"Double, double, toil and trouble;
Fire burn and cauldron bubble.
Cool it with a baboon's blood,
Then the charm is firm and good.

O well done! I commend your pains;
And every one shall share in the gains;
And now about the cauldron sing,
Live elves and fairies in a ring,
Enchanting all that you put in.

By the pricking of my thumbs,
Something wicked this way comes."

Wm. Shakespeare, Macbeth,
