This is the age of symposiums, conferences and panels, and, according to the preface, "This volume contains the papers presented at a symposium in St. Louis, March 24th and 25th, 1944, under the joint sponsorship of the Research Unit of the St. Louis City Infirmary and the Washington University School of Medicine."
The papers all deal with some phase of the process of aging, but they make no claim to a systematic coverage of the subject, nor do they show any particular correlation. Some are reflective and semiphilosophic— meditations, if you will, de senectute; others report concrete results of experimental work, such as the interesting contribution of Saxton on nutrition and growth and their influence on longevity in rats. The volume is well printed and illustrated. There is no index.
