A long meeting, and very fatiguing. It was principally devoted to the trial of various mechanical devices which had no success whatever,--such as metal rings; frameworks of canvas or of paper placed upon the table; plates on pivots and spring-keys. Whether the sight of all this gear hindered the radiation of the fluidic force from the operators, whether the contrivances themselves stopped its circulation in the table, or whether, in fine, the natural conditions of the phenomenon were disturbed in some other way, it is certain that the results amounted to nothing or were doubtful. One new experiment succeeded. A plate turning on a pivot held a tub. I filled this tub with water, and two of my collaborators and I plunged our hands into it. We formed the chain and began a circular walk, being careful not to touch the tub. This at once imitated our movement. We repeated the thing several times in succession. Since it might be supposed that the impulse given to the water would suffice to set in motion a tub resting on so delicately balanced a plate, we at once proceeded to prove the contrary. The water was given a circular whirl causing it to move with much greater rapidity than when we formed the chain; but the tub moved not a peg. Undoubtedly the point remains to be considered whether one of us three did not touch the inside of the tub and so determine its movement. To that I reply, first, that the way in which our hands were held in the water obviously proves that none of our fingers could really touch bottom; secondly, that, taking pains as we did to form the chain at the centre, it would have been scarcely less difficult for us to touch the vertical sides of the tub. And yet, the doubt being not wholly inadmissible, I class this experiment among those of which I do not purpose to make any use. I wish to show that I am hard to please in the matter of evidence. The proof which the rapping of numbers by mind-reading furnishes has always seemed to be one of the most convincing. In the sitting I am describing, it had this special feature, that each of the ten operators in turn received the communication of a number in writing, the others having their eyes shut. Now, in the whole ten, one alone failed to obtain perfect obedience from the table-leg which had been assigned to him by very suspicious witnesses, or by-standers. If my readers will reflect carefully they will see that the combinations of movements communicated and of cheating tricks which such a solid result as this would require passes far beyond the bounds of admissible things. To justify it the objector must invent a miracle much more astounding than ours.
