This book on pathology is remarkable for its clarity of style and its illustrations, which are wonderfully adapted to the text. The illustrations, some of which are in color, are taken almost entirely from material which the author studied in the laboratory. This edition has been thoroughly revised, but the general plan of the book is the same as that of the six previous editions. The general approach to the subject is from the point of view of etiology. Pathology must serve as an accompaniment or even as a foundation for the understanding of clinical phenomena. The importance of detailed study at necropsy is emphasized. All the chapters are followed by references to the literature. The book, which is intended for beginners, has long been a favorite among students and teachers.
