Platinum can now bo drawn into
wire strands so fine that twenty-scven

"A cerate for wounds, cuts sores
burns, scalds and the like: Resin, 4
pound; clarified beef suet, ounces; boil
a quarter of an hour; add two ounces
beeswax; boil for an hour longer and
allow to set.
The Milky Way holds probably al
least 20, 191, 900 stars, and as each is q
sun, we presume it is encircled by al
least so planets. Counting up these
figures, we arrive at the magnitude of
1000, 055, 600 stars. A thousand million
of stars! Who can comprehend it? Still
this is only a part Of the universe. THE
modern telescopes have discovered more
and similar milky ways still farther
away.
"A curious fact has recently been
noted by the fine steel workers at Shelf
field, England. Ii is this: Fine edged
tools assume blue color and lose all
temper if exposed for any considerable
length of time to the light of the sun,
either in summer or winter. A similar
effect is exercised by moonlight, large
cross-cut saw with which the expert
menters We're working having been
put out of.shape and it's temper ruined
by single nights exposure to first
quarter moon"
-Coun tries in Europe with a wheat
crop above the average this year are:
Austria and Wallachia, 10 per cent;
Hungary, . per cent; Prussia, 4 per
cent. SaXony, Ia per cent; Denmark
and Belgium, 3 per cent; Switzerland,
s per cent, and Servia, per cent. The
harvests below the average were those
of Italy, 20 per cent; France, 6 per
cent; Great Britain and Ireland, 9 per
cent, and Egypt, 20 per cent.
On clear night an ordinary human
eye can discover about 1000 stars in
the northern hemisphere, most of which
send their light from distances which
we cannot measure. How large they
must be! Round these ], 900 stars circle
$4,000 other stars of various sizes. Be
side single stars we know of systems of
stars moving round one another. Still
we are but u short way into space as
yeti Outside our limits of vision and
imagination there are, no doubt, still
larger spaces.
-Boro-boraX is new preparation,
discovered by Jaeniclle, which is formed
by mixing equal parts of boraX and
boric acid in boiling water. When the
water cools the greater part of the sub
stance crystallizes out Its antiseptic
and therapeutic properties resemble
those of boric acid, but it has a neutral
reaction and is much more soluble. At
ordinary temperature, 1G parts of boro-
boraX dissolve in 100 of water; at 100
degrees f., so parts dissolve in 100 of
water; while boiling water dissolves 70

The coolest known spot on the
earth's surface is on the Eastern slope,
q shelving mountain that runs down to
near the waters edge, on the eastern
bank of the Lena river, in northeast
Siberia. The spot in question is nine
and fourth miles from Serkerchoof,
about g. north, and longitude 1874 east.
DIR. Woikoff, director of the Russian
Meteorological service, gives the mini
mum temperature of the place as being
SS degrees below zero. 1t is a place of
almost perpetual calm. In the noun
tains near by, where windy weather is
the rule, it is not nearly 80 cold.-St.
Louis Republican,
AT the recent international con
gress of physiology at Liege,, Prof. Her
mann demonstrated his method OF
photographing the sound of vowcls.
The vowcls We're sung out before one
of Edisons monographs. Immediately
afterwards they were reproduced very
slowly, and the vibrations recorded by
a microphonc. The latter was fur
nished with u mirror, which reflected
the light of an electric lamp upon a
registering cylinder, covered with
sensitized paper and protected by an
other cylinder with small opening
which gave passage to the rays OF light
from the reflector. by this means was
obtained very distinct Photographic
traces, and the constancy was remark
able for the different letters. Scientific
