“On my view these terms may be used literally” (pp. 438, 439).
“On my view” became “according to the views here maintained such language may be,” &c., in 1869.
Again:—
“I believe all these facts can be explained as follows, on the view of descent with modification” (p. 443).
This sentence now ends at “follows.”
Again:—
“Let us take a genus of birds, descended, on my theory, from some one parent species, and of which the several new species have become modified through natural selection in accordance with their divers habits” (p. 446).
The words “on my theory” were cut out in 1869, and the passage now stands, “Let us take a group of birds, descended from some ancient form and modified through natural selection for different habits.”
Again:—
“On my view of descent with modification, the origin of rudimentary organs is simple” (p. 454).
