species; or, Darwinism. 



98. We quoted the German Professor Virchow as 

 saying at the Congress held in September, 1887, at 

 Wiesbaden, that the transformation of one species 

 into another was a theory so destitute of proof, as 

 to find no place as yet in the domain of science. 

 The most ardent partisans of transformation, like 

 Haeckel and Vogt, are forced to admit separate ori- 

 gins for the principal classes of species. With this 

 utterance of the Berlin professor others agree, 

 while still professing sympathy for the theory of 

 Mr. Darwin on the descent of species. Thus Pro- 

 fessor Huxley, in his recent notice on Darwin in 

 the Proceedings of the Royal Society, practically 

 concedes that natural selection by the survival of 

 the fittest cannot be the only or chief law to ex- 

 plain the origin of species. On other occasions, as 

 in his work on Man's Place in Nature, he affirms 

 that the necessary physiological proof, which re- 

 gards the sterility and fertility of species, is still 

 wanting to establish Darwinism.
