Still, the fluidic hands emit a light of their own; and the question is, Can this emitted light penetrate solid substances—"matter," as we understand it? As the result of a number of experiments, Dr. Ochorowicz ascertained that, in the majority of cases, these rays, like ultra-violet light, did not penetrate solid substances, as do the X-rays; yet their actinic action was found to be far stronger! Here is a field for long-continued observation and experiment. In thought photography, on the other hand, it has been ascertained that the rays can pass easily through solid matter, like the X-rays.
The next question of interest which presented itself for solution was this: To what extent can the fluidic hands change their form, size, and contour at will? Experiments were first tried in the reduction of the size of the hands, upon request.
Three plates were prepared and laid in a series upon the table at some distance from the medium. Through the entranced somnambule the "double" was then informed of the experiment, and asked to place its hand upon the three plates in succession, willing on each occasion to make the fluidic hand smaller. This was done. An impression of the same hand was obtained on each plate, but it can be seen that, on each occasion, the hand is smaller in size. This was all accomplished within a few seconds.
Of these experiments Dr. Ochorowicz says:
"We are therefore justified in arriving at the following conclusions:
"1. At first, the double's hand is larger than that of the medium.
"2. It tends to decrease in length and general size.
"3. The palm of the hand, especially, tends to decrease.
"4. Only the little finger remains without appreciable change.
"5. The change is that of several millimetres, but not enormous.
"6. The fingers of the double tended to close nearer together, as well as become smaller—just as an ordinary hand would probably do."
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."
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.
Dr. Ochorowicz tried to draw the film from the bottle, but failed; he was finally obliged to break the bottle to extract it. The film was then developed, and upon it was the imprint of a hand—larger even than his own, to say nothing of the medium's—clearly formed. Fraud was absolutely out of the question. There seems only the alternative choice of invoking the fourth dimension, or assuming that the fluidic hand could curve itself round and round the film after having entered the bottle in some manner! The facts seem incredible; but I give them as recorded.
The question now arises: is the fluidic hand two-dimensioned? It could hardly have any thickness, to accomplish the last experiment. Dr. Ochorowicz determined to try a novel experiment, to test this theory.
Two photographic plates were placed face to face, separated by small pieces of cardboard at the corners. The "double" was requested to insert its hand between the plates when the medium was entranced. Upon the plates being developed, the imprint of a hand (the same hand) was found on both plates; i.e. a photograph of the top, and of the under side of a hand. This was repeated again, under more stringent conditions. The hand again appeared.
It was then decided to repeat the experiment with the rolled film in the bottle. The experiment was again made; the film was developed when the medium reclined on the couch on the opposite side of the room, and a very large hand was again found to have impressed itself upon the film. It had evidently succeeded in curling itself round the rolled film in the closed bottle!
The question is: First, Do the facts occur? And if they do, what is the cause of them? What is the nature of these fluidic hands? To whom do they belong? Of what are they constituted? Are they the hands of a spirit, or mere exteriorizations from the body of the medium—materializations, only partially independent?
Without attempting to answer these questions in this place, I will conclude by pointing out two facts, which seem to me of considerable importance. The first is that many nervous and mentally abnormal patients may be mediums were the pains taken to ascertain that fact. I know of one famous alienist who confided to me his belief that a very large percentage of mediumistic cases could be found in hospitals for hysterical patients or in wards for the mentally unbalanced. The trouble is that experiments tending to ascertain the truth of such a theory are never tried. Had not Dr. Ochorowicz been interested in things psychic, Mlle. Tomczyk would simply
