AT ITS ANNUAL MEETING in 1957, the Royal Society of Canada, celebrating the seventy-fifth anniversary of its foundation, departed from the accustomed pattern of its meetings. Instead of assembling in separate sections, Fellows from each Section of the Society were asked to contribute to a conspectus, focused by their specialized knowledge and trained discrimination, to reveal to the Society and to others certain trends and tendencies in Canada. Subjects and contributors are: "These Seventy-Five Years" (Presidential Address by W. A. Mackintosh); "The Roles of the Scientist and the Scholar in Canada's Future" (W. A. Mackintosh, David L. Thomson); "The Penalties of Ignorance of Man's Biological Dependence" (E. G. D. Murray, K. W. Neatby, I. McT. Cowan, G. H. Ettinger, R. H. Manske); "The Social Impact of Modern Technology" (N. A. M. MacKenzie, V. W. Bladen, E. W. R. Steacie, W. H. Watson); "Our Economic Potential in the Light of Science" (H. C. Gunning, J. E. Hawley, L. M. Pidgeon, B. S. Keirstead, Maurice Lamontagne); "Human Values and the Evolution of Society" (G.-H. Lévesque, T. W. M. Cameron, A. S. P. Woodhouse, R. Elie, Roy Daniells); "Let Us Look to Our Human Resources" (F. H. Underhill, J. K. W. Ferguson, L.-P. Dugal, W. B. Lewis). The volume is further prefaced by the address given by His Excellency the Right Honourable Vicent Massey, Governor-General of Canada, "The Weighing of Ayre."
