Note 27 — II ON THE RELATIONS OF MAN TO THE LOWER ANIMALS.

“More than once,” says Peter Camper, “have I met with more than six lumbar vertebræ in man.... Once I found thirteen ribs and four lumbar vertebræ.” Fallopius noted thirteen pair of ribs and only four lumbar vertebræ; and Eustachius once found eleven dorsal vertebræ and six lumbar vertebræ.—“Œuvres de Pierre Camper,” T. 1, p. 42. As Tyson states, his “Pygmie” had thirteen pair of ribs and five lumbar vertebræ. The question of the curves of the spinal column in the Apes requires further investigation.
