THE Report of the Dove Marine Laboratory, Cullercoats, Northumberland, for the year ending June 30, 1932, has recently been published. The research during the year dealt chiefly with herring investigations, work on pollution, conditioned responses in fishes and hydrographical records. Large numbers of young herrings with three winter rings were present in the East Anglian October shoals. A new year class, that of 1928, has appeared in the winter shoals about the north of Scotland. It was not present in the samples from north-west Ireland. Mr. Storrow's work includes notes on organisms coming with the Atlantic waters during the last few years, the abnormal flow in all probability in fluencing the herring fishery, especially in the Clyde. His conclusions from the age composition of the Northumberland herring shoals are that the data support the idea of a gradual change in the fishing rather than change due to recent oceanic activity. Prof. Meek's work, with the help of Miss Benton, on Sagitta, shows that Sagitta setosa may be an important indicator of currents. Dr. Bull's researches on fish behaviour have been helped greatly by the erection of a partially sound-insulated and entirely separate building. Conditioning experiments involving the stimulus of small temperature increments and changes of direction of current flow are in progress and positive results have been obtained. In his work on the study of colour vision by the technique of differential inhibition, Dr. Bull has shown that the common shanny, Blennius pholis, has a wide range in wave-length discrimination, being able to distinguish one colour from another in many instances.
