The preface of this volume states that the author has endeavored to portray diseases as life under unusual conditions. The chapters on inflammation, cell growth, and the origin of tumors state clearly what is known on these subjects without going into unnecessary theories. The causes of infectious diseases are considered historically. Many illustrations are given of the discovery of pathogenic organisms by means of careful observation, experimentation and reasoning. The increase of disease in modern industrial life is emphasized as a check on the elimination of disease by the agencies of preventive medicine.
The book, though written for the general reader, may be read with great profit and enjoyment by the physician, for it is a philosophical as well as a scientific treatise on the most fascinating branch of medicine.
