d 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
