A FRIGHTFUL HINT !—The Einita ltaliana of the
14th calls the attention of Garibaldi to the follow-
ing points ;—That Caprers is a rock where there
are not many houses, and where he resides with a
very few persons and without any precaution. 2.
That the Greek Archipelago is full of small islets
full of pirates, always ready for plunder. 3. That
consequently it might happen that, seduced by
the promise of a rich reward, some pirates might
surprise and carry him off, or perhaps kill or throw
him into the sea. "For those reasons," adds that
journal, " we recommend him to keep a sharp look
out."

ANOTHER FAMINE IN HUNGARY.—The Pesth
Htirnok professes to have learned from reliable sources that
the recent hard frosts have destroyed nine• tenths of tho
rape and four-tenths of the wheat sown in Hungary. The
loss sustained is estimated at 40,000,000f1., but the accuracy
of the estimate is questionable.

THE MURDER ON BOARD THE SAX.ON.--There
is a naval court-martial in session at the Philadelphia Navy
Yard, for the trial of Acting Master Charles Danenhower,
of the United States navy, upon a charge of murder on the
high seas, in shooting James Gray, mate of the British
barque Saxon, in October last, off the coast of Africa. The
charges are preferred by Mr. Seward, Secretary of State,
upon the information of Lord Lyons, the British Minister.
The case was submitted to a court of inquiry, after the
return of the Vanderbilt, on which the accused was serving,
and he was fully exonerated from blame, and justified for
the act, and the finding, it was understood, was approved
by the Secretary of the Navy. His lordship the British
Minister, not being satisfied with the result of the pro-
ceedings, has induced the Government to convene a court-
martial for the trial of Mr. Danenhower, and the case is,
as we have said, in process of trial.—.2lrew York Berea.
PHOTOGRAPHY.—Last week M. Poitevin own.
niunicated to the French Photographic Society a
curious process of his for obarining photographs in relief
on porcelain, a process which he calls helioplastie engrav-
ing. If a thick layer of bichrumatised gelatine receives the
impression of light through a negative, and then put into
water, those parts only will swell up that have been pro-
tected from the solar rays, so that all the shades of the
print comes out in relief, while those answering to the light
remain depressed. In this state

plate is covered with collodion containing no bromide, but
known to yield good impressions oy the ordinary methods.
It is exposed to the action of the silver bath, then washed
with filtered rain water, and afterwards with a mixture
of half a gramme of camphor, 100 cubic centimetres
of absolute alcohol, and two of acetic ether, so that
none of the water of the previous washing may
adhere to the plate. For this purpose the liquid is
sip A-ly delivered to the, plate by one of the corners, and
allowed to run di at the opposite one, driving the water
before it. The plate is now left to dry, proteoted from dust
and all impurity. In order to develop° the print he uses
a solution of -- 1 gramme of pyrogenic acid, 2 do. of citric
acid, dissolved in 100 cubic centimetres of distilled water,
and a few drops of a solution of nitrate of silver at 6 per
cent. The plates thus prepared may be preserved a month
without losing their sensibility, and may be developed
several weeks after exposure to the light.
Advices from Tours state that the Bishop of
Evreux has got much worse, and is now daagerously ill.
The Archbishop of Tours, at whose house he has been stop-
ping, administered the last sacraments to him the night
before last, and prayers have been offered up in all the
churches.

The King of Greece has invited the represehm
tatives of France, England, and Russia to accompany him
in his excursion to the lonian Isles.
