It is sometimes required of the performer to show that his hands do not contain any coin. If a coin is palmed in one of them, he must first exhibit the other open in a very ostentatious manner, and, whilst the audience is momentarily engaged in looking at it, press the coin, by means of the thumb, through the fingers of the hand in which it is held, so that it protrudes at the back, and cannot be seen from the front (Fig. 6). Some performers have brought this palm to a great state of perfection. One very telling effect is to pretend to throw the coin away. For this purpose, it is held between the tips of the first finger and thumb, whilst lying upon the side of the middle finger. As the action of throwing is imitated, the forefinger is slid over the coin, the thumb being removed, and the coin thus made to protrude at the back of the hand.
Other fanciful methods of palming exist, but they will be of no practical use to the conjuror, so I have omitted descriptions of them.
