These rays may be centred and concentrated by the action of the will of the subject. They radiate from the surface of the skin and reproduce a simulacrum, as it were, of the surface. They throw a shadow of any object placed between the subject and the photographic plate. They are more penetrating than the rays discovered by M. Darget, and brought to the attention of the French Academy several years ago. Interesting analogies may exist here between these rays and the so-called "Black Light" of M. Le Bon, which he describes at length in his work, The Evolution of Forces.
It was now determined to attempt more interesting and startling experiments. The medium was requested to hold her right hand in the air, where it could be seen plainly, against the faint red light in the room. It was not moved throughout the experiment. In his own laboratory Dr. Ochorowicz then procured a fresh plate and held it in the air, at some distance from the hand of the medium. The latter then said: "Ah, I see another right hand detaching itself from my arm and approaching the plate. How it pains me! Yes, it is placing itself over the plate—it is done."
Dr. Ochorowicz then took the plate with him at once to the dark room and, when it was developed, there was found the outline of an unformed hand—one apparently in the process of condensation. It was, as it were, a hand in embryo. It had apparently become detached, or had detached itself, from the medium, and remained sufficiently solid to leave an impression of itself upon the plate, held about half a metre from it. It was, in fact, a form of materialization, but of so shadowy a texture that it remained often quite invisible to the onlooker.
A long series of experiments is then described, which might be condensed somewhat as follows:—
"The somnambule said that she did not see the double's hand leave hers, but saw it placed upon the plate. It was placed upon it at an angle of ninety degrees from the position taken by her own hand. At my request the thumb was made particularly distinct, the whole hand being quite different in contour from that of the medium.
"I take another plate, and hold it some distance from the medium's hand. She makes an effort to impress it, with the result that an immense finger, superhuman in size, is seen upon the plate when developed. Upon the next plate, which I hold about twenty-five centimetres from her hands, three fingers appear, non-luminous—the light seeming to come from behind the hand, and shining through the spaces between the fingers.
"I now hold a plate at a distance of one metre from her right hand, which is held up in front of her. The red light is turned slightly low. The somnambule sees a shadowy hand detach itself from hers, which is at the same time, also, attached to a very long, thin arm, and which approaches the plate. The hand is very large, she says, and is a right hand. It places itself over the plate, which I thereupon remove and develop. A large hand is distinctly visible upon it. Finally, I hold a plate two and a half metres away from the medium's hand. The somnambule shivers and feels cold in her lower limbs, despite the fact that my laboratory is very warm. She again holds out her right hand, and a left hand, attached to a long, thin arm, is seen by her to detach itself and place itself over the plate held in my hand. Upon being developed, the impression of a very large left hand was found upon the plate—so large that only a portion of the hand could be seen! The whole of the medium's hand can easily be placed upon the plate. These are very similar to the enormous hands frequently seen in the Palladino séances, and said to be those of 'John King.'
"From the above facts I think we are justified in arriving at the following tentative conclusions:
"1. That the hand of the double can be larger than that of the medium.
"2. That a left hand can be projected from a right arm, drawing its force from the entire body of the subject, this being accompanied by a chilly feeling in the extremities and by congestion of the head.
