An excellent reference volume or textbook on pathology has been compiled by the editor with the assistance of 31 collaborators who prepared 46 chapters supported by nearly 1200 illustrations including 10 full page color plates. Introductory chapters include the subjects of behavior of cells and inflammation. Another section on general principles deals with infection and resistance. Metabolic disturbances which concern fat, carbohydrate, protein, minerals and pigments are considered in a fine discussion by the editor.
