thority that if the cost can be reduced
to six cents a pound the demand il
Germany alone will exceed $500 tons
annually.
In fact, many substances have beer
taken out of the electric furnace which
have heretofore been found only in ma
ture. Siiichromite is obtained from q
mixture of natural chronic iron, sand
and carbon. 1t is an abrasive material
of good use in the arts. Ammonia and
! nitrideS have been obtained from the
furnace as follows: Oxygen, compounds
/ of such elements as boron, silicon,
magnesium, titanium and vandanium,
capable of combining with nitrogen at
a high temperature, are exposed to the
heat of an electric furnace in the pres
ence of free nitrogen and carbon A jet
of sand is blown in while generator
/ gas is introduced. On entering the hot
zone of the furnace the sand evapo-
rates and the nitrideS so formed are
treated with steam to obtain ammonia.
Moissan made veritable diamonds in
the electric furnace, and we have it on
the authority of Professor Dolbear that
worthless fragments of. rubies and
emeralds are easily fused together into
a large and precious gem by the same
means. The latest report concerning
the furnace is that uranium can be
produced from it. The electric temper
ing process now in vogue are some
what in the same line and they gain
interest when it is pointed out that the
tests of the old Damascus blades and
electrically tempered blades show the
latter to equal the former in nearly
every respect. Electric arc welding is
also in the same category, and it is
now practiced on a commercial basis

PRESERVING MEAT AND REFRIG-
GRATING BY ELECTRICITY.
Reinke has proven that turbid beer
can be fined to a brilliant condition by
suspending electric lamps in the fer
menting vessels. The light brings about
a much quicker and better clari6ca-
ton, the yeasty matters being rapidly
deposited together with the reSinous,
albuminous and glutinous substances
which are always present. 1t is not
the effect of temperature. Wines and
whisky can be aged by passing an
electric current through them, and a
patent for one process of the kind has |
already been issued. The fermentation !
of cider can be arrested electrically, !

after which the meat is dried. But IN
the memoirs of Andrew Cross, pub
Iished in 1857, that eXperimenter claims
to have kept electrically treated fish /
fresh for three months, although they
were tasteless at the end of that pc
rod. 1t is possible, however, to refrig-
crate by electricity, water having been
frozen at a certain junction of a Their

SUGAR AND MOLAS-
SEES BY ELECTRIC CURRENTS
The Russians have been very active
n applying electrical methods to sugar
1t seems that the current
tets on certain materials in the liquid
which are not sugar with more force
han lime, deDositing three times as
much of the heterogeneous materials as
he lime. The Schollmeyer and Huber
process is now used industriallv in
and in Woronowitza in ;
Russia. The Germans, on the other !
and, have sought to electrolize mo- I
rofit in sugar factories by improving s
he quality of the bi-Droduct The ex- ]

acting sugar from cornstalks has h
