24 NOMENCLATURE 
But, such as it is, it has been reached by this 
system of comparison, which, though I speak 
of it now in its application to.the study of Nat- 
ural History, is equally important in every other 
branch of knowledge. By the same process the 
most mature results of scientific research in 
Philology, in Ethnology, and in Physical Sci- 
ence are reached. And let me say that the 
community should foster the purely intellect- 
ual efforts of scientifie men as carefully as 
they do their elementary schools and _ their 
practical institutions, generally considered so 
much more useful and important to the public. 
For from what other source shall we derive the 
higher results that are gradually woven into the 
practical resources of our life, except from the 
researches of those very men who study science, 
not for its uses, but for its truth? It is this that 
gives it its noblest interest: it must be for truth’s 
sake, and not even for the sake of its usefulness 
to humanity, that the scientific man studies Na- 
ture. The application of science to the useful 
arts requires other abilities, other qualities, other 
tools than his ; and therefore I say that the man 
of science who follows his studies into their 
practical application is false to his calling. The 
practical man stands ever ready to take up the 
work where the scientific man leaves it, and to 
adapt it to the material wants and uses of daily 
life.
