The Fiery Flash.

To split a piece of money into two parts.
Fix three pins in the table, and lay the piece of money upon them; then place a heap of the flowers of sulphur below the piece of money, and another above it, and set fire to them. When the flame is extinct, you will find on the upper part of the piece a thin plate of metal, which has been detached from it.

A very easy method of gilding ivory.

How to make the Constable catch the Knave.
Take a pack of cards and look out the four knaves, lay one of them privately on the top of the pack, and the other three on the table, saying, here you see, are three knaves got together, about no good you may be sure, then lay down a king by the side of them saying, but here comes the constable and catches them together. Oh, oh, says he, have I caught you then together? Well the next time I catch you together I’ll punish you severely for your rogueries. Oh, but, says they, you shan’t catch us together in haste; so they determine to go three different ways. I’ll go here, says one, (so take one of the knaves and put him at the top of the cards.) I’ll go here, says another, (so put him at the bottom.) And I’ll go here, says a third, (so put him exactly in the middle.) “Nay,” says the constable, “if you run I’ll make sure of one, so I’ll follow the first, then take the king and put him at the top of the pack, and let any one cut the cards three or four times, and then deal; cut the cards one by one, and you will find three together, and the constable with them.”
