Juday—Some European Biological Stations. 1265 
Holland. 
In 1890 a zoological station was founded at Helder, in the 
province of Horth Holland, through the influence and support of 
the Zoological Society of Holland. It has been maintained 
regularly by this Society, hut at present the government pays 
an annual rental for one floor which is used as the laboratory 
for the Hollandish biologists engaged in the International Horth 
sea investigations. The building is three stories high, the first 
and second floors being occupied by laboratories, a museum, and 
a library, and the third serving as a residence for the director, 
Dr. Bedeke. 
The chief aim of the station is to furnish accommodations for 
research work to the members of the Zoological Society. There 
are tables also for half a dozen students or young investigators, 
but such individuals must either first become members of the 
society or must be vouched for by a member. The laboratory 
is located on one of the mouths of the Zuyder Zee so that it has 
the advantage of both the Horth sea and the Zuyder Zee for 
collecting purposes. Helder itself is a very interesting city. 
It is the chief naval station of Holland and is also noted for its 
huge and extensive dykes. 
Belgium. 
The Station Biologique d’Overmeire is an annex of the Ha- 
tural History Museum of Belgium. It is located on the lake 
of Overmeire not far from Brussels. The laboratory was 
opened in April, 1907, and it occupies a large residence on the 
shore of the lake which is known as Chalet Prince Albert. 
There are five rooms, three of which are used as laboratories, 
one for the small but well selected and growing library, and 
one for a museum containing a collection of local fauna. The 
basement is fitted up with aquaria and a dark room for photo¬ 
graphic work. For such a young station it is very well 
equipped with collecting and laboratory apparatus. 
The lake on which the station is located, lies in a low, flat, 
level country, and it is in fact an old abandoned bed of the 
Scheldt river. It has an area of 85 hectares and a maximum
