DUAL CONSCIOUSNESS. 283 



the subject, though nothing was said, nor could the subject 

 have seen what had occurred to the operator. To be 

 assured of this he bandaged the girl's eyes with great c.re, 

 and the operator having gone behind the girl to the other 

 end of the room, he watched him and the girl, and repeat- 

 edly assured himself of this fact' Thus far, Professor 

 Barrett's observations, depending in part on what the 

 operator experienced, may be open to just so much doubt 

 as may affect our opinion of the veracity of a person un- 

 known ; but in what follows we have his own experience 

 alone to consider. ' Having mesmerised the girl himself, 

 he took a card at random from a pack which was in a 

 drawer in another room. Glancing at the card to see what 

 it was, he placed it within a book, and in that state brought 

 it to the girl. Giving her the closed book, he asked her to 

 tell him what he had put within its leaves. She held the book 

 close to the side of her head, and said, ' I see something 

 inside with red spots on it ; and she afterwards said there 

 were five reel spots on it. The card was the five of 

 diamonds. The same result occurred with another card; 

 and when an Irish bank-note was substituted for the card, 

 she said, * Oh, now I see a number of heads so many that 

 I cannot count them.' He found that she sometimes failed 

 to guess correctly, asserting that the things were dim ; and she 

 could give no information of what was within the book un- 

 less he had previously known what it was himself. More 

 remarkable still, he asked her to go in imagination to 

 Regent Street, in London, and tell him what shops she had 

 seen. The girl had never been out of her remote village, 

 but she correctly described to him Mr. Ladd's shop, of 

 which he happened to be thinking, and mentioned the large 

 cloc ; that overhangs the entrance to Beak Street. In many 

 other cases he convinced himself that the existence of a 

 distinct idea in his own mind gave rise to an image of the 

 idea (that is, to a corresponding image) on the mind of the 

 subject; not always a clear image, but one that could not 

 fail to be recognised as a more or less distorted reflection of
