[Footnote 5: In speaking of the foot of his "Pygmie," Tyson remarks,
p. 13:-- "But this part in the formation and in its function too, being
liker a Hand than a Foot: for the distinguishing this sort of animals
from others, I have thought whether it might not be reckoned and called
rather Quadru-manus than Quadrupes, 'i.e.' a four-handed rather than a
four-footed animal."]

[Footnote 6: I say 'help' to furnish: for I by no means believe that
it was any original difference of cerebral quality, or quantity which
caused that divergence between the human and the pithecoid stirpes,
which has ended in the present enormous gulf between them. It is
no doubt perfectly true, in a certain sense, that all difference of
function is a result of difference of structure; or, in other words, of
difference in the combination of the primary molecular forces of
living substance; and, starting from this undeniable axiom, objectors
occasionally, and with much seeming plausibility, argue that the vast
intellectual chasm between the Ape and Man implies a corresponding
structural chasm in the organs of the intellectual functions; so that,
it is said, the non-discovery of such vast differences proves, not that
they are absent, but that Science is incompetent to detect them. A very
little consideration, however, will, I think, show the fallacy of this
reasoning. Its validity hangs upon the assumption, that intellectual
power depends altogether on the brain--whereas the brain is only one
condition out of many on which intellectual manifestations depend;
the others being, chiefly, the organs of the senses and the motor
apparatuses, especially those which are concerned in prehension and in
the production of articulate speech.]

[Footnote 7: It is so rare a pleasure for me to find Professor Owen's
opinions in entire accordance with my own, that I cannot forbear from
quoting a paragraph which appeared in his Essay "On the Characters,
etc., of the Class Mammalia," in the 'Journal of the Proceedings of the
Linnean Society of London' for 1857, but is unaccountably omitted in the
"Reade Lecture" delivered before the University of Cambridge two years
later, which is otherwise nearly a reprint of the paper in question.
Prof. Owen writes: "Not being able to appreciate or conceive of the
distinction between the psychical phenomena of a Chimpanzee, and of a
Boschisman or of an Aztec, with arrested brain growth, as being of a
