“…In 1909, the year preceding Dr. Lederle's appointment, the death-rate was 16.21. In 1910 it was 15.98 ; in 1911, 15.13 ; in 1912, 14.11 ; and in forty-eight weeks of 1913, 13.52. At present, therefore, New York is exceeded in this particular only by London, among the great cities of the world, and its rate now closely approximates that of London.…”
