[3] For Europe see Bechstein, ‘Naturgesch. Deutschlands,’ 1801, B. i., s. 505. Several accounts have been published on the fertility of the offspring from wild and tame swine. See Burdach’s ‘Physiology,’ and Godron ‘De l’Espèce,’ tom. i. p. 370. For Africa, ‘Bull. de la Soc. d’Acclimat.’ tom. iv. p. 389. For India, see Nathusius, ‘Schweineschädel,’ s. 148.

[6] See J. W. Schütz’ interesting essay, ‘Zur Kenntniss des Torfschweins,’ 1868. This author believes that the Torfschwein is descended from a distinct species, the S. sennariensis of Central Africa.
