SCIENCE AND INDUSTRY.

The application of hydraulic power
to the manufacture of steel seamless
boats is one of the latest things in En-
gland. These boats are thought to be in
every particular superior to those made
of wood, and can be made at about the
same cost.
Engineers use kerosene to remove
the scales which form on the inside of
boilers. The oil is poured into an
empty boiler and the water then turned
on. The oil, floating on the water, then
comes in contact with the scales before
the water does.
Tho system of sinking shafts
through qnicksand and other water
bearing strata by freezing the soil with
brine cooled by refrigerating machines
is a practical success. The freezing ex-
tends thirteen feet each side Of the ver-
tical pipes which are driven down to
carry the fluid, and the frozen material
works like soft sandstone.
Physicians in Italy, ETC., believe
malaria to consist of fungus floating in
likely to enter the system in much
larger quantities through the water
drank, than through the air breathed.
Hence. in malarious districts all drink
ing water should be boiled and then fl
tered.
Compound locomotives are to be the

in a French village of about 400 in
habitants, eleven of the seventy-four
deaths in eight years were from cancer.
DR.. Arnaudet finds that six of the cases
of cancer were in a single neighborhood,
among persons who used as a beverage
cider diluted with dark-colored water
from the swampy ground, and that in
five of the victims the disease attacked
the stomach. These facts are given in
| support of the view that cancer is con.
tagious, the swampy water seeming to
have served as carrier of the contagion.
"A chemist of Bockemheim, Ger.
many, has discovered new alloy
which is said to resist the attack of most
acid and alkaline solutions. 1t contains
Is parts of copper, 2.34 parts of tin, 1.S2
parts of lead and one part of antimony
being, in fact, bronze with the addi
ton of little lead and antimony. Il
is claimed that the alloy is much better
than ebonite vulcanite or porcelain FOL
vessels or fittings liable to be acted
upon by chemicals.
Considering all the achievements o.
science on this globe and among tb'
celestial spheres, it seems strange tina
there is part of this earth not yet ex
plored. In other words, we have
weighed the planets and marked thelI
orbits, but we are unable to make maj
of the world. 1t is idle to imagine tina
Arctic exploration will be abandoned
The quest for the North Pole will 60 OF
to the end of time, if not crowned will
success.
"A very simple apparatus for obtain
ing an electric spark is made by Ger
man physicist. Round the center of ;
, common lamp chimney is pasted stril
of tin foil, and another strip from on
end of the chimney to within quartz
inch of this ring. Then a piece ofsill
is wrapped around brush, and the in
terror of the chimney is rubbed briskly
In the dark bright electric spark ma,
be seen to pass from one piece of tin fol
to the other each time the brush is with
drawn from the chimney. Many othe
experiments can be tried with this az
. paratus.
