If the origin of woTiderful and complex exam])les 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 ? 
I have ah-eady taken up a great deal too much of your time.

have not made any changes which alter the character of the ad-

there are probably verbal errors. I believe, however, that in 
every case the true meaning of the author has been preserved.
