.the very important limnological work that has been in progress 
for some years and is still being carried on here, mnst be men¬ 
tioned in this connection. Several valuable papers dealing with 
the physical, chemical, and biological phases of these investiga¬ 
tions have already been published. Much of the work has been 
done under the direction of Dr. von Loczy, who is president of 
the commission. 
Although the laboratory in the “Vivarium 1 ’ which is located 
iii the Prater at Vienna is purely for experimental researches 
and not for limnological work, it is well worth mentioning here. 
The one story building stands in a large court near the center 
of the park. It is a large structure and has a number of rooms, 
some of which are designed for special investigations and others 
for laboratories. Among the former may be mentioned two 
glass houses, a room fitted with special heating apparatus for ex¬ 
perimental work on tropical animals, some rooms with large 
cement aquaria for work on fishes, and an underground dark 
room for cave experiments. Then there are chemical, physio¬ 
logical, botanical, and zoological laboratories. Dr. L. von 
Artheim, director of the Laboratory, has charge of the botanical 
researches and Dr. Przibram has charge of the zoological work.

of the conveniences, equipment, and material that are here acces¬ 
sible to every investigator. Even a brief visit suffices to explain 
why this station has become the mecca of biologists in every 
quarter of the globe. The three attractive stone buildings are 
situated in one of the city parks, the Villa Nazionale, and are 
surrounded by a wealth of semi-tropical vegetation. They are 
separated from the blue water of the Gulf of Naples only by a

The station was founded in T874 by the late Dr. Anton Dohrn 
whose son is now its director. As a result of the founder’s 
efforts and careful management, it has enjoyed a phenomenal
