ON May 20–22 the Royal Society of Canada met at the University of Toronto. During the evening of May 20 Dr. Charles Camsell, Deputy Minister of Mines, gave his presidential address, entitled “Canada's Position in the Mineral Situation of the British Empire”. Dr. Camsell, while emphasising the fact that no nation is independent of others in the matter of mineral supply, pointed out that, mainly owing to the diversity and amount of Canada's mineral production, the British Empire approaches much more nearly to a self-supporting basis than any other political unit. At the same meeting, the Flavelle medal was awarded to Dr. F. G. Banting, for his pioneer research on insulin; the Lome Pierce medal to Adjutor Rivard, for outstanding contributions to literature, and the Tyrrel medal to Dr. Lawrence J. Burpee, for valuable historical work. The customary popular lecture was this year given by Dr. J. S. Plaskett, Director of the Victoria Observatory, on the “Structure and Motions of the Galaxy”. A novel feature of the meeting was a series of radio talks by the presidents of the various sections, which were broadcast over the Dominion.
