In looking through an EGG at candle,
il will be found that the light will get
more and more faint rs the egg gets

Doctor Corhcld says that it is not a
good plan to eat much of cheese that
has been allowed TO reach an advanced
stage of decomposition, as poisonous
effects have resulted from eating cheese
in that state.
NJ Clcmandot uses fine glass wool
for diil'uSing the electric beam instead
of ground or opal glass, The glass
wool, which is very fine, is placed in
tubes; and the latter are united at their
sides rs to form lantern, conical in
shape, with the taper downwardS
The tubes are closed ut the top and
bottom to exclude dust, and ii is found
that only about fifteen per cent, OF the
light is absorbed. The opacity can
however be increased by inserting more
WOOL and the light can be easily
colored if desired.
Utilization of old Steel new pro-
cess of using up old steel has been late
" patented. The resultant metal is
said to possess extraordinary strength
and ductIity. The process consists of
mixing up old steel with apatent com
pound and Subiccting the whole to a
flrnace-heat when the particles ANAL
gamate, Steel made on this plan has
been turned out at the llunsIet Works
and sold readily for fi5 per ton. The
process is said to be second only in
importance TO Besscmer's invention,
and il will be especially valuable as
finding use for old BesScmer steel rail.
The Indestructiblily Of Matter. This
is capable of ready demonstration by
preparing n couple of glass tubes Of
equal weight, each being filled with
pure oxygen and containing Il few par
ticles Of carbon, free from appreciabe
amount OF ash-that prepared from the
fine loaf-Sugar gives very good results.
The tubes are of precisely equal weight
and are Theoretically sealed. BY heat
ing one of them the charcoal is caused
to burn and ultimately TO disappears
the tube contents however is of course
found still TO balance the other tube,
which has not been heated, rs it is of
preciSeI the same weight ~ il was at
first
