A CORRECTION 
In a review of the second edition of JOHANNSEN’S Elemente der 
exakien Erblichkeitslehre in the last number of this journal (Bor. Gaz. 
57239. 1914), I made a very stupid error for which I wish to apologize 
to Dr. JoHANNSEN and to the botanical public. From the preface, in 
Which JOHANNSEN disclaims being a “pure Weismannian,” and from 
the sympathetic treatment of Semon in one of the chapters on the 
influence of environment, I obtained the idea that he retained a 
Lamarckian attitude, although disclaiming belief in experimental proof 
of the inheritance of acquired characters. Oddly enough, other readers 
of the book gained the same impression, as I learned from various 
conversations. This phase of the subject being necessarily somewhat 
ancient biological history I passed it by rather hurriedly. Recently I 
have read the two chapters concerned carefully, and find that JoHANN- 
SEN is even mote of a Weismannian in his essential principles than I 
had thought. His wish not to be considered as a “pure Weismannian”’ 
evidently rests entirely upon his opposition to WEISMANN’s morpho- 
logical conceptions, as I stated in the review.—E. M. East.
