MCBAINhad planned to write a book on the subject of solubiliaation. After his untimely death, the authors decided that it would not do justice to his memory to l e m the monograph unfinished. This book deals with solubili~ation,wherein particles of s calloidsl solution "take up and incorporate within or upon themselves the otherwise insoluble material." Chapter 1 is a historical background which briefly reviews renorted observations of the nhenamenan of solubiliaation. In &mt,er 2. model exoerimenis are described as an aid to the
chosen peneralizations, but also because of the authors' evaluations af%onolusionsdrawn by others writing in this field. The chapter on practical applications is quite unsatisfactory and not in keeping with the high standards of critical evaluation used throughout the book. Discussions on detergency and dyeing indicate that the authors have given very little thought to these subjects. On page 81, Triton X-100 and Carbowax are incorrectly given ss polyethylene oxide-fatty acid compounds. The distribution coefficient given on page 140 as 43.9 should read 4.39. However, errors are relatively few. This reviewer is of the opinion that m y student of surface chemistry or anyone working in the field will profit from a careful reading of this book. LLOYD OBIPOW

trolytes may be studied. Chapter 4, called Data and Facts of Solubilization, is 102 pages long, more than two-fifths the size of the entire manuscript. In addition to presenting end critically evaluating a considerable quantity of published data, the authors deduce generalizations which add considerably to the value of the publication. They conclude that solubilization "beers very close resemblance to the uptake of material8 by bulk phases, exhibiting supersetursi tion, variable rates of attainment of equilibrium, etc., just az in bulk phases, and that the treatment of micelles a8 pseudo-phases is both formally and physically justifiable." Chapter 5, on the Mechanism of Solubiliaation, is an excellent analysis of available information concerning the size and shape of micelles. Chapter 6 discusses "ca-solvency, blending, and hydrotrapy" and compares these phenomena with solubilisation. Chapter 7 is concerned with the "physiologieal aspects of solubilizs,tion," and Chapter 8 contains a very brief discussion of "some practical applications of solubilisation." The manuscript concludes with an appendix on "the theory of light scattering," and another on "the behavior of polysoaps." Some 335 references are given; B few are as recent as 1954. This book is not a complete compendium of published solubilization data. but rather a criticd evaluation of such data.

F o ~ ~ o w the r ~ asame pattern as its predecessors, this latest volume presents the descriptive chemistry of groups II-B and III-B. The title remains somewhat deceptive in h t the modifier "comprehensive" refers not to the treatment of the subject but to the subject itself, i. e., all of the elements of the periodic table will be covered eventuallv in this work of 11 volumes. Folloaing an intnrluctim uhirhinvludrs n l~iitclrirnll~ackground and asurvry of the nerurrencrs in naturr, the r.1wrniral and plny~icnl propwties of thc clrmmt, as well M iLs more impomnt compounds, are considered.
