Leather is being made waterproof by
new and cheap process in Massachusetts,.
A steel car-wheel is expected to run
80, 900 miles. but very few of them ever
make that distance.
Science has not explained why base
ball tn own by pitcher curves in SO
many different ways.
English chemists have made the in
teresting discovery that ilourine will
dissolve metal of any Sort even gold.
Tin-ware Is made of sheets of iron
covered with thin coating of tin, by
dipping them into melted tin. Bride
BITS, small nails, etc., are timed in the
same way.
Railways are said to consume more
than half of the worlds production OF
iron, the 10, 600, 00) car wheels required
in the United States alone taking more
than 1000, 900 tons.
The average age of all the people in
France is given US thirty-two years two
months and fifteen days The average
in the United States is only twenty-four
years ten months and twenty-four days.
1t has been asserted that the rotation
of the wind in cyclone is always from
hight to left, or against the hands of
clock, in the Northern Hemisphere, while
the rotation is directly opposite in the
Southern.
scientist has discovered curious
regularity in the geographical distribu-
ton of certain virtues and vices. In
temperance is found north of the forty
eighth parallel amatory alterations
south of the forty-tifth; financial ex-
travagance in large seaports; thrift in
pastoral highland regions.
A series of experiments lately made by
q French machinist are said to have
proved that steel loset weight by rust
twice rs rapidly as cast iron when ex
posed to most air. Acidulated water
was found to dissolve cast iron much
more rapidly than steel From this it
, would seem that steel bridges ar less af-
fected by the acids contained in the
smoke OF the locomotives than are iron
, ones.
The attention of the French Academy
, of Sciences has been drawn by M. Faye,
t the EN- nent astronomer, to the apparent
$ terrestrial crust goes on more rapidly
under the sea than with land surface.
e From this he argues that the crust must
- thicken under oceans at more rapid
!, rate, so as to give rise to a swelling up
e and distortion of the thinner portions of
e the crust; in other words, to the forma-
n ton of mountain chains.
e 1t has generally been believed that the
n reduction in average height of French
e soldiers which followed Napoleon's wars,
/ due, of course, to the immense slaughter
e in those campaigns, made all of those
S soldiers the shortest in Europe. But,
e according to high medical and mill
5 tary authority in Russia, the minimum
height of the Russian and the French
: conscript is about equal--ive feet; while
: in most other European countries the
s minimum ranges from five feet one inch
to five feet three inches.
. Thr Spanish correspondent of the
= Porgres Mittdtre reports that General
. Pando, who has been experimenting for
= some time, has invented new projectile,
y which will probably be applicable to
= guns up to twenty four centimetres.
- The principle of the new shells depends
- upon the reaction of two substances, both
= liquid, or one liquid and the other
- solid, which, separated, are harmless,
y but which, being brought together by
;. the shock of the projectile striking any
. object, cause violent explosion. AL
: though General Pando keeps the nature
y of his explosive secret, several substances
- are known which act in the manner de-
