Portions of this work have been read before the Royal Society and the Royal Physical Society, Edinburgh as well as at the meetings of the British Association at Oxford, Manchester, and Cambridge. The author believes he has satisfactorily solved the hitherto disputed questions as to food, periodical visits, migration, He has also, for the first time, established the important fact, that herrings Visit our coasts twice in the year, — that, in fact, there is a winter and a summer herring periodically arriving on the different coasts; and already, from this knowledge, additional supplies have been obtained where no previous fishery existed.
