A less successful but not perhaps on that account less satisfactory confirmation has been obtained by another amateur, who, after eighteen months of experiment, obtained a partial success. Mr. R. Williams, M. A., Ph. D., of Hayward’s Heath, succeeded last summer in obtaining three photographs, each with part of a human form besides the sitter, one having the features distinctly marked. Subsequently another was obtained, with a well-formed figure of a man standing at the side of the sitter, but while being developed, this figure faded away entirely. Mr. Williams assures me (in a letter) that in these experiments there was “no room for trick or for the production of these figures by any known means.” The editor of the British Journal of Photography has made experiments at Mr. Hudson’s studio, taking his own collodion and new plates, and doing everything himself, yet there were “abnormal appearances” on the pictures, although no distinct figures. We now come to the valuable and conclusive experiments of Mr. John Beattie, of Clifton, a retired photographer of twenty years’ experience, and of whom the above-mentioned editor says: “Every one who knows Mr. Beattie will give him credit for being a thoughtful, skillful, and intelligent photographer, one of the last men in the world to be easily deceived, at least in matters relating to photography, and one quite incapable of deceiving others.” Mr. Beattie has been assisted in his researches by Dr. Thomson, an Edinburgh M. D., who has practiced photography, as an amateur, for twenty-five years. They experimented at the studio of a friend, who was not a Spiritualist (but who became a medium during the experiments), and had the services of a tradesman—with whom they were well acquainted—as a medium. The whole of the photographic work was done by Messrs. Beattie and Thomson, the other two sitting at a small table. The pictures were taken in series of three, within a few seconds of each other, and several of these series were taken at each sitting. The figures produced are, for the most part, not human, but variously-formed and shaded white patches, which in successive pictures change their form, and develop, as it were, into a more perfect or complete type. Thus, one set of five begins with two white somewhat angular patches over the middle sitter, and ends with a rude but unmistakable white female figure, covering the larger part of the plate. The other three show intermediate states, indicating a continuous change of form from the first figure to the last. Another set (of four pictures) begins with a white vertical cylinder over the body of the medium, and a shorter one on his head. These change their form in the second and third, and in the last become laterally spread out into luminous masses resembling nebulæ. Another set of three is very curious. The first has an oblique flowing luminous patch from the table to the ground; in the second, this has changed to a
