“_The two plates were taken from the same packet, loaded into the dark slide at the same time, with the same dark room light and the same distance from the light. They were then exposed on the same subject immediately after each other; the same length of exposure being given (I counted them mentally) with the same aperture of lens. The plates were then placed side by side in the same dish of developer and I contend that the image must come up at a uniform speed on both plates and that it is impossible for one to flash up before the other and darken all over unless it was previously exposed, especially when there was no variation in the light when the exposure was made, it being three P.M., December 16, clear sky, no sunshine._ “An ‘extra’ did appear on this (one fourth plate). It is a clean shaven face above mine and drapery hanging from it. On my own three and a half by two and a half a light splotch is over my face. Mrs. Buxton informed me that it was a ‘Spirit light’ but Mr. Hope believed he saw the faint features of a face in it.” While in Denver, Colorado, in May, 1923, I called one morning on Mr. Alexander Martin, whom Sir Arthur Conan Doyle had told me was a noted psychic photographer and a very wonderful man in his particular line. Doyle himself had called on Martin the day before but as Martin did not feel in the mood there had been no demonstration. In this Sir Arthur was no more unfortunate than Hyslop, the eminent Psychic investigator, who, according to Sir Arthur, had made a special journey from England to Denver in order to have a seance with Martin but had not been successful. Martin lived about fifteen minutes out of town by taxi. I took with me my chief assistant, James Collins, so I would have a witness if anything of a psychic nature occurred. Collins had my camera as I wanted at least to get a picture of Martin. We found him standing in the doorway of a rear building and after I introduced myself he seemed cordial. I showed him some Spirit photographs which I had with me and after a few minutes talk I asked him if he was willing that Collins should take a snap-shot at us. He thought I was asking for a sitting and replied that he did not feel good and besides had been engaged to take the pictures of the children in two schools. I kept on talking in my most entertaining manner and before long he invited us into the house saying he would photograph both of us. Meanwhile Collins had secured five snap-shots at close range without Martin knowing it. When we went into the house I walked right into the dark room but Martin called me saying: “Now don’t you go in there, just wait a minute.”
