My purpose in this study was to investigate the immediate cause of death in pneumonia, both from a clinical and from an anatomic standpoint. The material consists of 200 consecutive cases of pneumonia, which were studied clinically and which finally came to autopsy in the Fourth Medical Service at Bellevue Hospital.
The autopsies were performed by various members of the pathologic staff under the chief pathologist, who has permitted me to utilize the material in this manner. The clinical studies were based on the usual records of the cases under the regular attending physicians and their associates of the division, with additional notes when possible of the immediate manner of death.
