In the preface to the first edition, Dr. Ellis states his objective, which is "to emphasize those features of the young and growing individual which will determine his response to the impact of disease processes, and distinguish this response from the behavior of the adult whose development is complete or whose organs are already suffering degeneration." He further states that "this book is not intended as an inclusive work of reference, but rather as an introduction to clinical pediatrics for those who are already familiar with the natural history of disease processes in adult life."
Dr. Ellis has created a textbook of pediatrics amply fulfilling his objective. In no sense is his book designed to compete with the encyclopedic texts of multiple authorship. Nor is it written as a handbook of pediatrics. It is indeed an introduction to the subject with the advantage of single authorship and a unified approach.
