Scale of dragon, tooth of wolf,
Witch's mummy, maw and gulf
Of the ravined salt-sea shark,
Root of hemlock digged i' th' 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' ingredience of our cauldron.
— William Shakespeare
