This is a conventional int.l.od1w3ion to the mthject a t hand, xpparently written primarily for Bribish and Enropean sludenta.

tion of this 4-vdume chemical eneyclope dia was reviewed here (44, A666, (1967)). The editor of the "Chemical Ilictiona~y" being reviewed here also completed the Lexikon after Riimpp's death and attached the latter's name to the present work not only as fitting memorial but also because an effort has been made t o me the ehar- acteristic thorough style of Riimpp. However i t must be stressed that the "Dictionsry" is not. merely a supplement, or abridgment of the "Lexikon" hiit an independent work, well able to stand on its

own merits. Though rooted in the "Lex- ikon," a much larger and comprehensive work, many items included in the four volrtmes have been omitted, such as bio- ernnhieal and industrial technical data.

In all, about 6300 items are treated in this book. Some are covered in a line or two, olhers deservedly are discossed over several pages. The material is all np-to- date; about .50yo of the items do not ap- pear in the 6th edition of the "Lexikon." The printed sources have been searched with care and almost 14,000 references lo the literature are provided, some as recent, as 1968. The book represents xn immense

International Series of Monographs in Analvtical Chemirtrv. ~ o l " m e 32, Analyticd Applications of 1,lO-Phen- anthroline and Related Compounds

Alfred A. Sehill, Northern Illinois Uni- versity, DeKalb. Pergamon Press, Ino., New York, 1969. viii + 193 pp. Figs. and tables. 14.5 X 22 cm. $9.

Within the stated purpose of poviding a convenient, extensive, and central somce of information on the varied uses of 1, 10-phenanthroline and related com- pounds in sndytieal chemistry, the author has achieved his purpose well. The material is extremely well-referenced and presented in s. logical, orderly fashion with balanced coverage. Chapter one contains a historical discussion along with the general properties of 1,lO-phenanthro- line, 2,2'-bipyridine and related com- ponnds. A rather complet,e discussion of t,he coordination chemistry of these compounds with Group 1 bhrough Group 8 met,sls is presented in Chaptpter 2. The preparation, properties, stability, and spectral charscteristiw of the metal com- plexes of these compounds are among the topics discussed in this well-referenced chapter. The use of these compounds as colorimetric reagents with many metals is discussed in Chapter 3 which also con- t,ains detailed procedures for most of the analyses discussed. Chapter 4 contains an extensive discussion of the uses of the complexes of these compomds as oxidat,ion-red~rction i n d i c a t o ~ with Chap- ter 5 discussing their applicat,ions as metat,hesis indieat,ors. The ose of t,hese compounds as precipitants is given in Chapter 6 followed by a discussion of some miseellaneons applications in Chqt ,er 7. The hook is eamplet,ed by a. short, discussion of the determinabion and recovery of 1,lO-phenmthroline and 2,2'- hipyridine.

The extensive tables of stahility con- stants of metal chelates, the rate const,ant,s for tbe formation and dissociation of metal chelaten, the oxidation-reduction potent,ials, the extensive compilation of acid dissociation const,antr of the ligand and related compounds, along with com- plete references to all of t,he pertinent literature makes this hook almost indis- pensable t,o anyone involved in 1,10- phenant,hroline research. A great deal of practical informrttian is also presented which should make this hook of interest to many practicing annlyt.ica1 chemists.
