POPULAR SCIENCE NOTES.


The late Leonard Case Of Cleveland, left |
for a school Of applied science, property |
valued at 81, 100000.
An electric locomotive has been manu-
factored and successfully operated on the
street railway Of Berlin.
For use in telegraphy, aluminium is said
to possess double the conducting power Of
iron, and can be made into extremely thin
wires.
The longest submarine cable in the
world, is that along the east coast Of Africa
from Mattel 10 Alden, 1t being 1000 miles
length
A railway has Just been finished for the
ascent OF Mount Vesnvius. II is 900 met
ers in length, and will enable tourists TO
ascend by 1t to the crater In safety.
The deepest well in the world is the one
recently finished at Buda Pesth, Hungary,
being 5000 feet in debth. The tempera-
ture OF the water it yields is nearly 1855 de-
grees Fahr.
The very bright star now to be seen near
] the horizon, about due south, is "Sirius"
| the dog star, and IL Is estimated by astroh-
omers that it gives us four times as much
light as any other star visible In our lati-
tude.
The reasons generally given by scien.
lists for the phenomena OF hearing sound
| fartherest just before storm is thht the
air, being moist, has more than its normal
conducting power, and that the low lying
strata Of clouds confne the sounds TO the
earth.
An artesian well was completed at Da-
venport, Iowa, last week, at a depth OF 900
feet. The pressure 1t is said carries the
water twenty-five feet above the surface Of
the earth. The stream Is six inches in di-
ameter and flows at the rate Of 400 gallons
per minute.
The preliminary steps have already been
taken for the holding Of q worlds fair, In
New York city, in 1888. At arecent meet
ing Of prominent citizens and captiists Of
that great metropolis, resolution was
adopted asking Congress to take measures
to give the proposed affair "offioial sane
tion and aid commensurate TO its import
ance."
The manufacture OF Glucose is becoming
one OF the most extensive industries in this
country. Corn sugar Is now used for all
the various purposes for which any is used,
except for first class confectionery, and Is
not only used largely IN this country, but
great shipments are constantly being made
to Europe, where It isin great demand
Scientists have adopted the theory that
the duration Of animal life should be Ave
times the growth Of the animal or being
Thus, man gets his growth In twenty years
and should live to be hundred years old
The camel is eight years in growing and
lives forty years. The horse reaches. ma.
turity in Ave years, and seldom lives be-
yond twenty-hvei and so II is with otheI
animals.
Speaking on the subject Of insanity, at q
recent meeting OF the Medico-Legal society
Of New York Dr. George NJ. Beard TO-
marked that Insanity is barometer Of
civilization, and as we advance higher II
the arts and sciences, so will insanity be
come more prevalent among as. Intense
application, brain work and Indoor life arr
, the ageneieswhioh most frequently bring Il
about, Among savages or barbariani
, there is but little or none OF Il. The intel
iectual activity OF the women OF to day il
mother is so will the child be in an inten
, ser degree. An im
proved system Of education, with les
cramming, would tend 10 reduce the in
! crease Of insanity. There is much in thi
: idea that should at least interest teachers
, and parents OF the present day in the bring
/. ing up OF the rising generation.
