Again:-

“Some species of fresh-water shells have a very wide range, and allied species, which, on my theory, are descended from A single source, prevail throughout the world” (p. 385).

“My theory” became “our theory” in 1869.

Again:-

“In the following remarks I shall not confine myself to the mere question of dispersal, but shall consider some other facts which bear upon the truth of the two theories of independent creation and of descent with modification” (p. 389).  What can be plainer than that the theory which Mr. Darwin espouses, and has so frequently called “my,” is descent with modification?

Again:-

“But as these animals and their spawn are known to be immediately killed by sea-water, on my view, we can see that there would be great difficulty in their transportal across the sea, and therefore why they do not exist on any oceanic island.  But why, on the theory of creation, they should not have been created there, it would be very difficult to explain” (p. 393).

“On my view” was cut out in 1869.

On the following page we read—­“On my view this question can easily be answered.”  “On my view” is retained in the latest edition.

Again:-

“Yet there must be, on my view, some unknown but highly efficient means for their transportation” (p. 397).

“On my view” became “according to our view” in 1869.

Again:-

“I believe this grand fact can receive no sort of explanation on the ordinary view of independent creation; whereas, on the view here maintained, it is obvious that the Galapagos Islands would be likely to receive colonists . . . from America, and the Cape de Verde Islands from Africa; and that such colonists would be liable to modification; the principle of inheritance still betraying their original birth-place” (p. 399).

Again:-

“With respect to the distinct species of the same genus which, on my theory, must have spread from one parent source, if we make the same allowances as before,” &c.

“On my theory” became “on our theory” in 1869.

Again:-

“On my theory these several relations throughout time and space are intelligible; . . . the forms within each class have been connected by the same bond of ordinary generation; . . . in both cases the laws of variation have been the same, and modifications have been accumulated by the same power of natural selection” (p. 410).

“On my theory” became “according to our theory” in 1869, and natural selection is no longer a power, but has become a means.
