THE 



MARINE BIOLOGICAL STATION AT PORT ERIN 



BEING THE 



THIRTY-FOURTH ANNUAL REPORT 



DRAWN UP FOR THE 



OCEANOGRAPHY DEPARTMENT OF THE 



UNIVERSITY OF LIVERPOOL. 

 By Professor W. A. Herdman, C.B.E., F.R.S. 



The Port Erin Biological Station was transferred by the 

 Liverpool Marine Biology Committee to the University of 

 Liverpool on December 31st, 1919,* and from that date 

 became the marine laboratory of the department of 

 Oceanography. This change in responsibility and adminis- 

 tration has, however, caused no change in the scientific work 

 of the institution. Research workers and students are 

 admitted on the same terms as before, and the series of Annual 

 Reports and other publications will be issued in future by the 

 University in continuation of those produced by the Committee. 

 Professor James Johnstone, who is now (from October 1st, 1920) 

 the Head of the department of Oceanography, has asked me to 

 draw up the present Report, as the Port Erin establishment has 

 been under my direction during the greater part of the past 

 year. On account of this being a year of transition from the 

 old dispensation to the new, when no general investigations 

 of special note were undertaken, and also in order to effect 

 such economy as is possible in printing, I have decided to 

 report merely upon the usual statistics of the Biological 

 Station, along with short summaries of some of the researches 

 carried on by those working in the laboratory.
