This is a revision of the original volume, which first appeared in 1938. Added are chapters on prepayment health (or sickness) insurance and workmen's compensation laws. Both are well done. However, the former is already somewhat out of date because of the rapid changes taking place and recent actions of organized medicine. As the author points out, the chapter on medical careers other than private practice is somewhat obsolete, having been written before the war. This is equally true of portions of the chapters on specialization and on location. It might have been well, therefore, to withhold publication of the second edition until conditions had become more settled. Especially informative and helpful are the chapters dealing with case histories, planning and equipping an office, office personnel, technics and surgical instruments. It is quite evident that the author is much better equipped to write on these subjects than on business procedures.
