In ordinary seances, the table used to be raised to a lesser height; perhaps because we were seated, and could not therefore accompany it very far. As a rule, the levitation was preceded by oscillations; the table raised itself first on one side, then on the other, and finally left the ground. Very often Eusapia, holding her neighbours’ hands, would abandon all contact with the table, and make several passes above it, when the table would rise, apparently of its own accord.

I have only obtained parakinetic levitation under really good conditions with Eusapia. I have observed more decided movements without contact with other mediums, but they have not given me levitations properly so-called. I have once or twice obtained defective levitations with a non-professional medium. The table drew near to her of its own accord, and raised itself while touching her dress. This fact occurred in the light, but the conditions under which I observed it were imperfect. I may say the same thing of some levitations I obtained at Bordeaux with rather an interesting professional medium; these levitations took place in total obscurity, which rendered good conditions of control impossible; besides no one held the medium’s hands and feet, as had been done with Eusapia.

In a series of experiments which gave me some results worthy of careful examination, I obtained the levitation of the table under slightly better conditions. But some of the sitters cheated so barefacedly, that I do not consider I ought to take any serious notice of the parakinetic movements I witnessed there; although I have the impression that everything was not simulated which happened in this group. The unsatisfactory conditions under which I made this series of experiments led me to discontinue them.

I consider that the levitation of the table, even with the contact of the hands, is a difficult phenomenon to obtain under good conditions of observation. Up to the present, Eusapia Paladino is, I repeat, the only medium with whom I have been able to verify the phenomenon in a satisfactory manner.

Her method is similar to the one I indicated and recommended to my readers. Phenomena are often forthcoming when she raises her hand above the table. Although I do not consider myself authorised to affirm the reality of the effect this method appears to exercise upon the phenomenon of levitation, I indicate it because the positive results, which similar practices have given me in telekinetic experiments, lead me to think it may also answer for parakinetic experiments. Let me briefly explain this method. When the experimenters have their hands on the table, and the latter begins to sway about from side to side as if it were trying to raise itself, one of the sitters puts his hand above the table, palm downwards, and approaches it to within two or three centimetres of the top. Then he raises it very gently; while doing this, the levitation sometimes takes place as though the hand drew the table after it.

I recommend experimenting with as much light as possible. We must not forget that nothing is easier to simulate than a parakinetic levitation. Force of habit will soon teach us how to recognise fraudulent phenomena of this kind, but it is nevertheless important to know beforehand the principal systems of cheating. With the reader’s permission I will indicate them.

The position, which the experimenters are obliged to assume around the table when they are seated, has the consequence of almost completely hiding their feet. As soon as the lights are lowered, it is nearly impossible to exercise that mutual control which it is indispensable should be exercised. Now, when the hands rest a little forcibly on the table, it is very easy, especially with a light table, to glide the point of a shoe under one of the legs of the table and to raise it above the ground. This manœuvre is all the easier, as the swaying of the table from side to side permits one to effect the movement, without much fear of detection. Needless to say that hooks attached to the wrist, or specially contrived bracelets, also permit of raising and holding the table in the air. But it is easy to protect oneself against fraud of this nature. Let every one stand up and join hands in the centre of the table; the kind of fraud I indicate will then be impossible. I myself have often obtained fine levitations in this way, but unfortunately in obscurity.

I will point out still another fraudulent process practised at times by professional mediums. It consists in the following manœuvre. The medium places himself at the narrow end of a table,—in preference a rectangular one—he promotes various oscillations, and when he has succeeded in raising the end opposite to him, he spreads out his legs in such a way as to exercise a strong hold over the feet of the table, between which he is sitting. Once this pressure is exercised, there is nothing more for the medium to do, in order to obtain a levitation, than to lean his hands heavily on the table. It is easy to understand how the table, maintained in position by the trickster’s knees, executes a rotatory movement around an axis the points of which are fixed by the pressure of the knees; consequently the table, becoming parallel with the ground, appears to be abnormally levitated. This simulation can be successfully realised, even when some one is seated on a chair on top of the table; under the pretence of offering a better condition of control, the medium takes the hands of the person on the table, and finds in him the point of support required to promote the rotation of the table around its axis. We should keep this kind of fraud before the mind’s eye when seeking to obtain levitations, especially if operating in obscurity, for then this trick is most easy of execution.

Once again, I cannot too strongly warn experimenters against dark seances: they are absolutely worthless when paranormal phenomena are required. These ought to be obtained in full light; under such conditions the levitation of the table is a verifiable phenomenon.
