. Dr. W. Ogle has made some curious observations on the
connection between the power of smell and the colouring matter of
the mucous membrane of the olfactory region as well as of the skin
of the body. I have, therefore, spoken in the text of the
dark-coloured races having a finer sense of smell than the white
races. See his paper, Medico-Chirurgical Transactions, London, vol.
liii., 1870, p. 276.

Man differs conspicuously from all the other primates in being
almost naked. But a few short straggling hairs are found over the
greater part of the body in the man, and fine down on that of a woman.
The different races differ much in hairiness; and in the individuals
of the same race the hairs are highly variable, not only in abundance,
but likewise in position: thus in some Europeans the shoulders are
quite naked, whilst in others they bear thick tufts of hair.* There
can be little doubt that the hairs thus scattered over the body are
the rudiments of the uniform hairy coat of the lower animals. This
view is rendered all the more probable, as it is known that fine,
short, and pale-coloured hairs on the limbs and other parts of the
body, occasionally become developed into "thickset, long, and rather
coarse dark hairs," when abnormally nourished near old-standing
inflamed surfaces.*(2)
