Dr. P. gives us a fauna and flora of Egypt, running further back than Usher's date for the creation, and it cannot be doubted that the drawings are as reliable as those in any modern work on natural history. FOOTNOTES: [198] Natural History of Man and Monkeys. [199] Fauna and Flora within Living Animals, p. 9. [200] Doctrine of the Unity of the Human Race, p. 10. [201] We are told that the pigs in one department of France are all black, in another, all white, and local causes are assigned! When I was a boy, my father introduced what was then called the China hog into the Union District, South Carolina; they were black, with white faces. On a visit to that district about twelve years ago, I found the whole country for 40 miles covered with them. On a visit one year ago, I found they had been supplanted entirely by other breeds of different colors: the old familiar type had disappeared. [202] _Op. cit._, p. 177.

Flourens, Paris, 1855. [207] M. Flourens here, perhaps, speaks too positively. The blood of the apparently lost species will show itself from time to time for many, if not endless generations. [208] _Op. cit._ [209] _Op. cit._, p. 122. [210] It has been objected, that the drawings cannot be relied on, as some of these types are no longer to be found. But there are several well-marked types of domestic animals on the old monuments that no longer exist, because they have been supplanted by better breeds. In this country several varieties of the Indian dogs are rapidly disappearing for the same reason. The llama must give place, in the same way, to the cow and the horse. Many other instances may be cited. [211] _Op. cit._, p. 29. 1854. [212] _Op. cit._, p. 101. [213] _Op. cit._, p. 53. [214] _Geographical Dist._, p. 17. This work, I believe, is not yet issued, but Dr. Pickering has kindly sent me the first 150 pages, as printed. C. Mr. Gobineau remarks (p. 367), that he has very serious doubts as to the unity of origin. "These doubts, however," he continues, "I am compelled to repress, because they are in contradiction to a scientific fact, which I cannot refute--the prolificness of half-breeds; and secondly, what is of much greater weight with me, they impugn a religious interpretation sanctioned by the church."
