"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 pow'rful trouble,
Like a hell-broth boil and bubble."
-- Second Witch, "Macbeth," IV: 1 by William Shakespeare
