_Levitations._--One day we improvised an experiment in the afternoon, and I remember that I observed a very interesting levitation made under these circumstances. It was about five o'clock in the evening (at any rate it was broad daylight), in the salon at l'Agnelas. We took our places about the table, _standing_. Eusapia took the hand of one of us and placed it on the corner of the table, at her right. The table thereupon rose up to the height of our foreheads; that is to say, the top of the table rose at least as high as five feet above the floor. Such experiments were very convincing, for it was impossible for Eusapia, the circumstances being such as they were, to lift the table by a normal act. It is enough to suppose that she merely touched the corner of the table, to find out how heavy a weight she would have had to lift if she had made a muscular movement. Besides, she had not a sufficient grip on the table to lift it. Evidently, the conditions of the experiment being such, she could not make use of one of the fraudulent processes mentioned by her critics, such as straps or hooks of any kind. The phenomenon is undeniably authentic. The breathing seems to have a very great influence. In the way things take place, it seems as if the sitters released, by breathing, an amount of motor energy comparable to that which they release when rapidly moving their limbs. There is something in this very curious and difficult to explain. The more complete analysis of the facts allows us to think that the liberation of the energy employed depends upon the contraction of the muscles and not upon the movement made. The thing which reveals this peculiarity is easy to observe. When we are forming the chain about the table, we can set up a movement without contact by mutually pressing our hands together with a certain force, or by pressing the feet hard upon the floor. The first of these means is much the better of the two. The arms have only made an insignificant movement, and one can say that the muscular contraction is almost the only physiological phenomenon observable. Yet it suffices. All these authenticated experiments tend to show that the agent which determines movements without contact has some connection with our organism, and probably with our nervous system.
