438 CONCLUDING REMARKS. 



refutation of Darwinism, but they do not suffice to en- 

 title the theory of Reversion to a place within the body 

 of positive truths. 



We have, however, supplemented such arguments and 

 evidences, with adequate, scientific proofs of the truth of 

 the theory of Reversion, and with positive disproofs of 

 the theory of Darwin. The phenomena of Crossing 

 and of Close-Interbreeding accomplish these ends, 

 with the full, unerring force of demonstration. 



These phenomena declare the law, beyond all con- 

 troversy or cavil, to be, viz., that the positive varia- 

 tions in each species are but the regain of what was 

 previously lost by such species ; that that organic struct- 

 ure which is the sum of all the possible developments 

 of its species, is alone consistent with full physiological 

 integrity ; that there is a limit to Variation in both di- 

 rections, in the direction of increase and in the direc- 



spring ; which occasions the transmission to an individual of either 

 sex of the primary and secondary, sexual characters of the opposite 

 sex ; the philosophy of hydrophobia, of catamenia, of petrifaction, of 

 the several phases of metamorphosis, and of monstrosities ; and the 

 phenomena of embryology, will receive an explanation as complete as 

 that which has been given of the phenomena of Crossing and Close- 

 Interbreeding. This synthesis — the principles of which shall be 

 evolved from the facts, and descend again to the facts, by as rigorous 

 processes of induction and deduction, as have characterized the pres- 

 ent work — will include the true theory of classification ; the explana- 

 tion of numerous, recondite, psychological problems; an explana- 

 tion of the history and function of the caecum; and such a full 

 and detailed explanation of the function of the cerebellum, as 

 harmonizes the two seemingly conflicting classes of facts which now 

 are appealed to by the advocates, respectively, of the two prevailing 

 theories.
