POPULAR SCIENCE NOTES:

A REMARKABLE DISCOVERY
German doctors have Independently ar
rived at the conclusion that most persons
struck by lightning, and to all appear
ance dead, could be recalled to life BY
applying the method of artificial respira-
ton in use for resuscitating the drowned.
This method proved successful IN the
case of a trumpeter who was apparently
killed at Berlin in 1891.
THE STRENGTH OF Ice. The necessi-
ties of war have not unfrequently led to
valuable discoveries of practical scien-
tific character. OF late the French Min
lister of War has been studying the sub
ject of ice from the point of view OF its
capacity to maintain weights. He has
found that when ice has become about
an inch and three-fifths thick, it begins
to bear the weight of man who is
marching alone. At thickness of some
thing over three and one-half inches 1T
will bear files of infantry. When 1T has
become twelve centimeters, or nearly
four and three quarter inches thick. It
sustains light artillery or carriages, ana
at twenty nine centimeters, or shout
eleven and four tenths inches, it bears
the heaviest weight that the transporting
Of an army requires. These conclusions
Of the French military authorities may
have some interest for skaters, but IT
should be remarked that they apply only
to Young ice SUGGESTIONS of colder and
warmer weather, in the course OF a few
weeks, produce change in the structure
of ice which greatly weakens its power
of resistance to pressure. Accordingly,
the measurements and estimates given
above should not be trusted in the case
Of ice that is not Of recent formation.
THE SIZE OF THE SEA.--One gallep OF
water weighs ten pounds, so the humDG
of gallons in the Pacific is over 200 trils
lions, an amount which would take moro
than a million years to pass over the
Fails of Niagara. Yet, put into sphere.
the whole of the Pacific would only
measure 1875 miles across.
The Atlantic could be contained bodily
in the Pacific nearly three times. The
number of cubic feet is 1T followed by
seventeen ciphers; number that would
be licked off by our million clocks iD
100000 years. Its weight is 1928, 900
billion tons, and the number of gallons
in it is 10 trillions. Asphere to hold tho
Atlantic would have to be 533 12 miles
in diameter. Ii it were made to fill
circular pipe reaching from the earth to
the sun--a distance of 90, 100000 miles
the diameter Of the pipe would be ], o3s
yards, or rather over annie; while pipe
of similar length to contain the Pacific
would be over mile and three quarters
across. Yet the distance to the sun is
SO great that, as has been pointed out, it
child we're born with an arm long
enough to reach the sun it would not live
long enough to know that it had touched
it, for sensation passes along our nerves
at the rate Of 100 feet second, and to
travel from the sun to the earth at that
rate would take century and a-half, and
such an abnormal infant is an unlikely
centenarian.
The rest of the sea includes the Ind.
ian Ocean, the Arctic and Antarctic
Seas, and various smaller masses OF
water. 1t covers an area of 100000
square miles and would form a circle Of
1900 miles in diameter. The average
depth may be put at 1000 fathoms
$4,000 feet, and the contents at 95, 000,-
900 cubic miles. 1t weighs $50, 900 bill
lion tons, and contains S7t trillion gal
Ions, while it would form column
reaching to the sun of 1000 yards in
diameter. If we now combine into one
vast whole these various figures we ar
rive at some stupendous results in answer
to the question, "How big is the sea 2"
The area of lac, 100000 square miles
could be confined by a circle of 13, $50
miles across The relative size of the
areas of the surface of the earth, of the
whole sea, the Pacific and Atlantic, are
represented by circles the diameters of
which are in the proportion to one an
other Of 1873, 1873, SO and so respectively;
or by crown for the surface of the
earth, half-crow for the surface of the
whole sea, shilling for the surface OF
the Pacific, a three penny piece for the
surface of the Atlantic.
Surprising the sea to be formed into
round column reaching to the sun, the
diameter of the column would be nearly
two and half miles, The Pacific would
form SO, 0O0 600 miles of its total
length Of $4,000, 900, and the Atlantic
1S.O00,OON
If it were column Of ice, and the en-
tire heat of the sun could be concen-
trated upon it, it would all he melted in
one second, and converted into steam in
eight seconds, which illustrates the heat
OF the sun rather than the size Of the
sea. Cincinnati Commercial Gazette.
