THE report of the Principal on the work of the University of London during 1940–41 is distressing testimony to the wanton destructiveness of modern warfare. The wisdom of the policy of dispersal, which at one time aroused criticism, has been fully borne out by the widespread damage that many of the University buildings have sustained from air raids. This damage has already been described in NATURE. The teaching staff of the University has lost the services of eighty–six professors and readers, who together with many other teachers are now engaged in various forms of war work. Owing to the claims of national service the roll of internal students in the second year of war is expected to show a fall of about 40 per cent. Nevertheless, in spite of all difficulties, the essential work of the University has been carried on in a most remarkable manner. Except for certain readjustments necessitated by war conditions, no significant changes have been made in.the curriculum, and examination standards have been fully maintained.
