" ... Of 3042 patients of all ages treated during 1894, 902 died--a mortality of 29.6 per cent.; whereas, of 3529 cases treated during 1895, 796 died--a mortality of 22.6 per cent.; the difference in percentage between the two rates being therefore 7.1. This, assuming that the former rate would otherwise have been maintained, represents a saving of 250 lives during the past year.

The reduction in mortality was greatest in early life.
