A letter (torn Rome, of the 20th, in the Nazionale
of Florence, states that the Pope has again postpimed
his return.

The Concordia of Turin states, that on the 22d, the
Genoa and Milan diligence on being examined at the
Austrian frontier, was found to contain a parcel of
portraits of Mazzini, Garibaldi, and other revolu-
tionary characters. As none of the travellers thought
it safe to claim the parcel, they were all taken before
a commissary of police, who sent them under escort
to Milan, where, after undergoing a minute search,
they were set at liberty.
Letters from Naples, of the 16th, announce the
arrival at Messina of the French squadron that was
stationed in the Archipelago. It was expected at
Naples with the first favourable weather.
The Nazionale, of Florence, of the 22d inst., con-
tains the following :
" The Tuscan Government would neither be constitu-
tional nor free if it was true that it refused the mediation
of Piedmont for the settlement of its difference with
England, and insisted on the mediation of Rus-
sia. By declining that of Piedmont it would
betray disinclination to pursue a constitutional
course, and, if it demands the mediation of
Russia, it is evident that the measure has been im-
posed upon it, and that. consequently, it is not free. It
is not. the interest of /tidy that the influence of Russia
should increase in the peninsula, particularly in Tus-
cany; and, moreover, they offer a gratuitous insult to Eng-
land by proposing to her a mediation which she cannot
and will not accept. Why,expose Leghorn to be block-
aded by the English squadron? If the Tuscan Govern-
ment accepts the Sardinian mediation, reliance may be
had in the sincerity of its promises, and it will prove that it
acts freely; but if it claims the Russian mediation, it
places itself under the necessity of continuing to violate
the constitution."

ANOTHER BLOIT-11P AT HOONSLOW.—Lient.-Colonel

the Earl of Cardigan bas placed Major Joner,of his
Regiment, under arrest. We shall learn in a day or two
the particulars of this fresh exercise of authority. What
a chapter might bo written on the arrests in this regi-
ment since it fell into the hands of its present com-
mander!

Amongst the en dits of the day, in reference to the
office of Adjutant-General, it is said that Lord Fitzroy
Somerset is to succeed to the office, and Lord Charles
Wellesley to become the Military Secretary to the Com-
mander-in-Chief. We have strong reasons for dis-
believing these remota&
DEATH OF LIEUTENANT-GENERAL SIR JOHN MAC-
DONALD, G.C.B.—The Adjutant General to the Forces,
whose death took place at his residence in Bruton-street
on Thursday. was an officer of fifty-five years' service,
a considerable portion of which was passed in the Field,
and thirty .two years of it in the bureau of the Horse
Guards. He entered the Army in 1795, served
in Ireland during the rebellion, was afterwards at
the capture of Malta, the landing in Egypt,
and the battle of March 1801. In 1807 he was on
the Staff of Lord Cathcart, in Swedish Pomerania, and
subsequently served at Copenhagen. He was afterwards
at Walcheren, and in the ensuing year was Deputy-Ad-
jutant General at the defence of Cadiz, and the battle of
Barossa. During the Peninsular War, he was present
at the actions on.thefNi.ve and the sortie from Bayonne.
Sir John Macdonald was appointed Deputy-Adjutant
General In 1818. On the death of the lamented Sir

Henry Torrens, Sir Herbert Taylor succeeded to the su-
perior office of Adjutant-General, and Sir J. Macdonald
had a regiment given to kin) by way of compensation for his
disappointment. On the death of Sir Herbert Taylor he
became Adjutant-General. His professional capability
was remarkable. He had, in the earlier period of his
career, great sagacity and application. His official com-
positions were distinguished alike by good taste and per-
spicuity; and he entertained a strong sense of justice,
though ate did not always evince the strongest judgment.
By his death the Colitnelcy of the 42d Highlanders be-
comes vacant. He obtained the Regiment „upon the de-
mise of Sir George Murray.

MINING INTELLIGENCE.
(From the Mining Journal of this day.)
An &lenge amount of business hes been transacted
this week, and shares generally continue firm in most
of our leading mines. The reports received from tLe
mining districts during the week aro of a satisfactory
character.

Tincruft continues in the same improving position as
last reported, and a great many shares have changed
hands at an advance.

Alfred Consols have very much improved since our
last, and transactions have taken place at a considerable
advance, and shares still in demand. Tbe'7o fm. level,
east of shaft, is worth 20L per fm.—still im-
proving. The wince under the 60 east is worth from 401.
to 50/. per fathom for copper alone; the 60 end is iearly
solid ore, worth 70/. per Iw.
A large number of Penzance Consols shares have
changed hands during the week, and the mine is repre-
sented to be progressively improving.
Levant, Boswidden, and Botalluck shares had ad-
vanced. At Bosorn Mine, a fine lode of tin has been
discovered going down in whole ground under the
level. A new water-wheel is in course of erection,
which, when completed, tin will be returned at once.

At Spearne Consols, a rich lode of tin has been cut in
the 60 fathom level on Button White's lode; this being
in virgin ground, will give 66 fins. of unexplored ground
from the 60 to the 128 fm. level.

Several trrnsactions have taken place in the shares of
the Wicklow Copper and Sulphur Mining Company.
This company was formed at the close of the last year
for working copper ore, lead, and sulphur in the rich
mineral basin situate near the Vale of Avoca, which
embraces the well-known mines of Bellymutagh,
Bally-
gaban, Cronebane, and Connoree, all of which have
uniformly returned large profits. Sales of lead ha►e been
effected at good prices, and preparations are making for
the shipment of sulphur ore, for which there is a de-
mand at remunerating prices, for the alkali works in and
near Liverpool.
At Wheal Providence (South "Sydenham), a fine court•
of lead was recently discovered, and a further discovery
has been made during the week, more to the west of the
former course.

At the Treviskey and Barrier bi-monthly account, a
dividend of 101. per share was, declared on the former.
The profits on "the two' 'Months' working amount to
1,2551. Is. 5d., which, added to credit from last account,
leaves in hand, after payment of the dividend, 921.45. Id.,
with ore bills not yet et maturity. The lode in the 236
end is producing 2 tons of ore per fm., and two stopes
in the bottom of the same level, are turning out 5 tons
each per fm. In the 248 fm. level the lode is yielding 7
tons of good ore per fm.; 505 tens have been samplsti
for,January and February, and 450 tons are ezpectsd to
be raised for March and April.

At the Lamherooe Wheal Maria meeting, the state 11
-
meat of accounts showed a balance of 2371.95. 2d. against
mine. From the great improvement which has recently
taken place (and, acting upon the recommendation of
Mr. A. Murray, jun., the adoption of more vigorous
operations), the meeting resolved upon a special meeting
being convened for the II th April, to arrange fur a suf-
ticieut call to meet their improved prospects.
At the hi-monthly meeting of the Hencock Silver-
Lead Mining Company, the balance-,heel showed a
credit of 1311. in favour of mine; but fur the purpose of
meeting costs of future operations, a r all of 3s. per share
was deeMed necessary. The prospects of the mine are
considered highly favourable.
The Welsh mines, especially in Cardigan, are repro--
tented to be looking remarkably well. At Esgsir LI. e,
the taunter lode, in the 52 fir. level, has improved,
yielding from 20 to 25 cwts. i f ore per fm. At Llwyn-
melees, the 8 fro. level west is in a very good course if
ore, and the Mopes over this level have the finest lode
yet seen-30 tons have been sampled.
A large number of shares in Black Craig and Craigton
have changed hands.
In Foreign Mines there has been a considerable amount
of business transacted in Imperial Brazilian, United
Mexican, and National Brazilian shares, arising from
the very favourable accounts received froni* mines'
during the week. St. John del Rey, Copiapd; Cobre,
Santiago, Linares, and Australian shares have also
chseged hands.
