n skin of every race is absolutely
one and the same. The only difference between the negro and the white
man is that the negro has two or three times as much of it. Secondly,
that every skin except that of the albino has a certain, and usually a
considerable, amount of this pigment present in it.

"The red hue of health" is even more apt to mislead us, because, being
due to the abundance of blood in the meshes of the skin, many fevers, by
increasing the rapidity of the heart-beat and dilating the vessels in
the skin, give a ruddiness of hue equal to or in excess of the normal.

However, a little careful checking up will eliminate most of the
possible mistakes and enable us to obtain information of the greatest
value from color. For instance, if our patient be of Southern blood, or
tanned from the seashore, the good red blood in his arteries is pretty
safe to show through at the normal blush area on the cheeks; or, failing
that, through the translucent epithelium of the lips and gums. If, on
the other hand, this yellow tint be due to the escape of broken-down
blood-pigments into the tissues, or a damming up of the bile, and a
similar escape of its coloring matter, as in jaundice, then we turn to
the whites of the eyes, and if a similar, but more delicate, yellowish
tint confronts us there, we know we have to deal with a severe form of
anaemia or jaundice, according to the tint. In extreme cases of the
latter, the mucous membrane of the lips and of the gums will even show a
distinctly yellowish hue. The frightful color of yellow fever, and the
yellow "death mask," which appears just before the end of several fatal
forms of blood poisoning, is due to the tremendous breaking down of the
red cells of the blood under the attack of the fever toxins, and their
leaking out into the tissues. A similar process of a milder and less
serious extent occurs in those temporary anaemias of young girls, known
for centuries past in the vernacular as "the green sickness." And a
delicate lemon tint of this same origin, accompanied by a waxy pallor,
is significant of the deadly, pernicious anaemia and the later stages of
cancer.

The most significant single thing about the red flush, supposed to be
indicative of health, is its location. If this be the normal "blush
area," about the middle of each cheek,--which is one of nature's sexual
ornaments, placed, like a good advertisement, where it will attract most
attention and add most beauty to
