BOOK REVIEWS 521 The second chapter covers the principles of rotational viscometry thoroughly and well. The section on general design principles is es- pecially valuable to the rheologist as a check-list for instrument evalu- ation. The third, fourth and fifth chapters describe and compare com- mercial rotational, capillary and mis- cellaneous types of viscometers, re- spectively. The treatment is full and detailed, including the usual experimental procedure for each, suggested modifications and in- tended uses. The disadvantage of the description is that not all points of comparison are touched for all instruments. The final chapter discusses visco- elastic phenomena. The handling of this subject is quite capable. It will probably not be of value to the cosmetic chemist unless he has re- duced his knowledge of the basic concepts of simpler types of flow to familiarity. The cosmetic chemist will find the major deficiency of the book to be the emphasis on mathematical treat-- ment at the expense of an explana- tion of flow phenomena on a molecu- lar structure basis (an emphasis in- tentionally placed by the authors). Also, the description of emulsion types and problems associated with different flow and viscosity patterns is hardly touched. The point of view is generally not that of the emulsion chemist, as is to be ex- pected by the background and aims of the authors. Nevertheless, the book is valuable for its clear, con- cise treatment of rheology from theoretical and instrumental as- pects. Other good features are its freedom from errors, an explanatory table of symbols, a comprehensive bibliography and a fair index. It is a text worth having.--H. JAss, Revlon, Inc. NEw GF. RMAN-ENoL•SH DICTIONARY FOR CHEMISTS by H. H. Neville, M. C. Johnston and G. B. Boyd, D. Van Nostrand Co., Inc., Princeton, N.J. 1964. 330 pages. Price $8.95. Despite the similarity of titles, this dictionary differs from most German-English dictionaries for chemists because it includes an unusually large number of non- technical German words. In order to keep the size of the dictionary within practical limits, some tech- nical terms were necessarily de- leted from this volume. In the opinion of the reviewer this re- duction in size has been achieved by deletion of words which are practically identical in both lan- guages and thus does not detract from the comprehensive scope of this dictionary. A quick count indicates that there are approximately 35,000-40,000 entries, significantly fewer than those in many standard dictionaries designed for use by chemists. Nevertheless, this dictionary should be satisfactory for the needs of all chemists who have only a passing acquaintance with the German lan- guage. The readability of the dictionary might have been improved through use of larger type, and a slightly bet- ter grade of paper might have been used. These comments in no way impair the utility of this volume, and it can be unequivocally recom- mended to those who have need for a German-En,•,lish dictionary.--M. M. RIEGER, warner-Lambert.

522 JOURNAL OF THE SOCIETY OF COSMETIC CHEMISTS doing this work an injustice. This is not a second edition but primarily a collection of essays on important aspects of protein chemistry which had not previously appeared in the first edition. The editor must be congratulated on having excluded from this "second edition" most material which had been presented in the first edition. The book is made up of six chap- ters, all of them written by experts in their respective fields. The first of these, by Light and E. L. Smith, is concerned with the analysis of amino acids in peptides and pro- teins. This chapter, together with the addendum by Tristram and R. H. Smith, is a brief introduction to problems and new techniques of amino acid analysis. Chapter II by Hoffmann and Katsoyannis discusses the labora- tory synthesis of peptides of bio- logical chemistry. This chapter is the first comprehensive review of this important subject and should be a primary source of information for all who are interested in this field. In contrast, Chapter III is con- cerned with the synthesis of pro- teins in biological organisms. This chapter, by Fenton, is a most im- portant addition to the volume be- cause it summarizes up-to-date knowledge of the problem of the pathways of protein synthesis in living systems and how they are in- fluenced by nucleic acids. Chapter IV, which discusses the determination of the primary struc- ture of proteins, should really have preceded Chapter II because with- out knowledge of the amino acid sequence the synthesis or duplica- tion of biologically active poly- peptides in the laboratory is, of course, impossible. This field of investigation has attracted a large number of investigators during the last decade, and this review by Canfield and Anfinsen discusses the methods of cleavage of proteins and details the amino sequences of a number of proteins. Chapters V and VI are concerned with intramolecular bonds in pro- teins. Chapter V discusses "The Role of Sulfur in Proteins." This title is somewhat misleading be- cause this chapter by Cecil discusses only the role of sulGr in soluble pro- teins and makes no mention of the contribution to the sulIhr chemistry of fibrous proteins made by the Australian group. The primary em- phasis in this chapter is on analytical methods and chemistry of the SH or SS function in protein molecules. The final chapter is concerned with noncovalent bonds in proteins. This mathematically oriented con- tribution by Sheraga is one that most chemists and biochemists will have great difficulty in following. The contribution of hydrogen bonds, ionic bonds and hydrophobic bonds to protein structure is discussed from a statistical-mechanical point of view. The major portion of this chapter presupposes a working knowledge of thermodynamics and statistical mechanics. The impor- tant effect of noncovalent bonds on the structure, denaturation and modification of proteins cannot be over-emphasized. Extensive up-to-date references follow each chapter, and the volume includes an author index and a very comprehensive subject index.--M. M. RJEG•R, Warner-Lambert.
