This is the American edition of the well-known Annual published in Bristol, England, for the last twelve years. The object of the Annual is to present its readers with "an exact and impartial record of the advances of medical science." In the rather successful effort to make the work truly cosmopolitan, the Annual has for some years past included among its contributors many American writers. For this volume we note the names of Hobart A. Hare, Wm. T. Buell, Paul F. Mundé, G. M. Hammond, H. D. Chapin, E. F. Frost, Frank W. Jackson, John Ridlon, J. Madison Taylor, Irving S. Haynes and John B. Hamilton. The Annual does not assume to make a report on all the medical literature of the preceding year, but takes note only of the " advances," or the progress made in medical knowledge of the subjects within the scope of the work.
