Simplification, ""pop"" style, of the advances of medicine which have either been the result of war, or are selected for this volume because they will prove invaluable in war time. Good material -- some new, some familiar. Shock treatment, plasma and the blood bank, the closed cast for compound fractures and its reduction of gangrene, Dr. Moorhead and the replacement of the X-ray with the ""locator"" treatment of burns, of infections with the sulfa drugs; plastic, brain and chest surgery; malaria and the new substitute for quinine; local anaesthesia. Finally, army medicine in practice, flight surgeons, field doctors, etc. Science simplified, which seems a popular gag these days.
