Again, the geographical distribution of existing animals 

 has been seen to present difliculties which, tliough not 

 themselves of any great weight, yet have a certain value 

 when taken in conjunction witli all the other objections. 



The facts of homology, serial, bilateral and vertical, have 

 •also been passed in review. Sucli phenomena, it has l)een 

 contended, are not explicable without admitting the action 

 of what may most conveniently be spoken of as an internal 

 power, the existence of which is supported by facts not 

 only of comparative anatomy, but of teratology and patho- 

 logy also. Besides this, " Natural Selection " has been shown 

 to be impotent to explain tliese phenomena, while the exist- 

 ence of such an internal power of homologous evolution 

 diminishes the a priori improbability of an analogous law 

 of specific origination. 



All these various considerations have been supplemented 

 by an endeavour to show the utter inadequacy of ^Ir. 

 Darwin's theory with regard to the higher psychical phe- 

 nomena of man (especially the evolution of moral per- 

 ceptions), and with regard to the evolution of individual 

 organisms by the action of Pangenesis. And it has been 

 implied that if Mr. Darwin's latter hypothesis could be 

 shown to be untenable, an antecedent doubt would be 

 thrown upon his other conception, namely, tlie theory of 

 '' Natural Selection." 



A cumulative argument thus arises against the pre- 

 valent action of " Natural Selection," which, to the mind 

 of the author, is conclusive. As before observed, he was 

 not originally disposed to reject ]\lr. iJarwin's fascinating
