CONTRIBUTIONS OF ZOOLOGY TO 
HUMAN WELFARE! 
My colleagues in this symposium have 
emphasized the important contributions 
to human welfare which have come from 
zoological research and the application of 
the resulting discoveries. On the contrary, 
I shall tend to stress the contributions which 
biology, and in particular zoology, may 
make through education which aims to ex- 
tend scientific knowledge to everybody. 
Moreover, my colleagues have chosen to 
speak concerning the contributions of zool- 
ogy to human welfare in lines which are 
directly useful with reference to the phys- 
ical well-being of the human race. Hence 
they have emphasized the practical bear- 
ings of zoological science in its applica- 
tions to the production of useful animals 
and plants and in the relations of certain 
animals to human health. In short, a strong 
ease has been made for zoology as a science 
which has immensely important contribu- 
tions to the economic and hygienic welfare 
of the human race. With all this emphasis 
on zoology in its direct material or physical 
bearings on human life, I most heartily 
agree. As a matter of education, I be- 
lieve in ‘‘applied zoology’’ which stresses 
the science of animals as they economically 
or hygienically affect. mankind; but I re- 
gard zoology limited to its direct material 
usefulness, to its contributions to physical 
human welfare, as failing to develop the 
possibilities of the science as it may affect 
racial welfare and intellectual welfare. 
Hence, I have devoted my paper to zool-
