B O O K REVIEWS graduate students who have progressed t o the point where they can profitably study from this hook, but i t is probably brst desmibed as a. graduate level text. Since only five and one-half pages arc devoted to the continuity equation, the KavierStokrs equations, and hydrodpnsmic boundary conditions, study from a book such as "Transport Phenomena" hy Bird, Stcwnrt, and Lightfoot would appear to he a prrrequisite to effcetive use of "Physicorlrrmiesl Hydrodynamics." Roughly the snnw amount of space is devoted t o stating the erpations of eonvectivc diffusion. Alt,hongh t,ho book is not suitable as a first trxt, in transport phenomena, s t least not without extensive supplementiltion, there is little doubt that many of the topics disrussrd in it will find their way into advanced courses. The book is not a. particulilrly handsnme volume. The equations were apparently reproduced from the original Russian edition and, as s. result, the symbols used in the text are somewhat different than those used in the equations. Furthermore, too many of the letters are improperly iormcd; for instance, there are eleven flaws an page fiva On first reading, elcven ohvinus typographical errors were detected in the first sixty pages, but other sections were bettcr. I n summary, "Physicachemieal Hydrodynamics" is undoubtedly a n important hook which will influence thinking and
research for many yearn to come. Wc are fortunate that i t has been translated into English.

Volume 9 and the eighth volume of Pascal's new treatise on inorganic chemistry are organized to cover the materids concerning elements of Group IV. This volume is devoted to titanium, zirconium, hafnium, and thorium. ChrEtian and Freundlich are authors of the section un titanium, Albert, Langcron, and Lehr of that on zirconium and hafnium, and Flahaut is sale author of the section on thorium. About half of the volume is reserved for the material on zirconium and hafnium, and the remainder is about equally divided betw-een titanium and thorium. Much emphasis is placed upon processes for the extraction and pmification of the four elements, particularly for those involving zirconium and hafnium. Much attention has been given to the bibliographies, and there are some 6600 (Continued on page A8301

Illustrations are employed frequently throughout the volume, as well as numwaus tables. Ten pages of indexes are included, but in general the indexes are not especially thorough, although metal systems are well indexed. This is helpful in locating various phase diagmms. The organization of the material on the elements and their compounds is well done, and this makes the volume an excellent reference source. Generally high standards have been maintained throughout publication of the treatise t o date, and this volume indicates that they are being maintained. ROGERV.

The Chemistry of the Lanthanides

The editors of the paperback series, Selected Topics in Modern Chemistry, have recognized in the lanthanides an excellent tnpic for one of their little books intended as supplements t o m y standard text in first-year chemist,ry and medo a wise choice in selecting Professor Moeller to write the book, sinre he is a lucid writer and an expert on this topic. The book is very well planned. The first two chapters cover the subject quite adequately for the reader who is seeking only general iniormation. The third and fourth chapters discuss chemical and technological matters in some detail, and the final chapter briefly presents the actinides as another series of closely related elements whose chemistry has rendered that of the lanthanides no longer completely unique. Professor Mocller approaches his suhjeet with a historical account that begins with the discovery oi a n unusual black mineral specimen a t a quarry a t Ytterhy by Swedish Army Lieutenant C. A. Arrhenius in 1787. The unraveling of t h e eomploxity oi the "earths" named yltria and aria is an object lesson in the rewards of infinite patienee. The historical account is concluded with a. section on the elusive element 61, which was finally identified in materials obtained a t Oak Ridge from the fission of uranium by Marinsky, Glendenin, and Coryell in 1947. In the serond chapter the essential oniqueness of the chemistry of the lant,lranides is related t o the uniqueness of their atomic structure. Here the reader (Continued on page A832)
