Speaking generally, the results are similar to those 
of former years. A certain small proportion of plaice 
have migrated (apparently for good) out from the isastern 
part of the Irish Sea. ‘Two of these instances are 
interesting. Plaice No. LL857 was recaptured off Water- 
ford by the Ostend steam trawler “ Jules Henri,” O 115; 
and Plaice No. LL944 was retaken in N. Lat. 49° 80’, 
W. Long. 8° that is, out from the mouth of the Enghsh 
Channel, by the Fleetwood steam trawler * Mulalia.” 
I may refer briefly to the results of Iixperiment 1 of 
1908. It will be seen that, with one exception, the fishes 
returned have been recaptured in close proximity to the 
place of liberation, and mostly within two months after 
the date of the experiment. he latest date on which 
one of these fishes was recaptured in the Barrow area 
was 30th August, 1908. One fish has been returned since 
then, viz., LL962, recaptured near Bahama Bank Light 
Ship. When we made this experiment we expected that 
a considerable proportion of the marked plaice would be 
recaptured during April, May and June, but that, after 
the latter month, the migration seawards would begin, 
and that some of the larger fishes would be retaken on the 
grounds lying between the Morecambe Bay and Liverpool 
North-West Light Ships, during the summer; and in the 
Bahama Bank area, during the late autumn and winter. 
Now, none of these fishes has been taken on the former 
area, and only one on the latter area. This fish is the 
latest, belonging to the experiment, that has been returned 
up to the time of writing this report (December, 1908). 
The interpretation of these facts seems to be that the
