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. (39. Paget, 'Lectures on Surgical
Pathology,' 1853, vol. i. p. 71.)

I am informed by Sir James Paget that often several members of a family
have a few hairs in their eyebrows much longer than the others; so that
even this slight peculiarity seems to be inherited. These hairs, too, seem
to have their representatives; for in the chimpanzee, and in certain
species of Macacus, there are scattered hairs of considerable length rising
from the naked skin above the eyes, and corresponding to our eyebrows;
similar long hairs project from the hairy covering of the superciliary
ridges in some baboons.

The fine wool-like hair, or so-called lanugo, with which the human foetus
during the sixth month is thickly covered, offers a more curious case. It
is first developed, during the fifth month, on the eyebrows and face, and
especially round the mouth, where it is much longer than that on the head.
A moustache of this kind was observed by Eschricht (40. Eschricht, ibid.
s. 40, 47.) on a female foetus; but this is not so surprising a
circumstance as it may at first appear, for the two sexes generally
resemble each other in all external characters during an early period of
growth. The direction and arrangement of the hairs on all parts of the
foetal body are the same as in the adult, but are subject to much
variability. The whole surface, including even the forehead and ears, is
thus thickly clothed; but it is a significant fact that the palms of the
hands and the soles of the feet are quite naked, like the inferior surfaces
of all four extremities in most of the lower animals. As this can hardly
be an accidental coincidence, the woolly covering of the foetus probably
represents the first permanent coat of hair in those mammals which are born
