The purpose of the author is to compile a volume which is primarily devoted to the pathogenesis, pathologic anatomy and histology of traumatic lesions which have not hitherto been adequately treated in the literature. Topics which have been satisfactorily considered are discussed briefly in the interest of completeness. The general plan of the book is satisfactory, the chapter arrangement beginning with a general consideration of mechanical injuries including various types of trauma: gunshot wounds, stab wounds and injuries due to blunt force. Other sections are devoted to trauma and infection, trauma and tumor and then follows a discussion of the lesions of the various body systems, special organs and tissues, their complications and sequelae. Attention has been given to controversial questions, notably in the chapter on trauma and tumors and in the discussion of the productive mechanism of cerebral concussion, and Moritz's reasoning is in agreement with generally accepted opinions.
