“… with my patient M.M., I could at any time produce muscular contraction, showing itself in well-marked spasm, simply by pointing my finger at her, from a distance of ten or twelve feet, and this occurred whether she was aware of my action or not, or even of my presence, and the same effect was produced through a closed door. On one occasion I made a visit at an altogether unusual hour and asked an attendant, who was also interested in the experiment, to be in the room with the door just sufficiently ajar, so that my movements could be observed by her while standing near the very slight opening. The patient was lying on the bed at least ten feet from the door with her back toward it and quite unaware of my presence, but the moment I pointed energetically toward her through the door, the same convulsive action occurred and was repeatedly observed by the attendant.”
