The light which supplied the necessary illumination for these photographs seemed to have been emitted from a sort of "egg," near the wrist of the hand, which was intensely luminous. This was not expected, and came as a surprise. Two suggestions as to its nature at once present themselves: (1) that it is a self-created mediumistic light; and (2) that it is a mass of matter from which the hand derives its material sustenance. In a further series of experiments, during which Dr. Ochorowicz was repeatedly touched by a cold hand, impressions of large left hands were left upon the plates--the medium's left hand being, meanwhile, a long way removed from the plate. The fingers were very large, the thumb enormous and abnormally shaped at the end. Summing up the conclusions which, he thought, could be drawn from his researches, Dr. Ochorowicz said: "1. Fluidic hands are detached more or less rarely--according to the condition of the subject's "forces." When these are strong, hands may even be produced unknown to the medium. "2. The direction and character of these hands are determined by the subconscious mind of the medium; but also partially by the conscious mind. "3. The properties of the fluidic hands are not constant; they change frequently. "4. These changes represent transformations of energy--certain forms of energy being transformed into other forms. When the conditions are good, the forms of available energy are multiplied; when weak, they are lessened. They alternate, but do not blend. The mechanical effects are produced chiefly by the invisible hands, while the visible hands are inactive. "5. I have never seen more than two hands formed by one medium at one time, and more usually only one. When there are two hands, however, they may be quite dissimilar, one from the other. "6. There are several degrees of materiality, which succeed each other rapidly. The hands are so fugitive that it is almost impossible to seize them. When the imperfectly formed hands are grasped, however, they are cold, slippery, and unpleasant to the touch. The better materialized hands, on the contrary, are warm and life-like. "7. The well-materialized hands can be photographed; even the poorly-developed hands can give radiographs. "8. The ultra-violet light necessary to produce these photographs can be produced by the hand of the medium or by the double itself. "9. Radiographs are difficult to obtain; a materialization generally loses its luminosity. "10. The hands are sometimes like, and sometimes unlike, those of the medium. "11. The fluidic hands can be moulded plastically, and altered as to their dimensions."
