    8 SUMMARY AND GENERAL REPORT. Circumstances did not permit of making trawling experiments later than August 27th. The four trials which were made up to this time proved interesting, however, since they furnished the necessary evidence of the return of the flat fish to the inshore waters in the summer. In addition the “ Evadne,” by means of a small net in December and March, on the sandy ground to the north of the mouth of the Tyne, disclosed the presence of young gadoids, gobies, and small herrings, and sprats — practically “ white-bait.” Mr. Sisson adds notes to this account on the salinity of the water obtained at the trawling experiments, and off Cullercoats, and on the question of the effect of freezing on the salinity of sea water. Further particulars are given with reference to the migrations of turbot and plaice. A turbot liberated in August, 1907, at Skate Roads was captured in July, 1909, 48 miles E.£S. of Aberdeen. A plaice marked in Skate Roads in July, 1909, was caught in December, 1909, near the Bell Rock. In addition to the further evidence of the growth of plaice furnished by the results of this experiment, an account is given of the growth of the plaice in one of the tanks of the aquarium.
