Is there no preventive no cure, for
seasickness: How many millions of
agonized sufferers have asked that
question? Most ocean travellers ha lie

Dr. Barnett says that true seasick-

TO d bilious attacks on shore.
Real seasickness is entirely Diff

A sluggish liver is a very bad COM

According to DR.. Barnett, the real
cause is to be found in the nervous

The special sense through which
the motion Of the ship reaches the
brain is that Of balance. There is in
our heads a pair Of most wonderful
organs which give US this .nse.
These are connected with the ears.
but have absolutely nothing to do
with hearing. In the hard, petrous
part of the temporal Done on each
side of the head are three semi-cir.
cular canals, each one being placed
at right angles to the other two. Each
contains a membraneous canal, the
lining of which secretes a fluid called
endolymph. This apparatus was long
looked upon as an adjunct Of the
mechanism for hearing, because it so
closely connected with the inner ear;
but the nerves that run from it to
the brain are totally distinct from he
auditory nerves. although for a part
OF their course bound up in the same
bundle with them. These nerves run

both sides of the head be
considered together, we see that
they form three pairs, arranged
like the three dimensions Of a cube,
so that they exactly correspond to
the three dimensions Of the space.
Whatever movement the head makes
or whatever movements it il made
to make, as on board a rocking or
pitching ship. at least one pair Of
