[48] M. Broca has shown (‘Journal de Physiologie,’ tom. ii. p. 353) that Buffon’s experiments have been often misrepresented. Broca has collected (pp. 390-395) many facts on the fertility of crossed dogs, wolves, and jackals.
[49] ‘De la Longévité Humaine,’ par M. Flourens, 1855, p. 143. Mr. Blyth says (‘Indian Sporting Review,’ vol. 2 p. 137) that he has seen in India several hybrids from the pariah-dog and jackal; and between one of these hybrids and a terrier. The experiments of Hunter on the jackal are well-known. See also Isid. Geoffroy St.-Hilaire, ‘Hist. Nat. Gén.,’ tom. iii. p. 217, who speaks of the hybrid offspring of the jackal as perfectly fertile for three generations.
