I remember a series of fraudulent experiments, in the course of which several touches were given. The first touches, through the curtains, made me think of the contacts obtained with Eusapia; but obscurity reigned complete, and I have reason to believe that the medium’s left-hand neighbour touched me with a stick. I was also touched on the knee, but it was by a very natural hand, which belonged to one of the experimenters, a man of inferior intellect. Inexperienced people are easily deceived by these contacts; however, the marked difference which exists between the falsidical and the veridical is quickly perceived, when we have become accustomed to these phenomena. I do not advise experimenters to put themselves under the conditions in which these facts are observed, as they are very unfavourable for the examination of the phenomenon. These conditions, as far as I have been able to judge, are:—(1) the formation of a chain around a table, the medium being seated with his back to the curtains of the cabinet; (2) an extremely feeble light, or none at all. It is only with Eusapia that I have obtained touches with light, and even then the light was of the weakest. These touches, besides having the inconvenience of carrying little conviction with them, because of the conditions under which they are obtained, have also the disadvantage of impressioning persons who are easily moved and frightened. I have seen very courageous people affected by these touches. Therefore we must not try to obtain them, until we are already familiarised with the observation of physical phenomena. It is to be noted, that the phenomenon of _attouchement_ presents the characteristics pointed out in those I have already examined. In the first place, we note the correlation which exists between the movements of the medium and the contact. I gave an example just now, when relating the phenomena of which General Thomassin was the object. The movements of the right hand which touched him were mimicked by Eusapia’s right hand, which was visible, held by M. de Gramont, and seen by every one. Here is another example, taken from my notes, in which synchronous movements were executed by one of the experimenters:—
