The writers in their preface state the reason for this book: "It has seemed to the present authors that these diseases and disease manifestations form a logical field of interest which could be well covered in monographic form, and the present volume is the result." The authors, experts in the field, have done an excellent job; the monograph is well written, well and profusely illustrated, and finely printed on good paper. The discussions are up to date, and there are excellent bibliographies. It is of interest that chicken pox and zoster are taken up together, although the elaborate chapter on herpes simplex is separate. Measles, German measles, roseola, infectious mononucleosis, dengue, fourth disease, and fifth disease are thrown into one chapter. The book is highly satisfying.
