    It was originally intended to investigate the following grounds intensively once a year:I) The central portion of the'Dogger Bank, which is known to be a comparatively rich feeding ground and one on which transplanted plaice thrive and grow at an exceptional rate.2) The Leman Ground, which; at certain seasons, yields good catches of fish. -3) The Haaks area; which is representative of the Dutch young plaice grounds.Trawling, with a view to the investigation of the stomach contents of fishes, was also to be carried out on the same grounds and, as nearly as possible, at the same time. It was also hoped that time might be found for work with the Naturalists' dredge, Agassiz trawl & c., in order to gather data on the predatory fauna of the ground, it being unusual for such material to be taken in the bottom-sampler. Various events have, however, conspired to alter the programme and, with the exception of 57 stations worked near the Haaks Light Vessel and some few scattered stations in the different areas, the bottom sampling has been confined to the Dogger Bank, and it is to the results obtained on this ground that the present paper is devoted. Only a small amount of fish stomachs were collected, owing to lack of time, and this material has not yet been fully worked up. No systematic work has been done with any gear other than the Bottom Sampler and the Trawl.
