The Bartholdi statue of New York ls
to be lighted at night by shaft Light
from torch which will 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 base 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 sdee1
lded in the soil foes'ssl lt5g
saws it IS the largest aerotlte on recoror
and weighs fully 200 tons. Its compost
tion. is chromium, nickel, aluminium, /
copper, magnesium, and tin.
Professor Stamford, the English Edf
son, has discovered q new: substancs

In certain combinations it is as nutritioI
as grape sugar, while in one OF its ion

arabic not less than twenty-six times.
"The great Lick telescope" says
Boston Herald, "whcn mounted

ffty-five feet length-nearly fifteen feel
longer than the largest one ever maae. :

ever known of the latter style was Dr;

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
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 ls
produced by distant storm. Thunder
seldom accompanies heat lightning, the
sound reaching only about twelve miles,
while lightning is often seen, by renee.
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
n wire q mile in length, trailed behind a.
ship will so charge the water with eiec'
tricity that vessel coming within half a
mile of another thus equipped may com
municate with it. "The principle" nc
saws "is not new; it is old, with new
use waiting for commerce to utilize it. :!

The results of experiments made thu.
far in the publication of water by acra5
tion have attracted much notice. This
method is we'll known to be based on
the discovery that the action OF m
purifying water is greatly Increased by
mixing the air and water under pressurel
A Fairmount, Philadelphia, turbine e9
pine, was converted into an air-pum
which delivered twenty per cent,
volume. of free air into the water =
this being the proportion found
sary to surcharge the water. An
showed that the quantity offree oxy
the aerated water was seventeen per
greater than before aeration, while
quantity of carbonic acid was fifty
per cent. greater, and that OF the
dissolved gases was sixteen per,
| greater
