POPULAR SCIENCE NOTES.


German doctors have independently ar
rived at the conclusion that most persons
struck by lightning, and 10 all appear
ance dead, could be recalled To life by
applying the method of artificial respira-
ticn in use for resuscitating the drowned.
This method proved successful in the
case of trumpeter who was apparently
killed at Berlin in 1891.
The STRENGTH or IcE.-Thc necess-
ties of war have not unfreQuently led To
valuable discoveries of a 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, il begins
TO bear the weight OF man who is
marching alone. At thickness of some.
thing over three and one-half inches it
will bear files of infantry. When ii has
become twelve centimeters, or nearly
four and three quarter inches thick. 1t
sustains light artillery or carriages, and
at twenty. nine centimeters, or about
eleven and four -tenths inches, IL 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 IL
should be remarked that they apply only
TO young ice. SUGGESTIONS of colder and
warmer weather, in the course of n few
weeks, produce change in the structure
of ice which greatly weakens its power
of resistance to pressure. Accordingly,
AZ A,.I Aaet ,atn tUa IN
above should not be trusted in the case
OF ice that is not of recent formation.
THE SIZE OF THE SKA. gallon OF
water weighs ten pounds, so the number
of gallons in the Pacific is over 300 ril-
lions, an amount which would take more
than million years to pass over the
Falls of Niagara. Yet, put into sphere.
the whole of tho Pacific would only
measure 726 miles across,
The Atlantic could be contained bodily
in the Pacific nearly three times. The
number of cubic feet is III followed by
seventeen ciphers; a number that would
be ticked oil by our million clocks in
$40, 900 years. Its weight is 325, 900
billion tons, and the number of gallons
in il is 73 trillions. Asphere to hold tho
Atlantic would have TO be 533 12 miles
in diameter. Ii il were made to fill a
circular pipe reaching from the earth to
the sun-a distance OF $4,000, 900 miles
the diameter OF the pipe would be | S37
Yards, or rather over mile; while pipe
of similar length to contain tho Pacific
would be over mile and three quarters
across. Yet the distance to the sun Is

child were born with an arm long
enough to reach tho sun 1t would not live
long enough TO know that IL had touched
il, 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
ccntcnarian.
The rest OF the sea includes the Ind
ian Ocean, the Arctic and Antarctic
Seas, and various smaller masses OK
water. IL covers nm area OF AZ, 000, 900
square miles and would form circle Of
! 1900 miles in diameter. The average
depth may be put at 1900 fathoms

| 900 cubic miles. IL weighs 800, 900 bill
lion tons, and contains S7t trillion gal
! Ions, while IL would form column
reaching TO the sun OF 1000 yards in
diameter. II 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 40, 900, 900 square miles
could be confined by circle Of 10, $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 dianeters Of
which are In the proportion 10 one an
other of 1853, 1873, 90 and 62 respectively; {;
or by a crown for the surface OF the
earth, n half lf-crown for the surface OF the
whols sea. shilling for the surface OF
the Pacific, three.penny piece for the
surface Of the Atlantic.
Supposing the sea to be formed into a
round column reaching TO the sun, the
diameter Of the column would be nearly
two and half miles. The Pacific would
form 53, 900, 900 miles Of it's total
length Of 80, 900, 600, and the Atlantic
100000
II il were column OF ice, and the en-
tire heat OF the sun could be concen-
trated upon it, 1t would oil be 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.
