"Natural Selection" also has been shown to be impotent to explain these phenomena, while the existence 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 Mr.Darwin's theory with regard to the higher psychical phenomena of man (especially the evolution of moral conceptions), and with regard to the evolution of individual organisms by the action{225} of Pangenesis.

And it was implied that if Mr.Darwin's latter hypothesis can be shown to be untenable, an antecedent doubt is thus thrown upon his other conception, namely, the theory of "Natural Selection." A cumulative argument thus arises against the prevalent action of "Natural Selection," which, to the mind of the Author, is conclusive.

As before observed, he was not originally disposed to reject Mr.Darwin's fascinating theory.

Reiterate endeavours to solve its difficulties have, however, had the effect of convincing him that that theory as the one or as the leading explanation of the successive evolution and manifestation of specific forms, is untenable.

At the same time he admits fully that "Natural Selection" acts and must act, and that it plays in the organic world a certain though a secondary and subordinate part.
The one _modus operandi_ yet suggested having been found insufficient, the question arises, Can another be substituted in its place?
If not, can anything that is positive, and if anything, what, be said as to the question of specific origination?
Now, in the first place, it is of course axiomatic that the laws which conditioned the evolution of extinct and of existing species are of as much efficacy at this moment as at any preceding period, that they _tend_ to the manifestation of new forms as much now as ever before.
