This book, tvrittcn by the Chief Analyst anti a Technical Officer of Impcriat Metal Industries, Ltd., will bc received with great interest since it is a first-hand report by analysts of wide industrial cxpcricncc on the up-to-date procedures developed ancl confirmed in the company’s Research Department. Previous books dealing with this subject arc either obsolescent or written from second-hand information. In this book, the determinations of the common elements, some less-common clemcnts and g;tses arc dealt with in detail, but for some reason, clcmcnts such as calcium, gold, lithium ancf magnesium have been omitted. For each clement, there is $ashort introductory section and tllcn the practical procedures for different types of alloy ate given. Absorptiomctric (for 18 elements) and volumetric (for 12 ciemcnts) methocls predominate, but the share of time-consuming gravimetric methods is surprisingly large (for xo ckmcnts) and precipitation methods arc often used for sepnrations. Polurographic methods are usccl and are especialiy successful for traces of lead and bismuth, l’frc use of EDTA titrations is restricted, to the determinations of aluminium, nickel and zinc. A rapid proccdurc is given for alutninium, but for zinc an initial electrolytic separation of copperand precipitation of zinc with hydrogen sulphidc arc necessary and the authors have had to resort to an indirect final determination, EDTA titrations of load, tin and, zirconium arc not used. The most interesting chapters arc those dealing with the determinations of non-metals and gases in which low-prcssure, vacuum-fusion, combustion and evolution procedures are clcscribecl. absorption spctrophotoThe newest technique of analytical chemistry -atomic mctry -is rcprcscntecl by the determinations of cobalt, lead, sitvcr and zinc; information on the determination of other important clcments such as Al, Fe, Cd, Cr, Mn and Ni would have been of general interest hore. The electrolytic determination of copper is discussed very thoroughly; intcrfcrcncos and different means of overcoming these arc described. With regard to sampling, the authors give only some general comxncnts without going into detail; for example, scgrcgationof tin bronzes and mcthodsof avoicling thisare not mentioned. Clearly, every annlyticaf chemist will find something useful to this own practice in this book with its select& list of references. 1’1~~book itself is csscnti,al reading for metallurgical analysts.

The author hr~ briefly surveyed the basic relationships, the instrumentation, the analytical parameters, and the analytical applications in atomic absorption spectroscopy. This book is not inter&d for the atomic spectroscopist hut rather for the analyst who wants to know generally what atomic absorption spectroscopy is and “if”’ and “how” tltis method is applicable to his problem. The theoretician or experi&rai.
