Juday—Some European Biological Stations. 1273 
day. There are laboratory and living accommodations for ten 
persons. 
Formerly the station served as a supply depot for the Berlin 
Aquarium but recently this Aquarium was abandoned. Its 
chief source of income at present is a subsidy from the Prussian 
government. Dr. Hermes is its director. Rovigno itself is an 
old city of about 10,000 inhabitants, chiefly Italian speaking. 
The large number of narrow, crooked streets and quaint build¬ 
ings make the city an interesting place to visit. 
In 1905 through the munificence of Dr. C. Kupelwieser of 
Vienna, a Biological Station was established on some lakes near 
Lunz, Lower Austria, by Dr. R. Woltereck of the University of 
Leipzig. Dr. Kupelwieser owns a large game preserve here, in 
fact practically an entire mountain valley in which there are 
three lakes. His large summer residence, the Seehof, stands 
near one of the lakes, and one wing of this castle has been con¬ 
verted into a pleasant, and well appointed laboratory. Two 
basement rooms contain aquaria which are supplied with an 
abundance of running water. One contains large cement 
aquaria for fish-breeding experiments, and the other has glass 
aquaria of various sizes. 
On the ground floor are located the library room with a well 
selected and rapidly growing library, a general laboratory, two 
rooms with tables for research work, the director’s room, a store 
room for apparatus and supplies, and a dark room fitted up for 
photographic and physiological work. Above the laboratory, 
there are several living rooms for the accommodation of students 
and investigators. 
Hot far from the Seehof is the “Dependance” of the station 
which contains living rooms for the assistants, a heating plant, 
and two glass culture houses. These glass houses contain cement 
and glass aquaria of various sizes. One, the Warmhaus, is fitted 
with steam heating apparatus for experimental work at high 
temperatures, the cement aquaria themselves being supplied with 
steam pipes. The other, the Kalthaus, is supplied with run¬ 
ning water from a cold spring so that experimental work may 
be carried on at tolerably low temperatures. By means of these 
two houses, experiments may be carried on at temperatures vary-
