Written for the Popular Science Library edited by Garrett P. Serviss, this survey begins with the signs of life and the ways an organism maintains itself. It moves through food and its uses, cells, the skeleton, muscles, blood and its clotting, breathing, circulation and the nervous system, in plain language for the general reader.
