Frog. Ad amphibious animal, perfectly harmless, which continues growing for five years, and is very tenacious of life. Frogs are formed from tadpoles; the feet grow, and the tail is absorbed when they leave the ponds, after rain. They subsist on worms and insects; and certain parts of a green frog are eaten in France as a delicacy. Spallanzani kept some torpid in an ice-house for 3 1/2 years, and they revived in the sun.
