Again:—

“Such is the sum of the several chief objections and difficulties which may be justly urged against my theory” (p. 465).

“My” became “the” in 1869.

Again:—

“Grave as these several difficulties are, in my judgment they do not overthrow the theory of descent with modifications” (p. 466).

This now stands, “Serious as these several objections are, in my judgment they are by no means sufficient to overthrow the theory of descent with subsequent modification;” which, again, is longer, and shows at what little, little gnats Mr. Darwin could strain, but is no material amendment on the original passage.

Again:—

The theory of natural selection, even if we looked no further than this, seems to me to be in itself probable” (p. 469).

This now stands, “The theory of natural selection, even if we look no further than this, seems to be in the highest degree probable.” It is not only probable, but was very sufficiently proved long before Mr. Darwin was born, only it must be the right natural selection and not Mr. Charles Darwin’s.
