"We had one very successful experiment with a young girl of about fifteen, Mdlle. Camille Simon, in the presence of M. Brullard and several other persons. I gave her a mental suggestion that on waking she should see her hat, which was brown, changed to yellow. I then put her _en rapport_ with all the others, and I passed round a slip of paper indicating my suggestion, and asking them to think of the same thing. But, by a lapse of memory not unusual to me, I did not think after all of the colour which I had written down; I had a distinct impression that she would see her hat _red_. On awaking her I told her she would see something representing our common thought. When she was wakened she wondered at the colour of her hat. 'It was brown,' she said. After having thought for a long time, she assured us that really it did not look at all the same, that she could not quite define the colour, but that it seemed to her a sort of yellow-red. Then I remembered my aberration. In the present case the others thought of yellow, I of red: thus the object appeared yellow and red to the awakened somnambule; which proves that the mental suggestion may be the echo of the thought of many minds." [The following experiment, made with the same "subject," and sent to us by Dr. Liébeault on June 3, 1886, is an interesting example of temporary latency of the telepathic impression:--] "In another experiment with the same young girl it was suggested to her, mentally, by several persons that on awaking she would see a black cock walking about the room. For a considerable time after waking, nearly half-an-hour, she said nothing, although I told her she would see something. It was about half-an-hour afterwards that, having gone into the garden and looked by chance into my little courtyard, she came running back to us to say, 'Ah, I know what I was to see: it was a black cock. This came into my head when I was looking at your cock.' My cock is greenish-black on the wings, tail and breast; everywhere else he is yellowish-white. Here we have an idea caused by the sight of a real object associated with a fictitious idea mentally transmitted by the persons present."
