Thomas Henry Huxley. Evidence as to Man’s Place in Nature. London: Williams and Norgate, 1863.

Displayed are two pages from Huxley’s groundbreaking 1863 book on primate and human paleontology, featuring views of the upper jaws of various primates, ranging from the Cheiromys (the lemur-like Aye-Aye of Madagascar) to Man. Huxley’s point, explained on the facing page, is that “greatly as the dentition of the highest Ape differs from that of Man, it differs far more widely from that of the lower and lowest Apes.”
