The German medical profession has made available a system for practically every aspect of medical practice and now offers a systematic guide to the building and control of the hospital. This appears in six volumes. The first volume deals with the general hospital; the second with special hospitals; the third, with operating rooms, x-ray rooms, pathologic and serologic departments, medical and general libraries, and similar special features of all hospitals. The fourth volume has not yet been made available. The fifth volume concerns the organization and technic of hospital conduct, and the final volume deals with nutrition and dietetics. As might be expected, each of the contributors has done his utmost to cover his subject fully. For those workers in the hospital field who can read German, the volumes will be replete with a vast amount of valuable advice and suggestions.
