but the latter gives a wider kn 
former, for it familiarizes one 
the animals. 
The laboratory at Roscoff not only permits a study at the work- 
table but also offers facilities for collecting. Excursions are made 
to grounds where certain animals occur and in that way the 
possibilities of knowing more of their mode of life are increased. 
This feature in the marine laboratories of Prof. Lacaze-Duthiers is 
certainly a most important one and one which particularly commends 
itself to a person whose sole knowledge of animals is based on 
specimens preserved in a museum or brought to him by a profes- 
sional collector. We may study the histology, or anatomy of an an- 
imal without knowing whether it lives in the sand or is free swim- 
ming, whether it is dredged or inhabits the shore line, but it is bet- 
ter to combine with that knowledge some familiarity with its natural 
habitat and its mode of life. One excellent feature in the Ros- 
coff laboratory and one which attracted me to it is the fact that it 
offers facilities for both kinds of work. 
There are two different departments in the laboratory at Roscoff', 
one for students who are beginners, the other for those who are 
investigators engaged in original research. These two depart- 
ments work harmoniously and the advantages are equal for both. 
The apparatus of a laboratory and the manner of investigation be- 
longs to the technique of zoological work, a consideration of which 
would take me too far into details for this article. There are many ex- 
cellent features in which this laboratory differs somewhat from those 
of other institutions of this kind, but in all marine laboratories with 
the readiness with which new methods are made public there is a sur- 
prising uniformity in technique in all marine stations. I should say 
that at Roscoff there is a proper regard to the relative importance 
of all branches of marine research, toxonomy, histology, anatomy 
and embryology, although perhaps the published results in the latter 
branch may show that it is not at present given the predominance 
that it has in some other similar institutions. 
An excellent feature in the laboratory at Roscoff is the existence 
of a small local collection identified for the use of investigators and 
students. For the information of those engaged in the study of 
animals found there a card catalogue with a notice of the time 
of collecting the genus, locality where it is found, the time of laying
