Science Is Bulwark of Health Says Medical Head. Great open spaces still exist president of in mankind's knowledge about keeping - well, Dr. Charles Value Chapin, the American Public Health Association, told the thousand delegates attending a t the opening session of the Association's recent annual meeting at Cincinnati. "What is not known about maintaining and perfecting the health of mankind is far greater than what is known," he declared. "The opportunities for discovery are as great today as before the days of Harvey, Pasteur and Lister." "Today we enjoy freedom from most of the great plagues of the world, but we have little thought of the thousands whose scientific labors, accompanied perhaps by exposure to deadly germs, have conquered disease and saved countless human lives. But even now them is the greatest need far further scientific investigation. "The science which can point to its achievements against smallpox, malaria, yellow fever, diphtheria, typhusand typhoid fevers, tuberculosis and a score of other diseases, as well as to a rapid lengthening of human life, and especially to the saving of =st numbers of infants from early death, need not be ashamed to admowledge that some experiments have failed."-Science Set-%e ~
