THE PLATE.

By the withdrawal of General Urquiza to the
province Entre Rice, of which he is governor, the
siege of Buenos Ayres has come to an end, since
the departure of last packet. By this event peace
was restored to the province, and commercial trans-
' actions we again resumed. M. Pastor Obligado
had been appointed Provisional-Goversor and Cap-
tain-General of Buenos Ayres.
The published reports of the proceedings in the
House of Representatives show that the present
rulers of Buenos Ayres do not feel full confidence
in the permanence of their bought tranquillity.
Senor Auchorena, who was twice elected governor
of the province, twice resigned, and the present
governor resigned once on account of the difficulty of
torining a ministry.

On the 13th, before leaving, General Urquiza
transmitted th 3 following note to the government of
Buenos Ayres :
Viva la Confederacion Argentina!
The Provisional Director of the Argentine Confederation.
San Jose de Flores, July 13, 1653.
To the Ministers of Government of Buenos Ayres, charged

with the Executive Power.

I have the honour-of addressiagthCiiinisters, who at
present conduct the government of Buenos Ayres, to ac-
quaint them, that the question which divided this province
from the rest of the Confederation having been decided by
the last sanctions of the Constituent Congress, I have
resolved to retire from its territory with the National Con-
tingents.
Upon-this basis it would be convenient for all, and highly
honourable to the Argentine name, that the government of
Buenos Ayres should coniant and acknowledge to be at
peace with the rest of the Confederation, and it would afford
me much pleasure to receive a communication to that effect.
Clod preserve your Excellencies many years.
JUSTU .101311 DI URCIVIZA.

Sir Charles Hotham left Buenos Ayres on the 26th
instant, in her Majesty's steamer Trident, supposed
for England, via Monte Video. Ilia departure and
embarkation were strictly private, and without offi-
cial etiquette.

LOSS OF THE MAIL STEAMER QUITO.

The Panama Herald of Aug. 18, says : "Yesterday
eveniag, about 4 o'clock, the steamer Uncle Sam anchored
in our bay, having left New York on the 20th June, conse-
quently making the passage ia 58 days, or deducting nine
days' detention at Rio and Valparaiso, in 49 running days,
being one day less time than the celebrated trip of the
Cortes.
" She brings news of the total loss of the P. S. N. Cds
splendid steamer Quito, Captain Wood, to the north of
Valparaiso, owing to her having mistaken the entrance to
the port of lluasco.
" We have received a letter from a friend, who was
on board at the time of the accident, from which we
make the following extracts :—'l was detained twelve
days on my voyage, owing to the loss of the beautiful
steamer Quito, which was wreck,d on the night of the
10th, on Point Loboa, owing to the captain having mis-
taken a small bay for Reese., lying twelve miles north of
that port, and not discovering his mistake until too late to
prevent his ship from running on the rocks.

CHOLERA AT NEWCASTLE.

Fri r. 13.—W new cues; 37 deaths.

. _
lie returns from Gateshead are incomplete, but
the a,e oit,t of the clerk to the guardians gives 44 as
the:,'al of deaths up to Tuesday. A very general
.1.• el tendency prevails, and the druggists'
1,10p4 and surgeries or the parochial medical officers
gre lq ported to be " besieged" with applicants for
medicine to counteract looseness of the bowels. The
b 'Ards of guardians arc active, and have appointed
extra medical aseistat.ts. The Poor Law luspector
has been directed to proceed to Newcastle, and act in
aid of the parochial authorities. Many of the cases
are described is frightfully rapid. General instruc-
tions have been issued by the guardians, both at
Newcastle and Gateshead, impressing on the public
the importance or prompt attention to diarrhees.
Depots for the supply of medicine free of charge
have been opened, and the assistance of senior me•
ducal students has been secured, with a view to
house to house visitation of the affected districts.
There is a general agreement among the medical
Fat :itioners that the epidemic is to be met and con.
trolled in the stage of premonitory diarrhea: and
that this is only to be done effectually by house to
house visitation of the localities where that is most
prevalent, and its progress checked. Much diarrhoea'
has been found.

LEmus.—The mayor of Leeds has issued a circu-
lar. calling attention to the progress of the cholera
we.twards, and urging the reorganisation of district
ascitary. committees, sod other preeautioaary mea-
sures. with a view to check its progress, should it
reach Ueda.
