“I command you to dip your two front feet into this magic compound and then fly away until you meet a child. Fly close, whether it be a boy or a girl, and touch the child upon its forehead with your feet. Whosoever is thus touched, the book declares, will at once become a pig, and will remain such forever after. Then return to me and dip your legs afresh in the contents of this cup. So shall all my enemies, the children, become miserable swine, while no one will think of accusing me of the sorcery.”
