CLoUEr and Ritter, working separate
", have each discovered that all COM
mercial grape sugar contains arsenic in
small quantities.
THE St. Gothard Tunnel makes steady
progress, no less than :, 1000 workmen be-
ing engaged upon it. Nearly 10 tons
of dynamite are used per month.

By the end of the present year, of 81
chief towns of departments in France,
only 26 will not be provided with direct
Geographic communication with Paris.
A New steam-hammer in the estab-
ment of Messrs. Park Bros. & Co.,
Pittsburg, weighing Is tons, and costing
1000, will, it is said, be the largest in
the country.
TANNING, says M. E. Ador, can be
fastened by applying phosphoric acid,
as it enables the tannin to penetrate the
skins more rapidly through its hinder
ing the tanning of the albuminoid SUBJ
stances.
THE production of Bessemer steel
rails in this country since 1867, when
they were first made, has increased to a
marvellous extent. In 1867 it amounted
to only 2,555 tons; in 1872, to $4,000
tons, and last year to $40, 200 tons.
ED1soN's luminous horseshoe will
probably be first put into practical use
on shipboard. The new steamship, now
being constructed in Chester, Pa, for
the Oregon Navigation Company, is to
be fitted out with three-candle electric
light in each stateroom.
In Brazil telephone communication
has been established among many of
the large plantations, different private
parties, and Government offices. At
Rio de Janeiro telephones are used for
sending messages between the Senate
and the Lower House.
DE LEssEPs has eight working par
ties, comprising over $50 men, survey
ing the Isthmus for the nter-oceanic
canal. As the parties are contiguous to
railway and telegraph lines, their pro-
visioning and supply, as well as their
general direction from Panama or As
pinwall, are easily managed.
FROM some recent experiments it is
considered desirable to make telegraph
wire of an alloy of aluminium and iron.
While the wire can be made much
smaller than the present gauge, it will
be stronger, of less susceptibility to
atmospheric changes, and of greater
conductivity than the ordinary wire.
SOME months ago Herr Phillip
placed in the hands of the Chemical
Agricultural Commission of Zurich a
bottle containing sample of his pre-
served milk. 1t had been eight days in
an ordinary living room, often at IS
deg, without perceptible effect on quail
ity, taste, or appearance; it creamed
like any other milk, and butter might
have been made from it. The same
results were obtained at various other
times, and the most careful tests of the
President and analyst of the Commits
sion failed to detect in the milk any
doubtful ingredient, such as some ex-
perimenters have used for milk preser-
walton.
The Weather Bureau has invented an
instrument which will show the proba-
bilities as well as they are given by the
Bureau. The Instrument has dials
which on certain indications of wind
and atmosphere will predict certain
kinds of weather, the prediction being
based on a thousand observations. In
other words a thousand observations
heretofore made showed that certain
conditions of the wind and atmosphere
brought about within day or two or
three days certain weather. 1t is in
tended to have one of these instruments
placed in post-offices of all the cities, so
that every one can be his own "Old
Probabilities.
THE railway for the ascent of Vesuvi-
us is now finished. 1t is 900 meters in
length, and will enable tourists to as

line has been constructed with great
care upon sound pavement, and it is
