This book is the only complete table of experimental dipole moments measured up to 1962. It contains values for about 6000 compounds, accompanied by 2178 references. The data are presented in three tables: inorganic compounds, organic compounds, and compounds with undefined formulas (polymers, mixtures, etc.). The method of study, solvent, and temperature are indicated for each case. The classification is done by molecular formula, and the book's clear and attractive presentation makes it easy to consult. Dipole moment analysis is an important method for determining molecular structures. For crystallographers interested in comparing their X-ray diffraction results with those from other methods, this book will be very helpful. The second volume of Silicate Science covers glasses, enamels, and slags. The author's 1954 work was a comprehensive overview of silicate science, but due to rapid advances in knowledge, a new edition was not possible. Instead, a supplement was published from 1952 to 1962, divided into five parts. Part II covers silicate glasses, including new measurement methods, experimental results, and structural studies. It also includes industrial applications of glasses and enamels, and industrial slags. The book contains over 2000 references, providing a comprehensive overview of the field. While some hypotheses or experimental data cannot be critically evaluated, the book is a valuable resource for silicate research. The author is thanked for his extensive work, though the title could be more precise. The Transactions of the American Crystallographic Association includes proceedings from a symposium on accuracy in X-ray intensity measurement. The first paper discusses absolute intensity measurement on powders, while others address the R-factor, extinction corrections, and background factors in crystallography.This book is the only complete table of experimental dipole moments measured up to 1962.
