Three Hundred Æsop's Fables/The Goat and the Ass
A man once kept a Goat and an Ass. The Goat, envying the Ass on account of his greater abundance of food, said, "How shamefully you are treated: at one time grinding in the mill, and at another carrying heavy burdens"; and he further advised him to pretend to be epileptic and fall into a ditch and so obtain rest. The Ass listened to his words, and falling into a ditch, was very much bruised. His master, sending for a leech, asked his advice. He bade him pour upon the wounds the lungs of a Goat. They at once killed the Goat, and so healed the Ass.
