This publication is an outgrowth of one published during the war under the auspices of the Medical Research Committee to keep British military physicians informed concerning advances in medical science as revealed in periodical literature. The publication includes collective abstracts on various subjects as well as abstracts of single articles which have seemed to the editors to be of special importance. The editors are: medicine, J. D. Rolleston, M.D.; surgery, W. G. Spencer, M.S., F.R.C.S.; pathology and bacteriology, W. Bulloch, M.D., F.R.S.; neurology, F. M. R. Walshe, M.D., and radiology, W. S. Lazarus-Barlow, M.D., F.R.C.P., and Sidney Russ, D.Sc. In addition to covering the field as did the German "Centralblatts," the editors of the various departments do not seem to be bound to local or national schools of medicine, but have consulted freely the periodical literature of all nations.
