Of more recent experiments with diagrams, those recorded by Herr Anton Schmoll and M. Etienne Mabire are perhaps the most important.[23] The experiments took place at Herr Schmoll's house, 111 Avenue de Villiers, Paris. In addition to Herr Schmoll and M. Mabire, Frau Schmoll and four or five other persons assisted at one time or another. Mr. F. W. H. Myers was also present on three occasions. In all about 100 trials were made with diagrams and real objects (the actual number of experiments of all kinds was 148), full details of which will be found in the original papers. The experiments were made in the evenings, in a room lighted by a hanging lamp. The agents, usually three or four in number, sat at a round table immediately under the lamp, and fixed their eyes on the diagram or object, which was placed on the table before them. The percipient, with his eyes bandaged, sat in full view of the agents with his back to them in a corner of the room at a distance of about ten feet from the object. Silence was maintained during the experiments, except where otherwise expressly stated. The object or diagram was carefully hidden before the handkerchief was removed from the eyes of the percipient to enable him to draw his impression. In the first nineteen experiments the figure was drawn with the end of a match dipped in ink, whilst the percipient was in the room. It was not likely, under the circumstances, as the match moved almost noiselessly over the paper, that any indication of the figure drawn could by this means have been given to the percipient. Nevertheless, in the later experiments quoted the precaution was taken to draw the figure whilst the percipient was in another room, and a soft brush was substituted for the match. The following is a record, by Herr Schmoll, of the last two evenings of the first series:-- 18.--_August 24th, 1886._ _Agents_--Mdlle. Louise, Frau Schmoll, Schmoll. _Percipient_--M. Mabire. _Object_ (drawn)-- [Illustration] _Result_--M. Mabire saw "a sort of semicircle like the tail of a comet, but of spiral construction, like some of the nebulæ." What he saw he reproduced in the following manner:-- [Illustration] 19.--_The same evening._ _Agents_--Mdlle. Louise, M. Mabire, Frau Schmoll. _Percipient_--Schmoll. _Object_ (drawn)-- [Illustration] _Result_--"I see two double lines, that cross each other at about right angles." (Pause.) "The two double lines now appear single, but like rays of light, and in the form of an =X=." (Another pause.) "Now I see the upper part of the =X= separated from the lower by a vertical line." I draw:-- [Illustration] 20.--_The same evening._ _Agents_--Mdlle. Louise, M. Mabire, Schmoll. _Percipient_--Frau Schmoll. _Object_--A brass weight of 500 grms. was placed on the table. [Illustration]
