Abstract

The common grass or leopard frog, Rana pipiens, lives in or near fresh-water lakes, ponds, and streams, and is distributed over the North American continent except on the Pacific slope. The frog has both scientific and commercial value. Frogs legs are highly prized by the epicure. In the laboratory, the frog is used in elementary courses in zoology to illustrate the characteristics of the vertebrates. Holmes very clearly states the present scientific value of the frog, "For a long time the frog has been a favorite object for the study of animal structure and function. Probably no species except man has been the subject of so many investigations. Whenever a physiologist plans to undertake a piece of research his first impulse is to pounce upon the poor frog. A mere list of the articles written about. this well known animal would fill a large volume. Doubtless the fact that frogs are usually easy to obtain is one reason why they have been so extensively studied. Then they are nice clean animals, easy to dissect and admirably adapted for physiological experimentation. The biological sciences owe much to the peculiar virtues of these humble creatures.
