boards. After thorough investigation OF
the subject have satisfied myself that the
| discrepancy between the power of the
lungs is not to provide against wear and
tear nor a partial break down of its own
tissues, but to anticipate coming civil
zation, which by virtue of improved ca
| pacity would be able to prevent circula-
| ton of air in buildings, and thus deprive
| their inmates of an adequate supply of
| oxygen. It is in short provision de-
signed to protect teachers and innocents
from being murdered outright by archi-
tects, school boards, boards of trustees and
others who erect buildings at public expense
One by one the chinks and crevices have
been closed until we might exhaust our
rooms with an air pump, by strengthen
ing the doors and windows sufficiently to
resist the outside pressure. Excluding
air is most excellent method of preserving
dead tissues, but live ones languish and
die under the same treatment Rebreath-

vITIATED Alb
is as unhygienic and indecent as reswal-
lowing refractory dinner, but civilization
as represented in the school, the hall, the
church, and even private houses, does not
so regard it. do not believe there is
building in this state in which, if filed to
its capacity, the air would be fit for respi-
ration in half an hour. I have yet to see
the school room that can boast adequate
ventilation. In my own, after three con-
secutive Rotations, in spite of lowered
windows and opened transoms,
THE ALB BECOMES so FOUL
that ono of the brightest pupils gaps
eleven and one-half times in fifty-fve min
utes. You may wonder how I get the
half, but there is no mystery about it
whatsoever. The young man un-
derstands the proprieties of the occa-
sion, and tries to cape with his mouth half
open. Hence it requires twenty two eff
forts to secure the easement of an old
fashioned
CHIMNEY CORNER GARCON,
which consider the proper unit of meas
IRE. This symptom of disease is excess
sively contagious, and if the teacher we're
novice, he would be led to suppose that
a prevalent poultry disease had invaded
the school and disbanded it under the con-
tagious diseases.
vENTILATING BUILDINGS.
There is no difficulty in ventilating
small buildings in which all the rooms can
fire box in the cellar, or with flue built up
with the chimney. In build
ing with 100 rooms the case
far different. To put all these in COM
munication with fiue heated by the Chin
ney would involve great expense; to heat a
fue for each room would be still more ex-
pensive, and yet these are the only alter
natives which our present knowledge of
serostatics give us. In short, the problem
of heating large buildings economically
is yet unsolved. Heating by direct radia-
ton is by far of all the methods the most
vicious, except that, perhaps, of charcoal
pan and the oil stove. Hot air furnaces
must change the air in the room to heat it.
True. they must Do overtaxed, and
the air must be overheated, yet
for every cubic foot of hot
air sent into the room, one cubic foot of
cold air must be expelled from it. It COM
pels the furnace to perform the duty of
force pump in addition to its own and lift
the air through a cold fue forty or fifty
feet IN height or drive it out through the
chinks and crevices of the room.
STEAM COIL
will keep room warm for year without
the change of cubic inch of its atmos-
phere. Heat will dart off from coil when
the air is thick enough with carbonic acid
and animal matter to be cut with a
spatula just as we'll as when it is perfectly
pure. Steam heating by direct radiation
is economical, and when human life is of
| no consequence it may be of some use.
The defect is radical and inevitable, and
the sooner steam filters abandon it the
better. Indirect radiation supplies fresh
air but provides no escape for foul. The
atmosphere of a room at comfortable
temperature will not lift column of cold
air in ventilating hue, and there are but
two ways out Of the difficulty. Heat
enough must be generated to Dive the
air out of the fue or the fue must be
heated. Both expedients involve an ex-
pense which few are willing to incur, and
this brings me to the second part of my
subject, viz: What can the state board of
health do to secure
VENTILATION FOB OUR SCHOOLS?
have already limited that this is the
proper body to investigate thi s
subject, and give US, if possible,
an improved method of heating and venti-
lating school buildings. admire the he
roism with which it fights diphtheria-
energy with which it stamps out smallpox,
but the fatality arising from that disease
is trifing compared with that arising
from imperfect respiration. A climate
which keeps invalids in doors five
months in twelve gives them but lit
tie chance for life, if in addition to con-
finement they are compelled to live ON
stinted supply of oxygen. All person
understand the sensation of cold, and pro-
vide against it, but not all understand the
symptoms or consequences of foul air,
many will not tolerate the least discomfort
from cold, but will sit in a room until they
are on the
VERGE OF AFFIRMATION
without knowing what is the matter with
them. Whatever may be the cause Of
diphtheric, typhoid and other zymotic dis
eases, their peculiar virulence in the winter
season is not without significance.
Food and water are purer in
winter than in summer. NAL
aria is destroyed by frost. Whence the
increase and malignancy of these diseases
| unless from respiratory and dernal excre-
| tlons with which the air of our rooms is
surcharged during this seasonp
