Book Of Spells
 

Double, double toil and trouble,
Fire burn and caldron bubble.
Fillet of a fenny snake, In the caldron boil and bake,
Eye of newt and toe of frog,
Wool of bat and tongue of dog,
Adder's fork and bling-worms sting, Lizard's leg and howlet's wing.

For a charm of powerful trouble,
Like a hell-broth boil and bubble.
Double, double toil and trouble,
Fire burn and caldron bubble.
Cool it with a baboon's blood, Then the charm is firm and good
