but not invariably. For my part I attach comparatively no importance to the marking of plates and the close supervision of the operator. The test of the genuineness of a photograph that is obtained when the unknown relative of an unknown sitter appears in the background of the photograph, is immeasurably superior to precautions any expert conjurer or trick photographer might evade. Again and again I sent friends to Mr. B—, giving him no information as to who they were, nor telling him anything as to the identity of the persons' deceased friend or relative whose portrait they wished to secure; and time and again when the negative was developed the portrait would appear in the background, or sometimes in front of the sitter. This occurred so frequently that I am quite convinced of the impossibility of any fraud. One time it was a French editor, who finding the portrait of his deceased wife appear on the negative when developed, was so transported with delight that he insisted on kissing the photographer, Mr. B—, much to the old man's embarrassment. On another occasion it was a Lancashire engineer, himself a photographer, who took marked plates and all possible precautions. He obtained portraits of two of his relatives and another of an eminent personage with whom he had been in close relations. Or again, it was a near neighbor, who, going as a total stranger to the studio, obtained the portrait of her deceased daughter.

"I attach no importance whatever to the appearance of portraits of well-known personages, which might easily be copied from existing pictures, but I attach immense importance to the production of the spirit photographs of unknown relatives of sitters who are unknown to the photographer, who receives them solely as a lady or gentleman who is one of my friends.
