As owltzer land to lose Its glacjers1
The subject bears close resemblance

British coal beds. II will scarcely be-
come acute In our time but nonethe-
less scientific observations of the move
ment Of the glaciers during 1905 shows,
as similar observations in previous
years have shown, a shrnkage in the
surface. Some Of the glaciers have
shrunk as much as 300 yards since
1900. In no instance has growth been
reported.
The city Of Vienna has undertaken
the installation Of what is perhaps the
most remarkable electric, or electrical.
ly lighted, fountain in existence. 1t is
situated in the Schwartzenbergplatz
Underneath the fountain, in huge
cemented chamber, are placed twenty
seven rejecting lamps, capable Of pro-
ducing seventy different luminous and
colored effects The light is transmit
ted through the waters of the fountain.
The light power Of the plant is esti-
mated as equal to 900,000,O0O candles.
According to the results Of recent ex-
periments the fame Of acetylene is per-
haps the hottest known except that of
the electric arc. The following figures
have been given by Mr.. Maffi: Bunsen
burner, 1871 degrees; acetylene flame,
2,548 degrees; alcohol fame, 1,7O5 de-
grees; Denayrouze burner-haif dlco-
hol, half petroleum-2,053d degrees; by
drogen flame, in air, 800 degrees; gas
| jet flame, with oxygen, 1900 degrees !;
oxygen flame, 2,420 degrees. These are
all Centigrade degrees. One degree
Centigrade equals one degree and eight
tenths Fahrenheit.
The lowest temperature yet recorded
says medical Journal, Is that reached
recently by X. Olszewski in an attempt
to liquify helium. BY the aid of solid
hydrogen he cooled the gas to minus
1853 degrees S. Under $50 atmospheres'
pressure; then, suddenly releasing the
pressure to that of the atmosphere, a
degree Of cold was created which, by
calculation from Laplace and BLOSSOMS
grees G. Helium, however did not
liquify, and he accordingly assumes
that its boiling point must be below
minus 271, and that there is but little
prospect of reducing it to liquid.
A French scientific writer points out
that mere gain in weight should not
!, In itself be taken as an indication of
improved bodily condition. 1t is, ac-
cording to him, rather question of the
density than the quantity Of tissue
which covers the bones. When in
creased weight results from increased
density, then the health is really i'm
proved. In order that this principle
may be practically applied, he suggests
the use Of baths containing a known
quantity Of water and supplied with
appliances for measurement whereby
the density Of the immersed body may
be calculated, in the manner in which
Archimedes ascertained the density OF
