Some of this fell out again when it had grown
from three to four inches; the rest changed color at different
distances from its end and grew of a chestnut color from the
roots. The hair, half black, half chestnut, had a very singular
appearance.
Alibert and Beigel relate cases of women with blond hair which
all came off after a severe fever (typhus in one case), and when
it grew again it was quite black. Alibert also saw a young man
who lost his brown hair after an illness, and after restoration
it became red. According to Crocker, in an idiotic girl of
epileptic type (in an asylum at Edinburgh), with alternating
phases of stupidity and excitement, the hair in the stupid phase
was blond and in the excited condition red. The change of color
took place in the course of two or three days, beginning first at
the free ends, and remaining of the same tint for seven or eight
days. The pale hairs had more air-spaces than the darker ones.
There was much structural change in the brain and spinal cord.
Smyly of Dublin reported a case of suppurative disease of the
temporal bone, in which the hair changed from a mouse-color to a
reddish-brown; and Squire records a congenital case in a deaf
mute, in whom the hair on the left side was in light patches of
true auburn and dark patches of dark brown like a tortoise-shell
cap; on the other side the hair was a dark brown.
