Pass the marked coin off the stage to your confederate, who puts it down the tube into the ball of cotton, and leaves it there in the centre; on withdrawing the tube the hole can be completely covered up by pressing the cord around it.
Thus prepared, the ball is brought to you in a glass cup, having a hole in the rim through which you pass one end of the cotton. Fasten this to a winding-off wheel (broad-tired), and as your assistant winds off the cord, you pretend to throw the coin into the ball. Immediately, the marked piece falls into the bottom of the vessel, in which it is taken to the owner.

THE OBEDIENT SIXPENCE.
Fig. 12.
Lay a sixpence between two shillings on a table-cloth, and cover them with a tumbler, and offer to remove the middle one without touching the others or the glass. To do so scratch the cloth with the finger-nail, and the lesser coin will move out towards you, the others being held by the tumbler.
