The oxalate of cereum is said 10 be an
efficient palliative for nausea in seasicl,ness
The doses are from ten to twenty grains
every two or three hours.
Waste silk has been shown 10 be tho mos,
effective non-conductiye covering for steam
pipes. The price is high, but the demand is
very great
new material called "lca;herner is an
English manufacture IL can be sold for 9
or cents per pound is said to he as tough as
leather, and is destined for packing and BAG
gins.
y new patent candlestich keeps the candle
perpendicular, no matter how the stick NAV
be held. The main principle of thu invention
] Is a ball joint of the simplest kind at the bot

an arm from the side of the base ana extend
/ ing TO the center. The comfort and safety
OF the contrivance is apparent
; \ new target, which indicates the value Of
the last shot without the necessity Of a
marker, has been brought out. When the
shot strikes II colored disc appears, which
tells the value by is color. The target has
been tried successfully at indoor practice,
and 1t is hoped that n trial at long ranges
will he afforded the inventor
An instrument called the osteotomc has
been invented as an Improvement over tho
tedious and clumsy surgical method OF cut
ting through bones by means OF saws and
chisels. 1t is practically a circular saw re-
VOWED at very high speed by an electric !
motor Al ingeniously devised shield. |
which passes around the bone TO be ope- |
rated upon, protects the surrounding flesh J
from injury.
A lamp burner has been patented by Mr.. |
Arthur Cautius, Of Berlin, Germany The |
WICK tube consists Of two concentric tubes
with space between them for the wick, the
inner tube being shorter and the outer one
longer and provided with fiange, covering
the top of the wick, the burning portion Of |
which will be on the inside instead of the
top, between the flango and the top OF the

At the Royal powder factory, Of Wetterer.
in Belgium, new gunpowder is being made.
They call it poudre papier, or paper powder,
and it is said that n charge of 2l< grammes
60 grains gives, in rifle of small caliber,
gn initial velocity Of GEO yards to the bail.
This is equal 10, if it does not beat, the Letrl
powder. The additional advantages are at
tributed to it OF not smearing the barrel, Of
producing no smoke and OF causing little re-
coil.
The following method OF expelling mus
lutoes from room is given by The Scien-
life American Take OF gum camphor O
piece about one-third the size Of q hens egg
md evaporate it by placing it in tin yes
el and holding it over lamp, taking care
hat it does not ignite. The smoke will soon
i'll the room and expel the mosquitoes, and, {
wen though the windows should be left open
III night, they will not enter the room as |
ong as the odor remains. .
