The best formula for successfully using flat base is the following:
Add four parts Flat Base and
Round about the Cauldron go;
In the poison'd Entrails throw.
Toad, that under cold stone
Days and Nights has thirty-one
Swelter'd Venom sleeping got,
Boil thou first i' the charmed pot.
Double, double toile and trouble ;
Fire burn and Cauldron bubble.
Fillet of a Fenny Snake,
In the Cauldron boil and bake;
Eye of Newt, and Toe of Frogge,
Wool of Bat, and Tongue of Dogge,
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 toyle 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
Silver'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.
Cool it with a Baboon's blood,
Then the Charm is firm and good.
O! well done! I commend your pains,
And every one shall share i' the gains.
And now about the Cauldron sing,
Like Elves and Fairies in a Ring,
Enchanting all that you put in.
Black spirits and white, red spirits and gray;
Mingle, mingle, mingle, you that mingle may.
