INTERIOR VISION. 39 fectly scientific, the whole thing being of a magnetic nature, — clairvoyance under unusual conditions, and easily formulated exactly, as will be done before I finish this monograph. I quote: — Frederick, the Great, was thus forced to resume his’ philosophical serenity without assistance. He said, ‘Since we are talking’ of Cagliostro, and the hour for ghosts and stories has come, I will tell you one which will show how hard it is to have faith in sorcerers. My story is true; for I have it from the person to whom it happened last year.” ‘Ts the story terrible?” asked La Mettrie. ‘* Perhaps,” said Frederick. “Then I will shut the door; for I cannot listen with a door gaping.” La Mettrie shut the door, and the king spoke as follows: — “ Cagliostro, as you know, had the trick of showing people pictures, or rather magic mirrors, on which he caused the absent to appear. He pretended to be able to reveal the most secret occupations of their lives in this manner.

She is well educated, thinks well about all matters, and I have reason to know no narrow or restricted idea makes any impression upon her. “ She remained in the ghost-room long enough to make her companions very uneasy.
