BOOK REVIEWS discussion, evaluation, and correlation of methods applying the phenomenon of differential migration of charged and uncharged particles in general. .4lmost 70 references lead the reader to most of the recent summary works in the fields of chlorophyll pigments, emotenoids in plants, photosynthesis, and chromatography, to original articles of a. number of investigators, and necessarily to Strain's publications, which form the basis for this lecture series. Throughout the book clear line drawings illustrate the sequences of zones in the vmioua rhmrnatogrems. Far many pigments, diagrams af the eharacteristio spectral absorption curves are furnished. Only about a dozen typographical errors were noted by the reviewer, all minor, except possibly the confusion of neoxanthin and violaxanthin on pages 76 and 77. According to the Foreword one of the qualifications of a Priostley lecturer is "the ability to present his material so that it ia intelligible and stimulating to the college junior as well as interesting and informative to specialists in narrower segments of the name field." Strain has handled this part of the assignment very well.

The text contains the 23 papers presented before the Congress a n Modern Analytical Chemistry in Industry arganised hy the Scottish Seetion of The Society for Analytical Chemistry which was held a t the University of St. Andrews in June, 1957. The Congress was divided into 3 sections: I, Analysis in Modern Industry (8 papers); 11, The Application of Some Newer Analytical Techniques in Industry (9 papers); 111, Developments in Analysis for New Problems in Industry (6 papers). The papers are extremely well written and present an up-to-date picture of research and analytical chemistry in the industry of Great Britain. Only one contributor was from the United States (Professor G. Frederick Smith). The tables and figures are of goad quality. Representative titles of the papers are aa follows: Modern Analytical Methods in the Iron and Steel Industry, Emission Spectroscopy in Industrial Analysis, Modern Analytical Chemistry and the Rarer Metals, and The Geochemicd Approach to Prmpeeting for Minerals. Moat of the papers include a list of references well as P A U LROTHEMUND the results of an informal discussion sesBoz 64 sion.

This useful little hook was written "with the object of collecting all the published data on the elements from polonium to actinium into one volume and to give some account of the methods used for the study of their chemistry." I t would appear to have succeeded remarkably well in its goal. Certainly anyone who wishes to become familiar with the chemistry of these elements (Po, Bt, Fr, Rn, Ra, and Ac) will want to look a t this volume carefully. The style of writing is concise and clear and appears on perusal to be sccurate. I t is enriched hy the author's own researches and experiences. Misprints and other similar errors are few. On the whole the bonk is very interesting. I t may even stimulate mare adventurous s o u l ~ i n t otrying to obtain these ~ubstar~ces to fill some of the admittedly large gaps which still exist in the knowledge of these elements.

Maz H a n s a , Managing Direotor, MetThis reviewer has only one point to offer which it is believed would have contributed a great deal t o the usefulness of the work. As it stands. the volume is simply a well-organized collection and summary af literature. Thus, as an example in the chapter on radium, a "calculated" heat of reaction of radium with water is given a8 90 kcal/g atom; yet the standard A H " for Rat+(aq), a much mare fundamental quantity, is omitted. A deposition potential for radium is given a8 -1.718 v (calomel) (which must surely correspond to oxide and/or hydroxide formation) although the st,andard reduction potential of -2.92 v is not listed. No mention is made of the atomic weights of mdium (and the other elements) derived from nuclear decay data, although such Sources almost always lead to a more accuratte value. An estimated ionic C I ~ E talradius for Rat+ is given as 2.45A in the same sentence with an experimentally determined one of 1.52 A from RaF2 with no comment as to the validity of either. One would have hoped that a more scholarly and selective appraisal of the literature could have been made by a. man so obviously a leading contributor to the field.

Seldom does one find as complete a reference u-ork as this in a ~inglcvolume. The data are recent (some 1957 items are included), inclusive (1286 systems are covered), and conveniently presented (the 684 phase diagrams are in atomic per cent rather than weight per cent). Crystallographic data likewise are provided with a completeness that includes lattice spacings of intermediate phases. The reader is impressed by the vast amount of informstion which must have been critically evaluated in the preparation of this work. The following is typical: "According to thermal, microscopic and electrical investigations and roentgenographic measurements. . . ." Obviously the specialist will find this book indispensable. I t belongs in every academic lihrmy whieh provides complete reference enversge of chemistry and related fields. Even students in elementary physical chemistry courses should discover this compendium of information at the same time they discover the phase role.

This second volume about rheology, the science of deformation and flow, not only includes more about theoretical treatments but also dedls ~specificslly with organic glasses, raw elastomers, cellulose derivatives, fibers, snd asphalts. Also there is a chapter dealing with the earth's interior whieh, interestingly enough, followa the general principles "derived from the study of less 'immohile' objects." I n Chapter 111, T. Rhee and H. Eyring present their relaxation theory of transport phenomena with much evidence to show its general applicability. The theory encompasses more than any other and is a partial answer to the cry raiaed in Volume 1for a generalized theory of flow and deformstion. There are two chapters on experimental techniques-me on fluids that overemphssizos the utility of the concentric cylinders method for obtaining viscosities and one about measurements on viscoelastio bodies. The chapters in the second volume appear to be more uniform in style and outline than those in Volume 1 (see THIS JOURNAL, 34, A284 (1957)). There are even fewer obvious errors, although the (Continued on page A110)
