THE Marine Biological Association has now at Plymouth a laboratory in the same class as those at Naples and Woods Hole. It only lacks that cosmopolitan element, which largely makes the charm at Naples. It has its zoological, physiological, and fisheries departments and a research vessel that can visit even deep-sea areas. Its growth, while largely due to the recognition of the importance of basal scientific research work in the elucidation of practical problems by the Development Commissioners, is chiefly owing to the broadness and scientific insight of its Director, Dr. E. J. Allen, this being the main factor in attracting the fifty-six naturalists who occupied its tables in the past year; Dr. Bidder has also been generous and, as treasurer, active in obtaining money for several new buildings.
