in a series of brief studies marked with his well known skill 
and accuracy of observation and statement. I fully agree 
with him as to the great importance of the facts. 
The general point of view entertained by Mrs. Andrews in 
her much discussed essay is perhaps not everywhere clear to 
me. It is manifest however that she consistently subordi- 
nates the idea of the individual, whether entire organism or 
cell, to that of the specific substance of which it is but a more 
or less detached piece. As far as the cell is concerned this 
point of view seems to be essentially that of Sachs and Whit- 
man. Mrs. Andrews extends it to the whole organism, and I 
may say that this way of looking at an animal or plant (or 
piece of the same) is in my opinion a habit of mind that will 
justify itself and indeed is doing so today, in that it leads to 
discoveries concerning the nature of protoplasms as revealed 
by what they can do.
