same--the lower Apes and the Gorilla would differ more than the Gorilla
and the Man. I cannot attempt in this place to follow out all these
comparisons in detail, and indeed it is unnecessary I should do so. But
certain real, or supposed, structural distinctions between man and the
apes remain, upon which so much stress has been laid, that they require
careful consideration, in order that the true value may be assigned to
those which are real, and the emptiness of those which are fictitious
may be exposed. I refer to the characters of the hand, the foot, and
the brain.

Man has been defined as the only animal possessed of two hands
terminating his fore limbs, and of two feet ending his hind limbs,
while it has been said that all the apes possess four hands; and he has
been affirmed to differ fundamentally from all the apes in the
characters of his brain, which alone, it has been strangely asserted
and re-asserted, exhibits the structures known to anatomists as the
posterior lobe, the posterior cornu of the lateral ventricle, and the
hippocampus minor.

That the former proposition should have gained general acceptance is not
surprising--indeed, at first sight, appearances are much in its favour:
but, as for the second, one can only admire the surpassing courage of
its enunciator, seeing that it is an innovation which is not only
opposed to generally and justly accepted doctrines, but which is
directly negatived by the testimony of all original inquirers, who have
specially investigated the matter: and that it neither has been, nor
can be, supported by a single anatomical preparation. It would, in
fact, be unworthy of serious refutation, except for the general and
natural belief that deliberate and reiterated assertions must have some
foundation.
