Ere to guide others we pretend.
A sallow, wrinkl'd, spotted Frog,
To turn physician left the bog.
"He every malady could cure,"
He said, "that animals endure." —
"First on yourself your science shew,"
Says Reynard: "That the world may know
Your skill and knowledge, pray begin
Of those foul spots to clear your skin;
For while you look so sick and pale,
To vend your drugs you'll ne'er prevail."
