ionization constants of weak electrolytes, their temperature, coefficients, and the ionization of weak electrolytes in salt solutions. The appendix contains a fund of information in the form of tables. The author index is indicative of the great number of references to the work of others, and the subject index adds greatly to the work for reference purposes. The book is an authoritative resume of the state of the subject. An American Chemical Society Monograph, it stands alongside of other works of this nature in pointing the way to a more complete knowledge of the subject covered. R, H. OPPERMANN. INORGANIC CHEMISTRY, by Fritz Ephraim. English edition by P. C. L. Thorne and E. R. Roberts. 92! pages, illustrations, I6 X 24 cms. London and Edinburgh, Gurney and Jackson, 1943. Price 28 shillings. This very fine work, which is now in its fourth edition, is not at all the type of inorganic chemistry textbook to which we are accustomed. It is not merely an amplified reference list of inorganic compounds but is rather a truly theoretical study of the background of inorganic chemistry. The general scheme, so successful in earlier editions, has been retained in the present work, The chief section headings are: I--Elements 2--Halogen compounds 3--Oxides of hydrogen and of the metals 4 - - T h e compounds of sulphur, selenium and tellurium 5--The nitrogen, phosphorus, arsenic group 6 - - T h e elements of the fourth group (and boron). The materials of inorganic chemistry are dealt with collectively rather than individually, which results in making the book very convenient for the reader. Formulation of compounds is strictly according to modern structural ideas, considerable use being made of electron formulae. In the opinion of the reviewer, this book is one of the outstanding works on inorganic structural theory and is a valuable addition to the library of the chemist. G. S. GARI)NER.
