in the direction of how best to keep young fish alive at a 
moderate cost, till they attain a fair size. At present 
practical difficulties in feeding, and possibly in connection 
with the movements of the water, block the way, but 
Mr. H. Dannevig at the Hatchery of the Fishery Board 
for Scotland has had some success with the Plaice, and 
MM. Fabre-Domergue and Biétrix at Concarneau with 
the Sole, and we can scarcely doubt that further investi- 
gation and experience will show us the best methods to 
pursue. It is at institutions like ours, where scientific 
work is combined with the hatching, that experiments in 
feeding and aeration can be carried out which will 
eventually lead us to the successful rearing of the young 
fish that we now hatch and distribute as fry. The rearing 
of young Soles at Concarneau from the egg to a size of 
35 mm., with a loss of only 50 per cent., is a striking and 
encouraging fact. 
The laboratory at Piel has been occupied by several 
scientific workers during the year. In addition to Mr. 
Seott, who has worked there throughout the year, Mr. 
Johnstone has paid several visits, and Mr. Cole, from 
University College, Liverpool, spent the greater part of 
September at Piel working at the anatomy of the Plaice. 
Dr. H. Lyster Jameson, from the Municipal Technical 
College at Derby, worked in the laboratory for short periods 
during the summer, carrying out some investigations con- 
nected with the formation of pearls in marine shell-fish. 
Mr. H. C. Chadwick, Curator of the Port Erin Biological 
Station, spent a couple of weeks in March studying the 
methods of sea-fish hatching. 
Amongst the numerous visitors who came to see the ex- 
hibition and the work going on in the establishment during 
the year were the following :—
