He is not to be confused with George Tollet the Shakespearean scholar, and elder brother of Charles. He also lived at Betley Hall, but belonged to the previous generation. Betley is a small village in Staffordshire, only a few miles from Maer, the home of Josiah Wedgwood (1769-1843), Darwin's uncle and father-in-law. It is known (Darwin, F., 1887) that Charles and

But if the Chinese pig were crossed with a race less prolific the offspring would most likely not be so prolific as the original Chinese tho more prolific than the race with which it was crossed. * Breeding in and in as it is called has a manifest tendency to decrease the prolifickness of animals. * Sir John Sebright many years ago published an interesting little book on this subject [see Seebright, 1809].

Just as man can give beauty, according to his standard of taste, to his male poultry, or more strictly can modify the beauty originally acquired by the parent species, can give to the Sebright bantam a new and elegant plumage, an erect and peculiar carriage—so it appears that female birds in a state of nature, have by a long selection of the more attractive males, added to their beauty or other attractive qualities. *  Descent, p. 211 [page
