"MR. FURNESS. Under what conditions can you influence them? "The response, which was partly inaudible at the reporter's seat, was understood to be: 'I cannot tell.' "MR. FURNESS. You say that in the generality of cases they are beyond your control? "The 'MEDIUM.' Yes. "MR. FURNESS. How in the world shall we test that? "The 'MEDIUM.' Well, by-- "MR. FURNESS. By--what? Isolating you from the table? "The 'MEDIUM.' Yes. "MR. FURNESS (applying his right hand, by her permission, to the 'Medium's' head). Are you ever conscious of any vibration in your bones? "The 'MEDIUM.' No; but sometimes it causes an exhaustion, that is, under circumstances when the raps do not come freely. "MR. FURNESS. The freer the raps come, the better for you? "The 'MEDIUM.' Yes, the freer the better--the less exhaustion. "MR. SELLERS. But do you feel now, to-night, any untoward influence operating against you? "The 'MEDIUM.' No, not to-night, for it takes quite a little while before we feel these things. "MR. FURNESS. Do these raps always have that vibratory sound--tr-rut--tr-rut--tr-rut? "The 'MEDIUM.' Sometimes they vary. "MR. FURNESS. As a general rule I have heard them sound so. "The 'MEDIUM.' Every rap has a different sound. For instance, when the 'spirit' of Mr. Seybert rapped, if the sound was a good one, you would have noticed that his rap was different from that of another. Every one is entirely different from another. "MR. FURNESS. Do you suppose that the present conditions are such that you can throw the raps to a part of the room other than that in which you are? "The 'MEDIUM.' I do not pretend to do that, but I will try to do it. "Mr. Furness and Dr. Leidy station themselves in the corner of the room, diagonally, and most remote from the pine table, at which their associates remain seated, with their hands upon the table, and 'their minds intent on having the raps produced at the corner indicated,' as requested by the 'medium,' who also remains at the table. The 'medium' asks, '_Will the "Spirit" rap at the other side of the room?_' and, after twelve seconds, and again after forty-three seconds, repeats the inquiry. _No response is received._ The experiment is repeated with Mr. Furness and Dr. Koenig at the corner, but with a like negative result." Let us now turn to the experiments made while the "medium" was not in a position in which her feet could touch the floor. The report says: "Mr. Sellers made this inquiry: "'It is proposed that the "medium" shall stand upon tumblers. Are we likely to have any demonstration?' "Three raps--promptly given, though feeble in delivery and but faintly audible. "The 'MEDIUM.' There were three--a kind of tardy assent. "MR. SELLERS (to the 'Medium'). As if the 'Spirits' might or might not communicate? "The 'MEDIUM.' Well, that a trial might be made. "Three raps are here again distinctly heard--the characteristics of the sounds in this instance being rapidity and energy, or positiveness.
