been looked upon with the greatest favor. There is here an 
old town at the mouth of Zuyder Zee, the naval stronghold of 
Holland, a station favorable for biological work on account of 
the rapid running current which renews the waters of the 
Zee. The station was founded by the support of the Zoological 
Society of the Netherlands, whose valuable work by the con- 
tributions of Hubrecht, Hoek and Horst, has long been known 
in connection with the development of the oyster industry of 
Holland. The work of the Society had formerly been carried 
on by means of a portable zoological station which the investi- 
gators caused to be transplanted to different points along the 
East Schelde, favorable on account of their nearness to the 
supplies of spawning oysters. The present station at the 
Helder is situated directly adjoining the great Dyke, a small 
stone building illustrated in the adjacent figure, two stories, 
surrounded by a small park. In itself the laboratory is a 
model one—the rooms are carefully finished and every arrange- 
ment has been made to secure working conveniences. A large 
vestibule leads directly into two laboratory rooms, and by a 
hallway communicates with the large, well-lighted library, 
and the rooms of the director. The aquarium room has, for 
convenience, been placed in a small adjacent building. The 
director of this station is Professor Hoek, and the President of 
the Society is Professor Hubrecht. Among others present at 
the opening of the building may be mentioned, van Bem- 
melen, Weber, Vosmaer, van Rees, Heinsius, Oudemans and 
Horst.
