I subjoin the results of statistical inquiries into this question, continued from the point at which they were left in the last number of this Journal. Having been permitted by the Council of the Association to undertake a series of lectures along the coast of Yorkshire on behalf of the North-eastern Sea Fisheries Committee during the present autumn and winter, I find it necessary to restrict the present paper to the smallest possible compass, reserving practically everything except the mere statement of figures until more time shall be available for the deduction of results.

I regret to have to say that the statistics for the month of May are by no means complete. Bibliographical work in connection with several scientific papers on which I was then engaged necessitated my absence from Grimsby during the early part of the month, and the sudden illness of my subordinate during the same period interfered with the arrangements I had made for keeping up the records. The statistics as to plaice are, therefore, a blank for the first week of May; Mr. Clark unfortunately remained unwell for the rest of the month, while a serious break-down in the circulating apparatus of the Cleethorpes aquarium made great demands upon the time which I should otherwise have been able to devote to market observations; and, though I was able to keep account of all plaice landed, my statistics as to haddock and cod are too meagre to be worth insertion.
