84 The American Naturalist. [January, 
unfortunate an error in proof-reading as could have been made. The 
sentence “ I must confess my inability to see why this variation is not 
qualitative as well,” is put in quotation marks, as if it were credited to 
Weismann. The sentence is my own, and would doubtless be indig- 
nantly repudiated by the great apostle of Neo-Darwinism, as it is flatly 
Neo-Lamarckian in fact. 
In explanation I will simply add that I did not read the proof. 
The original manuscript in my possession is correct, although I am. 
not positive that the typewritten copy forwarded to Tue NATURALIST 
is not at fault—C. C. NUTTING.
