than the form and size of the cerebral hemispheres, and the richness of
the convolutions upon their surface, while the most changeable
structures of all in the human brain, are exactly those on which the
unwise attempt has been made to base the distinctive characters of
humanity, viz. the posterior cornu of the lateral ventricle, the
hippocampus minor, and the degree of projection of the posterior lobe
beyond the cerebellum. Finally, as all the world knows, the hair and
skin of human beings may present the most extraordinary diversities in
colour and in texture.

So far as our present knowledge goes, the majority of the structural
varieties to which allusion is here made, are individual. The ape-like
arrangement of certain muscles which is occasionally met with* in the
white races of mankind, is not known to be more common among Negroes or
Australians: nor because the brain of the Hottentot Venus was found to
be smoother, to have its convolutions more symmetrically disposed, and
to be, so far, more ape-like than that of ordinary Europeans, are we
justified in concluding a like condition of the brain to prevail
universally among the lower races of mankind, however probable that
conclusion may be.

We are, in fact, sadly wanting in information respecting the disposition
of the soft and destructible organs of every Race of Mankind but our
own; and even of the skeleton, our Museums are lamentably deficient in
every part but the cranium. Skulls enough there are, and since the
time when Blumenbach and Camper first called attention to the marked and
