This book is divided into eight sections. The subjects of these are hematologic terminology, the development and morphology of blood cells, leukocytosis and leukopenia, the anemias, the leukemias, hemorrhagic diseases, miscellaneous diseases and hematologic technic. Thus the entire field of hematology is thoroughly covered. Every condition discussed is illustrated by a colored plate showing the type of cell involved. As these drawings are made from specimens prepared with Wright's stain, they have a universal appeal. An immense amount of material is incorporated in this volume, and the authors have been fair in stating the composite opinion of American and European authorities. The idea of including in one volume both the clinical and the laboratory aspects of study of the blood is excellent. This book should be of great value to any one interested in diseases of the blood.
