"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."
To resume the experiments: Dr. Ochorowicz desired to see whether the fluidic hand of the double could pass through a very small hole or space. He accordingly proposed placing a rolled-up film in a bottle, leaving only the small hole at the top, and see whether the hand could impress itself under these circumstances. Upon this being proposed to the medium, she exclaimed: "Make it more difficult than that; you will make the double lazy! Cork up the bottle!"
Dr. Ochorowicz accordingly cut a film, rolled it into a small roll, placed it in the bottle, and held the latter between his two hands, the right-hand palm acting as a cork, the left supporting the bottle; the medium placed her hands on either side of the bottle, on the outside. She soon complained that her hands were paining her, seeming to swell and get larger. She was soon after seized with cramps, and the experiment was at this point discontinued.
