Laboratory.” It is situated on the English Channel and col¬ 
lecting opportunities are most excellent here for there is a maxi¬ 
mum difference of twelve meters between tide levels. The sta¬ 
tion is an annex of the Sorbonne. The buildings are located on 
a large plat of ground containing some 6,000 square meters and 
partially enclosed by a large, beautiful garden which contains 
many exotic plants, some of which are sub-tropical, this being 
made possible by the very mild climate. 
The aquarium extends parallel with the shore line and is 
thirty meters long by ten wide. In the middle there are two 
large granite basins and along the walls of the two sides there 
are forty aquarium tanks. Between the aquarium and the sea, 
there is a large vivier , a basin which is used both for experi¬ 
mental work and to retain a supply of Water for the laboratory. 
A large addition to the laboratory was built in 1907 and 1908 
which increased the work places to more than three times the 
original number. Formerly there were only twelve rooms for 
investigators but this number was increased to thirty-seven. 
Besides these, there is a general laboratory containing twelve 
work places and this number can be increased to eighteen if 
necessary. One room is reserved for the study of animal psychol¬ 
ogy, another for library, two for dark rooms, and one for physi¬ 
cal and chemical investigations. There are also sixteen living 
rooms which are at the disposal of students and investigators 
for a very nominal rental. 
The twenty-five investigators’ rooms that have recently been 
added are available for both foreign and French states, univer¬ 
sities, and biological societies for an annual rental of 1,500 
francs. It is the purpose of the present director, Dr. Y. 
Delage, to make the station international in character. Ac¬ 
cordingly the stranger is given every privilege accorded the 
French biologist, that is, a table, reagents, microscope and other 
apparatus, as well as material, all gratis. It is open to investi¬ 
gators from April 1 to September 30. There are two Summer 
sessions during which students are admitted. The first extends 
from July 15 to August 15 and the second from August 15 to 
September 15. The station possesses a collecting sloop twenty
