THIS~ e c m dedition of what is known as "the sbandard work on sewage treatment" has been completely rewritten. This book is not a treatiae; yet, presents in a, eonci~e (and oeessionally too abbreviated) manner modern day theory and practice of sewage treatment. The authors have gsthrred a wealth of facts and information and arranged the material logically into eighteen chapters. For example, Chapt,er 2, Composition of Sewage, Chaptea. 5, Chemical Precipitation, Chapter 10, Chlorination, and Chapter 16, Water-Borne Industrial Wastes, well illustrate the scope
of the m a t e d . Simple arithmetical calculations are employed with frequent, examples given in order to illustrate the use of various formulas and eqnatians. Figures are logihle and easily under8t00d. A negligible knowlcdgr of chemistry is cxpeeted of users of this hook. The hrief chemistry included is not always consistent with modern day usage. Erroneous or incomplete portions include: "the molecular weight of hydrogen is 1.008," tho nsc of mol instead of mole, and 2Fci++ 60H- s FulOs.xH,O. Some references are given its footnotes in the tcxt, and Appendix I cansintn of general rcfcrunces and s rather complete rhapter-by-chapter bibliography. .4ppendix 2 eonsist~of s lint of ahlreviations, symbols, and conversion tahles for various weights and measures. An adequate index is present. This new edition will be of value to
+
operators of sewage treatment plants and students of sanitary engineering. J A M E S M. P A P P E N A A G E N KENIONCOLLEOE Gnhlntm,

WIT^ the appearanre of Vdume 111 in this exeellmt series of volum~s on organic analysis, the editors and authors have again made a valuable contribution to the chcmical review literat,ure. Many tedious hours of literature search are eliminated by the comprehensive and critical treatments of functional group analysis provided in the throe available volumos. The present work includes six chapters-(I) Lktermination of Organic Acids, i.e., macro and semimicro method8 for determining carbonylic acids, sulfonic acids, phenols and related compounds; (2) Determination of Acid Anhydrides; (3) 1)cterminatiou of Amines and Amides, and including imidos, imines and quabernary ammonium compounds; (4) Iletcrmination of Olefinie Unsatumtion; (5) Analytical Mass Spectrometry; (6) Sgnthetic Organic Costing Resins, with emphasis on characterisation and determination of some commercially important elnsscs-and brings the numher of broad topics discussed to a total of 24. The cumulative subjoot index of Volume I1 has here been expanded to a convenient 38-page indcx covering all thrco volumes. The general scheme of the individual authors has remained the same: to survey the analytical literature and ~ r o v i d eample bibliography which may he consulted for det,aile of less widely useful analytical methods, and to limit their discufisions of detailed procedures to the mare import,ant, widely applicable methods. The concern is not only with functional group determination in pure campounds and simple mixtures, hut. dno wibh determinations that can bc used for mixtures and pure compounds eontaining interfering funetion~lgroups. More than one-third of the text of the present volume is devoted to determinations of olefinic unmturation, because of the great mass of literature available in thin field and herause the authors of the chapter feel that the whole subject, including both the newer chromatographic and ~pectroseopie techniques and the older classical methods, can he beneficially reviewed. 0 1 the 2000 articles in t,he chemical literature which came to the authors' attent,ion, 698 have been included in their bibliography, and the chapter contains a six-page table of recommended methods, with helpful general comments, for determining each of the large variety of types of olrfinia unsaturztiotion. This is an example of the care and commendahlc thoroughness with which the topics in this volume, and in the previous volumes, have been treated. FRANCES BERLINER
