!^2 SPREAD OF EVOLUTION. [1861. 



If you come across Dr. Freke on ' Origin of Species by 

 means of Organic Affinity,' read a page here and there. . . .

 to which Bowen and Agassiz, each in their own way, are 

 going. The first denying all heredity (all transmission ex- 

 cept specific) whatever. The second coming near to deny 

 that we are genetically descended from our great-great-grand- 

 fathers ; and insisting that evidently affiliated languages, e. g. 

 Latin, Greek, Sanscrit, owe none of their similarities to a 

 community of origin, are all autochthonal ; Agassiz admits 

 that the derivation of languages, and that of species or forms,
