SCIENCE AND INDUSTRY.

DR.. Bauer, an Erfurt chemist, is said
to have sold to Paris perfumer for
$4,000 a patent for making artificial
musk.
"A new and valuable fiber is said to
have been found in the stalk of the okra
plant, of which two crops per year can
be raised in Florida. 1t is said to be
superior to jute or Sisal hemp.
Nearly all foreign navies are using
electric-lighting devices of American
origin, and no vessels, so far as known,
have yet been provided with installa-
tions superior to those equipped by the
United States Government, either in
perfection of design or quality of work
manship.
"A new sort of boot sole has been in
troduced in Nuremburg, consisting of
sort of trellis of spiral metal wire,
the interstices being filed with gutta
percha and resin. They can be fitted
with nails like ordinary soles, are fifty
per cent. cheaper than leather, and
vastly more durable.
In experiments made in France,
where plates of celluloid were used for
sheathing ships bottoms instead of cop
per, it was found that the plates were
intact and free from marine growth,
which was abundant on parts not pro-
tected by the celluloid.
The Deutsche Fischerei Zeitung is
shown to be wrong in saying that the
device Of packing fish in ice for trans
portation in hot weather was first used
n mn In n 4 s.,
Nuremberg in 1880, Erasmus Franciscus
refers to it as Chinese custom, and
recommends its adoption in Europe, but
1t was left for Yankee to reintroduce
the practice nearly tive centuries later.
An electrical instrument has been
invented which is designed to remove
the pain incidental to the extraction of
teeth. 1t consists of adjustable pivot
ally-connected prongs carrying buttons
and connected with an electric battery,
the buttons being placed on the face
over the nerves leading from the teeth
to the brain, and a circuit established
the moment the tooth-extraeting instru-
ment touches the tooth to be removed.
Paint from potatoes is a new wrin-
kle in the arts and sciences. KuhIow's
Trade Review gives the manner of prep
aration. Boil kilo of peeled potatoes
in water; after MASKING, dilute with
water and pass through fine sieve.
Add two kilos of Spanish white diluted
with four kilos of water, and the result
will be color of beautiful milk white
Different colors can be effected by the
addition of different ochres or minerals.
Apply with a brush; it adheres to plas-
ter and wood very well. will not peel,
and hest of all is cheap.
A great many people seem to be
laboripg under the impression chat a
trip in the electric cars during storm
accompanied by lightning is exceeding
dangerous. Such, however, is not the
case, for so excellent are the precau-
SiOns taken to insure that the discharge
is conducted to the ground that no harm
can result. Each car is provided with
lightning arresters, which protect the
apparatus from all damage, and abso-
lutely insure the safety of the passen-
gers.-Electrical Review.
"A French inventor by chemical
process prepares si1k-like fabric from
cellulose, out of which fabrics are woven
that closely resembly silk. Specimens
of the new fabric were recently ex-
hibited to the members of the Silk As
sociation of America. They found that
it would take twice the quantity of the
artificial fabric by weight to produce a
given quantity of cloth that it would of
pure silk, that it would not be as strong
as silk by about one-third, and that it
almost entirely lacked the elasticity of
silk. 1t resembled silk in appearance,
but that was all. It's relative cos5 or
cheapness as compared with silk ha, not
yet been demonstrated. It is hardly
probable that anything will be found to
take the place of the silk-worm's throad.
