This third volume maintains the same high standards of the two previous volumes. The earlier volumes dealt with general aspects and aging in transient tissues. In the current book, 12 subjects are reviewed by experienced investigators, and a summary of their personal researches is given. Each chapter includes an account of the discussion that followed the presentation of the paper. As those present, limited to 28, were persons with long experience in research in gerontology, the report may be accepted as the best current thought on the subjects presented. Much credit for the substance of this work is due Dr. Charles H. Best, of Toronto, who was the chairman, and to Dr. R. E. Tunbridge, of Leeds, England, who was a consultant.
The subjects, obviously selective, included: The Biological Approach in the Comparative Study of Ageing by Alex Comfort; The Study of the Ageing of Cells by J. F. Danielli;
