Life: A Book for Elementary Students (Classic Reprint)Excerpt from Life: A Book for Elementary Students Living matter or, as Huxley phrased it, the physical basis of life, is a substance called by Hugo von Mohl protoplasm. Since this protoplasm is always being added to from the outside world in the form Of food and oxygen, and per contra is always giving up something to the outside world in the form Of carbon dioxide breathed out and of other excreta, some might regard it more in the light of a Space, in which various elements enter, combine, disintegrate and take their exit, than as a substance. Still, for the convenience of this book we will regard it as a substance never constant in composition for a single second.
