The Biological Station on the Plunersee. 



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

 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
