The standard of thoroughness and clarity of presentation set by the first section of this reference work previously reviewed in The Journal has been well maintained if not surpassed in the present volumes. Section II continues the description of substrates, with papers on starch and glycogen and their split products, the uronic acids, the hexosephosphates, nucleic acids and polypeptides. The excellence of presentation is assured by the choice of the respective authors, e. g. Hirst and Peat on ascorbic acid, Abderhalden on polypeptides, and so on. Section III deals with the various methods used in the analysis of substrates, products and enzymes. These include, among others, roentgen ray analysis (Astbury) and the use of the polarigraph, ultracentrifuge methods (Lamm). Redox-potential measurements are described by Jörgen Lehmann. Chapters on the setting of the experimental conditions to be observed in enzyme work close this volume. Section iv continues with a detailed description
