LETTER 163. TO J.D. HOOKER.
(163/1. The following extract refers to Owen's paper in the "Linn. Soc. Journal," June, 1857, in which the classification of the Mammalia by cerebral characters was proposed. In spite of the fact that men and apes are placed in distinct Sub-Classes, Owen speaks (in the foot-note of which Huxley made such telling effect) of the determination of the difference between Homo and Pithecus as the anatomist's difficulty. (See Letter 119.))
July 5th, 1857.
What a capital number of the "Linnean Journal!" Owen's is a grand paper; but I cannot swallow Man making a division as distinct from a chimpanzee as an Ornithorhynchus from a horse; I wonder what a chimpanzee would say to this? (163/2. According to Owen the sub-class Archencephala contains only the genus Homo: the Gyrencephala contains both chimpanzee and horse, the Lyencephala contains Ornithorhynchus.)
