Abstract

(1) GAS analysis enters into almost every branch of chemical work, and there is therefore no need to emphasise the importance of a standard work on the subject. Prof. Dennis began his book as a second edition of the English translation of Hempel's famous “Methods of Gas Analysis,” but the inclusion in it of the advances made during the last fourteen years has turned it into a new book. Procedures for the determination of most of the common gases are given in considerable detail, but the book is rightly devoted mainly to rapid methods of technical gas analysis, including the determination of heating power as well as of quantity. The opening sections, occupying about one-third of the book, treat in turn of the collection, storage, measurement, and other manipulation of gases. The various forms of apparatus devised for gas analysis are described, a variety of important practical details being included. After describing fully the methods of analysis of the various simple gases, chapters are devoted to the investigation of flue gas, illuminating gas, acetylene, and air. Although remarkably complete, the book is not exhaustive; for example, no reference is made to Bone and Wheeler's valuable apparatus, first described in 1908. Only one of the automatic carbon dioxide recorders is described, whereas there are others on the market equally if not more satisfactory. However, these are only minor blemishes on a work which is likely to be widely used.
