This book contains the proceedings of the conference on Gout and Purine Metabolism held in October 1964. Originally published as a supplement to Arthritis and Rheumatism, it is now being offered in hardback form. All of the recognized authorities have contributed, and a great deal of data has been collected in one place. It must be recognized, however, that the data is at least three to four years old now, a serious consideration in evaluating a book dealing with a field that is practically exploding with new knowledge. For those expressly interested in period photographs for historical purposes, the book may serve as a sight-seeing postcard packet from 1964—and will be opened just about as often.
