ITALY.

An Imperil decree ordering the abandonment of
all prosecutions for high treason, was proclaimed
at Mantua amidst the warmest acclamations.
The Austrian commandant of the town and
fortress of Ancona has issued an order forbidding
more than five persons being together in the streets
after sunset, and directing that the arrival of tra-
vellers must be notified to the police an hour after
at the latest.

The Parlamento of Turin states from Florence,
14th instant, that, in the case of Guerrazzi and
others for high treason, the Attorney-General has
proposed—imprisonment for life for Guerrazzi, ex-
provisional chief of the Executive ; 63 months' im-
prisonment for Romanelli, ex-Minister of Grace and
Justice under the provisional Government ; 90
months' imprisonment for Capecchi, an old officer,
convicted of having spoken publicly against the
Grand Duke ; 11 years and 3 months' imprison-
ment for Montazio, convicted of high treason com-
mitted by means of the press ; and 56 months'
imprisonment in a house of correction for Dami,
ox-President of the Popular Club of Florence, and
Pantanelli, Secretary of the Popular Club of Siena.
The Deputy Attorney-General, in summing up the
case for the prosecution in that portion which had
been carried on at Pistoria, but had subsequently
been annexed to the prosecution at Florence, pro-
posed—imprisonment for life for Major Petracchi,
56 months' imprisonment in a house of correction
for Cimballi, with five years' surveillance of the
police after the expiration of his punishment.
Piccini, Agostini, and Lottini are to be set at
liberty.
The Vienna papers mention that the search or-
dered by the Piedmontese authorities in the forests
on the Lombard frontier, led to the discovery of
3,000 guns and a large quantity of ammunition,
secreted by the refugees in case of the success of
the attempt at Milan.

SPAIN.
We have received the Madrid journals of the
16th, but their contents are without interest. The
Chamber of Deputies continued to be occupied with
the verification of the electoral returns, and the
Senate was not to sit until the 18th. The weather,
which for a few days had relaxed in severity, had
again become very cold, and the influenza was very
prevalent.

ASSOCIATED SOCIETIES OF EDINBURGH -UNIVERSITY.—
On Friday evening, at a meeting of these societies, Sir
Edward Bulwer Lytton was, without a contest, elected
their first honorary president. The hon. baronet is ex-
pected to visit Edinburgh and address the societies in
December next.

A SCIENTIFIC GOLD-DIGGER.--AMong the passengers
by the Falcon, which arrived in the Mersey on Tuesday
from Sydney, was Mr. John Calvert, a geologist, who
has been 11 years in the Australian colonies. During
that time he has made a geological survey of all the mi-
neral districts in Adelaide, Van Dienien's Land, Sydney,
and New Zealand, and he has brought back with him a
map of the western goldfields which alone is 30 feet long.
He has also a large number of drawings, some of them
valuable in a scientific po'nt of view, and others pleas-
ing and instructive, as giving a sketch of life and man-
ners at the gold diggings. Mr. Calvert has himself been
engaged for eight years in tracing the auriferous veins
and in procuring gold. A short time ago he sent home
a block of quartz weighing a ton and a-half, and he has
brought with him in the Falcon 730 nuggets of the pre-
cious•thetal. One of the pieces weighs 231 b. of pure
gold, and we had the opportunity of seeing a piece weigh-
ing 1 Ylb., which is considered one of the best specimens,
being, in the state in which it was discovered, above the
standard. The amount of gold brought home by Mr. Cal-
vert is about 3301 b. gross, between 701 b. and 801 b. being
dross or quartz more or less mixed with the gold. The largest
quantity he everobtained in one day was 761 b. weight, which
he broke off with his geological hammer in pieces va-
rying from half-an-ounce to 21b. weight. He' had been
led to the spot by auriferous indications, increasing as he
came nearer, for a distance of nearly- 40 miles. The
quartz vein ran north and south, and was from about 9
to 15 feet in breadth, half-a-mile from where he robbed
it of its precious treasure. It stands out in large blocks
of from 15 to 20 feet in height, looking in the distance
like white houses. This place is distant from Sydney
about 215 miles, and a long way from any at present
worked goldfield. During the latter part of his resi-
dence in Australia, Mr. Calvert had a camp, and three
men as assistants, and, properly equipped, he pursued
his scientific survey. Among his discoveries, he found
diamonds, rubies, and many valuable minerals, in which
the Australian colonies abound. We understand that
Mr. Calvert will proceed direct to London, where he in-
tends to get his drawings and maps transferred to can-
vass, for the purposes of exhibiting them as a panorama
of the gold-fields, illustrative of lectures which he in-
tends to deliver on the origin of gold, and on the'colo-
nies towards which so many thousands of his fellow-
countrymen are now turning their attention.—Liverpool
