"Well, do you think I have nothing else to do! Why do you call me? I have had to leave everything." "We wanted to say 'good morning' to you." "Very well! I am going away now." She shook hands with us and went away quickly; whereupon it occurred to me to make her stop just at the gate. (Mental command)--"I forbid you to go out. You cannot open the gate; come back." And back she came, furious, asking if we were laughing at her. Now, to send this last command I had not moved at all from my place, and M. was completely invisible behind the garden wall; moreover, I was a long way from the window. I told her that this time she could open it, and let her go. I will finish with another experiment of the same kind, which only partly succeeded, but which will serve to show the intensity of the mental transmission between M. and me. I went away, one morning, without thinking of M. I had to be away all day, 38 kilomètres from her. At 2.30 it occurred to me to send her a mental command, and I repeated it for ten minutes. "Go at once to the dining-room; you will take a book there that is on the mantelpiece; you will take it up to my study, and you will sit in my armchair before my writing-table." I reached home at night. The next day, as soon as I saw M., and even before saying good morning to me, she cried: "I did a clever thing yesterday. I must be losing my wits, I suppose! Just imagine! I came down without knowing why, opened the dining-room door, then went up to your study, and sat in your armchair. I moved your papers about, then I went back to my work." The command had then been understood; but she did not go into the dining-room, and she did not take the book from there. J. H. P. (_Annales des Sci.

The following is a record of a series of trials in the transference of auditory impressions: No. 33.--From MISS X.
