2. Under the same conditions, thought can be communicated directly, though unconsciously, from one individual to another.

As long as we were ignorant of any other facts than those resulting from a movement effected by contact with the fingers of the hand, in a way in which the mechanical action of the fingers became possible, the results of the experiments upon the table were always of difficult and doubtful interpretation. These results had to be necessarily based upon an estimate of the mechanical force exerted by the hands compared with the strength of the resistance to be overcome. But the mechanical force of the hands is difficult to measure exactly, under the conditions necessary to produce the phenomena.

Yet over and above that plan of work there remained two methods, of operation to employ.

_a._ So to dispose the apparatus employed that the movement to be produced shall be one that the mechanical action of the fingers could not compa.s.s.

_b._ To set up movements at a distance without any kind of contact.

The following were our first experiments:

A. _Mechanical action rendered impossible._ The first experiment attempted along this line gave wholly negative results. We suspended a table by a cord that pa.s.sed over two pulleys fixed in the ceiling and had a counter-weight attached to the free end. It was easy, by regulating this counterpoise, to balance in the air either the total weight of the table or only a fraction, more or less great, thereof.

As a matter of fact, the table hung almost in equilibrium with the weight, one only of its three legs touching the floor. The operators placed their hands upon the top surface. We acted at first in a circular direction, a disposition of the force the efficacy of which had been established by previous experiments. We then tried in vain to lift the table by detaching it from the floor. No positive result was obtained.

We had already (during the previous year) had a table suspended to a dynamometer, and the efforts of four mesmerizers were powerless to relieve the dynamometer of an appreciable fraction of the weight of the table.

But the conditions necessary for the production of the phenomena were still unknown to us, and, consequently, when the experiments tried led to negative results, we had to try others, without pressing too hastily for inferences and conclusions. It was thus that we secured the results which I am going to describe.

_Experiment with the Swinging Table._--We needed a piece of apparatus of such a kind that the mechanical action of the fingers would be rendered impossible. For this purpose we had a table made with a top about 33 inches in diameter, and a central trifurcated leg underneath. This table bore a close resemblance to the one which had served our purposes up to that time, and could turn like its predecessor. Still, the new table was capable of being transformed in a moment into a mechanism such as I shall now describe.

The summit of the tripod becomes the fulcrum of a lever of the first order which is able to balance freely in a vertical plane. This lever, whose two arms are equal to each other and to the radius of the table bears at one of its extremities the table-top, held by the edge, and, toward the other extremity, a counterpoise which just balances the weight of the table, but which can be modified at will. To the under side of the table-top is fastened a leg resting on the floor.

After the necessary preliminary rotations, the table is harnessed up in its second form. Equilibrium is first secured, then 3-5 of a pound is taken from the counterpoise. The force required to lift the top by its centre is then 4 ounces, and previous experiments have proved that the adherence of the fingers of the operators (the top was polished, and not varnished), together with the possible effects of elasticity, form a total lower than that figure. Yet the top is lifted by the action of the fingers placed lightly on its upper surface, at a certain distance from the edge. Then the counterpoise is diminished; the mechanical difficulty of lifting is augmented, yet still it takes place. The weight is again diminished, and more and more, up to the limit of the apparatus. The force necessary to lift the top is then 8 1-5 pounds, and the counterpoise has been relieved of 24 pounds; yet the levitation is easily accomplished. The number of the operators is gradually lessened from eleven to six. The difficulty goes on increasing, yet six operators still suffice; but five are not enough.

Six operators lift 9 1-3 pounds,--an average for each man of about 1-1/2 pounds.

We now possess, in the apparatus just described, a gauge or instrument of measurement.

B. The following movements were produced without contact:

The table on which were made the trials I witnessed has a diameter of 32 inches and weighs 31 pounds. An average tangential force of 4 2-5 pounds, which may be raised to 6 3-5 pounds, according to the greater or less inequalities of the floor, applied to the edge of the table, is necessary to give to it a movement of rotation. Ten is usually the number of persons who operate about this table.

In order to a.s.sure ourselves of the absence of all contact, we placed our eye on a level with the table in such a way as to see light between our fingers and the surface of the table, the fingers themselves remaining a little less than an inch above the top.

Usually, two persons would be observing at once. For instance, M.

Edmond Boissier was observing the legs of the table, while I was watching the top. Then we exchanged roles. Sometimes two persons took places at the extremities of one and the same diameter, the one opposite the other, for the purpose of watching the top of the table.

Several times we saw it move, although we could not detect the slightest touch by the fingers. According to my calculations, it would require the contact of at least 100 fingers, or the light pressure of thirty, acting voluntarily and fraudulently, to explain in terms of mechanics the movements we observed.

Much more frequently still we obtained balancings without contact, balancings which sometimes went so far as to tip the table entirely over. To explain in terms of mechanical movement the effects we observed, we should have to admit the involuntary contact of 84 fingers, or the light pressure of 25, or two hands acting with intent to deceive. But these suppositions, also, are not at all admissible.

Nevertheless, we always felt that someone might present the objection that it was difficult to observe these operations with precision, and we were constantly urging M. Gasparin to convince the doubters and sceptics in the matter of the non-contact of the fingers by means of some mechanical device. Out of this arose the last experiment made at that time, and the most conclusive of all. A light film of flour was almost instantaneously spread over the table by means of a sulphur bellows such as is used in vineyards. The movement of the chain of hands above the table set it whirling. Then the film of flour was examined and found to be inviolate from the touch of hands. Several repet.i.tions on different days always gave the same results.

Such are the princ.i.p.al facts which establish the reality of the phenomenon. Thury next takes up the more difficult investigation of courses.

_The Seat of the Force._--It is possible that the force which produces the phenomena is a general telluric force which is merely transmitted by the operators or set in action by them; or, possibly, the force resides in the operators themselves.

To decide this question, we had a large movable platform constructed which revolved on a perfectly vertical axis. Near the outer periphery of the platform stood four chairs, and there was a table at the centre. Four operators, experts in nervo-magnetic action, took their places on the chairs, and, placing their hands on the table in the centre, tried to give it circular movement by non-mechanical power. In fact, the table soon began to move. Then it was stopped and fastened to the platform by means of three screws. The effort exerted upon this table by the four magnetizers was such that, at the end of three-quarters of an hour of experimentation, the central supporting leg, was broken. Yet the movable platform did not turn. The tangential force required to mechanically move the empty platform was only a few grams; loaded with the four operators, 250 grams was necessary, applied about 28 inches from the centre. This figure would have been much less if it had been possible to distribute the weight of the operators uniformly.

The result of this experiment (of June 4, 1853) showed that the force which tends to make the table turn is in the individuals and not in the ground. For the force exerted upon the table tends to draw along the platform with it. If, then, the platform remains motionless, it must be that an equal and contrary force is exerted by the operators.

It is therefore in them that the base of the seat of the force resides. If, on the contrary, this force had emanated, wholly or in large part, from the ground, if it had been a force directly telluric, the platform would have turned, the effort which the table exerted upon it being no longer counterbalanced by an equal reaction proceeding from the individuals.

_Conditions of the Production and Action of the Force._--I have said that the conditions for the production of the force are little known.

In the absence of precise laws, I shall present what has been verified in a greater or less degree in the case of the three following points:

_a._ Conditions of action relative to the operators.

_b._ Conditions relative to the objects to be moved.

_c._ Conditions relative to the mode of action of the operators upon the objects to be moved.

THE WILL. The first and the most indispensable condition, according to M. Gasparin, is the will of the operator. "Without the will," he says, "we obtain nothing; we might sit there in chain twenty-four hours in succession without getting the slightest movement." Farther on, the author speaks, it is true, of unexpected movements different from those which the will prescribes; but it is evident that he is referring to a necessary combination of prescribed movements and external resistances, the effective movements being the _resultant_ of those that have been willed and of forces of resistance developed in external objects. In short, the will is always the prime mover and originator.

Nothing, it is true, in the experiments at Valleyres gave any authority for believing that it could be otherwise than this. But it is also certain that this purely negative result, or provisional generalization, deduced from a limited number of experiments,--cannot invalidate the results of experiments inconsistent with those, in case such should exist. In other words, the will may ordinarily be necessary, without always being so. Similarly, contact is ordinarily necessary, and _always_ has been so with a large number of operators, without, however, giving them the right to conclude that contact is the indispensable condition of the phenomenon, and that the different results obtained at Valleyres were only illusions or error.

Since we are dealing here with a point of capital importance, I shall take the liberty of stating with some detail circ.u.mstances which seem opposed to the thesis maintained by M. Gasparin. These facts, or data, have as guarantee the testimony of a man whom I should like to be able to name, because his scientific culture and his character are known of all men. It was in his house and under his eyes that the events took place which I am going to relate.

At the time when everyone was amusing himself with making tables turn and speak, or in directing the motions of lead-pencils, fixed in movable sockets, over sheets of paper, the children of the house amused themselves several times with this sport. At first, the responses obtained were such that you could see in them a reflex of the unconscious thought of the operators, a "dream of waking performers." Soon, however, the character of the replies seemed to change. It seemed as if what they revealed could hardly have emanated from the mind of the young interrogators. Finally, there was such an opposition to the commands given that M. N., uncertain as to the true nature of these manifestations in which a will different from the human will _seemed_ to appear, forbade their being called forth again.

From that time forth, sockets and table rested undisturbed.

A week had scarcely rolled by, after the events just narrated, when a child of the family, he who had formerly succeeded best in the table experiments, became the actor, or the instrument, in strange phenomena. The boy was receiving a piano-lesson, when a low noise sounded in the instrument, and it was shaken and displaced in such a way that pupil and teacher closed it in haste and left the room. On the next day, M. N., who had been informed of what had happened, was present at the lesson, given at the same time,--namely, when the dusk was coming on. At the end of five or ten minutes he heard a noise in the piano difficult to define, but which was certainly the kind of sound one would expect a musical instrument to produce. There was something about it musical and metallic. Soon after, the two front legs of the piano (which weighed over six hundred and sixty pounds) were lifted up a little from the floor. M. N. went to one end of the instrument and tried to lift it. At one time it had its ordinary weight, which was more than the strength of M. N. could manage; at another, it seemed as if it had no longer any weight at all, and opposed not the least resistance to his efforts. Since the interior noises were becoming more and more violent, the lesson was brought to a close, for fear the instrument might suffer some damage. The lesson was changed to the morning and given in another room situated on the ground floor. The same phenomena took place, and the piano, which was lighter than the one up-stairs, was lifted up much more; that is to say, to a height of several inches. M. N. and a young man nineteen years old tried leaning with all their might on the corners of the piano which were rising. Then one of two things happened: either their resistance was in vain, and the piano continued to rise, or else the music-stool on which the child sat moved rapidly back as if pushed or jerked.

If occurrences like that had only taken place once we might think that the child or the persons present were laboring under some illusion.

But they were repeated a great number of times, for a fortnight, in the presence of different witnesses. Then, one day, a violent manifestation took place, and thenceforth no unusual event occurred in the house. At first, it was in the morning and in the evening that these perturbations manifested themselves; then, invariably at any and all hours, they occurred every time the child took his seat at the piano, after five or ten minutes of playing. The phenomena happened only with this boy, although there were others present (musicians); and it made no difference which of the pianos in the house he used.

I saw these instruments. The smaller, on the ground floor, is a rectangular horizontal piano. According to my calculations, a force of about 165 pounds applied to the edge of the case, beneath the key-board, is necessary to lift this piano as it was lifted by the unknown force. The instrument in the first story of the house is a heavy Erard piano, weighing, with the packing-box in which it was sent, 812 pounds, as stated in the way-bill, which I myself saw.

According to my approximate calculations a pressure of 440 pounds is required to lift this piano, under the same conditions as the first was lifted.

I do not think that anyone will be tempted to attribute to the direct muscular effort of a child eleven years old the lifting up a weight of 440 pounds.[57] A lady who had attributed the effect produced to the action of the knees pa.s.sed her own hand between the edge of the piano and the knees of the child, and was thus able to convince herself that her explanation had no foundation in fact. Even when the child got upon his knees upon the piano-stool to play, he did not find that the perturbations he dreaded ceased any the more.

These authenticated facts of Professor Thury are at once precise and formidable. What! two pianos rise from the floor and jump about! What do the physicists, the chemists, the learned pedants in office need, then, to arouse them from their torpor and make them shake their ears and open their eyes? What shall be done to remove their n.o.ble and pharisaical indolence?

But, happen what may, no one is occupying himself with the fascinating problem as stated, except scattered investigators who are freed from the fear of ridicule and are aware of the exact value of the human race, in large and small, and the worth of its judgments.

M. Thury next discusses the explanation based on "the will."

Did this boy (he says) _will_ what took place, as the theory of M. de Gasparin would require us to admit? According to the boy"s testimony, which we believe to be wholly true, he did not will it; he seemed to be visibly annoyed by what occurred; it disturbed his custom of industriously practicing his lesson and offended his taste for regularity and order, a thing well known to his intimates. My personal conviction is that we positively cannot admit, in the case of this lad, a conscious will, a settled design, to produce these strange occurrences. But it is known that sometimes we have a double personality, and one of them converses with the other (as in dreams); that our nature then unconsciously desires what it does not will, and that between will and desire there is only a difference in degree rather than in kind. It would be necessary to have recourse to explanations of this kind,--too subtle, perhaps,--in order to square these piano-facts with the theory of M. Gasparin; and it would still be necessary to modify and enlarge the facts if you admit that _even unconscious desire_ suffices, in the absence of the expressed will.

There is, then, reason for doubt on this essential point. That is the sole deduction that I wish to draw from the events I have related.

This levitation, equivalent to an effort exerted of 440 pounds, has its scientific value. But how could the will, conscious or unconscious, lift a piece of furniture of that weight? By an unknown force which we are obliged to recognize.

_Preliminary Action._--Power is developed by action. The rotations prepare for the tippings and the levitations. The rotations and the tippings, with contact, seem to develop the force necessary to produce the rotations and tippings without contact. In their turn, the rotations and the tippings without contact prepare for the production of true levitations, such as those of the swinging table; and the persons who have this latent force awaked in them are better fitted to appeal to it a second time.

There is, then, a gradual preparation required, at least for the majority of operators. Does this preparation consist in a modification that takes place in the operator, or in the inert body on which he acts, or in both? In order to resolve this problem, experimenters who had been practicing at one table went over to another, operating on which they found their full power unabated. The preparation therefore consists in a modification that takes place in the individuals, and not in the inert body.[58] This modification occurring in individuals is dissipated rather rapidly, especially when the chain of experimenters is broken.

_Inner Development of the Operators._--It is only after a certain period of waiting that the operators, who have not so far acted, cause even the easiest movement,--that of rotation with contact. It is during this time that the force, or the conditions determining the manifestation of the force, develop themselves. From that time on, the developed force has nothing to do but to increase. That which takes place, therefore, in this time of waiting, is a very important thing to be considered. We already know that it is the operators themselves who are modified. But what is it that takes place within them?

It must be that a kind of activity is set up in the organism, an activity which ordinarily requires the intervention of the will. This activity, this work, is accompanied by a certain fatigue. The action is not aroused in all operators with equal ease and promptness. There are even persons (the author estimates their number at one in ten) in whom it appears that it cannot be produced at all.

In the midst of this great diversity of natural apt.i.tudes, it is observed that children "can secure obedience from the table just like grown folks." Nevertheless, children do not magnetize. Thus, although several facts seem to show that magnetizers (or mesmerizers) have frequently a strong power over the tables, yet one cannot admit the ident.i.ty of magnetic power and power over the tables; the one is not the measure of the other. Only, the magnetic power would const.i.tute (or presume) a favorable subjective condition.
