SCIENCE AND INDUSTRY.

-Gnomium is the name given to the
new metal discovered in commercial
nickel and cobalt.
1t is supposed that the steam power
now utilized is almost equivalent to
the hand labor of the whole population
of the world.
Experiments in Welding wire rope
by the electric process show that the
strength of the finished welding is
within eighteen per cent. OF the normal
strength OF the cable.
Aluminium for dental purposes is
said to be coming into favor. It is pro-
nounced better than rubber and less In
cost than gold. 1t is bright, strong,
odorless, and as healthy to the gums as
gold or platinum.
-Recent experiments at the Ear
Hospital in London indicate that stam-
mering is not nervous defect only.
In operations for deafness in several
cases the patients were cured of stam-
mering also, and the result is the
opinion that stammering comes from
some defect in the hearing.
IN. Beauregard, an eminent Egypt
ologist, believes that Egypt at the time
OF the Pharaohs exhibited the mixed
condition Of combining the use of flint
implements with acquaintance with the
means OF extracting copper and blend
ing it with other metals.
Why is negro's skull harder and
thicker than white mans? Herodo-
tus explained it by attributing it to the
early exposure Of African children to
the heat of the sun; and Prof. Virchow,
after his trip up the Nile, sides with
the Greek historian.
Satisfactory tests have been made
OF the new liquid, pyrodene, which
renders wood, textile fabrics, and such
inaammable materials fireproof The
liquid. which is an English invention, is
made of all colors, so as to be used rs
a substitute for paint, and is claimed
to render houses entirely freproof.
Doors are now made OF two thick
paper boards nodded into panels and
glazed together with glue and potash,
and put through heavy rolling pro-
cess. Covered with waterproof coat
ing, they are hung like wooden doors,
and are both beautiful and serviceable.
Investigation has shown that terra
Gotta bricks and blocks best resist the
action of fire. Next to these as fire.
resisting materials come concretes.
For buildings intended to be fire
proof, the best materials are iron work
encased in terraccotta, with tile or
brick work in roof and floor.
The arch@ologists of Norway have
pursued researches into the early pop
ulation Of the country as far north as
20 degrees Is minutes. The results
show large population in prehistoric
times, but one not given to agriculture.
No bronze objects are found, and the
conclusion Is reached that the men of
the early iron age were the first to
affect them, those Of the bronze age
never having reached the northern
parts.
An interesting fact is that one Of
the greatest problems now perplexing
scientific men-the production of heat
less light-has been already solved by
nature. The light from luminous
beetle sufficient for reading a news
paper-is shown by the spectroscope to
be all of one kind, and just the kind
for seeing, while the thermopile finds
no evidence Of heat. Yet in all our
artificial lights vast quantities Of fuel
are wasted for useless heat.
"A French chemist named Beaumeta
exhibited at recent meeting of the
Paris Academy of Medicine a new
substance which he names
fromentine. It is obtained from wheat
by the aid of special millstones and is
really the embryo of the wheat reduced
to -four. 1t contains three times more
substance than meat, and
a large proportion of sugar. It is
thought that it may advantageously
replace powdered meat as a concens
trated food. 1t may be employed for
soups, and even for MAKING
biscuits.
