Tms is a text book designed for the use of medical students. I t includes a unique selection of material with emphasis an subjects usually studied after a preceding course in biochemistry. Extensive treatment is given to cancer (an entire chapter), to chemical aspects of reproduction and heredity, to pathology and to the ehemistrv of infection. Even the descrintion of vitamins is included along with deficiency diseases as an'aspect of pathology. With so much space given to the chemistry of disease, the fundamentals of biochemistry are treated briefly. Carbohydrates sre presented in 16 pagea included in the chapter on Tissue Chemistry. Similarly, lipids are allotted 10 pages and the sterids with steroids 8 pages in the same chapter. The first chapter is on proteins and amino acids and is followed by one on theories of protein structure.
