FOREWORD

To one who has been an eye witness of the wonderful achievements of American medical science in the conquest of acute communicable and pestilential diseases in those regions of the earth where they were supposed to be impregnably entrenched, there is the strongest possible appeal in the present rapidly growing movement for the improvement of physical efficiency and the conquest of chronic diseases of the vital organs.

Through the patient, intelligent and often heroic work of our army medical men, and the staff of the United States Public Health Service, death rates supposedly fixed have been cut in half.

While it is true that to the public mind there is a more lurid and spectacular menace in such diseases as small pox, yellow fever and plague, medical men and public health workers are beginning to realize that, with the warfare against such maladies well organized, it is now time to give attention to the heavy loss from lowered physical efficiency and chronic, preventable disease, a loss exceeding in magnitude that sustained from the more widely feared communicable diseases.
