to serve the same purpose cheaper.
"A society has been founded in Paris
for the scientific study of the mouth
and it's accessories in their various
affections.
"A new method of deadening floors
is to fill the space beneath a floor and
the ceiling below with shavings made
incombustible by saturating them in
thick whitewash. 1t is said that this
shuts out the sound more effectually
than cement.
1t has been calculated by Prof.
Rogers, of Washington, that the dynam-
ic power of single pound of good
steam coal is equivalent to a mans
work for one day; three ton, for twenty
years, and one square mile of a seam OF
coal only four feet thick will represent
the labor of million men for twenty
years.
A new candle has been brought out
which extinguishes itself in an hour.
This it does by means of a tiny extin-
guisher of tin, which is fastened in the
wax by wires and which effectually
performs its task. 1t is only necessary
to remove this diminutive extinguisher
when its work is done, and the candle
is again ready to burn another hour.
The scientific authorities in Europe
seem to have decided that horse-fesh
is inferior to beef as an article of diet.
The question was long ago settled in
the same way by the common practice
alike of civilized and savage races,
| who have found that the flesh of the
well-fed and soft-muscied OK is far less
| likely to resist the work of digestion
and assimilation than the tough and
stringy fibers of the horse.
"A plan has been contrived for gen.
Grating steam for motive power at the
smelters, through the use of Stag, the
latter being dumped into large, shallow
vessels, which are afterward run under
ing steam. In some experimental tests
of this new method it was found
capable of maintaining as much as
seventy-fve pounds pressure on a
vertical boiler for seven days, thus in
suring great economy.
In lecture on Foods recently
given in London by DR.. B. w. Richard
son, the lecturer said: ''There is an
other very excellent food now becom-
ing common, viz, the banana. This is
one of the best of foods, contains IA
per cent. water, 20 per cent. fuel,
per cent. fesh-formers, and OF per
cent. mineral. Comparing these figures
with those furnished by milk, namely,
sc per cent. water, per cent. fuel
per cent. fesh-formers, and or per
cent. mineral, we might almost look
upon the banana as condensed milk.
According to Professor Sergeant,
the strongest wood in the United States
is that of the nutmeg hickory of the
Arkansas region, and the weakest the
West Indian birch The most elastic
is the tamarack, the white or shell.
bark hickory standing far below it.
The least elastic, and the lowest ir
specific gravity, is the wood of the ficus
aurea. The highest specific gravity
upon which in general depends value
as fuel, is attained by the bluewood O
Texas.
Small white globules of porcelain
are made in Munich. They are made
to take the place of ordinary lead sho
used for cleaning wine and medicine
bottles, as porcelain is entirely fre'
rom the objection of producing leat
contamination, which is often the resul
when ordinary shot is used. Thei
hardness and rough surface producing
when shaken, greater friction, adap
the porcelain shot well for quickl,
cleaning dirty and greasy bottles, ant
, they are not acted upon by acids o
alkalies; almost any liquid can be used
