Note 256 — Chapter VII
Hugh J. C. Beavan translation
“It is one of the clearest facts in the animal, as well as in the vegetable world; all races generally reproduce and perpetuate themselves without mingling and confounding one with the other.”—Prichard, Histoire Naturelle de l’Homme, vol. i., p. 17. Compare Morel, Dégénérescences de l’espèce humaine, p. 2.
