Abstract

THE theory of atomic structure has, during the past few years, reached a stage of sufficient success and stability for it to be possible to describe many of its features in a simple manner. There is a general agreement as to the validity of certain fundamental conceptions, such as the nuclear structure, the interpretation of isotopes, and the general functions of the outer electrons, while, to turn to more delicate points, the quantum theory and the wave theory of radiation, like an ill-assorted couple of individually worthy people, have learnt to live together in peace by a tacit agreement not to insist too much on each other's faults, so that it is possible for their friends to ignore their essential incompatibility. In short, the times seem propitious for popular summaries of recent advances in molecular physics, and a large number of osuch books, appealing to various circles of readers, have recently appeared, some of which are now before us.
