Professor Hoffmann,
Latest Magic, Being original conjuring tricks
“ But this is where magic comes in. What I really did was to hypnotise you a little so as to make you fancy, when I told the cards to change, that the eight of hearts was the seven of spades, and that the seven of spades was the eight of hearts. It’s quite simple, when you know it, and you can see for yourselves that the quickness of the hand has had nothing to do with the matter. For my own part I like to do things slowly; the more slowly the better, and then you can all see how it’s done.”The trick is simple enough; but it will test the performer’s expertness as to neatness of execution. ”
