A symposium on infantile paralysis was delivered in April 1941 at Vanderbilt University under the auspices of the National Foundation for Infantile Paralysis, Inc. There were six lectures. These were collected and bound in book form, making a volume of 239 pages with 575 references and an excellent cross index. The history, etiology, immunology and serology, pathology and pathogenesis, epidemiology and treatment are considered, including the latest available information on each subject. Some of the lectures are particularly distinctive, both for the information and for the excellent English. It is unfortunate, however, that clinical evidence as to pathogenesis and diagnosis is omitted.
