This volume is a résumé of the work done by these two capable scientists during the last ten years not only in developing their concept of the physical state of matter (protoplasm) but also in studying the physical and chemical laws which make this concept probable. By studying the physical and physicochemical properties of such colloidal systems as phenol/water, quinoline/water and casein/water (to mention a few), they arrived at the conclusion that protoplasm itself is not a solution of protein and minerals in water, but that it is actually one of the inverse type. In other words, instead of being a dilute solution of "x" in water, it is a concentrated solution of water in "x," and as such cannot possibly fit into the schemata proposed by the "dilute solution" chemists. As a corollary to the axiom may be mentioned new and extremely interesting information regarding the disenfranchisement of the
