The section on actinium consists of but 34 pages, and the literature search for it was conducted through 1959. Modern treatment has been given to its isotopps, nuclear properties, preparation, separation, and chemical properties. The literature searches for the rareearths were not conducted systomationlly beyond Ilecernbcr 31, 1954, in most cmes.

The Symposium on Microohemistry held a t Birmingham University in August, 1958, was attended by over 400 analytiral chemists including 110 from 25 countries outside the United Kingdom. Many of these participated in the evten~ivcdiscussion6 whirh are report,ed after most of the 60 papers in these proceedings. R. C. Chirnside's remarks on page 408 are worth quoting: "At the outset I must declare myself a heretic for I have newr been completely eonvinecd that there is such a thing as microchemistry or even micrachemicnl analysis. To what indeed does the 'miero' refer; to the chemistry, to the sample, to thc quantity of the suhstance to be determined, to the size of the apparatus, or even to the stature of the analyst? Having studied the whole programme of the Symposium I am no nearer a definition; indeed the range and variety of topics and techniques discussed are such that I am confirmed in my heresy." With t,his concession in the uae of the term "mieroehemistry," the reader will enjoy the authors' accounts of their research on nearly every analytical technique thslc can be considered "micro" in n.nv sense. Included are evaluations.

well written-ven the foreign papers have been cast in the style of the English authors. Major topics and authors are: Quditative Micro-analysis, Feik, Weleher, West, and Weisz; The Decomposition of Organic Matter, Diehl and Smith, and Pijck, et al.; Weighing, Hadsman and Corner; Classical Methods far the Determination of Elements, Groups and Physical Constants, Lieb, Schoniger, Malissa, Colson, Levy, Kirsten, Hersch, Ma, Veibel, Stephen, and Sobotko; Biochemical Methods, Adamson and Simpson, Nicholas, and Rosen; Chromatography, Crouch and Swainbank, Grand-Clement, (Continued on page A181)

This rdit,ion ss mcll as the previous pul,liention is primarily aimed a t those persons drriruns of knowledge of crystals, their growt,h, and st,udy.

I n vipw of thc diminishing numhcr of t,rained and qualified optical microsropifits this book mnkes n good attempt to explnirl to the readcr the vslushlc but, also rather diffirult science of crystals, their t,r;tnsforrnntion, am1 methods of study by thc use of rather little known ( t o thc non-microscopist) equipment. Tho 13 chapters m ~ d544 pages of this pulhv,tion (12 chapters and ?(i2 pages in thr 2nd exlition) contain in general most of the information present in the previous edition. There has been some rearrangetnent of topics to e r ~ a t eanother chapter nnd to p r w ~ n xt mom logical arrangement of infomation.

This book combines tho basic conropts of classienl physical ehrrnistry with . z p plicat,ions t o pharmacy and medicine. Methods used in measuring the ghysiralchemical constants of medicinal chemicals mnkes the tpxt i n v d ~ ~ n hto l e thp st,udy of pharmacy. The basic physical chemistry concepts are presented in such n way t h a t the student is able t,o apply them t o problems involving standardization, stnbility and ahmrption of r h g ~ and rlnlp products. Numerous examples of w r h applications are t,o he found in the text. Although the calculus is u ~ e din the derivation of several of the fundamental equstians, i t is not a prerequisite to oeing the hook. The explanations given anrl the problems included require only freshman mathematics for their understanding and solution. The text is wII written on g w d p n r w and is well ilhlstmted. Wide use of tables and line drawings lend t o the easc of nnderstanding. I t is upto-date in all resperts. Despite thc fact that the text is written primarily for pharmacy sttrdents and manufneturing pharmacists. i t rervcs alzn as a n ideal text for use in t,he premerlienl program as well as in any lxginning ronrse in phynieal chemistry. The cmphilsis on drugs and problems involving dwgs makes the text roadable and interesting to most students of physical chemi~try.
