and cockles — of various fluids, such as fresh-water,

 way to the shellfish beds. 

 (4) I should propose that early next spring, as soon as 

 the Sea-Fisheries steamer is able to obtain for us 

 the necessary spawning fish, Mr. Scott should try, 

 in the Piel laboratory, the same experiments in the 

 hatching of edible sea-fish which were successfully 

 carried out last Easter at Port Erin." 



Since this memorandum was prepared, however, a wider 

 scheme has developed involving the conversion of the 

 villa itself into a Marine Laboratory both for Fisheries 

 Observations and Scientific Eesearch. As the details of 

 that scheme are now under consideration it would be 

 premature to discuss them in the present report. I have 

 no doubt that the results of the work carried on at the 

 Piel Marine Laboratory will figure largely in our future 

 reports, and will have an important influence on the 

 scientific development of the Lancashire Sea-Fisheries.
