Behind the curtain, upon the plinth of the projection of a bookcase and upon a table, we placed a guitar, also a violin, a tambourine, an accordion, a music-box, cushions, and several small objects, which were to be shaken, seized, thrown about by the unknown force. The first result of these seances in Paris, at my house, was absolutely to establish the fact that the hypothesis of a confederate is inadmissible and ought to be entirely eliminated. Eusapia acts alone. The fifth seance led me, moreover, to think that the phenomena take place (at least a certain number) when the hands of Eusapia are closely held by two controllers, that it is not generally with her hands that she acts, in spite of certain possible trickeries; for it would be necessary to admit (an abominable heresy!) that a third hand could be formed in organic connection with her body! Before every seance Eusapia was undressed and dressed again in the presence of two ladies charged with seeing that she did not hide any tricking apparatus under her clothes. It would be a little long to go thoroughly into the details of these eight sittings, and it would be partly to go over what has already been described and commented upon in the first chapter, as well as in the preceding pages. But it will not be uninteresting to give here the estimate of several of the sitters, by reproducing some of the reports. I will begin with that of M. Arthur Levy, because he describes very fully the installation, the impression produced upon him by a medium, and the greater part of the facts observed. Report of M. Arthur Levy (_Seance of November 16_) That which I am going to relate I saw yesterday at your house. I saw it with distrust, closely observing all that might have resembled trickery; and, after I had seen it, I found it so far beyond the things that we are accustomed to conceive that I still ask myself if I really saw it. Yet I must confess that I have not been dreaming. When I arrived at your salon, I found the furniture and all the other arrangements as usual. On entering, only a single change could be remarked at the left, where two thick curtains of gray and green rep concealed a little corner. Eusapia was to perform her wonders before this kind of alcove. This was the mysterious corner: I examined it very minutely. It had in it a little round uncovered table, a tambourine, a violin, an accordion, castanets, and one or two cushions. After this precautionary visit, I was certain that in this place at least there was no preparation, and that no communication with the outside was possible. I hasten to say that from this moment up to the end of the experiments we did not leave the room for a single minute, and that, so to speak, we had our eyes constantly fixed upon this corner, the curtains of which, however, were always partly open.
