The English version of Volume II of Brauer's"Handbook" follows the path of the very well received translation of Volume I. Again,some of the material and particularly the bibliography has been corrected and brought up to date. The nomenclature has been re-vised where necessary, with the Stock and the Stock-Werner systems (the practice of using Roman numerals to define oxidation states of atoms) adopted as much as possible. This conforms with current I. U. P. A. C. and Chemical Abstracts practice [for details of this see Robert C. Brasted, J. Chem. Education 35, 136 (1948)]. The references to laboratory equipment and techniques reflect current U. S usage, but useful European methods have been retained..
