th numerous long hairs. Rayer speaks
of several instances of this kind. In one the part affected by a
blister in a child of two became covered with hair. Another instance
was that of a student of medicine, who after bathing in the sea for a
length of time, and exposing himself to the hot sun, became affected
with coppery patches, from which there sprang a growth of hair.
Bricheteau, quoted by the same authority, speaks of a woman of
twenty-four, having white skin and hair of deep black, who after a long
illness occasioned by an affection analogous to marasmus became
covered, especially on the back, breast, and abdomen, with a multitude
of small elevations similar to those which appear on exposure to cold.
These little elevations became brownish at the end of a few days, and
short, fair, silky hair was observed on the summit of each, which grew
so rapidly that the whole surface of the body with the exception of the
hands and face became velvety. The hair thus evolved was afterward
thrown out spontaneously and was not afterward reproduced.

Anomalies of the Color of the Hair.--New-born infants sometimes have
tufts of hair on their heads which are perfectly white in color.
Schenck speaks of a young man whose beard from its first appearance
grew white. Young men from eighteen to twenty occasionally become gray;
and according to Rayer, paroxysms of rage, unexpected and unwelcome
news, diseases of the scalp such as favus, wounds of the head, habitual
headache, over-indulgence of the sexual appetite, mercurial courses too
frequently repeated, too great anxiety, etc., have been known to blanch
the hair prematurely.

The well-accepted fact of the sudden changing of the color of the hair
from violent emotions or other causes has always excited great
interest, and many ingenious explanations have been devised to account
for it. There is a record in the time of Charles V of a young man who
was committed to prison in 1546 for seducing his girl companion, and
while there was in great fear and grief, expecting a death-sentence
from the Emperor the next day. When brought before his judge, his face
was wan and pale and his hair and beard gray, the change having taken
place in the night. His beard was filthy with drivel, and the Emperor,
moved by his pitiful condition, pardoned him. There was a clergyman of
Nottingham whose daughter at the age of thirteen experienced a change
from jet-blackness of the hair to white in a single night, bu
