During the 1931 epidemic in New York City, Landon and Smith had the opportunity to study approximately 1,000 patients with poliomyelitis admitted to the Willard Parker Hospital. In addition they participated in an analytic survey of 1,400 cases distributed throughout other New York hospitals. There were 81 autopsies at the Willard Parker Hospital, and the study of the relationship between the symptoms, the methods of treatment and the pathologic observations is extremely valuable.
The chapter on diagnosis gives as clearcut a picture as possible of the preparalytic stage and discusses the variation in later symptoms depending on what part of the central nervous system is most extensively involved. The part on differential diagnosis gives brief, illustrative histories of cases. The generalized nature of the infection is well brought out in the chapters on histologic pathology and symptomatology.
The analysis of reports dealing with the use of serums is very instructive.
