The medium’s sensations are generally much more accentuated than those of the sitters. Sensitives say, they distinctly feel the passage and the interruption of the current; I think it is a question of degree: their sensations differ from the sensations of other experimenters only in degree. There is, nevertheless, a category of sensations, which is almost exclusively felt by the medium when a fairly strong movement is forthcoming: this is the sensation of a sudden emission of force. One of the most intelligent mediums I have come across describes it, as a sensation of cramp in the epigastric region; it seems to him at times as though he were on the verge of fainting. I have indicated a similar sensation, which I myself once felt during a levitation obtained with Eusapia Paladino. I felt the same thing on other occasions, but not with the same intensity. I remember, for example, an experiment made under the following conditions: We were holding a seance on a winter’s evening; the light on this occasion, though feeble, was sufficient. We had covered the table with a woollen cloth which fell over our knees, and protected us slightly from the cold. Upon the seance table we had placed a smaller one upside down. We touched the edge of the smaller table. Having noticed that the small table appeared to be trying to raise itself on one side, I endeavoured to increase the amplitude of the movement by violently contracting the muscles of my arms and legs. While I made this intense effort, we saw the little table slowly lean forward, and turn itself over without coming into any contact whatever with ourselves. When the phenomenon was accomplished, I felt suddenly very tired. It is possible, that the cause of this fatigue was simply the violent effort I had made to contract my muscles; still, I point out this observation—which others of the same order appear to confirm—because the correlation between the effort, and the sudden sensation of fatigue is less regular than the connection between that sensation and the phenomenon. Whatever may be the intensity of the effort, the fatigue is felt with less abruptness and in a lesser degree, when the phenomenon is not realised. I may add, that this sensation only appears to me to accompany telekinetic and certain luminous phenomena. It does not, as a rule, accompany raps or automatic manifestations; the fatigue determined by these phenomena makes itself felt progressively and more tardily. I will return to this however. (_d_) The experimenters, and particularly the medium, sometimes speak of a sensation, which they compare to that which is felt, by coming into contact with a spider’s web. This appears to be rarer than the above-mentioned sensations, and, so far, I have not noticed that it was manifested with certain phenomena rather than with others. This sensation of spider’s web is felt about the hands, the face, and at times the back and loins. I cannot give any other indication upon this curious sensation.
