TEANSACTIONS LIVERPOOL BIOLOGICAL SOCIETY. 



On account of the meeting of the British Association 

 in Australia in the summer of 1914, the yacht " B-una " 

 was not put in commission that autumn, and consequently 

 no samples were obtained outside Port Erin Bay at that 

 time. Nor have we any supplementary material this 

 year from any other parts of the district. As Mr. Riddell 

 has stated on an earlier page of this report, the Sea- 

 Fisheries steamer "James Fletcher" ceased to make her 

 periodic cruises after September, and the plankton 

 samples, although worked up, are not reported on, as they 

 form an incomplete series. They remain available, if it 

 seems desirable, for inclusion with those of the following 

 year. 



No change has been made in the nets employed, or 

 in the method of using them (see former reports). 



Plankton of Poet Erin Bay in 1914. 



As before, the plan of work within the Bay has been 

 to take two horizontal hauls (coarse and fine nets) and 

 one vertical haul twice each week throughout the year — 

 that is, about 24 hauls per month. The twelve months 

 of 1914 are represented by these hauls as follows: —

A glance shows that only in one month (November) 

 has weather interfered much with the work. As a rule 

 the collections were made with regularity, and the 

 monthly average is high. We are much indebted to 

 Mr. Cregeen, of the Biological Station, for his successful 

 endeavours to keep us supplied with the necessary 

 statistical data.
