According to the author, "Biochemistry may be comidered the chemist's view of biology" (p.2), n, most onnsnal definition: similarly we could define organic c1iemistt.y as imrganie chemist's view of carbon cumpounds, a definition to which nu organic chemists would subscribe! Ileithel's definition is quite different from that used by practically all biochemists (e.g., Karlson: "Biochemistry is one of the life sciences. Its object is to study the phenometrn of life by chemical methods"). Accordingly, the chapters dealing primarily with biological phenomena are the least satisfactory and could have been omitted altogether. The process of growth is much too complicated to be treated on five pages (including graphs and structural formulas) and it is not erclnsively the problem of I)NA and RNA (it is impossible to throw into one basket the various types of growth: multiplicative, auret,ic and secretionary): he does not even quote the most important literature on the subject, like the now classical

Charts, d i e grams, and tables are extensively wed in clarifying points and concepts. Cansiderilble material is conveniently summarked in table form. The coverage of topics are far from being superficial, and frequent inclusion of current research topics makes the book relevent to the problems confronting modern biochemists. W I K T ~W.

The chaw ter on membranes is t o t h e greatest extent devoted to bacterial membranes and only mentions cellular membranes in the multicellular organisms. The author failed t o correlate the chemistry of membranes with the living functions and practically did not discuss the role of membrane structure in permeability. In summary, as a textbook of biochemistry, Reithel's book is unsatisfactory; however, as a "chemist's view of biology" can be very useful.
