 waters shows how much laborious work has been done which 

 is not now published, but which will be of value some day 

 when we are able to lay it in detail before the Committee. 



Plankton Investigation. 



Although work out at sea is wholly stopped, the periodic 

 collection of plankton samples in Port Erin Bay, at the South 

 end of the Isle of Man, is one portion of our usual work which 

 it has been possible to continue without alteration. During 

 two important periods of the year, spring (April) and autumn 

 (August and September), I have been able to take very frequent 

 samples from my motor boat, and during the remainder of the 

 year the staff of the Biological Station have collected and 

 preserved periodic gatherings. These have been microscopically 

 examined by Mr. Andrew Scott, at Piel, the results have been 

 reduced to tables and diagrammatic curves by Miss Lewis 

 at Liverpool, and we give a summary of the results in a short 

 article further on in the Eeport. 



Minor Local Fisheries. 



I have thought it justifiable to reprint* at the end of 

 this Report a short address on " The Exploitation of Inshore 

 Fisheries," which was read before the British Association 

 at the Newcastle-on-Tyne Meeting, last September. It formed 

 the opening of a day's discussion on the subject of Inshore
