Famous Authority On Health and
The Marvellous Structure Of
the Eye
Never trifle for a moment
with any eye disorder. Always
seek expert advice and prompt
ly. For the eye is a marvelously
delicate mechanism. Once the
eyeSight is impaired or de-
stroyed 1t may be impossible
to restore it.
The eyeball itself lies in a
bony cavity of the skull to
which the name "orbit" is
given. It is imbedded in a cush-
ion of fat and this insures un-
usual Swiftness and smoothness
of motion. Besides this fat
cushion there is also lining
mucous membrane which fur
ther reduces the friction of mo-
ton.
Six muscles are concerned
with the movement of the eye.
ball. These run to various
points on the surface so that
the eyeball may readily be
moved sideways as we'll as up
and down.
The shape of the eyeball is
that of a sphere but it is not
quite as wide as it is long.
That is, the measurement from
front to back is from one and
three-quarters of an inch to
two inches while the side-to-
side measurement is somewhat
less.
Six investing coats or "tunics"
as we'll as three refracting
media, known as "humors,
make up the eyeball structure.
The outermost coat, and the
one which covers five -sixths of
the eyeball-the part we see
when we look at the eye-is
called the "sclera Sclera is a
firm, fibrinous membrane and
it's purpose is to protect the
delicate structures inside the
eyeball. The one-sixth space
in front, just referred to, is
covered by the "cornea." The
entire eyeball, therefore. is
protected all around on the
outside.
The cornea is directly con-
tinuous with the sclera. It Is
also composed of fibrinous It's
sue but it is transparent and
colorless. The cornea is often
referred to as the window in
the eye"
The cornea, as we'll as the
front portions of the Sclera, are
covered by a delicate mem
brane arising from the mucous
membrane lining the eyelids.
This membrane is known as the
"conjunctiva" and it is kept
moist and glistening by secre-
t1ons from the tear glands. One
such gland is situated at the
outer angle of each orbit.
The next inner coat of the
eyeball is called the "choroid."
1t also occupies the posterior
flve-siXths Of the eyeball.
Next one must consider the
iris" This acts like the shut
ter on a camera and is a thin
curtain of tissue behind the
cornea in front. It's circular
aperture is the pupil" Differ
ent eye colors are due to various
pigment granules deposited In
the iris.
The retina, at the back Of
the eye, is the innermost coat
Of the eyeball, It acts like
Photographic film and is ex-
ceedingly sensitive to light. The
optic nerve" joins with the
retina. BY means Of it images
are transmitted to the brain
proper.
Inside the eyeball hangs the

ball into two chambers. The
front is filled with a watery,
colorless. transparent fluid
called the "aequeous humor,"
While the back portion contains
a similar fluid known as the
"vitreous humor." These
humors maintain the tension
and shape Of the eyeball.
DIR. Bisch's Daily Diet Hint
Premature babies are subject
to ricketts,. For this cod liver
oil, which contains Vitamin D,
should be given as early as the
end of the first week after
birth. After another week
orange juice should also be
given besides the oil and the
regular milk feelings. In all
cases, however, the continued
advice of a physician Is essen
