The first trick that e’er learn’d to do,
Was, out of one ball to make it into two:
Ah! since it cannot better be,
One of these two, I’ll divide them into three,
Which is call’d the first trick of dexterity.
So then you have three balls on the table to play with, and one left between the fingers of your right hand.
The Operation of the Cups is thus.
Lay your three balls on the table, then say, Gentlemen, you see here are three balls, and here are three cups, that is, a cup for each ball, and a ball for each cup. Then, taking that ball that you had in your right hand, (which you are always to keep private) and clapping it under the first cup, then taking up one of the three balls, with your right hand, seeming to put it into your left hand, but retain it still in your right, shutting your left hand in due time, then say, Presto, be gone.
