"He does not say in this case, but, as I recall it, they found in other instances that the lines on the impressions made by Eusapia's invisible fingers were precisely like those of her material fingers, and yet no mark of flour or lamp-black remained attaching to her hands. In one case a perfumed clay was used, and, although the impressions secured 'resembled Eusapia's face grown old,' no scent of the wax could be detected on her cheeks. Bottazzi gives much space to these 'mediumistic explorations of the cabinet.' He could follow these blind, mysterious gropings of the invisible Eusapia by closely controlling the real Eusapia. 'Presently she asked: "What is that round object? I feel something round."' This was, in fact, the rubber ball which connected with a tube--the tube, in its turn, passing through the wall into another room where it operated a manometer. She pressed this ball with her invisible limbs, and the column rose and registered the pressure. This was entirely satisfactory to Bottazzi, who then says: 'I desire again to affirm that with her invisible limbs Eusapia feels the forms of objects and their consistency, feels heat and cold, hardness and softness, dampness and dryness neither more nor less than if she were touching and feeling with the hands imprisoned in ours. She feels with other hands, but perceives with the same brain with which she uses to talk with us.' "The most astonishing physical phenomena came when the contact-breaker was thrown on the table, and Eusapia called out: 'See how it moves!' '_We all directed our gaze toward the small object_,' says Bottazzi, '_and we saw that it oscillated and vibrated at an elevation of an inch or two above the surface of the table, as if seized with internal shivering--Eusapia's hands, held by M. Galeotti and myself, being more than a foot from the contact-breaker_.'" My auditors were now in the thrall of Bottazzi's story, and the silence was eloquent. At last Cameron said: "It certainly seems like a clear case of 'astral.' I begin to believe in our first sitting with Mrs. Smiley. What do you want us to do--announce ourselves converted?"
