foul efluvia from the lungs or sk1s
should be constantly passing from tho
system, and be as constantly replaced BY
pure mir, that may improve instead Of
impair the health.
The difficulty in ventilating dwellings,
to exchange foul air for fresh in such .
way as to do no harm. is that which
may arise from chilling draughts and
sudden changes of temperature. How
much fresh air must be admitted into q
living room, for any given number OF
human beings, is question that de-
ponds for answer on the number of in
mates, their occupation and state OF
health. It is plain enough that the
amount of vitiated air depends upon the
amount of respiration and perspiration
upon the quantity of waste that exer-
else may expel.
Some scientists, whose experiments
and observations are worthy of all trust.
have reported that each person in q
room should have 1000 cubic feet of air;
or. a room ten feet square and ten feet
high. A school-rOOm forty feet IN
length, ten in height and forty in width.
must hold 10000 cubic feet of air, or air
enough for sixteen persons. Now, many
schoOl-roOms have these dimensions.
and still contain forty scholars. The
amount of fresh air really needed to pre-
vent an undue accumulation of waste
from the skin and lungs should be 49,
600 cubic feet per hour. This amount
of fresh air ought to be so admitted into
the school-roOm as to prevent harmful
and unpleasant draughts. Are any OF
our schOol-rOoms SO constructed rs to
secure this needed amount of fresh air?
We have measured several school-rcoms
in Chicago, and have never found that
they were so arranged as TO yield these
results. Many schOol-rooms do not ap-
proximate it. The results generally are
that the schools have been in session in
winter hardly an hour before the win
dows must be raised, and draughts OF
chilling air be admitted to strike the
heads and shoulders of the inmates.
Similar remarks may be truly male
regarding bedrooms. Physicians often
have occasion to observe that the venti.
lation of sleeping-rooms is still too much
neglected, even by the respectable and
Clearly; and when called to visit ser
wants in the night, the need of ventila-
ton is strongly and strikingly illustra-
ted. The servants are not to blame, or,
at least, not always. Their beds are
usually placed in low attics that have
no means of ventilation, so that, by the
early morning hours, if not before the
growing of chanticleer, the air they are
inhaling is outrageously offensive. Ply
sicians too often observe, also, that in
the sleeping rooms of the poor and ig-
norant hardly 200 cubic feet are allowed
for the inmates. No doubt ignorance OF
the ill results of breathing vitiated all
is one cause of what we often smell.
Every housekeeper should allow the
standard space of 1000 cubic feet fol
each person sleeping within his dwell
ing. In two or more previous essays we
have referred to this subject of ventiia-
ton of bedrooms. We, ourselves, new
er retire to rest without first opening
window ten to thirty inches, and then
keep it open until we rise to prepare fol
the duties of the day.
A cheap and effective way of venti
lating sleeping room is to place a half.
inch board, six inches wide, below the
lower sash. Fit it to each shoulder OF
the window frame. In this way the
outer air will pass freely between the
upper part of the lower sash and the
lower part of the upper sash. If this
arrangement does not admit fresh all
enough, pull down the upper sash al
inch or two, but this is rarely necessary.
