and fish-culture work. The station is conducted under the aus¬ 
pices of the German Fishery Association. 
Important plankton investigations have also been made on the 
Elbe river in the vicinity of Hamburg. This Work has been 
carried on by Dr. Richard Volk under the auspices of the Ham¬ 
burg Hatural History Museum. The plankton has been studied 
both qualitatively and quantitatively and chemical analyses of. 
some of the Crustacea have been made to determine their value 
as fish food. 
Switzerland. 
Strictly speaking there is no regular biological station on any 
of the Swiss lakes, yet the biologists of this country have been 
among the leaders in limnological work for many years. The 
classic work of Forel on lake Geneva has served as a model for 
very much of the work that has been done since its appearance. 
In 1887 a Limnological Commission was organized as a de¬ 
partment of the Swiss Natural History Society and this commis¬ 
sion drew up a comprehensive program for physical, chemical, 
meteorological, and biological studies on the lakes. As a result 
the various lines of work have been well co-ordinated and uni¬ 
fied. Thorough and systematic studies have been made on four 
lakes for a number of years and some of the results have been 
published from time to time. Also Professor Zschokke of the 
University of Basel has devoted a number -of years to a thorough 
and comprehensive study of the fauna of the typical Alpine 
lakes. 
France. 
The extended coast line of France offers some splendid oppor¬ 
tunities for marine stations and the biologists of that country 
have availed themselves of some of these advantages by estab¬ 
lishing a number of laboratories. Most of the stations are affili¬ 
ated with universities and receive government aid but some 
have been founded by local scientific societies. Two, are spe¬ 
cially concerned with practical problems relating to the fisheries. 
The largest and most important French station is the one that 
was founded by de Lacaze-Duthiers at Roscoff in ,1872. Since 
the death of its founder it has been named the “Lacaze-Duthiers
