 Existence, or the universal efforts of organisms to secure the 

 necessary means of existence, works without design, but

 the idea long ago, but with admirable industry he employed 

 twenty years in collecting data from actual experience for 

 proving his theory before declaring it. In the "History 

 of Creation" (Chapter VI.), I gave a full account of the 

 method by which he reached his results, as well as of his 

 most important writings, and his life. I shall, therefore, 

 now only allude very briefly to some of the most important

 which appeared in 1794, and in which he expressed views 

 like those of Goethe and Lamarck, though he knew nothing

 Darwin transmitted to his grandson Charles, according to 

 the law of latent transmission (Atavism), certain mole-
