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.
