There is no full and connected account of the progress of medicine during the Nineteenth Century, but the reader may consult with profit the various medical biographies, also the following works: Silliman’s “A Century of Medicine and Chemistry;” Jenner’s “The Practical Medicine of To-day; “Buck’s “Reference Handbook of the Medical Sciences; “Eulenburg’s “Real-Encyclopädie der gesammten Heilkunde;” the “Annus Medicus,” published in the Lancet at the close of each year; and Tinker’s “America’s Contributions to Surgery” (Bulletin of the Johns Hopkins Hospital, Aug.-Sept., 1902).
