“It is inexplicable, on the theory of creation, why a part developed, &c., . . . but, on my view, this part has undergone,” &c. (p. 474).
“On my view” became “on our view” in 1869.
Again:—
“Glancing at instincts, marvellous as some are, they offer no greater difficulty than does corporeal structure on the theory of the natural selection of successive, slight, but profitable modifications” (p. 474).
Again:—
“On the view of all the species of the same genus having descended from a common parent, and having inherited much in common, we can understand how it is,” &c. (p. 474).
Again:—
“If we admit that the geological record is imperfect in an extreme degree, then such facts as the record gives, support the theory of descent with modification.
“ . . . The extinction of species . . . almost inevitably follows on the principle of natural selection” (p. 475).
The word “almost” has got a great deal to answer for.
