The vapors are condensedor adsorbed on the charged or uncharged oxidationproducts of phosphorus (If^Oe and P2O5). If thevapors react with phosphorus trioxide they increasethe rate of oxidation. If they are inert, theyprevent further oxidation of phosphorus trioxideand also form a cloud near the surface of thephosphorus. This cloud approaches nearer andnearer the surface as the oxidation becomes lessenergetic and in certain cases may form a pro-tecting film that stops the oxidation entirely.

The recent remarkable developments of physical theories, especially thoseconcerned with relativity and quanta of energy, cannot fail to have far-reachinginfluences on philosophical thought. Professor Rougiers very wide reading inmathematical and experimental physics has enabled him to present and interpretthe new advances in physics in a way which should prove of great interest toboth philosopher and physicist. The book marks a measurable advan
