FRESHWATER BIOLOGICAL STATION, WINDERMERE. 



Report of Committee appointed to aid competent investigators selected by the 

 Committee to carry out definite pieces of work at the Freshwater Bio- 

 logical Station, Wray Castle, Windermere (Prof. F. E. Fritsch, 

 F.R.S., Chairman ; Prof. P. A. Buxton, Secretary ; Miss P. M. 

 Jenkin, Dr. C. H. O'Donoghue (from Section D) ; Dr. W. H. 

 Pearsall (from Section K) ). 



The British Association table has been occupied by Mr. R. Misra (Univer- 

 sity of Leeds) and Dr. M. Rosenberg. The former has carried out ecolo- 

 gical investigations on the higher aquatic plants (principally Potamogeton) 

 and has studied the chemical features of the muds on which they grow. 

 Dr. Rosenberg has continued pure culture work with a number of desmids 

 and other algae and has commenced investigations under natural conditions 

 on the plankton algae in Windermere and in the streams which feed it. It 

 is anticipated that these investigations, if carried out throughout the year, 

 may afford much information on the origin and causes of temporary 

 abundance of plankton algae and that they may be as fruitful as similar work 

 already carried out in the sea.
