Plaster of paris is being driven out
If Paris by wood pulp, which is made
to serve the same purpose cheaper.
A society has been founded in Paris
for the scientific study Of the mouth
and its accessories in their various
affections.
A new method of deadening floors
is to fill the space beneath a floor and
the ceiling below with shaving5 made
incombustible by saturating them in
thick whitewash. It is said that this
shuts out the sound more edectualiy
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 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 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 authoritiesin 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-musc.ed OK is far less
likely to resist the work OF dige stion
and assimilation than the tough and
stringy fibers of the horse.
IA plan has been contrived for gem
Grating steam for motive power at the
shelters, through the use of Stag, the
latter being dumped into large, shallow
vessels, which are afterward run under
boilers and the heat used in general
| ing steam. In some experimental tests
of this new method it was found
capable of maintaining as much as
seventy-fve pounds pressure on
vertical boiler for seven days, thus in
surfing great economy.
I'm lecture on Foods" recently
given in London by DR.. B. w. Richard
son, the lecturer said: There is an
other very excellent food now bscom-
ing common. viz, the banana This is
one of the best of foods, contains "a
per cent. water, 20 per cent. fuel, 5
per cent. fesh-formers, and or per
cent. mineral. Comparing these figures
with those furnished by milk, namely,
Sc per cent. water, 9 per cent. fuel
per cent. fiesh-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
i West Indian birch. The most elastic
is the tamarack, the white or she'll
bark hickory standing far below IT.
The least elastic, and the lowest in
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 Of
Texas.
| Small white globules Of porcelain
are made in Munich. They are made
to take the place Of ordinary lead shot
used for cleaning wine and medicine
bottles, as porcelain is entirely free
from the objection of producing lead
contamination, which is often the result
when ordinary shot is used. Their
hardness and rough surface producing,
when shaken, greater friction, adapt
the porcelain shot well for quickly
cleaning dirty and greasy bottles, and
they are not acted upon by acids or
alkalies; almost any liquid can be used.
