Levitation of One Side of the Table
We agreed to have the medium sit alone at the table, in full light, her two hands placed on its upper surface and her sleeves drawn back to the elbows.
We remained standing about her, and the space above and under the table was well lighted. Under these conditions the table rose at an angle of twenty to forty degrees, and so remained for some minutes, while the medium was holding her legs stretched out and striking her feet one against the other. When we pressed with the hand upon the lifted side of the table, we experienced a considerable elastic resistance.
The table was suspended by one of its ends to a dynamometer which was coupled to a cord: this cord was tied to a small beam supported upon two wardrobes.
Under these conditions, the end of the table having been lifted six and a half inches, the dynamometer showed seventy-seven pounds. The medium sat at the same narrow end of the table, with her hands wholly on the table, to the right and the left of the point where the dynamometer was attached. Our hands formed the chain upon the table, without pressure: they would not have been able in any case to do more than increase the pressure brought to bear on the table. On the contrary, the desire was expressed that the pressure should diminish, and soon the table began to rise on the side of the dynamometer. M. Gerosa, who was following the marks on the apparatus, announced this diminution, expressed by the successive figures 7½, 4½, 2½, 0 (pounds). At the last the levitation was such that the dynamometer rested horizontally on the table.
Then we changed the conditions by putting our hands under the table. The medium, especially, put hers, not under the edge, where it might have touched the vertical border-board and exercised a push downwards, but under the rail that unites the feet, and touched this, not with the palm, but with the back of the hand. Thus all the hands together could only have diminished the traction upon the dynamometer. Upon the desire being expressed to see this traction augment, it increased from 7½ pounds to 13 pounds. During all these experiments each of the medium's feet rested under the foot of her nearest neighbor to right or left.
Complete Levitation of the Table.
It was natural to conclude that if the table, in apparent contradiction to the law of gravity, was able to rise partly, it would be able to rise entirely from the floor. As a matter of fact, this is what happened. This levitation, one of the most frequent phenomena that occur in the experiments with Eusapia, stood a most satisfactory examination.
The phenomenon always materialized under the following conditions: the persons seated about the table place their hands on it, and form the chain; each hand of the medium is held by the adjacent hand of her two neighbors; each of her feet remains under the feet of her neighbor, who also press her knees with theirs. She is seated, as usual, at one of the small ends of the table, a position least favorable for a mechanical levitation. At the end of several minutes the table makes a side movement, rises first to the right, then to the left, and finally mounts off of its four feet straight into the air, and lies there horizontally (as if it were floating on a liquid), ordinarily at a height of from 4 to 8 inches (in exceptional cases from 24 to 27 inches); then falls back and rests on its four feet. It frequently remains in the air for several seconds, and while there also makes undulatory motions, during which the position of the feet under the table can be thoroughly examined. During the levitation the right hand of the medium often leaves the table, as well as that of her neighbor, and is held in the air above.
In order the better to observe this thing, we removed one by one the persons placed at the table, recognizing the truth that the chain formed by several persons was neither necessary for this phenomenon nor for others. Finally, we left only a single person with the medium, seated at her left. This person placed her foot upon Eusapia's two feet and one hand upon her knees, and held with her other hand the left hand of the medium. Eusapia's right hand was on the table, in full view,—though sometimes she held it in the air during the levitation.
