Abstract
THE rapid development in recent years of micro-chemical methods of analysis has called forth an excellent series of text-books on various aspects of the subject and, of these, Chamot and Mason's “Handbook of Chemical Microscopy” holds a deservedly high place. In the second edition of vol. 2 now under review, most of the subject-matter in the original work (reviewed in NATURE, 130, 619 ; 1932) has been retained but a number of new tests have been included, some of them employing organic reagents such as dipicrylamine, nitrobarbituric acid and diphenylcarbazide. The most extensive additions have been to the sections dealing with the detection of the alkali metals, the metals of Group IV of the periodic classification and the anions of the sulphur group where tests have now been included for the polythionates ; a scheme for the identification of the various sulphur-containing anions has also been drawn up. To illustrate these new procedures there have been included forty-eight additional photomicrographs. All the photographs are excellently clear and the same care has been expended in making the descriptive matter lucid and yet concise. The text is remarkably free from errors, while there is a good index. The volume is handsomely bound, so that the authors and publishers have collaborated to produce a book which is indeed a joy to handle and to use.
