The table shows that seven of the marked plaice have been 
accounted for, and that with one exception they remained on practi- 
cally the same ground as that on which they were liberated. Three 
of the four which were liberated at Blyth Bay and recaptured had 
moved a slight distance to the south, and the same may be said of 
the Creswell specimen. But the one which was recaptured at St. 
Andrews is very interesting, in that' it had travelled across the 
mouth of the Forth from Goswick Bay, a distance in a straight line 
of 42 miles. 
It would not be right to draw any inference from this solitary 
example, and we are the more unwilling to do it in thfs case for 
the fish was captured in Skate Roads, and liberated at Goswick 
Bay. But we may be excused for saying that it is certainly remark- 
able that in the case of both the experiments on migration we have 
conducted during the year, we have had to record a movement to 
the north. It would indeed be important if such investigations 
were to show that in our region there was a general migration in 
this direction to compensate so to speak in some degree at least for 
the southward movement of the ova and fry. 
It is worthy of note, moreover, that although we sometimes 
caught again on the same day at the same place a few of the plaice 
we had just liberated, we did not catcli any of the marked fishes 
when the same station was subsequently visited.
