Excerpt from The American Journal of the Medical Sciences, 1897, Vol. 113 The higher the mortality the more difficult is it to estimate in any disease the value of the various elements of prognosis. Pneumonia is certainly the most fatal of the acute infections of adults in temperate climates. No other disease kills from one-fourth to one-third of all persons attacked. Very elaborate statistics have been collected show ing the death-rate of the disease. These have been grouped together by Wells,1 of Chicago, in one of his excellent papers on pneumonia. Of cases the mortality was per cent. Unfortunately it is chiefly from hospitals that we have to gather our facts. S. H. Dickson, whose essay on Pneumonia is a storehouse of valuable information, comments on the remarkable equality of this proportional mortality in peace and all comfort, in hospitals of wealthy communities, in the field of destructive war, and in hospitals and barracks the emphatic seats of destitution, privation, exposure, and neglect.
