SCIENTIFIC NOTES.

SCIENTIFIC MOTIFS
To fill holes in burrstones, use melted alum
mixed with burrstone pulverized to the size
of grains OF sand
Faraday established the fact that gases are
but the vapors of liquids possessing very
low boiling point.
The supply of air without draught is more
important than the size Of the room; still, a
large sleeping room, well ventilated, is most
desirable, and children should never be tucked
away in small unyentilated rooms.
CANDLE-wICK GAs.-The composition OF
this smoke is carburetted hydrogen, carbonlc
oxide, burnt olein, etc. When putting out a
candle light before going to bed, always do 1t
SO that there shall be no burning wick left to
poison the air Of the room.
SMALL SLEEPING RooMs.-A large sleeping
room is but little better than small one, I'M
less there is a supply OF fresh air for 1t, and
egress for spoiled air; and, on the other hand,
small room, where there is a constant
change of air, is nearly as good as large
one.
BAKED AIR When the air is passed
through a hot furnace and heated to high
degree, and then passed into room, such
air should be called baked air, and 1t Is about
Nothing bat headache faintness, droWslness
and dizziness can come from its use.
When we heat our houses and close them
from outside air, the heat turns the mixture
into vile mess unfit tor breathing. The only
remedy is vantiation. Now that it is cold
weather and our rooms are closed from free
currents of outside air, let us look after the
matter thoroughly and do our best to prevent
injury to ourselves from polluted air.
Corn-fed hens do not lay in winter, for the
simple reason there is no albumen material
in the corn. When wheat is given to them,
there is fat enough in it to supply all that IS
needed for the yolk, and albumen enough to
make the white, and lime enough to furnish
the shell; it does not thus seem difficult to
understand why could-fed hens should not
lay, as they do not, and why wheat-fed hens
should lay, as they do.
COUNTERFEIT GRAHAM FLoUR-Nearly all
the Graham -four sold in New York, and
perhaps in other large cities, IS bogus. l. is
made by mixing the coarse5t OF the bran
with either spoiled flour or with white flour
which NAV not be spoiled The flour is made
into bread by bakers and sold to dyspeptics,
who think it wholesome but it is poor sub
stitute for the genuine article. Those who
want a genuine article must either make II
with a home mill, or have IL made to order by
an honest miller.
THE ENGLISH EIGHTY-oNE Ton Gun
misunderstanding to the hot1iScde Ieltufg
Krupp is making preparations for the con-
struction of l24-ton cannon. This enor
nous gun will throw steel bolts weighing
more than 2200 ID each, AMI will require q
load of powder weighing 400 lb. 1t is est
mated that the projectile will pierce at dis
lance of 5000 feet the heaviest plates, OF ~
inches thickness, now used on the English
ironcads and that its extreme range will ex.
coed seven miles and a half.
A MICROSCOPIC BI-CESTENNIAL The city
Of Delft, Holland, has recently celebrated the
b-centennal anniversary of the discovery o.
microscopic infusoria by Antony Van Leeuw
enhoek Public memorial services were held
a monument unveiled, a banquet partaken Of
and the discoverer's instruments displayed
1t is something new to witness people OF al
classes in city taking part in an enthusiastic
celebration of a discovery made two hundred
years ago, and regarding which the average
individual knows SO little.
CURE FOR LOVE OF LIQUOR At festival a
a retormatory institution, recently, gentle
man said, of the cure of the use OF intoxicat
ing drinks: " overeame the appetite by
recipe given to me by old DIR. Hatfield, one 0
those good old physicians who do not have

prescription is simply an orange every morn

liquor nor medicine. | have done SO regu
larly, and find that liquor has become repul
sive. The taste of the orange is the saliva Q
my tongue, and it would be as we'll to mi!
water with oil as rum with my taste.
TREATMENT OF SORE THROAT In case o
ordinary sore throat, the simplest and hes
treatment is the wet pack, using linen cloti
wrung from cold water, and over this knl
or crocheted yard band, four feet long an
four inches wide. Apply this two or thre
nights in succession unless it is a very seriou
case, when the pack should be kept on dur
ing the day. If taken eff in the morning
wash the throat in very cold water, and ru
drv with coarse towel and with the hand
This will prevent taking more cold. Tn
more friction used the better; let it be sol
of squeezing of the parts, SO as to affect tn
deep-seated tissues. Sore throats may b
prevented by these means from becomin
chronic.
In these DAYS of claimant demand fc
women's work surely the opening here show
by the Lancet should be gladly taken advan
tage of. 1t is eminently woman's work {
nurse the sick and cheer the sufferer; an
if it is true that half of the happiness of mar
kind depends upon how the daily meals ar
caoked, it is still more so of the sick chambe
where daylight brings little JOY and night u
