"I call 'Ready?' The percipient says, 'Yes.' We have been drawing at the same time in different rooms. On returning to the study I compare the drawings and see with astonishment that Fräulein A. has drawn a serpent. Even the open mouth and the thickened end of the tail in the reproduction agree with the original. The experiment has succeeded in its essential part, and as regards strictness of conditions I think it quite unassailable. Unconscious suggestion is absolutely excluded, when agent and percipient are in different rooms. Any corresponding association of ideas seems to me also impossible, for the idea of the staff of Æsculapius first occurred to me in the other room. In the study there is no object which could have led up to the idea--no indication which could have pointed out the way." The percipient had, in fact, drawn a spiral figure apparently intended to represent a serpent. The two other experiments here referred to were performed in immediate succession, and under precisely similar conditions, the time allowed in each case being about two minutes. In the second experiment the agent drew an arrow; the percipient drew another spiral, with intersecting loops. In this case, as the agent points out, the original idea of the serpent appears to have persisted in the percipient's mind. In the third experiment the agent drew a triangle inscribed in a circle; also two diameters to the circle, crossing each other at right angles, the vertical diameter bisecting the upper angle of the triangle. The agent writes:-- "The drawing was done in the following way. I began with the triangle, and then drew the perpendicular on the base. The idea that thereupon occurred to me, that the figure was too simple, induced me to add a circle and to prolong the perpendicular to the circumference; finally I added the horizontal diameter. The percipient was drawing at the same time at table _b_, sitting on chair 5, with her back to the closed door of communication. Question from the next room, 'Are you ready?' Answer, 'Stop,' as I am about to open the door. Then, 'Now.' I open the door and enter the room. The two drawings agree except that the circle and the horizontal diameter are wanting. Even the perpendicular of the triangle, which has become obtuse angled, is prolonged beyond the base, just as in the original. This prolongation and addition of the perpendicular cannot be explained by any tendency of ideas to recur (diagram-habit). Only the fact that a triangle was drawn might, taken alone, be explained in some such way." Figures of the original diagrams in this case are given in the _Proceedings of the S.P.R._
