From Egyptian Secrets of Albertus Magnus, Joseph H. Peterson edition:
How to Shoot Securely.
Take the heart of a bat, and the liver at that, and mix it with the lead when thou doth bullets cast, and thou will shoot all things dead. Take a skull, and place the die under it, pour the lead through the eye-holes into the mould, and with such bullets and balls shoot. Probatum!
