[Variation 2d ed. 1: 54: "M. Sanson17 thinks that he has proved that two distinct species have been domesticated, one in the East, and one in North Africa; and that these differed in the number of their lumbar vertebra and in various other parts; but M. Sanson seems to believe that osteological characters are subject to very little variation, which is certainly a mistake.

Variation 2d ed. 1: 77 n23: "Nevertheless the difference in the number of the ribs in pigs deserves notice. M. Sanson gives the number of lumbar vertebræ in various pigs; 'Comptes Rendus,' lxiii. p. 843."]
