A previous review in these pages concerned volume I of this series of 42 case reports. The reviewer is favorably impressed with the choice of the cases and the complete analysis of the roentgenologic, anatomic and clinical aspects. Differential diagnosis is thoroughly considered. Many of the cases are gastroenterologic, but a number of documents relate to osseous pathology. The photographs of the anatomic specimens add to the value of the presentations. This series of "dry clinics" is presented on a high plane of scientific excellence.
