Feathers and Scales.

“I with my long nails will dig thee pig-nuts;
Show thee a jay’s nest, and instruct thee how
To snare the nimble marmoset.”
The Tempest – Act II, 2

"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."

Macbeth- Act IV,1
