The Bartholdi statue of New York is
u be lighted at night by shaft-light
from torch which W Ii be seen ninety
miles out to sea, and therefore long be-
fore any Lighthouse on the coast, and also
by four large lights at the ba.e of the
statue.
After months of search Professor
Jonathan limerick, of William and Mary
College, has discovered the aerolite which
fell in Washington County, Penn, Sep
tember 14th, 1885. 1t was found deeply
imbedded in the soil, Professor limerick
says it is the largest aeTo,!te on record,
and weighs fully 200 tons. Its compost
tion is chromium, nickel, aluminium,
copper, magnesium, and tin.
Professor Stamford, the English Edi-
son, has discovered a new substance
which promises TO become popular att
ele of commerce. "Algine,'' residuum
of macerated fucus (sea-tang) combines
the qualities Of mordant, an esculent.
and a superlative adhesive. 1t fixes a
variety of colors used by cotton-dyers.
In certain combinations it is as nutritious
as grape-sugar, while in one of its forms
its adhesiveness exceeds that Of guw
arabic not less than twenty-six times.
'The great Lick tel scope" says the
Boston Herald, "when mounted and
swung against the sky, will have focus Of
tifty-fve feet length-nearly fifteen feet
longer than the largest one ever made.
1t will be a refractor, which means that
the image is formed directly to the eye
by the object glass, as contradistin-
guished from the Gregorian and Her
schelian telescopes. The largest instrument
ever known of the latter style was DIR.
Herschel's. The tube lacked but eigh
inches of being forty feet in length"
Meteorologists have found that there
can be no thunder and Lightning without
rain. When thunder is heard beneath u
clear sky, the reports must either come
from distant clouds or be the result Of
some other cause than discharge OF
electricity. Harvest or heat lightning is
produced by a distant storm. Thunder
seldom accompanies heat lightning, the
sound reaching only about twelve miles,
while lightning is often seen, by refec-
tion upon nearer clouds, at a much
greater distance.
Professor Bell is confident that tele-
, phonic communication may be established
( between passing vessels at sea. He believes
. wire mile in length, trailed behind q
, ship, will so charge the water with cleo
! triclty that vessel coming within half a
mile of another thus equipped may com
. municate with it. The principle" he
g says, ''is not new; it is old, with new
use waiting for commerce to utilize it.

O of the results"
r The results of experiments made thus
: far in the publication of water by aera'
! ton have attracted much notice. This
g method is we'll known to be based or
v the discovery that the action Of air IL
n purifying water is greatly increased by
d mixing the air and water under pressure
n A Fairmount, Philadelphia, turbine en-
b gine was converted into an air-pump
e which delivered twenty per cent, b.
= volume, of free air into the water main
Vt this being the proportion found neces
81 sary to surcharge the water. Analysl
showed that the quantity ffree oxygen IL
the aerated water was seventeen per cent
greater than before aeration, while tn
quantity of carbonic acid was iGty-thre
!, per cent. greater, and that of the tota
W dissolved gases was sixteen per cent
- greater
