258 H. V. Wilson 



much discussed essay is perhaps not everywhere clear to me. It 

 is manifest however that she consistently subordinates 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 essen- 

 tially that of Sachs and Whitman. 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.
