ing the evil eHectSl OF the night air,
about which a word must be said.
In her admirable writings on hygiene
and the management Of the sick, Miss
Nightingale has done much to correct
this mistake. Is was formerly the
universal belief that the night air was
very injurious. But the fact is, that,
except under certain circumstances,
it is as healthful, or even more SO,
than that Of the day time. The
night air Of large cities, such as Lon
don, when the hustle and connection,
which cause it to be loaded with dust
particles, is comparatively quelled,
and the numerous fires which contain
mate it with their smoke are mostly
extinguished, is purer than that Of
the day. Nothing conduces more
to healthy sleep than good ventila7
ton, and no mode of ventilation SUR
passes that obtained by opening q
q window at the top, by which the
influence Of. draft is avoided, while
the upper stratum Of air, to. which
impurities ascend, is constantly re-
newed. But there is. still another
reason for at times adopting night,
even in preference to day, ventilation,
In. sultry weather it is common mis-
take to open the windows instead of
keeping them altogether closed, as is
the case in very hot climates. But
little reflection will show that since
the, height of the thermometer in the
sun always greatly exceeds that
shown at the same time by another
thermometer placed in the shade, by,
opening the window we admit air
much heated into our rooms. The
proper time, under such oircumstan-
ces, for ventilation, is dnring the
night, when the external atmosphere
is cooled down. By adopting this
plan in hot weather, the temperature
of the room may always be kept
down several degrees lower than if
the opposite course is Z pursued

To THE NoRTH POLE BY BALLOON.
OF this new venture the PAIL
MALL GAZETTE says: ''The inyaria
BILE failure which has hitherto attend
ed nautical expeditions to the Arctic
regions has induced two Frenchmen,
l.Messieurs Tissander and de Fou-
vielle, to undertake the enterprise Of
reaching the north pole in a balloon.
The machine in which the bold. adj
venturers are about to embark on
their perilous journey, and which is
appropriately named lie Pole Nord, 4
IS now being completed in the Champ
de Marsgwhich the government has
placed at their disposal for the pur-
pose. The monster balloon, beside
which even the famous 'Geant' would
seem mere toy, will contain over
ten thousand cubic metres of gas, and
is composed entirely Of a cloth man-
ufactured from caoutchouc, which
will allow of great expansion in the
rarifed strata Of the atmosphere.
The seams uniting the different pieces
form totalalengtho Of three English
miles. The car, marvel, it is said,
of strength and lightness, is con-
structed to carry ten passengers, four
thousand pounds ofbatlast,. and pro-
visions for a month. 1A~'N A~N ~
