view is always that of the pursuit of the science for its own 
sake, so that as many as may be needed may find places as 
teachers of the subject. For all these lines of endeavor the 
same general kind of training appears to be requisite, as has 
been pointed out. Such training must aim to make the stu- 
dent familiar with the great principles of the science, with 
some of the methods employed, and with enough of the lit- 
erature so that he may make efficient use of the libraries in 
his future work. Above all, he must be led to a facile and 
versatile attitude of mind, which regards his science as a con- 
tinuously changing thing, with new needs arising at every 
turn of its progress; also, he must be not over-timid in fol- 
lowing his problem wherever it may lead, even into the fields 
of other sciences. 
Tue Work so FAR ACCOMPLISHED OR IN PROGRESS 
The accomplishment of a scientific research laboratory 
should be calculated as the sum of two different terms. The 
first of these is, obviously, the progress actually made in in- 
vestigation, in the solving of problems, and in contributions 
toward what we name the general fund of human knowledge. 
The component parts of this term are usually easy of descrip- 
tive statement, but difficult of comparative evaluation. The 
second term includes what is commonly thought of in uni- 
versities as the training of students, but it should also in- 
clude the intellectual progress of the laboratory staff itself 
(which ought to accumulate to form an asset of some value) 
and likewise the aid and encouragement furnished by the 
laboratory to persons not directly connected with it at all. 
This term, as is readily seen, is the educational one, and its 
components are very difficult both of precise description and of 
comparative evaluation. Looked at in one way, it may be said 
that the first term measures the actual product of the labora- 
tory as an institution for the making of knowledge, while the 
second measures the preparations made for the accomplish- 
ment of future work of many kinds, whether in research or
