This, I imagine, in spite of Professor Huxley’s dictum, is contributing a good deal to the general doctrine of evolution; for though Descartes and Leibnitz may have thrown out hints pointing more or less broadly in the direction of evolution, some of which Professor Huxley has quoted, he has adduced nothing approaching to the passage from Buffon given above, either in respect of the clearness with which the conclusion intended to be arrived at is pointed out, or the breadth of view with which the whole ground of animal and vegetable nature is covered. The passage referred to is only one of many to the same effect, and must be connected with one quoted in “Evolution, Old and New,” {28b} from p. 13 of Buffon’s first volume, which appeared in 1749, and than which nothing can well point more plainly in the direction of evolution. It is not easy, therefore, to understand why Professor Huxley should give 1753–78 as the date of Buffon’s work, nor yet why he should say that Buffon was “at first a partisan of the absolute immutability of species,” {29a} unless, indeed, we suppose he has been content to follow that very unsatisfactory writer, Isidore Geoffroy St. Hilaire (who falls into this error, and says that Buffon’s first volume on animals appeared 1753), without verifying him, and without making any reference to him. Professor Huxley quotes a passage from the “Palingénésie Philosophique” of Bonnet, of which he says that, making allowance for his peculiar views on the subject of generation, they bear no small resemblance to what is understood by “evolution” at the present day. The most important parts of the passage quoted are as follows:— “Should I be going too far if I were to conjecture that the plants and animals of the present day have arisen by a sort of natural evolution from the organised beings which peopled the world in its original state as it left the hands of the Creator? . . . In the outset organised beings were probably very different from what they are now—as different as the original world is from our present one. We have no means of estimating the amount of these differences, but it is possible that even our ablest naturalist, if transplanted to the original world, would entirely fail to recognise our plants and animals therein.” {29b}
