hat there is
general weakness and deficiency in nutrition. They indicate retarded
development, which may be seated in the central nervous system. The eyes
usually recede during severe diseases. A hyperaemic condition of the
eyelids, with or without inflammation, is always a symptom of a dysaemic
condition of the entire system (scrofulosis). In some cases of
scrofulosis there is not another visible sign on the entire body, and
yet the eyelids and eyelashes, which sticks together most of the time,
tell the story of an inherited condition of dysaemia.

A yellowish hue of the eyes indicates disease of the liver.

The color of the iris does not indicate much in itself, although the
theory of Liljequist, which deserves some attention, claims that if a
person deteriorates in health, the eyes, if originally light blue,
darken more and more and finally change into brown or the color of the
hybrid race. Liljequist's scale of healthy eyes reads: Light blue,
medium blue, dark blue; then light, medium and dark brown. However,
brown eyes do not represent sickness; they but indicate nervousness and
sensibility.

According to Liljequist, individuals belong to the hybrid race when they
are born of parents one of whom has blue eyes and the other brown eyes.
The weaker race transmits the brown colour of its iris to the middle
part of the iris of the child, while the colour of the stronger race
reappears in the outer part of the iris; not, however, as pure blue, but
tinted with a delicate shade of green, in consequence of the light
brownish-yellowish colour which emanates from the central part.

When death is imminent, the iris displays a grayish-black, muddy gray or
muddy brown colour.

The pupil of the eye is irritated in cases of nervous disease and
indicates this condition. In cases where only one pupil is dilated, a
local disease of the optic nerve or one side of the brain is evident. If
the pupils are insensible to external irritations and remain rigid, the
conclusion is that the brain or the spinal cord is badly affected.

It may be stated in a general way that clear, brilliant eyes, (when not
caused by fever) are usually an indication of the good quality of the
blood as well as of all other humours of the body, together with normal
activity of all the central organs.

The _mouth_ and _tongue_: Pathological indications manifested by the
mouth are principally displayed by the lips, which are clear red in
healthy people, while
