THE BODY AND IT'S HEALTH.

AvERTING ATTACKS OF AsrHMA.-Ac-
cording to the Journal de Medicine, of
Paris, the fumes of bromohydrate of am.
monia have beneficial effest in asthma
and bronchitis. BY an inhalation of the
fumes, under certain conditions, an at
tack of asthma may be averted.
MORE AxKsHETIc AND ANrIsRprIc
AGENTs.-lt seems that the use of solid
carbonic acid as an an9sthetic has been
made the subject of patent by the
well-known DIR. Robert Wiesendanger
of Hamburg, When the liquefied gas is
poured from the iron cylinder in which it
is compressed, it rushes out in the form
of white mist, which may be collected
as fakes of pure carbonic acid snow end
pressed into solid masses that will st
a number of hours. Carbonic acid us
solidiied produces intense cold, CHI
may be made to benumb any part of he
body to such an extent that minor su,gi-
cal operations are made painless. This
has been practiced with such certainty
that, lat the Hamburg Hospital, one of
the,experimental cases was that of boy
of thirteen who watched without shrink
ing while deep cut FIVE inches long was
made in his leg.
VENTILATIoS. - The healthy atmos-
phere in room is ono in which the air
is changed to the extent of 5000 cubic
feet per hour per adult inmate. The air
admitted need not be cold warmed air,
so long as it is fresh, is of course prefer,
able to cold air in winter, but in some
way the air must be brought in if we are
10 continue in health. There are various
ways of doing this. One is by admitting
cold air so that it is directed upward
toward the ceiling, where the air of
room is ut the highest temperature; the
cold stream is then heated in its passage
as it falls to the lower level for breath
ing. But in large rooms, to utilize at its
best this current, there should be in the
skirting outlets communicating with a
heated up-cast fiue, which will draw
away the heavy air near the door. In
ceases where there is heating by hot
water coils, the cold mir may be brought in
at or near the floor level and passed
through the hot-water coils-the outlet
for vitiated air being in or near the cell
ing-to heated up cast fue. In larger
rooms or buildings for public assemblies
it may be necessary with either of these
systems TO use a fan, either to propel
fresh air into the room or to draw away
the vitiated air.
The great desideratum in the admis-
sion of fresh air is to cut il up into very
fine-streams, something in the way water
is cut up in passing through the fine nose
of q watering-can. 1t has been found
that air admitted through tube or ORR
fee of equal sectional area throughout
enters rs u cold draught; but if the in
let be through a series of small truncated
cones, the smaller section outward, the
larger inward, with q wire gauze on the
inside, the current is so cut up and lf-
fused that the draught is not felt. BY
analogy, mass of water entering
through narrow canal drives all before
it and cuts channel for itself. but the
same quantity passing over large sur
face of ground gently irrigates it. An
other important point is not to let the
passage of the air be at too great
velocity; the gentler the flow the better.
