The Facts of Specific Progress. 171 



parallelism not being perfect, he supplied what was 

 wanting. At his own risk and expense, he lent a 

 few " links" to nature, and completed an imaginary 

 line of her species in history. Finding that, even 

 so, the line in nature's species was not what it 

 should be to match the embryo's line of develop- 

 ment, and was not even a line at all, he introduced 

 into nature a " law of falsifications," whereby she 

 plays him false. That he calls cenogenesis. Then 

 he complements this, of course, with a " law of veri- 

 fications," whereby she is honest with him. This 

 he calls palingenesis. But even so the argument 

 cannot be made to stand, nor his evolution to keep 

 steady on the top of it; so he slips in a practical 

 law of his own personal falsifications, whereby he 

 fabricates in his engravings certain elements to 

 build up his theory anyhow. Now, what is called 

 Science stood everything up to this. But, as great 

 men of his celebrity have a little rivalry and criti- 

 cism playing upon them, his critics and his rivals in 

 the field could not resist the temptation here of ex- 

 posing him baldly. It was the only grievous sin he 

 committed, — to fabricate a few plates. To rail at 

 God was nothing, that was only an offence against 

 piety. But to tamper with an engraving was an in-
