And if, instead of putting Hapale out of its natural
place, as Professor Bischoff most unaccountably does, we write
the series of animals he has chosen to mention as follows: Homo,
Pithecus, Troglodytes, Hylobates, Semnopithecus, Cynocephalus,
Cercopithecus, Macacus, Cebus, Callithrix, Hapale, Lemur,
Stenops, I venture to reaffirm that the great break in this
series lies between Hapale and Lemur, and that this break is
considerably greater than that between any other two terms of
that series. Professor Bischoff ignores the fact that long
before he wrote, Gratiolet had suggested the separation of the
Lemurs from the other Primates on the very ground of the
difference in their cerebral characters; and that Professor
Flower had made the following observations in the course of his
description of the brain of the Javan Loris: (75. 'Transactions
of the Zoological Society,' vol. v. 1862.)
"And it is especially remarkable that, in the development of the
posterior lobes, there is no approximation to the Lemurine, short
hemisphered brain, in those monkeys which are commonly supposed
to approach this family in other respects, viz. the lower members
of the Platyrrhine group."
So far as the structure of the adult brain is concerned, then,
the very considerable additions to our knowledge, which have been
made by the researches of so many investigators, during the past
ten years, fully justify the statement which I made in 1863.
