A favorite indoor sport among physicians today is the "panning" of Paul de Kruif, whose enthusiasms frequently eclipse his judgment and perhaps sometimes even his powers of observation. His current enthusiasm is the system of medical care established by Henry Kaiser for the workers in his shipbuilding plants. At least two medical writers, Drs. George H. Kress in California and Western Medicine and Floyd T. Romberger in the Journal of the Indiana State Medical Association have meticulously picked this book to pieces and left of it little of virtue. Those readers who think it worth while may refer to these contributions to confirm the opinion that the book is more propaganda than qualified sociological or medical study.
