In 1915 we presented1 the results of study of 200 deaths in coma, with special reference to the clinical diagnosis of uremia. During the past year we have been able to review the clinical records of an additional 200 persons dying in semiconsciousness or coma and, as in the first series, one of us (E. R. L.) has examined all the bodies. In grouping these 400 deaths in coma, the possibility of aiding diagnosis of the various forms of coma, particularly in the practice of large hospitals receiving a great deal of so-called emergency work, has been kept in mind. We further believe that a presentation of the diagnosis efficiency of clinicians in the Cook County Hospital, and especially the improvement since the first report, will compare, favorably with similar statistics from other large hospitals admitting many persons in some degree of coma.
As in our first consideration, we think the conditions are best represented by charts which take
