CONSUMPTION EXPLAINED.
Passing backward through the mouth we
enter the pharynx by the fauces In the
floor Of the pharynx is q trap door called the
,epiglottis, which We lift and let ourselves
down into the trachea. Sliding between the
vocal chords, we find ourselves in the
bronchial tube; turning to the right, we
pass lnnumerable forks in our road, but we
soon reach the right lung. The tubes by
this time become so small that we must
crawl in order TO get any further. A little
way on and we will come 70
place Ehere we can stand again; in
deed, we are already there. Now we
are In the lung proper-before we have
only been in the bronchial tubes. The
place in which we now stand is called the
air-chamber, or sac, the dilated extremity of
the tube. On every side of this little room are
inches or excavations, too small for Us to
enter. but we can examine one, for you
notice that most of them are opening and
closing each time the air comes in and out Of
this chamber. These tiny places are
in them that the air is able to
reach the blood The chamber in which we
are is one-fftieth Of an inch in diameter,
but those little cells are only one-three-
hundTedthof of an inch. They are arranged on
the walls on all sides Of us, and the ceiling
above exactly like the cells OF honey-comb,
each cell divided from its neighbor
by q thin partition. Look close and
you will see that these partitions are
made up of perfect network of small
blood-VesseIs, and every time the cells open
to allow air to enter them the walls are
stretched and the air comes in contact with
the exceedingly thin blood-vessels, so thin
that when the air touches them the oxygen
passes the delicate coat of the vessel and
gets into the blood, and is carried by the
blood into every part of the system. There
are many hundred chambers in the lungs
like the one we are in, and millions of air
cells like the ones we are looking at. The
coats or walls of these vessels are thinner
than anything you ever saw before, and as
the blood surges through them, and the air
rushes against them, it is quite astonishing
that accidents do not occur oftener. Every
thing depends on the elasticity of these
delicate coats. If they get fabby the
blood dams up in them and forces some
of the Watery portion of the blood into the
little cells and fills them up entirely. By
coughing some of them are emptied, but
many OF them remain full, which dries
down in cheesy mass, which the doctors
call tubercle, and it there are many of
them in the lungs it is called tuberculosis,
or consumption. A great many slight
causes are sufficient to cause these vessels to
allow some of their serum to escape into
the air-cells and set up this dread disease
colds, catarrh, irritating substances in the
atmosphere, to which everybody is exposed
It is really surprising that in changeable
climate that consumption does not occur
DIT, : =
away more people every year than all epi-
denies and contagious diseases together
Every breath we draw brings in contact
with these vessels, whose delicacv surpasses
sir-laden dust, disease germs
and harmful gases. Whether these delicate
vessels will be so irritated as to produce a
of the blood in them depends en-
tirely on the strength and elasticity of the
coat Of these vessels
All consumption medicines have had for |
their purpose to expel these tiny masses (or |
tubercles) from the lungs after they are |
formed, but had no power to prevent their |
formation. It is just here that the superior |
virtue Of Pe-ru-na is to be explained. Pc |
ru-na operates 10 give tone and elasticity to |
these very fragile blood vessels, and to pre-
vent the further accumulation OF the tuber- |
cles. AS soon as the little vessels that sur
rouno eacn alf-celt are strengthened by the |
action Of Pe-ru-na, not only are the tuber-
cles expelled that are already formed, but,
their former elasticity being regained, no
more are formed. There is no stage of con-
or any lung trouble to which Pc
ru-na is not applicable, as it
is certain to restore the strength
of the blood vessels in the lungs and |
bronchial tubes, preventing congestions
and inhammations, upon which all lung
diseases depend. 1t is not with Pe-ru-na as
with many lung remedies, which relax or
oosen the lungs, hoping by still further re-
axing the blood vessels that the escape of
he serum from them will wash out the old,
,heesy masses, or tubercles from these little
'ells (and no doubt but they are partially
in 50 doing), but they hasten
'ather than prevent. the formation of new
mes. The effect OF Pe-ru-na is not to relax,
tut to give greater tone to the vessels, and
elasticity to the walls of the air cells, ex-
'elling the tubercles and preventing their
ormstion. The Ills of Life, sent free on
DUPLICATION to the Pe-ru-na Medicine Co.,
u Columbus, o., gives testimonials to the
ficacy of this wonderful remedy.
