PROF. ERIC ASHBY, who has been appointed to succeed Prof. Drummond, was educated at the City of London School and at the Imperial College of Science and Technology, where he was Forbes medallist. As a Commonwealth Fellow he worked at Chicago, the Desert Laboratory at Tucson and at Hawaii. In 1931 he was appointed lecturer at the Imperial College, and in 1935 he went to Bristol first as lecturer and later as reader in botany. In 1938 he was appointed to the chair of botany at the University of Sydney. Almost throughout his time in Australia he has been fully engaged in the organisation of scientific work in connexion with the War and, during the past year, he has been in the U.S.S.R. on a scientificiliaison mission (Nature, 155, 72 ; 1945). In his research work a strong mathematical bias led him to apply, with success, statistical methods to the problems of ecology ; but he has been chiefly concerned with the physiology and genetics of the processes of growth and development. Early work produced elegant studies on the growth of Lemna under controlled conditions. Later he made original contributions to our knowledge of the mechanism of hybrid vigour. A man of great energy and of incisive and original mind he has a most stimulating influence on his friends and students. He will bring to his new post the experience of wide travel and generous sympathies. His return to Britain will notably strengthen botanical teaching and research in this country.
