BOOK REVIEWS stitutions both in large and small degree depending upon the extent of adwncement in the different branches of chemistry according to the author's preface. The text shows most change in hiochemistry, textileehemistry, and radiochemistry for the reason given b y Dr. Meyer. These changes have been made without increasing the length of the sections. Certain pictures and diagrams have been omitted without apparent loss in the reviewer's opinion. The chemical structure of proteins and carhahydrates receives more emphasis. Some interesting applications have been added. The relationship is given between different blood groups and the heteropolysaecharides occurring on the surface of the red blood cells. In the textile field the information on detergents is expandcd to include new ones of interest to home economics students. Moreover, solid bleaches and fabric softeners are new additions to this section. Modernization has been effected by substituting more recent data in charts as well as by rearranging material, rewriting it, and adding exercises and problems. The section on atomic theory which includes radioactivity has been rearranged and rewritten in part. Numerous small changes appear throughout the hook reflecting a careful review of the material by the author in the light of chemical advancement as well as the reactions of students to the contents as noted above. The hook should appeal to those who found the first edition useful.
