ried on here by various Swedish investigators. The main build' 
ing was erected rather recently, having been begun in the fall 
of 1903. It is two stories high. The first door is occupied 
by a large public aquarium, three laboratory rooms, and a con¬ 
servation room; the second has a stock room, four work rooms, 
and the library. The station possesses a fair sized collecting 
boat, the Sven Loven. 
In 1903 a station was established at Vassijaure, under the 
direction of the Royal Academy of Science of Stockholm. It is 
situated in Lapland, in northernmost Sweden, well within the 
arctic circle, and is near the northern limit of trees. The labor¬ 
atory is near lake Vassijaure and is also only about 21 kilo¬ 
meters from the very large lake Tornetrask. The station pos¬ 
sesses little in the Way of apparatus except meteorological in¬ 
struments. The building serves as laboratory and dwelling 
place for investigators. It was established for general scien¬ 
tific work but it is frequented most by biologists. 
A second fresh-water station has just been built on some lakes 
in southern Sweden. Six tables are available for investigators. 
It is the aim of this laboratory to give special attention to the 
biology of fishes. 
Denmark. 
The modest laboratory of the Danish fresh-water station con¬ 
sists of the deck house of the ship used for the Ingolf Expedi¬ 
tion. It was brought to Euresee in 1898 and converted into 
the present laboratory. The station is equipped with a good 
motor boat, plankton nets, and various other kinds of collecting 
apparatus. It is most favorably situated, being located in a 
district where several lakes which possess very different physical 
and biological characters, may be easily reached from the labor¬ 
atory. As a result of the investigations of Dr. Wesenberg- 
Lund, director of the station, the knowledge of the biology of 
these lakes has grown from almost nothing at the time the labor¬ 
atory was established until they now may be classed among the 
most thoroughly studied lakes in the world. Two very im¬ 
portant volumes relating to the work of the laboratory have been 
published as well as many shorter articles. In 1906 the station 
Was annexed to the University of Copenhagen.
