| over, the truth in the case is Just the opposite
of the received opinion. an Lgssaigne has
shown, by series of Investigations that, CON
trary TO n common opinion. the air in a room
which has served for respiration without being
renewed contains carbonic acid alike in every
part, above as well rs below: the difference
in proportion is but slight: and, when appre-
ciable, there is some reason TO believe that the
carbonic acid is in gyealer quantity in the up
per parts of the room. These experiments es-
tablish the very impOr iant fact, that all the air
in room must be changed, in order 70 restore
its purity" DIR. Wyman says, "Although
carbonic acid is much heavier gas than at.
mospheric air. il does not, from this cause, fall
to the floor, hut is equally diffused throughout
the room. If the gas is formed on the floor
without change Of temperature, this diffusion
may not take place rapidly" Mr.. Tredgold
says, "a mixture Of azote, carbonic acid gas
and vapor at the temperature IL is eircted-
from the lungs-is much lighter than common
air Hence, it rises with such velocity, that il
is entirely removed from us before it becomes
diffused in the atmosphere. But as all gaseous
bodies and vapors intimately mix when suffer.
ed to remain in contact, we see how important
1t is that ventilation should be continual that
the nQxlous gases should be expelled as soon
as generated; and that the yeniiation SHOULD
be from the upper part of room" The great
objection TO ventilation at the upper part of
room is its expensiveness, as it carries off the
heated air There is no such thing as purify
ing air by simply Introducing cold air. More
oyer cold air is necessarily pure, and ought
not TO be admitted into a room at lower tenn
perature than 60 to 6j degrees, and ought not
to be heated in contact with a surface hotter
than - 10 so degrees. l am convinced that
the only rational and elective method of
ventilating our school rooms, filed as they are
with pupils, is to bring in, by force if need be,
pure, warm air at, not one or two but Rumer-
ous places in the floor, and carry out the vitiat-
ed air at the upper part of the room. Most of
the theories and experiments on ventilation,
seem to have had this one idea uppermost,
how theqpIs can our rooms Ie y9Etiated, not
how well?'

by putting furnaces in our buildings they
could be heated at less cost than with stoves,

lieve the rooms we now occupy can be well
ventilated at any reasonable cost. A system
of ventilation to be ,efectual, should be built
up with the building. All our rooms are too
low they do not contain air enough to sup
ply the occupants, while the room is being
heated 1t is very difficult matter to keep
school rooms always at the proper tempera-
ture, Scarsely day pas5es, during which,
the temperature is not, at times, too high or
too low. There should, therefore, be large
supply of air in the room, fit for use, while
the temperature is being regulated. am fully

am happy to be able to state that the term
just closed has been, in every respect, the most
successful of any since my connection with the
schools. All Of our teachers, and most of the
pupils, have been very attentive to their du-
ties, so that good terms work has been nc
complished. Good order has been maintained
generally, throughout the schools. But few
cases of disciplin have been reported to me,
and these have been treated without resorling
to extreme measures, Most of our pupils have
made commendable efforts 70 be pefect in de-
