If the origin of wonderful and complex examples of instinct 
such as these cannot be explained by the Lamarckian theory but 
readily by the Darwinian, why should not natural selection also 
offer an adequate explanation of all other cases? 
[ have already taken up a great deal too much of your time. 
[much hope to have the opportunity to-night of hearing many 
stronger arguments in favor of the Lamarckian theory than it has 
been my opportunity to hear hitherto. 
Note.— In revising the short-hand transcript for publication, I 
have not made any changes which alter the character of the ad- 
dress. It remains the record of a spoken address, the sequence 
and continuity of which were maintained by the use of brief notes. 
I have not verified the quoted opinions and words of others, and 
there are probably verbal errors. I believe, however, that in 
every case the true meaning of the author has been presagved.
