(_a_) The sensation of cool breezes, generally over the hands. (_b_) The sensation of a slight tingling in the palm of the hand, and at the tips of the fingers, near the mounts. (_c_) The sensation of a sort of current through the body. (_d_) The sensation of a spider’s web in contact with the hands and face, and other parts of the body—notably the back and loins. (_e_) The sensation of fatigue after strong phenomena. (_a_) The first is very frequently mentioned by experimenters. It is an impression of coolness, or even of cold, which they generally feel over the hands. I have not been able to settle with certitude, if this sensation be purely subjective, or if an element of real objectivity be blended with it. It is at times so marked, that I have some difficulty in believing that it is altogether imaginary. Though it often precedes the production of a motor phenomenon, it more frequently happens, that the sitters feel it without any paranormal fact being forthcoming. This peculiar sensation is similar to what is felt in seances with Eusapia Paladino, when approaching one’s hand to the scar on her head. What she calls the _soffio freddo_ is very decidedly felt: it is as though a current of air were escaping through the scar. The reality of this sensation with the Neapolitan medium makes me think, that the cool breeze mentioned in other seances may have some objectivity. It is to be noted, that I have observed this phenomenon with mediums, who had no familiarity whatever with spiritistic seances. Sometimes, the sensation of coolness or of cold extends to the whole body. Mediums are more likely to feel this than other experimenters. This sensation can bring on veritable shivering, in which case it often coincides with a phenomenon. (_b_) A tingling sensation may seem to be solely due to immobility, or to other ordinary causes, such as prolonged contact of the fingers with the table. I recognise that this explanation is true nine times out of ten; but in certain cases it has appeared insufficient to me: either it was felt too soon after the debut of the sitting to be due to fatigue, immobility, or to prolonged contact, or its coincidence with certain well-observed phenomena was too frequent to be fortuitous. Therefore it appears to me probable, that there is some connection between this tingling sensation and the emission of the force utilised.
