Round about the caldron go; In the poison’d entrails throw. Toad, that under cold stone, Days and nights has thirty-one; Swelter’d venom sleeping got, Boil thou first i’ the charmed pot! — First Witch, “Macbeth,” IV:1

Double, double toil and trouble; Fire burn, and caldron bubble. — Witches, “Macbeth,” IV:1

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 howler’s wing, for a charm of pow’rful trouble, like a hell-broth boil and bubble. — Second Witch, “Macbeth,” IV:1

Double, double toil and trouble; Fire burn, and caldron bubble. — Witches, “Macbeth,” IV:1

Scale of dragon; tooth of wolf; Witches’ mummy; maw and gulf Of the ravin’d salt-sea shark; Root of emlock digg’d i’ the dark; Liver of blaspheming Jew; Gall of goat, and slips of yew Sliver’d in the moon’s eclipse; Nose of Turk, and Tartar’s lips; Finger of birth-strangled babe Ditch-deliver’d by a drab, Make the gruel thick and slab: Add thereto a tiger’s chaudron, For the ingrediants of our caldron. — Third Witch, “Macbeth,” IV:1

Double, double toil and trouble; Fire burn, and caldron bubble. — Witches, “Macbeth,” IV:1

Cool it with a baboon’s blood, Then the charm is firm and good. — Second Witch, “Macbeth,” IV:1
