Work at the Piel Laboratory. 



Mr. Scott makes the usual report as to the fishermen's 

 classes, the visitors, the fish-hatching operations, and other 

 matters relative to work at our Piel Laboratory and Hatchery 

 in the Barrow Channel. The defensive operations in that 

 neighbourhood necessitated by the outbreak of war restricted 

 the work greatly in many directions. The usual fish-hatching 

 operations were carried on in the spring of 1914, but, for various 

 reasons, these will be impossible in the season of 1915. 

 The practical classes for fishermen are, however, being 

 carried on with some modifications. Increased attention is 

 being given to the preparation of trawl fishermen for the 

 Examinations of the Board of Trade. Mr. Scott's analysis of 

 the whitebait samples, and his work on the fish- eggs and on 

 the plankton of the Irish Sea were also carried out at the 

 Piel Laboratory. 



Work at the Liverpool Laboratory. 



Diseases of Fishes. 



Dr. Johnstone reports at length on several fishes which 

 had been condemned as unfit for human food by Port Sanitary 

 Officers and were sent on to the Laboratory for confirmatory 

 evidence of the desirability of condemnation. The specimens 

 received during 1914 illustrate very well some extreme cases 

 of cancerous growths in valuable edible fishes and are worthy 

 of a detailed report. Some other cases of obscure disease in 

 fishes closely analogous to well-known human diseases are 

 also described and illustrated. 



Bacteriological Investkj ations. 



Dr. Johnstone makes a lengthy report on investigations 

 carried on partly at the Liverpool Laboratory, and partly at 

 Piel and in the open, with respect to the best methods of
