ton promised 10 give "some practical
rules for ventilating; also for constructing
public buildings and private dwellings with
a view, to lhoeough ventilation" That the,
subject may be better understood, lei US
pass in review some of the properties ofthe
atmosphere. 1st. 1t is composed of two
elements, Nitrogen and Oxygen. combined
Chemically tits supposedly in definite pro-
portions, and these proportions are con-
start under alF'circumstahces of tempera-
ture, altitude, &c, when free to act.
2. Its elasticity is almost unlimited.
3. Its specific gravity increases or d.
minishes in inverse ratio with the temporal
ture, the warm AIR becoming rarified by
heat, rises up.
4. Its mobility of particles. 1t possesses
this property ina greater degree than any
other ponderable agent. >aJ 5. ,a. la
Wiihthese facts before us it follows.
That, in order to thorough ventilation, there
should be both ingress and egress for the
+air--that these should be as nearly at OPP
posite points as possible--otherwise eddies
WILDE formed as perfectly as in water, to
which in its currents and circulation the
atmosphere bears close analogy.
As the impure air is the raritied air of
the apartment. the ventilation should be
from above. An aperture of one foot
square at the ceiling will afford more eff
cient ventilation than three times that
space at the floor, if the apartment is
heated, or filed with people poisoning the
air by exhalation. A partial ventilation Of
small, lily -contrived rooms, may be tenn
porarily obtained by artificial means. One
is by OF ening the windows and making
fan Of the door--throw it rapidly back and
forth on its HINGES fora few moments and
the air of the entire room will be expelled
and fresh air substituted rg
Those who are under the necessity Of
occupying small, poorly ventilated bed
rooms, especially for the sick. or in the hot
weather, might do well to practice upon
this suggestion.
| In the construction. of Churches and
other public buildings, the ceilings should
be very high. This is important. as well
in reference TO acoustics, as ventilation.
The windows should be large, and reach
nearly to the ceiIng-sbould be SO ar
ranged as to be let down from the top.
! The Church or lecture room should always
be ventilated from above in cold weather.
1t saves the audience from the unpleasant
consequences Of direct current of cold
air. If the ceiling is conca We, there should
be ventilation in the centre, if arched
there should be one at each end Of the room
closed by movable sash.
The same general rules Of construction
will alsoa! ply to private residences. The
largest and best ventilated rooms should
be for dormitories. We occupy them for
a greater proportion of the time than any
other room in our houses. Rooms above
stais in the second or third story are pref
ernbe, they are freezer from dampness than
those on the ground foor. Ii is doubtless
more wholesome to Sleep without fire il

The warming of Churches is Cat least il
this country) a comparatively recent Gus
tom. Our mothers and grandmothers o
New England, a half century ago. carried
their foot-stoves into unwarmed churche,
dressed themselves warmly, and seldom
suffered from cold. When it was proposeC
TO warm their churches. the project me
with strenuous opposition. If churche,
and public buildings cannot be warmed
with open ''6replaces," then those o2
posing "old fogies' were right. Their
cannot be a doubt,in the mind of any re
fleeing man, but that the prevailing ef1emi
macy, and fearful increase of consumptio,
and other pulmonary diseases in all part
of the country, are referable TO suddel
transitions of temperature, from over
heated apartments into the cold air. ii
therefore, stoves and furnaces for heatin,
rooms are at all necessary, they are at leas
but necessary evils.
