j. BALLANTYNE HANNAY has written
to firm of diamond dealers saying his
discovery will not affect their business,
as the cost of producing very small
quantities of his combination is so great
as to relegate the process to q mere
laboratory experiment.
DANBoURG, French engineer, says
that he has devised means for trans
porting large vessels over the isthmus,
however steep, and an experiment is
shortly to be made at Argenteuil by lift
ing ship of 1900 tons from the river
Seine and taking it on rails to another
point on the river.
AS evidence of the enlightened condi-
ton of the Japanese as compared with
their neighbors in China, it is interest
ing to learn that the duplex system of
telegraphy with the Morse instrument
has been in successful working for some
months past on one of the longest of
the Government ines-that between
Yokohama, Kobe, and Nagasaki.
THE French Chambers, at the insti.
CATION of NJ. de Freycinet, have voted a
sum of 100000 francs for the sending of
exploring missions into the remoter
parts of Algiers and Senegal. Their
immediate object is to trace the lines of
future railways, but the indirect infiu-
ence on the extension of our geographic
cal knowledge is most important.
THE immense coal-fields of the Chi
nese Empire are slowly being developed,
the superstitions of this strange people
being overcome. In district near
Tchang, on the Upper Yang-tsi-Kiang,
coal-field extending over seventy five
square miles has been tapped. At Wo-
tze-kow ten beds of coal have been dis
covered; one of them, lying only 100
feet below the surface, is being worked,
and at least 1 200, 900 tons of anthracite
have been exposed.
A NEW Photographic process has boon
discovered in Japan. One of the SUBJ
stances employed in the manufacture of
Japanese lacquer has the property of
becoming almost as hard as stone under
the action of light. A slab covered with
this material, and duly exposed behind
a Photographic negative for twelve
hours, is scraped, when the softer parts
are rubbed away, and the hardened por-
tons stand out in a low relief. The slab
can then be used as block for print
ing.
DURING the year 1879 five comets
were seen by astronomers, two of which
were periodical, and their appearance
predicted. Of the other three, one was
discovered by Swift of Rochester, while
the available and necessary elements to
two were computed by the Boston Sci
entifc Society, from their own observa-
tons. Two periodical comets are ex-
pected during the latter half of 1880.

OYsTER-cULTURE is extending in Ger
many, and society has just been estab-
lished at Hamburg for the purpose of
planting new oyster beds in Schleswig-
Holstein. The east coast from the from
tier toward Angeln has been selected as
most suitable for the growth of this
favorite edible, and the necessary pre-

100000 of young one and two year old
oysters will be deposited for the purpose
of stocking the beds at the marked-off
stations. The small American oysters,
which appear to be acclimatized already
upon the clay banks of the Little Belt,
have been selected for the first attempt
at oyster culture on the coasts of Schles-
wig Holstein. The Prussi.n Govern
ment mot only gives its consent to the
undertaking, but is also ready to protect
it by establishing guard along the new
