The Quack Frog
A Frog emerging from the mud of a swamp, proclaimed to all the world that he was come to cure all diseases. "Here!" he cried, "come and see a doctor, the proprietor of medicines such as man never heard of before; no, not /Esculapius himself, Jove's court-physician!" "And how," said the Fox, "dare you set up to heal others, who are not able to cure your own limping gait, and blotched and wrinkled skin?" Test a man's professions by his practice.
