"Bottazzi himself remarks upon this discrepancy. 'To whom does this hand belong?' he asked--'this hand, a half a yard away from the medium's head, seen while her visible hands are rigorously controlled by her two neighbors? Is it the hand of a monstrous long arm which liberates itself from the medium's body, then dissolves, to afterward "materialize" afresh? Is it something analogous to the pteropod of an amoeba, which projects itself from the body, then retreats into it only to reappear in another place? Mystery!' But this is not the most grewsome sight; one of the professors, stealing a glance behind the medium, saw remnants of legs and arms lying about the cabinet." "Horrible!" exclaimed Mrs. Cameron. "I'd rather believe in spirits. What does he mean to infer?" "Apparently he would have us believe that materialization is a process due to the medium--or at least dependent on her will--and that these partially completed forms represent fragmentary impulses. But I'm not so much concerned just now with that as with the course of schooling through which he drove Eusapia. He stuck to his plan. He put into his cabinet each time certain sounders, markers, and lamps, which could be moved, ticked, or lighted only by hands in the cabinet, and he kept the same rigid control of his medium _outside_ the cabinet. For the most part she was in the light. By means of a series of lamps the seance-room could be lighted dimly or brightly at a touch, and, while many of the phenomena in the cabinet were being performed by 'John,' Eusapia's hands could be plainly seen in the grasp of her inquisitors. After seeing a mandolin move and play of itself, after having the metronome set in motion, stopped, and set going again, after having the registrations he most desired, Bottazzi concludes his third sitting by saying: 'An invisible hand or foot _must_ therefore have forced down the disk, _must_ have leaned on the membrane of the receiving-drum of my apparatus, because I assured myself next day that to obtain the highest lines registered the disk had to be pressed to the extreme point. This was no ordinary case of pushing or pulling. The mysterious hand had to push the disk, and push it in a certain way. _In short, the "spirit hand" was becoming educated to its task._'" Miller asked: "Did these performances take place, as in the case of Mrs. Smiley, within the reach of her ordinary limbs?"
