Abstract
THE volume under notice is especially characterised by its eminently readable style. The subject is dealt with exhaustively, yet the material is presented in such a way that an honours student could read the whole with profit, whilst the expert will find full references to recent work apart from the detailed treatment in the text. Methods of separation and tests are dealt with as well as the chemical properties of the elements, and the names, occurrence, and composition of the minerals. The book will be welcomed by chemists, and is well printed, and provided with an adequate index. Theoretical considerations of classification and atomic structure are considered, but a just sense of proportion has been preserved. The book contains all the information that the chemist who is not a specialist in this department will require.
