It is a question of positive fact that I wish to solve. The theory will come later. To prove that the phenomenon of turning tables is real and of a purely physical nature; that it can neither be explained by the mechanical action of our muscles nor by the mysterious action of spirits,—such is my thesis. It is my wish to state it with precision and circumscribe its limits here at the very start. I confess I find some satisfaction in meeting with unanswerable proofs the sarcasms of people who find it easier to mock than to examine. I am well aware that we have got to put up with that. No new truth becomes evident without having been first ridiculed. But it is none the less agreeable to reach the moment when things assume their legitimate place, and when rÔles cease to be inverted. This moment might have been long in coming. For a long time I feared that table-phenomena would not admit of a definite scientific demonstration; that, while they inspired absolute certainty in the minds of the operators and witnesses at first hand, they would not furnish irrefutable arguments to the public. In the presence of bare possibilities, each person would be free to cherish his own particular opinion; we should have had believers and sceptics. The classification would have taken place in virtue of tendencies rather than by reason of one's knowledge or ignorance of the facts. Some, in the agreeable sensation of their intellectual superiority, would have carried their head very high, and others would have abandoned themselves in despair to the current superstitions of the day. The truth incompletely demonstrated would have been treated as a lie, and, what is worse, would have ended by becoming such.

But thank God! it will not be so now. Our meetings were real and formal sÉances, to which the best hours of the day were given. The results, verified with the most minute care, were embodied in formal and official declarations. I have these procÈs-verbaux before me now, and it seems to me that I could not do better than to take up one after another and extract from each the interesting observations it may contain. I shall thus follow the method of certain historians, and relate the truth rather than systematize it. The reader will, as it were, follow us step by step. He will examine and check my various assertions by comparing them; he will form his own conviction, and will judge whether my proofs have that character of frequent occurrence, of persistency, of progressive development which false discoveries, based upon some fortuitous and poorly described coincidence, never have.

Only those have an invincible conviction (writes Count de Gasparin) who have participated in sÉance studies frequently and directly, who have felt under their very fingers the production of those peculiar movements which the action of our muscles cannot imitate. They know the limitations of their powers and where to stop. For they have seen the table refuse to rotate at all, in spite of the impatience of the investigators, and in spite of their clamorous appeals. Then again, they have been present when it started to move so gently, so softly and spontaneously started, it can be said, under fingers which hardly touched it. They have at times seen the legs of the table (riveted by some enchantment to the floor) refuse to budge on any terms, in spite of the incitement and coaxing of those who composed the chain. On other occasions they have seen the same table-legs perform levitations that were so free and energetic that they anticipated the hands, got the start of the orders, and executed the thoughts almost before they were conceived, and with an energy well-nigh terrifying. They have heard with their own ears stunning raps and gentle raps, the one threatening to break the table, the others of such incredible fineness and delicacy that one could scarcely catch the sounds, and none of us could in any degree imitate them. They have remarked that the force of the levitations is not diminished when the sitters are removed from the side of the table that is to form the fulcrum. They have themselves commanded the table to lift that one of its legs over which rest the only hands that compose that portion of the chain still remaining, and the leg has risen as often and as high as they wished. They have observed the table in its dances when it beats the measure with one foot or with two; when it reproduces exactly the rhythm of the music that has just been sung; when, yielding in the most comic way to the invitation to dance the minuet, it takes on grandmotherly airs, sedately makes a half turn, curtsies, and then comes forward turning the other side! The manner in which the events took place told the experimenters more than the events themselves. They were in contact with a reality which soon made itself understood.

The persevering experiments we had made before the 20th of September had already given us proof of two principal things,—the levitation of a weight that the muscular action of the operators was powerless to move, and the reproduction of numbers by mind reading.

SÉance of September 20

Some one proposed the experiment which consists in causing a table to rotate and give raps while it has on it a man weighing say a hundred and ninety pounds. We accordingly placed such a man on the table, and the twelve experimenters, in chain, applied their fingers to it.

The success was complete: the table turned, and rapped several strokes. Then it rose up entirely off the floor in such a way as to upset the person who was upon it. Let me be permitted here, in passing, to make a general remark. We had already had numerous meetings. Our experimenters, among whom were several young ladies of delicate physique, had worked with very unusual perseverance and energy. Their bodily fatigue at the end of each sitting was naturally very great. It seems as if we should therefore have expected some nervous collapses more or less grave, to show themselves among us. If explanations based upon involuntary acts performed in a state of extraordinary excitement had the least foundation in fact, we should have had trances, almost possessions, and, at any rate, nervous attacks. Now, in spite of the exciting and noisy character of our meetings, it did not happen, in five months time, that any one of us experienced a single moment of indisposition or sickness of any kind. We learned something more: when a person is in a state of nervous tension, he or she becomes positively unfit to act upon the table. It must be handled cheerfully, lightly, and deftly, with confidence and authority, but without passion. This is so true that the moment I took too much interest in things I ceased to obtain obedience. If, on account of public discussions in which I had been engaged, I chanced to desire success too ardently and to grow impatient over delay, I had no longer any control over the table; it remain inert.

SÉance of September 24

We began pretty poorly, and were almost inclined to think that the net result of the day's experiments would be limited to the two following observations, which have their value, to tell the truth, and which our experience has always confirmed: First, there are days when nothing can be done, nothing prospers, although the sitters are as numerous, as strong, and as excited as ever,—which proves that the movements of the table are not obtained by fraud or by the involuntary pressure of the muscles. Second, there are persons (those among others who are sickly or fatigued) whose presence in the chain is not only of no use, but even detrimental. Destitute themselves of the fluidic force, they seem, besides, to hinder its circulation and transmission. Their good will, their faith in the table are of no avail; as long as they are there the rotations are feeble, the levitations spiritless, the drafts drawn on the table are not honored; that one of its feet facing them is especially struck with paralysis. Beg them to retire, and immediately the vitality appears again and everything succeeds as if by magic. Indeed, it was only after we had taken this course that we finally obtained the free and energetic movements to which we had been accustomed. We had become quite discouraged; but when the purging of which I have just spoken took place, lo, what a change! Nothing seems difficult to us. Even those who (like myself) ordinarily have only mediocre success, now think of numbers and make the table rap them out with complete success, or with the slight imperfection (that frequently occurs) of a tap too many, owing to the delay in giving the mental order to stop the taps.

Seeing that everything was going according to our wish, and having decided to try the impossible, we next undertake an experiment which marks our entrance into a wholly new phase of the study and places our former experimental demonstrations under the guarantee of a positively irrefutable demonstration. We are going to leave probability behind and dwell with evidence. We are going to make the table move without touching it. And this is how we succeeded that first time:

At the moment when the table was whirling with a powerful and irresistible rotation, at a given signal we all lifted our fingers. Then keeping our hands united by means of the little fingers, and continuing to form the chain at a height of say an eighth or a quarter of an inch above the table, we continued our circular movement. To our great surprise the table did the same; it made in this way three or four turns! We could scarcely believe our good fortune; the by-standers (witnesses) could not keep from clapping their hands. And the way in which the rotation took place was as remarkable as the rotation itself. Once or twice the table stopped following us because the little accidents and interruptions of our march had withdrawn our fingers from their regular distance from the top of the table. Once or twice the table had come to life again—if I may so express myself—when the turning chain had again got into the right relation with it. We all had the feeling that each hand had carried along in its course that portion of the table immediately beneath it.

SÉance of September 29

We were naturally impatient to submit rotation without contact to a new test. In the confusion of the first success we forgot to renew and vary this decisive experiment. When we got to thinking about it afterwards we saw that it behooved us to do the thing over again with more care and in the presence of new witnesses; that it was, above all, important to produce the movement and not merely to continue it, and to produce it in the form of levitations instead of limiting it to rotations. Such was the program of our meeting of September 29. Never was program carried out with greater precision. As a preliminary, we repeated our successful feat of the 24th. While the table was rotating rapidly, the interlocked hands were lifted from it, though continuing to turn above it and form the chain. The table followed, making now one or two revolutions, and now a half or a quarter turn only. The success, more or less prolonged, was certain. We confirmed it several times. But some one might say that, the table being already in motion, the momentum carried it along mechanically while we imagined it was yielding to our fluidic force. The objection was absurd, and we would have challenged anybody to obtain a single quarter of a turn without forming the chain, however rapid might have been the rotation imparted. Above all, would we have challenged anyone to renew its motion when it had been for an instant suspended. However, it is well in such cases to forestall even absurd objections, however little of plausibility they may have. And this particular objection might seem plausible to the inattentive man. It was imperative, then, that we should produce rotation starting from a state of complete inertia. This we did. The table being as motionless as we were, the chain of hands parted from it and began to turn slowly at a height of about three-eighths of an inch above its edge. In a moment the table made a slight movement, and each of us striving to draw along by his will that part situated under his own fingers, we succeeded in drawing the disk in our train. The details that followed resembled those of the preceding case. There is such difficulty in maintaining the chain in the air without breaking it, in keeping it near the border of the table without going too quick and thus destroying the harmonious relation established, that it often happens that the rotation stops after a turn or a half-turn. Yet it is sometimes prolonged during three or even four revolutions. We expected to encounter still greater obstacles when we should undertake levitation without contact. But the matter turned out quite otherwise. This is easily explained when we remember that in this ease there is no circular movement and it is much easier to maintain the normal position of the hands above the table. The chain, then, being formed at a distance of an eighth of an inch or so above the round top of the table, we ordered one of its legs to lift itself up, and it did so.

We were highly delighted, and repeated this pretty experiment many times. Without touching it in any way, we ordered the whole table to rise into the air, and to resist the witnesses, who had to put forth effort to bring it down to the floor. We commanded it to turn bottom side up, and it fell over with its feet in the air, although we never touched it with our fingers, but kept them in advance of it as it fell, at the distance agreed upon.

Such were the essential results of this meeting. They are such that I hesitate to mention in the same connection incidents of secondary importance.

I will only say, in passing, that the sÉance was very discouraging at the start; for, not only was it found necessary to remove certain new operators, but several of the old ones did not bring to it their usual high spirits. The table responded poorly; raps were made faintly and as if with reluctance; the telepathic reading of numbers did not succeed. Then we took a resolution from which we derived much benefit: we persevered, and persevered gaily; we sang, we made the table dance; we gave up all thoughts of new experiments and persisted in easy and amusing ones. After a while conditions changed; the table fairly bounded, and hardly waited for our orders; we were now in condition to try more serious things.

SÉance of October 7

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.

Let us turn again to the finest of all demonstrations, that of levitation without contact. We began by performing it three times. Then, since it was thought by some that the inspection of the witnesses could be carried on in a surer way in the case of a small table than in that of a large one, and with five operators more certainly than with ten, we had a plain deal centre-table brought which the chain, reduced by half, sufficed to put in rotation. Then the hands were lifted, and, contact with the table being entirely broken, it rose seven times into the air at our command.

SÉance of October 8

Two circumstances occurred to confirm the results we had obtained in preceding sÉances. Among the numbers selected for the thought-test the roguery of one of the witnesses had placed a zero, and the leg selected by him to respond was at the left of the operator and beyond the reach of his muscular action. Now, the command having been given to the leg and no action resulting, we were all feeling disconsolate, being convinced that our weakness that day was so great that we were not going to obtain even simple levitations. I affirm most emphatically that if movement had ever been imparted by an experimenter to a table leg, it would have appeared at that moment. Our nerves were in an exalted state and our impatience was at its height. Yet no movement of the table took place, and we were consequently all the more solaced when we learned that the figure communicated had been a cipher.

Movement without contact was accomplished twice.

To our experiment of a table that gave raps while having a man upon it, it had been objected that this man might lend his aid to the movement, and even incite it in part. Determined to seek out the truth with the most anxious care, we had recognized a certain plausibility in this objection, and had decided to meet it fairly. The being who was living, intelligent, and consequently suspected must be replaced by an inert weight. Buckets filled with sand must be placed in the precise centre of the table, which should then be called on to exhibit its skill.

But the day was badly chosen. After we had placed on the table two buckets, one upon the other, both weighing in all 143 pounds, it was discovered that we were unable to produce the levitation. It was necessary for us to content ourselves with continuing them in circular movement after they had been started. The buckets were removed, the table was set in motion, and the buckets replaced while the movement was at its height. They did not arrest it in the least, but were carried around with such force that the sand flew out on all sides.

The remainder of the sitting was given up to an investigation of the subject of (alleged) divination, or guessing.

When the table was asked to guess something known to one of the members of the chain, it pretty frequently and quite naturally happened that it guessed it. It is the case of thought-reading by numbers,—nothing more, nothing less.

When it is asked to guess a thing known to a member of the company who does not form at the time a part of the chain, it happens sometimes that it guesses it. But the person in question must be endowed with great fluidic power and be able to exercise it at a distance. We did not ourselves obtain anything like this; but others have succeded, and their testimony seems too well established to be called in question.

Up to the present moment, it is plain, there is not the least trace of divination. It is fluidic action, near-by or distant.

If the tables divine, if they think, if there are spirits, we ought to get decisive responses in the case where no one knows the facts, either in the chain or out of the chain. The problem thus stated, the solution is not difficult.

Take a book. Do not open it, but invite the table to read the first line of the page you will designate,—say page 162 or page 354. The table will not flinch: it will rap, and will compose words for you. It was thus, at least, that it always acted with us. At any rate, one thing is certain, that neither here nor elsewhere, has any spirit, however cunning, read, this simple line; nor will it be able in the future to do so. I recommend the experiment to the partisans of spirit evocations.

As to the test of pieces of money in a purse, hours, playing-cards etc., the tables betake themselves to a strict calculation of probabilities; they guess just as much as you do, or as I do. Inasmuch as it is a question of small numbers of which one can form in advance an approximate idea, the range of possible combinations is not very extensive. The mind fixes upon a number which has a fairly good chance of being the true one, and the proportion between the failures of the table and its successes is in such a case just what it would be apart from all question of miraculous divination.

SÉance of November 9

Before entering upon the description of this sitting,—a very remarkable one,—I will say that neither the thermometer nor the mariners' compass have furnished the slightest indication of anything interesting. I thought I ought to note this, in passing, to show to the reader that we did not neglect to employ instruments which seemed likely to put us in the way of obtaining a scientific explanation. In general, I pass by that phase of our work, as well as the different trials which remained merely trials, and did not lead to any positive results.

Our first care was to renew the experiment of the levitation of an inert weight. It was agreed among us this time that we would always start from the state of absolute immobility in the object: we wanted to produce movement, not to continue it.

The centre of the table, then, having been fixed with nice precision, a first tub of sand, weighing 46 pounds, was placed upon it. The legs easily rose from the floor when they got the order.A second tub, weighing 42 pounds, was next placed in the middle of the other. They were both lifted—less easily, but very neatly and clearly.

Then a third tub, smaller, and weighing 28? pounds, was placed on top of the two others. The levitations took place.

We had still further got ready enormous stones weighing altogether 48½ pounds. They were placed on the third tub. After rather long hesitation, the table lifted several times in succession each of its three legs. It lifted them with a force, a decision, an Élan, which surprised us. But its strength, already put to so many proofs, could not resist this last one. Bending under the powerful swaying motion imparted by the total mass of 165 pounds, it suddenly broke down, and its massive centre-post was split from top to bottom—to the great peril of the operators on the side of whom the entire load rolled off.

I shall not stop to comment on such an experiment. It answers all demands. Our united muscular force would not have sufficed to determine the movements that took place. A mass of inert matter free from the suspicion of being obliging, had replaced the person whose complicity was held in suspicion. Finally, when the three legs had been lifted, each in turn, critics no longer had as a resource the insinuation that we had caused the weight to be laid more on one side than on the other.

Inasmuch as our poor table had been wounded on the field of honor and could not be repaired on the spot, we got a new one which much resembled it. But it was a little larger and a little lighter.

The interesting point was to be settled whether we were going to be obliged to wait for it to be charged with the psycho-physical fluid. The occasion was a famous one for solving this important problem: Where does the fluid reside?—in the operators or in the piece of furniture. The solution was as prompt as it was decisive. Scarcely had our hands, in chains, been placed upon this second table than it began to revolve with the most unexpected and the most comic rapidity! Evidently, the fluid was in us, and we were free to apply it in succession to different tables.

We lost no time. In the mood in which we then were, movement without contact must succeed better than ever. Nor did we deceive ourselves in so thinking. We first developed rotations without contact to the number of five or six.

As to levitations without contact, we discovered a method of proceeding that renders their success easier. The chain, formed a few millimetres above the top disk, is arranged so as to go in the direction in which the movement is to take place; the hands the nearest to the leg called on to rise are outside of and beyond the top; they draw near and pass gradually by, while the hands that are opposite, and which had at first advanced toward the same leg, move away from it while they attract it. It is during this progression of the chain, while all our wills are fixed upon a particular spot on the wood, and when the orders to levitate are forcibly given, that the foot quits the ground and the table-top follows the hands,—to the point of upsetting, if one did not keep hold of it.

This levitation without contact was produced about thirty times. We produced it by each of the three legs in succession, in order to remove every pretext for criticism. Moreover, we watched the hands with scrupulous care. If the reader will please observe that this surveillance was exercised during thirty operations without detecting the slightest contact, I think it will be concluded that the reality is henceforth placed beyond all doubt.

SÉance of November 21

The chief characteristic of this sÉance was the absence of that one of our number who exercised the greatest authority at the table.[52] In working without her we were put in a position to establish two things: first, that one cannot with impunity do without an extraordinary gifted experimenter; and, second, that one can, nevertheless, do without him or her, if it is absolutely necessary, and that success, although less brilliant in this case, is not impossible. I call special attention to this last point, as well as to the frequent modifications of our personnel, for the benefit of suspicious persons who, not knowing the mental worth of the persons in question, might be disposed to place to the account of their dexterity the results to which they essentially contribute. The psycho-physical working power of a "sensitive" table-turner is of a mixed nature: a resolute posture and a circular movement are not sufficient to give birth to it. Besides this, and above all, there is needed the will.

Our will having at last asserted itself, and muscular pressure having yielded its place to the pressure of commands, the fluidic rotation arrives, after five or six minutes of concentration of our thoughts. We felt, indeed, keenly that some important person was lacking and that we did not possess our usual power. However, we were determined to succeed, even at the price of greater mental fatigue.

So we took up boldly our most difficult feat; namely, movements without contact. Rotations without touch were obtained thrice. I should add that they were very incomplete,—a quarter of a turn, or a half-turn at most.

As to levitations without touch our success was more decisive; but it was purchased at the price of a very considerable expenditure of force. After each levitation we had to rest, and, when we had reached No. 9 we were absolutely obliged to stop, overcome with fatigue. One must have had personal knowledge of such experiments to understand what drafts they make upon one's attention and energy, and at what point it is indispensible to will, and to will peremptorily, that such and such a knot of wood in the table shall follow the opened fingers that are alluring it at a distance.

But be that as it may, our attempt was crowned with success, and we could end the sitting with less exhausting exercises.

The idea came to us then and there to try our powers on a large table with four legs. It had often been claimed that three-legged centre-tables alone would respond to our manipulations. It was time to furnish undeniable proof to the contrary. So we took a table three feet five inches in diameter, a folding half of which (independent of the leg that supports it when it is raised) can be turned up at will.

Scarcely were our fingers in place than the table began a rotation with noisy bustle, the sprightliness of which surprised us. It thus showed that tables with four legs were no more refractory than others. In addition to this, it furnished a new argument in favor of one of our former observations,—that the fluid is in the persons and not in the tables. In fact the movement of the large table took place almost immediately, and before it could be considered as charged with fluid.

The next task before us was to make it give raps with its different legs. We began with those fastened to one half of the top, three in number. They rose from the floor two at a time with such force that at the end of a moment one of the casters flew to pieces.[53] Now it is difficult to form an idea of the intensity which a fraudulent action of the fingers must have acquired in order to exercise a leverage upon so heavy a table, and launch it into the air to such a height.

There remained the leg of the table which was independent of the top. We thought it would obey as well as the others. But no! In vain did we pour out the most prodigal and pressing invitations: it was never willing to rise, either along with its right-hand neighbor or with its neighbor on the left. Our next thought was that this was due to the persons placed near it, and certain members of the chain changed seats. In vain! All combinations failed one after another.

We drew great deductions from this circumstance. But since it was refuted later, when the contumacious leg yielded perfect obedience at another meeting, I will not take the public into our confidence by a display of our reasonings on the subject. I will only ask that two things be noted; first, the care we took to verify many times the phenomena before affirming them; and, second, that we have here once more a fine refutation of the critics who assert that muscular action can explain everything. If this were so, why did not muscular action lift the free leg as well as those fastened tight to the table? It could have done so just as easily; and yet for some unknown reason, but one evidently foreign to the laws of mechanics, only the attached legs consented to move.

SÉance of November 27

We were in full muster; but two or three of the operators were slightly indisposed. On the whole, whatever was the cause, the occasion was scarcely remarkable for anything except the almost total absence of fluidic power. For a single moment we had a little of it. A half-hour of action and two hours and a half of inertia—this was our net result.

Nothing was more lamentable, and at the same time more curious, than to see us about the different tables, passing from one to another, enjoining them to do the most elementary things, and only obtaining a weak and languid rotation, which soon stopped altogether.

SÉance of December 2

I should have been vexed to have to close my recital with so dull and spiritless a record as the preceding one. By good fortune the last of our reports gives me the right to leave a totally different impression on the reader's mind.

We were in fine temper. Perhaps the beautiful weather helped. It is not the first time I have noticed this. What is certain is that the very same persons who, on November 27, had only a half-hour of success and had passed the rest of the sitting in beseeching in vain for anything better than poor abortive rotations or faint raps, to-day governed the table with an authority, a quickness, and, if I may so put it, an elasticity of bearing that left nothing to be desired.

The large table with four legs was set in motion. And this time, the ease with which the free leg lifted its share of the table proved that we were right in not drawing too definite conclusions from its former refusal. Every time that we tried to lift without contact that part of the table the farthest removed from myself I felt the table-leg nearest me gradually approach and press against my leg. Struck with this occurrence, which took place several times I drew the conclusion that the table was gliding forward, not having enough force to rise. We were, then, exercising a perceptible influence on this large table without touching it in any way.

In order the better to assure myself of it, I left the chain and observed the movement of the feet of the table on the floor. It ranged from fractions of an inch to several inches. When we then tried to turn up without contact the folding leaf of a gaming-table covered with cloth, we obtained the same result: the folding leaf would not yield to our influence, but the entire table advanced in the direction of the prescribed movement. Now, I ought to add that the gliding was not at all easy, for the floor of our room was rough and uneven.

It is interesting to note in this connection the moment when this gliding movement ordinarily begins. It occurs at precisely the same time that the levitation without contact takes place when that manifestation is in process. When the portion of the chain which is pushing on has just advanced beyond the side of the table-top, where it begins to turn, and when that portion of the chain that is pulling has just crossed the middle point in its recession, then the ascensional movement—or, in default of that, the gliding motion—manifests itself. Our fluidic power is then at its maximum, precisely at the instant when our mechanical power is at its minimum, when the hands that are pushing have ceased to act (supposing the case of fraud) and when the hands that pull are powerless to act.

Let us now revert to our ordinary table. We tried to produce rotations and levitations without contact, and had complete success.
