Fig. 38 shows a piece of such coral brought up by the " Michael Sars " when fishing on the slope between the North Sea and the deep water of the Norwegian Sea. To avoid the corals we followed the advice given us and took a westerly course when we left Plymouth on the 9th of April, and from the outermost west- erly skerry, Bishop's Rock, we steered out over the coast banks to the conti- nental slope. Every- thingwas meanwhile got ready for trawl- ing and for the hydrographical and plankton observa- tions. Before leaving the coast bank we made observations at our first three stations in depths of 146, 149, and 184 metres, partly to test the winches and in- struments and partly to get a section of the waters on the bank. All our arrangements for hydrographical and pelagic work were found satisfactory. We secured a number of samples, and thoroughly tested the appliances. It was particularly important to see if the closing nets were to be relied on, so we lowered them to a depth of 50 metres, and closed them immediately. They came up empty,.
