An invention which must prove o
much Importance in architecture an'
sculpture has recently been made by DR.
Gehring Of Lanishut, Bavaria. By means
of an cnamcling liquid, he claims to be
able to render an, kind Of stone or &C.

the appearance of any other mineral de

to metal, and is said to cffectually pre-

"A London journal reports that a lew
and somewhat remarkable invention has
appeared ut Turin. 1t consists in the
application of light giving materials to
printing ink, by which print becomes
luminous in the dark, so that in future
il will be possible to read at night, in
bed or during a journey, without the as
sistance of candle or lamp. 1t is said
that Il new daily paper is about to be
printed il Turin with this luminous ink.
M. Blerzy describes an interesting
experiment in physics which is readily
performed by any person. Place an iron
pot full Of water on the fire. When the
water is boiling vigorously remove the
pot; then, if the hand be brought into
contact with it, only moderate heat is
felt. But hmm, diatrly the water ceases
to boil, the sensation of burning is re-
ceived. The only risk attending the ex-
pertinent, states NJ. Blcrzy, is that of
blackening ones hand.
Sig. G. Bignami Sormani Of Milan
has found that the density of snow at
time Of falling varies remarkably. Dur
ing his observations he has found snow
so dense that it weighed over thirty
pounds TO the cubic foot, being nearly
half as heavy us water; While the light
est snow weighed by linn showed but a
1riile more than two and half pounds
per cubic foot. 1t is assumed that the
density of new fallen SHOW is ordinarily
about one eighth that Of water, or, in
round numbers, eight pounds each cubic
foot.
Meteor ologists have found that Uni
ted States storms usually advance from
the Upper Mississippi Valley toward New
York and New England, less frequently
toward Virginia, and seldom toward the
Carol!nas. American storm centres most
frequently pass off the coast between
forty-iive and fifty degrees North lati-
tndc. The great waves Of high baron,-
cter, with fierce northwest winds in their
front, usually advance from ii g Rocky
Mountains toward Virginia and the Car
olinas, hut less frequently toward New
England.
