called pure. The oxygen Of this CON-
pound has to perform q function u VI
tai Importance when breathed into the
lungs. 1t gives new life to the blood
at every breath, and It requires all the
oxygen contained in the air in its nat-
ural state to perform this vital function
BEAUTIFULLY. If the air becomes in any
degree overcharged with carbonic acid,
it Is to that extent deprived Of the life
giving oxygen, and in precise proper
ton as the overcharse increases, the
healthfulness of the air decreases, and
becomes dangerous, and ultimately
fatal. And this increase Of carbonic
acid, and decrease Of oxygen, Is what
l. going onall the time in rooms crowd
ed with men or women or children, In
all cases where there Is no adequate
means provided for the exit of the foul
or de~vitalized air, and the introduction
Of fresh supplies Of pure air from the
atmosphere outside. The..provlding OF
such means for changing or frsshening
the air is what is meant by "~ventila-
tion." A few words will show how
the foullng or vitiation of the air, just
referred to, in crowded and close
rooms, comes about. When the air Is
brsathed into the lungs it passes into
an immense number Of small cells,
where 1t comes into contact with the
blood brough there through the veins
in the course of circulation. This
blood Is loaded with carbon, taken up
from the body, and has been to a
large extent deprived Of the oxygen
it possessed when it passed from the
lungs into the arteries. 1t has been
brought back into the minute cells In
the lungs to get rid Of its local carbon,
and to absorb n new supply Of the
h~ealth-givfng and life-giving oxygen.
This Is done by being brought into on
tact with the air taken into the lungs ut
every breath. The air discharges a
portion of Its oxygen into the blood in
the lungs, and with another portion
takes up the overcliarge Of carbon with
which the blood comes loaded from
the veins. The air Is now breathed out
from the lungs, deprived Of Its health
full oxygen, and charged with the sur
plus carbon from the blood in the
form of carbonic acid. 1t Is now foul
air, and goes out into the room with
every breath to vitiate the natural air.
II the room were closely sealed up,
the breathing of n person, in a
few hours, would deprive the air in 1t
Of enough Of its oxygen, and replace
it with sufficient carbonic acid to cause
death. Nc room, however, is so closely
sealed; but q great many rooms, pub
lie halls, schools, theatres and churches
are so badly constructed and so poorly
provided with means for the exit Of
foul air, and the admission of fresh
air, that they are not fit for the assem-
blage in them Of the large numbers Of
persons they sometimes contain, for
the more numerous tho breathers the
more rapidly and injuriously the pro-
cess of foullng the air goes on. Twenty
girls or boys, crowded into n school
room fifteen or twenty feet square,
without adequate means for carrying
off the air breathed out from the lungs
and bringing in fresh supplies Of air
from the outside of the building, will
soon make the air in such a building
unfit to breathe. They will become
uneasy and tidgety, for which some of
them may possibly be punished; many
Of them will DO unable to study, for
which they will probably be degraded;

will wonder "what is the matter?'
Some young constitutions are able to
resist this for awhile, but all suffer, and
some sink into early graves on account
Of It, and all because people ignore the
fact that when the same air Is breathed
over and over and over again, It must
be deprived Of its health and l~ife-giving

to all rooms in all buildings, public or

the foul air is kept in and the pure air
