Vance Barnum, Joe Strong, the boy wizard; or… (1916)
“ Just here it may be stated for the benefit of readers unacquainted with the prestidigitator’s art, that “palming,” as it is known in the profession, is the act of holding an egg, billiard ball, lemon, coin, or some similar object, in the palm of the hand, by a slight contraction of the ball of the thumb, in such a manner that the hand, when the back of it is held out in front of an audience, appears perfectly empty. Passing of articles from one hand to another, involves palming, as does causing to “disappear” certain articles apparently taken from a person’s hat, clothes and so on. ”
