Thunder. Enter the three Witches.

Thrice the brinded cat hath mewed.

Thrice, and once the hedgepig whined.

Harpier cries. 'Tis time, 'tis time!

Round about the cauldron go;

In the poisoned entrails throw.

Toad, that under cold stone

Days and nights has thirty-one

Sweltered vemon, sleeping got,

Boil thou first i' the charmed pot.

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 blindworm's sting,

Lizard's leg and owlet's wing,

For a charm of powerful trouble,

Like a hell-broth boil and bubble.

Double, double, toil and trouble; Fire burn and cauldron bubble.

Scale of dragon, tooth of wolf,

Witches' mummy, maw and gulf

Of the ravined salt-sea shark,

Root of hemlock digged i' the dark,

Liver of blaspheming Jew,

Gall of goat, and slips of yew

Slivered in the moon's eclipse,

Nose of Turk and Tartar's lips,

Finger of birth -strangled babe

Ditch-delivered by a drab,

Make the gruel thick and slab,

Add there to a tiger's chaudron.

For th' ingredients of our cauldron.

Double, double, toil and trouble; Fire burn, and cauldron bubble.

Cool it with a baboon's blood,

Then the charm is firm and good.
