Perhaps the simplest and cheapest mode OF ventilation
that could be introduced into school houses churches

tenon OF the trustees Of public schools and of those
who have charge OF churches-is the one adopted
IN the Boston schools short lime since i consists Of

ted from II by space OF several inches By this means
larger OF hollow cylinder of air is interposed between
the heated stove and the air OF the room. and thus the
occupants are protected from the scorching rays Of the
heated IRON. The space between the and the cyln

heated and thus the are constantly supplied with
warm and fresh air.
This simple plan, with The addition of aperures in the
ceiling or in the chimney fues the ceilings, will te
lounda very efficient mode OF ventilation The cost OF
would be mere tThe while il would contribute very
greatly to the health and comfort OF their occ upants
great variety OF modes OF enectiDg ventilation is Of
ieIed u.s. IN which to make selection in altering OF erect,
ing houses, besides those already briefly described
The present is not suitable occasion for going into de-
tail on this subject and will therefore merely mention
The exhausting and receiving cows, by one Of which
air is forced in and by the other drawn out OF apart
men (by system OF tubes passing under the floor and
connected with the ceiling form very efficient OF
ventilation. They be applied 10 weing houses with
little expense, and will venulaie them very thoroughly
even in summer, when heated air cannot be conve-
nenty used This mode is employed in emigrant ships,
agreeably to the act of Congress- Of july s4s and
important contribution 10 the health comfort OF the
numerous passengers board those crowded vessels.
In rooms where nothing better be had, one or two
panes Of zinc, instead Of glass; may be placed in the
upper part OF the window, and perforated with great
number OF minute holes, which will allow the foul air TO
pass out and fresh air to come in II necessary 10 pre-
wind or il very cold, they may be guarded by small
curtain.
Transom lights should be placed all chamber doors
which, moving pIvos, readily be opened and thus
aid in ventilation They particularly important in ho
tells and boarding houses where the inmates specially
apt TO suffer from the want OF fresh air. tsl 3H
The windows OF chambers, too, should extend TO the
floor whenever practicable. as the lower strata OF air in
the room can thus be much readily and edecualy
changed For q similar reason, they snosld be
srucied lei down from the top, to give egress
the air near the ceiling
II has recently been proposed in London to place air
pipes in connexion with those Tor conveying gas into
our apartments. which shall open directly upon the
bufner, order to supply the air necessary 10 the
bnson OF the gas from the external atmospheric instead
OF still further exhsusing and dclerioainG that IN the
room. The plan perfectly feasible and would con-
tribute much towards preserving the air oil our dwellings
pure for the purposes OF respiration. tl a.
My object the discussion oil this subject has been
sim to attract more fully the attention OF the medical
profession and, IL possible, that OF The public. 10 its vital
