THEORIES OF LAMARCK AND DARWIN 391 
“A deer with a neck which was longer by half 
Than the rest of his family’s—try not to laugh— 
By stretching and stretching became a giraffe, 
Which nobody can deny.” 
The clever young woman, Miss Kendall, however, in her 
Song of the Ichthyosaurus, showed clearness in grasping 
Darwin’s idea when she wrote: 
“Ere man was developed, our brother, 
We swam, we ducked, and we dived, 
And we dined, as a rule, on each other. 
What matter? The toughest survived.” 
This hits the idea of natural selection. The other two illus- 
trations miss it, but strike the principle which was enunciated 
by Lamarck. This confusion between Lamarckism and Dar- 
winism is very wide-spread. 
Darwin’s book on the Origin of Species, published in 
1859, was epoch-making. If a group of scholars were asked 
to designate the greatest book of the nineteenth century— 
that is, the book which created the greatest intellectual stir — 
it is likely that a large proportion of them would reply that 
it is Darwin’s Origin of Species. Its influence was so great 
in the different domains of thought that we mav observe a 
natural cleavage between the thought in reference to nature 
between 1859 and all preceding time. His other less widely 
known books on Animals and Plants Under Domestication, 
the Descent of Man, etc., ctc., are also important contributions 
to the cliscussion of his theory. A brief account of Darwin, 
the man, will be found in Chapter XIX.
