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.
