Dr. Tobey has written much in the field of public health. He collects here numerous essays covering the plagues of the past, the history of sanitation, the lives of Pasteur and Florence Nightingale, the development of the modern public health movement, and personal hygiene. His fact material has apparently been assembled from reliable authorities. Unfortunately, he is unable to make his story live, perhaps because his mind is more scientific than journalistic. All books of this character are inevitably compared with DeKruif's "Microbe Hunters," and because of the sense of the dramatic in that book all of them suffer by contrast. Unfortunately, the proof reading of this volume has not been careful, so that in some places the punctuation and the grammar are atrocious. The general reader in the field of health will find much in the volume that will interest him.
