 law. Unless it is borne in mind, the law, especially 

 in the hands of the inexpert, falls into hopeless 

 confusion. We read so often that the ancestral 

 history is identical with the embryonic develop- 

 ment. The one is a recapitulation of the other. 

 This supposed law is then applied in psychology, 

 aesthetics, and many other directions. If it 

 succeeds, there is jubilation. If it does not succeed 

 (as it does not in a thousand cases), the whole 

 blame is thrown on Haeckel. People discover that 

 " the biogenetic law breaks down here," and they 

 throw over Darwinism altogether. 



The second volume of the Morphology is the 

 standing palladium against all this nonsense. It 

 marks off. the real readers and followers of Haeckel 

 from the superficial talkers who run after him
