FROM SOUTH AMERICA.

The New York Herald (extra( of August 2Sth,
says: We have received by the barque Mason Bar
ney, Captain Scott, which arrived at this port this
morning, accounts from Montevideo to the 81 July,
and Buenos Ayres to the 23d of June.
The Mason Barney has been north Of Egg Har-
Dor for the last six days with pilot on board.
The United States ship Plymouth, Commander
Henry, was at Montevideo, July Sd, all well. The
brig Bainbridge, Commander Pendergrast sailed
June %, for Buenos ,Ayres, having on board Mr..
Harris, the United States charge d'affaires. Cap
tain Scott, of the Mason Barney, begs to return
his thanks to Commander Henry, and the officers
Of the Plymouth, for their generous exerons in
sisting him out Of the harbor of Montevideo.
portion of the 45th regiment had embarked a
few days previous to the 81 on board vessel OF
war; destined it is said, to the Cape of Good Hope.
The 73d will remain at Montevideo.
There is no doubt but that the alliance between
the Paraguay and Corrientcs ia dissolved, and that
the treaties of lS45 no longer in force. The
Comerco de Plata expresses ignorance of the causes
Of this dissolution, and lays all the blame to the
doors of Madariaga.
In the official accounts Of the bombardment of
the convoy by the troops under Gen. Manca, it
is stated that 1860 shot, and 10000 musket cart
rides were expended by them, and 9, 500 shot. and
200 congreve rockets, by the combined forces Four
were wounded of the Rosas troops, amongst whom
was Col. J. b. Thorne. On the side Of the allies
nearly 100000 Of property was destroyed, and 80
dead bodies counted at one time upon the water
This account differs considerably from that brought
to Baltimore by the Creole
Gen. Mancilla, who, as the British Packet de-
clares is every inch man and brave soldier, has
published a letter in reply TO the dispatches of Capt
Holthan. the British commader, and after denying
point blank several Of his statements closes as fol-
lows:
GAS regards the points to which have made ref
erence, appeal to the rectitude of all the gentlemen
officers Of the anglo-French squadron, who, with as
much valor as skill, fought on that day. it being un-
derstood that if any person or persons like Captain
Hotham should dare to gainsay me, at any time, in
any place, what is said by the pen is sustained by
the sword of
GEN. MANCILLA."
The papers Of Montevideo and Buenos Ayres, OF
which we have received files contain accounts so
contradictory that it is difficult to find any news
which may be relied upon as accurate. La Gaceta
Mercant Of the latter place, confirms the accounts
concerning the brothers Madariga while the Conner
clio, Of the former place, declares that they are both
inimical to him, and friendly to Paraguay.
According to news from Entrerios the Corrientino
envoy to Paraguay had been successful in his mis-
sion; President Lopez having agreed to cancel all
the treaties that had been formed between the two
provinces in prejudice to the confederation. The
Paraguay army had Withdrawn to its own territory;
and the editor Of the Gaceta remarks: ''The impor.
tant events of Correntes show clearly to the gov
ernment Of Paraguay that nothing but disgrace can
accrue from the intrigues Of England and France
while the counsels Of the United States will con.
tribute largely towards the settlement Of all difficult
ties"
The Commerce. del Plata states that body of
Corrientinos, commanded by Flores and Montoro,
numbering nearly 1000 men, had attacked the gar
rison Of Rivera at Cabezas del ArenaI, and by them
been dsastrously routed. The dispatches of Rivera
speak Of the Corrientine army being almost to-
tally destroyed
The same paper states that Mr.. Graham. U. s.
consul, and Mr. Brent, charge d'aaires left Buenos
Ayres the Sth Of June, for either Corrientes or
Paraguay; which not known.
The appeal on behalf Of the British subjects re-
siding in, and connected with the river Plate against
any further violent Intervention by the British and
French governments, in the affairs Of that country,
is published in the papers at Buenos Ayres, and
speaks boldly Of the matters alluded to-
IL was reported that they carried messages OF
peace from Rosas TO the Corrientine and Paraguay
an governments. Other rumors gave out that they
had only left in order to deceive, and give Rosas
and UrquIza time to prepare for the next spring; but
letters received by the editor that Urquiza had
separated from the so-caed federal agreement with
Rosas, and would form league with Corrientes and
