ones are of glass. The experiment-basins in front of the buildings 

 were for the most part empty, since the Government supply was not

 27,806 marks from the German Fisheries Union. A detailed report

 Frenzel in the Zeitschrift fiir Fischerei, Heft I, 1895; separate copies 

 of it may be obtained. Of late, importance has been attached to 

 attracting young people, who come here from the Agricultural College 

 in Berlin, and from the University, and obtain an insight into the 

 fauna of the lake. 



The Biological Station on the Plonersee. 



"The Miiggelsee Station is undoubtedly a good beginning, and I 

 received the impression that Germany was ready to do much more 

 for the study of fresh-water biology, so soon as the results there 

 obtained should receive universal recognition. 



" The Plonersee lies in a delightfully picturesque district, reached 

 in about two hours from Liibeck, and on its shore, in the town of 

 Plon itself, is the biological station, where for the first time in 

 Germany the scientific investigation of fresh water found a decent 

 shelter. I was kindly received by the Director, Dr. Zacharias, and 

 in the short time at my disposal I obtained, through his guidance, an 

 idea of the arrangements of the station. The building contains a
