Shakespeare's Website

    Double, double, toil and trouble; fire burn, and cauldron bubble. Fillet of a fenny snake, in the cauldron boil and bake; eye of newt and toe of frog, wool of bat, and tongue of dog, adder's fork, and blind-worm's sting, lizard's leg and howlet's wing, for a charm of powerful trouble, like a hell-broth boil and bubble.
