The Ear and the Brain.
ANY disease that attacks the middle ear
or maStofd cavity is very grave and DAN
gerous, because these parts are tt situated e..
SO close 10 the brain. Inflammation IN
these structures is liahle 10 extend TO tne
brain. and every year disease set up IN
the middle ear causes the death OF oo,ooo

It was such disease that destroyed
the life of the late Roscoe Conklin and
and peculiar actions at times are attributed
to a chronic disease oil the middle ear from
which he suffers.
What Constitutes the Ear.
while everyone knows that, situated

there is tube which passes from the
cavity of the middle ear down into the
throat. This is called the eustachian tube,
and it carreis air into the deeper recesses e
of the ear Without air In the middle
ear no sound can be heard. The ear
needs air to convey the sound TO the
parts which imprison it and repeat 1T TO

Eve and Ear Compared.
The eye is but a iooking-glass with a
cable composed of nerves passing out or
its back surface and reaching into the
brain The mirror of the eye takes up
pictures of the objects that are presented
to it. and molding. this picture on the

mold objects except by the aid OF hight.
The ear, consisting as II does OF tube
