Alcohol Addiction and Chronic Alcoholism

ordinarily found in hypertrophic arthritis-in spite of the fact that none of these patients had given a history of knee-joint symptoms. The book contains a complete description, both gross and microscopic, of these joints. There is a series of 31 plates showing photographs-gross and microscopic-of a selected group of the joints at varying ages with several x-rays included. The book is well written and contains an extensive bibliography as well as a chapter devoted to "Etiological Considerations." M. S. EVELETH. For students undertaking the study of bacteriology as a science in itself this textbook can be enthusiastically and unreservedly recommended. Not only does it give clear and discriminating discussions of the r8les played by bacteria in the many fields which touch man's life, but it presents in such chapters as those dealing with the nutrition and physiology of bacteria basic facts which are too often skimped in texts. The emphasis on chemistry, evident throughout, is highly commendable and does much to give the book its outstanding character. This manual, although developed to be used in conjunction with the author's text->book, is well-fitted for most courses in general bacteriology. Its 94 well-designed experiments cover most fields of the sulbject, although comment might be made on the absence of any experiments, save for two on agglutination and disinfection, dealing with the pathogenic bacteria.
