Round About the Cauldron Go

In honor of the holiday, this passage from Shakespeare's classic play reminiscent of the holiday, Macbeth.
The Scots are all about Halloween.

Round about the cauldron go;   
In the poison’d entrails throw.   
Toad, that under cold stone    
Days and nights hast thirty one   
Swelter’d venom 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 blind-worm’s 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 cauldron bubble.  

Scale of dragon, tooth of wolf,   
Witches’ mummy, maw and gulf  
Of the ravin’d salt-sea shark,  
Root of hemlock 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 ingredients of our cauldron.

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