medium exhibits a persistent aversion to the use of recording apparatus: she dislikes smoked paper (for taking impressions of finger prints, etc.); at one'séance it is recorded that she fought hard—and even bit—to prevent the use of a photographic plate.[1] Even more significant is her treatment of two tests recently devised by a circle of Italian medical men. At the first sitting a clockwork cylinder, covered with blackened paper, was placed inside a bell-glass, secured from interference by sealed tapes. The object of the test was to obtain a vertical mark on the cylinder; and the key of the electric circuit through which this end could be accomplished was enclosed in a securely fastened and sealed cardboard box. In the event the sealed tapes were torn off from the bell-glass; the lid of the cardboard box was forcibly removed, and the key then depressed. The test was thus rendered useless. Eusapia explained, however, that if woven material instead of cardboard had been used to protect the key, it could have been moved without interference with the apparatus. Acting on the hint the experimenters prepared for the next'séance a new apparatus. Inside the cabinet was placed a manometer—an open tube of mercury with a floating pointer which would automatically register any movements of the mercury on a scale. The tube was in connection with a vessel full of water, and closed with a rubber capsule. Pressure on the
