“The excellent conditions of light under which the experiment took place, the control of sight and touch which I most carefully exercised, the proximity of the statuette to my eyes, all this renders the absence of any hair or thread most certain for me. This is the second time I have heard this scraping sound. “M. Meurice was extremely fatigued after the production of this phenomenon, and fainted. On recovering himself, he insisted on trying once more, and succeeded in making the statuette sway about. “The day following this experience, he attracted several small articles—wine-glasses, bread, etc.—near his reach on the luncheon-table. I was not present, however. “You perceive how very suspicious the phenomena sometimes _appear_ to be. Nothing short of actual observation could demonstrate the absence of a connecting link of some kind between the medium’s hands and the object in movement.” C. LUMINOUS PHENOMENA _By Dr. X._ “For about eighteen months, Dr. Maxwell has been endeavouring to turn the phenomena in the direction of luminosities or materialisations. “With that object in view, he has had a light portable cabinet constructed. This fragile apparatus consists of eight pieces of pinewood fitting into one another by means of hooks. When put together, there is just enough space inside the cabinet to allow of the introduction of a small, straight-backed chair; a person sitting thereon, finds himself in contact with the back and sides of the cabinet, and his knees against the door. A large curtain of purple cloth has been made, which is thrown over the cabinet, covering it completely. The curtain is buttoned over the door. “The luminous phenomena already obtained with this medium and spoken of by Dr. Maxwell on pages 152-5, were sufficient grounds for hoping that patience and perseverance might, finally, obtain happy results capable of being repeated. “For more than a year nothing demonstratively objective was forthcoming. In the darkness, one often imagined one could see clouds of vapour moving about near the cabinet; but there was nothing to prove that this appearance was anything more than an optical illusion. On these occasions, the medium frequently complained of a disagreeable sensation on his hands and face, as though he were caught in a spider’s web. He has also said, that he perceived from time to time an odour of phosphorus or ozone in the cabinet; the medium has been the only one of the experimenters to notice this odour, so far. “Whenever I have been present at these attempts, I have observed that they were accompanied by complete cessation of all other phenomena, such as visions, raps, telekinesis. Until November 1904, this apparently negative result was about all that was obtained at these dark seances. “During the first week in November, the medium being in good form, and the ‘force’ abundant, it was decided to devote a few days, which Professor Richet was able to dispose of, to an effort to obtain luminous phenomena.
