THE tragic death of Douglas Raitt as the result of a motor accident on October 4, 1944, at the early age of forty-one, will be deeply regretted not only by marine biologists but also by the general public, for apart from his scientific attainments, he had wide cultural interests and was recognized as a successful broadcaster and as a composer of Scottish songs. In particular, fishery research has lost a most promising worker, who had a brilliant career before him.
