SCIENTIFIC MISCELLANY.
The rapidity Of the circulation is such
that, lift flowed in a straight line at the
same rate, it would run one hundred and
dfty fcct per minute.
Experiments by P. Hoglan show that
calo,nel may DO decomposed in the hu-
man system, with the formation of the
dangerous poison corrosive sublimate.
A piece Of pine has been lately shown
by Gopport which has been converted to
. half-carbonized state aud reduced to
qne.f earth its original bulk by the simple
seton Of pressure, exerted during Pc
Rod of two years.
Experiments of NJ Pasteur in vaccina-
ton for splenic fever have proved entire
" successful. The new vaccine matter
can be cultivated ut pleasure, transported
without injnry, and preserves the ami
mails into which it is introduced from q
mortal disease.
Ninety-two people have been enrolled
in the Sunday Science School of Edin-
burg, Scotland, and from November to
judy Inst the institution had an average
attendance Of sixty young people whose
late business hours prevented their at
tending the evening classes.
NJ. Fleischen has made o comparison
between the bark Of young oaks grown
respectively upon sandy loans, upon
peaty soils that had been once burned,
and upon a similar soil that had been
thrice burned, and found the proportion
Of tannin highest in the product Of peaty
soils.
According to French entomolgist, the
wool of different countries may be distin-
guished in market by the varieties OF
beetles which inhabit the bales. He has
identified AZ pieces in Austrian wool; 50
in South African wool 80 in South Amer
lean wool; 16 in Spanish. wool, and 6
in Russian wool.
Az upwards Of five hundred tons of
sugar made from starch are daily placed
on the market, Prof. Wiley suggests the
desirability Of giving the substance a
distinctive name. He proposes the name
of amylOse from the Latin -1mylum starch.
"Amylose" will include all sugars and
syrups made from starch.
Cyclones arc observed to extend over
2 circle from 100 to 500 or, sometimes,
1000 miles in diameter. In the West
Indies they are sometimes as small as
100 miles in diameter, but lilate to 600
to 1000 miles on reaching the Atlantic.
They sometimes, however, contract, il,~
crsasing greatly In violence during the
process.
A naturalist ~asscrt that cranes
carry small migratory birls-unable to
Perform the flight Of three hundred and
fifty miles across tho Mediterranean
Sea ON their backs. In flocks of cranes
travelling southwark across this sea,
little birds Of many species are observed,
frequently flying from their perches only
TO return q moment after.
Some remarkable and suggestive pecu-
jiarities are found In human jawbone
from tho Schipka Cave of Aloravia.
Stone Implements found with the bone
indicate that it belongs to the stone age.
In development the jaw is that of
child, but i is Of great size. Its shape
indicates the absence Of any chin and
has other peculiarities found in greater
degree in the higher apes.
The precision Of modern engineering is
forcibly illustrated by the recently &C
feat of picking up long I'M
used ocean cable from depth Of two
thousand fathoms. Tho scientific engi-
neering which locates fault with SO
much exactness aud SO readily finds a
moro thread two miles under the sea must
odd much to The 3curity and value of
ocean telegraph property.
A remarkable natural phenomenon
at Hungary on the 9th Of June.
Tho Bnznau Mountain, near the village
Of Paptelke, suddenly broke in two; a
great assure 100 to 1875 feet wide, so to
100 feet deep and 1900 to 1900 feet in
length being formed by the rupture. A
landslip took place at the same time,
md field was moved bodily some thirty
fest nearer to the village.
Some interesting observations con-
corning the comparative longevity of
men and women in Europe have been
made by the director Of the Vienna
Statistical Bureau. Out of 1O2, 1891 in
dividnals who have passed the age Of
ninety years, only az, 528 are men, and
C, 303 are women. He also finds that
there are but 141 male oentenarians to
24l women who have reached q hundred
years Of age.
1t is we'll known that the feeblest cleo
trio currents produce audible sounds in
the telephone, which is more sensitive to
weak currents than the most delicate
galvanOmetr. NJ. Pellat lately declared
that the heat necessary to warm kilo-
gramme 1.-TWO and quarter ponnds> of
water one degree, if converted properly
Into the energy of electric currents,
would suffice to produce in telephone
