[Footnote 7: Mr. Alfred Russel Wallace writes: "We claim for Darwin
that he is the Newton of natural history, and that, just so surely as
that the discovery and demonstration by Newton of the law of
gravitation established order in place of chaos and laid a sure
foundation for all future study of the starry heavens, so surely has
Darwin, by his discovery of the law of natural selection and his
demonstration of the great principle of the preservation of useful
variations in the struggle for life, not only thrown a flood of light
on the process of development of the whole organic world, but also
established a firm foundation for all future study of nature"
