This book is devoted solely to ferments and particularly to the ferments found in the animal body. It is especially valuable for workers and investigators in the field of fermentation. Methods of preparation and the determination of activity are treated quite thoroughly. The book has an adequate index. The language is simple, the style clear and direct. The literature quoted is not voluminous but is carefully selected. The volume is divided into two parts, general and special. Under general properties the author discusses preparation, adsorption, elution or the freeing of ferments from combination, dialysis, electrodialysis, conservation, measurement of activity, specificity, influence of temperature and reaction, activating and paralyzing agents. Details of chemical and physical processes and methods are described clearly and accurately, so that the laboratory worker will have little difficulty in carrying out the methods. The special part is devoted to the methods of preparing and studying the action
