The Witches Caldron
　by William Shakespeare

　"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 owlet's wing"

　"For a charm of powerful trouble,
　Like a hell-broth boil and babble"

　"Double, double, toil and trouble,
　Fire burn, and caldron bubble"
