Botany and Zoology. 441 
Sci. Wat. in 1862, vol. xvi, pp. 309-344,—which we have not space to 
analyze,—is worthy of attention from the general inquirer, on account of 
its analysis of the Tertiary flora into its separate types, Cretaceous, Austral, 
Tropical, and Boreal, each of which has its separate and different history, 
—and for the announcement that “the Aiatus, which, in the idea of most 
geologists, intervened between the close of the Cretaceous and the. begin- 
ning of the Tertiary, appears to have had no existence, so far as concerns 
the vegetation ; that in general it was not by means of a total overthrow, 
more easily than in our [European] soil—less vast and less extended south- 
ward—refuge from ulterior revolutions.” The extinction of species is at- 
ged 
North America and Europe in former times. Most naturalists and geolo- 
gists reason in the same way,—some more cautiously than others,—yet 
perhaps most of them seem not to perceive how far such inferences 
sumptions in their favor,—and to be, perhaps, quite as capable of being 
turned to good account as to bad account in natural theology.

“The a pest of interference can mean nothi re than that the 
Supreme Will has so moved the hidden springs of nature that a new issue arises on 
iven circumstances. inary issue is supplanted by a hi ; , 
essential facts before us are a certain set of phenomena, and a r Will movil 
m. How moving them? i uesti r buman definition; the answer to whi 
does not and cannot affect the Divine meaning of the hen we reflect 
that this Higher Will is everywhere reason and wisdom, it seems a juster as well 
as a more oi rehensive view to regard it as operating by subordination and evo- 
lution, rather by interference or violation.”
