observation. The student report includes a serieli of essay questions which require careful obsemation and interpretation of data. It is also suggested that the student report include equations for all the reactions involved. The experiments are a little more sophisticated than thhse found in the usual high school laboratory manual. Excellent suggestions are contained in the teacher's manual. These include a general commentary on each oxperirnent, lists of chemicals for each experiment, a quantitative list of chemicals needed for the entire course, apparatus list for the student locker and additional equipment needed in the laboratory. A list of stock solutions and their DreDaration is also included.

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
