_Forms and Phantoms._--At Bordeaux, in 1897, the room where we held our sittings was lighted by a very large window. The outside Venetian blinds of this window were closed; but when the gas was lighted in a little building which formed an adjunct to the kitchen, in the corner of the court near the garden, a feeble light penetrated the room and dimly illuminated the window panes. The window itself formed in this way a bright background upon which certain dark forms were perceived by a part of the experimenters. We all saw these forms, or rather this form, for it was always the same one that appeared,--a long bearded profile, with a very high arched nose. This apparition said it was head of John, a personification who always appears with Eusapia.[72] This is a very extraordinary phenomenon. The first idea which presents itself to the mind is that this is a case of collective hallucination. But the care with which we observed this curious phenomenon--and, it seems needless for me to add, the calmness with which we experimented--renders this hypothesis very unlikely. The supposition of fraud is still less admissible. The head, which we saw was of life size, measuring say sixteen inches from the forehead to the end of the beard. It is impossible to understand how Eusapia could have hidden in her pockets or under her clothes any kind of a cardboard profile. Nor can one understand any better how, unknown to us, she could have taken out this paper figure, mounted it upon a stick, or upon a wire, and so operated with it. Eusapia had not gone into a trance: she herself sometimes saw the profile which appeared, and, thoroughly awake and conscious, took pleasure in assisting in the phenomena which she was producing. The feeble light which the illumined window shed was sufficient to enable us to see her hands being carefully held by the controllers on the right and on the left. It would have been impossible for her to manipulate these objects. In fact, however, the profile observed seemed to form at the top of the cabinet, at the height of about three and a half feet above Eusapia's head. It descended rather slowly and so took its place above and in front of her. Then at the end of some seconds it disappeared, only to reappear some time afterwards in the same circumstances. Every time, we carefully assured ourselves of the relative immobility of the hand and arms of the medium. Hence I regard the prodigy which I am relating as one of the most certain I ever verified, so incompatible was the hypothesis of fraud with the conditions under which we observed. I am persuaded that these facts will one day (soon perhaps) receive the stamp of scientific approval as subjects of study. They will do this in spite of the obstacles which obstinate infatuation and the fear of ridicule pile in the way.
