TAKE CARE OF THE EYES.


Everybody recognizes the important
rart the sight plays in the happiness of
this life. and vet there is hardly any
ching which is used with such prodigal-
nv To be blind, TO be shut out from
ailthe beautiful things of the world, to
seel but not to see the blessed sunlight,
i hear the rushing wind and falling
rain. but with no sight of the feecy
olo,,ds, the waving trees. or the blue of
she heavens, to catch the fragrance Of
she flowers, with Tzo view of their dove
I;ness. to hear the voices of loved ones,
while darkness rests upon their faces,
aIl this is horrible; and yet most people
run the risk of bringing about this hor-
ror by the esrelessness and persistent
oyer.taxing of the eyes year after year.
ii seems to be the impression that these
orrans must take care of themselves.
No doubt the general health has much

ANYBODY will notice how the eyes give

often cause diRnness of vision, which.
however, is frequently disregarded. and
the person works right on, determined,

question of yielding to bodily pain, but
Of permanently iniuring the eyes by
forcing them beyond the;r strength.
They g,ist be favored at such seasons
or their power viii be impaired beyond
remedy It may not be felt or noticed
ct the time. but In years to come such
abuse for that is what it is-tells sadly.
No one would think of using weak
ened arm to lift heavy weights. but the
eyes must do duty under all circum-
stances.
do not propose to enter into any
minute description of the anatomy of
the eye. As you know, it is an exceed
ingly delicate organ, that needs to be
treated with even more consideration
than the ear. First we have the eye
lids for protection. They are two PHI.
able folds of skin, the upper one of
which can be moved at will and made
to shut down and cover the eve COM
pletely. Upon their edges grow the
eyelashes which help still further to
keep out foreign substances. The eye
itself is spherical in forTa ard Is placed
ina bony socket. You know how il is
guarded upon all sides IN tAis way.
There are six muscles attached both to
the outer susfacs and to the bones of the
socket, BY which 1t is moved In all di-
gections. It is composed of three LAYERS
or coats lying one over the other, and
contain certain humors that. act as
lenses. The optic nerve enters at the
tack and spreads out over the inner
coat or retina.
The outer coat is called the scIerotic,

We see the pupil and iris. The pupil is

the 2. eornea, and is really the opening
through which the rays of light pass to

Next to the sclerotic coat comes tha

nerve surface, and upon it all images
are formed. Within these coats are Che
