108 DARWINIANA. 



of the derivation of species explain which the oppos- 

 ing view leaves unexplained ? 



Questions these which ought to be entertained 

 before we take up the arguments which have been 

 advanced against this theory. "VYe can barely glance 

 at some of the considerations which Darwin adduces, 

 or will be sure to adduce in the future and fuller 

 exposition which is promised. To display them in such 

 wise as to indoctrinate the unscientific reader would 

 require a volume. Merely to refer to them in the 

 most general terms would suffice for those familiar 

 with scientific matters, but would scarcely enlighten 

 those who are not. Wherefore let these trust the im- 

 partial Pictet, who freely admits that, " in the absence 

 of sufficient direct proofs to justify the possibility of 

 his hypothesis, Mr. Darwin relies upon indirect proofs, 

 the bearing of which is real and incontestable ; " who 

 concedes that " his theory accords very well with the 

 great facts of comparative anatomy and zoology 

 comes in admirably to explain unity of composition of 

 organisms, also to explain rudimentary and representa- 

 tive organs, and the natural series of genera and species 

 equally corresponds with many paleontological data 

 agrees well with the specific resemblances which exist 

 between two successive faunas, with the parallelism 

 which is sometimes observe'd between the series of 

 paleontological succession and of embryonal develop- 

 ment," etc. ; and finally, although he does not accept 

 the theory in these results, he allows that "it appears 

 to offer the best means of explaining the manner in 

 which organized beings were produced in epochs an- 

 terior to our own."
