microphysiology for the student of biology in the widest sense of the 
word. To study phylogenetic development from structures only is 
to study results without causes. The important study of relations is 
a study of animal life. The whole field of economic zoólogy asks for 
better knowledge of outdoor zoólogy. In a word,the recent path 
of zoölogical investigation has been fo go back to the methods of 
our great master, Charles Darwin, and use as an aid our detailed 
microscopical study which has absorbed almost the entire time of 
the zoölogist for years. 
If these are true interpretations we must hail every new oppor- 
tunity given the student of zoólogy in any part of the world to study 
animals in their natural surroundings, and on a scientific basis. 
Especially is such the case when we are hoping to get a biological 
station in Greenland where the conditions and fauna are so different 
from those of any place where similar stations are found. The stu- 
dent of variation will then have an opportunity of transferring ani- 
mals from one extreme climate to another. A thorough knowledge 
of how the fauna is adapted tothe surroundings in a land where the 
sun never sets for three months and never is seen for a still longer 
period of thé year will surely yield some interesting results. 
All the great groups of invertebrates, and vertebrates with the 
exception of the amphibians and reptiles, are represented in Green- 
land. The flora is surprisingly large so there is no lack of oppor- 
tunities for study as soon as a well equipped laboratory is established 
there. According to the estimate of Mr. Porsild the trip from Cop- 
enhagen and return and one year's study in Greenland would, under 
those conditions, be reduced to one third of the present expense or 
to $375. ; 
T economic importance of such a station I have had various 
opportunities to show, and I need not point them out here but enough 
to say that Denmark ought to learn from the United States to protect 
her industries of hunting and fishing, and this can only be done in : 
haee: by having competent people there to protect these indus- 
es. 
It iun be hoped that the government of Denmark will do its 
share in furthering the study of biology by offering the small sum of 
MAU rea reg for such a station which will be of great value 
ntific and an economic point of view.
