Postscript.—Since the above observations were written, explanations have been given by the Prime Minister in Parliament which encourage us to hope that her Majesty's Ministers have at last decided to fulfil the promises made by their late representative Mr. Mandeville, by taking effectual steps to terminate the war, and to secure the independence of the Republic of Uruguay. They have only to speak the word, and to make such a display of force as will show that they are in earnest, and Monte Video is saved. Admiral Brown, or as Commodore Purvis calls him, "Mr. Brown, the British subject, commanding the Buenos Ayrean squadron before Monte Video," will never run the double risk of being sunk by an English broadside, or of being hung as a traitor by resisting the orders of his own Government, if he is convinced that his Government means to be obeyed, and the moment that he strikes his flag, Oribe will have nothing left but to make the best terms for himself and his army. He draws all his provisions from the fleet, and must retire when his supplies are cut off.

Within the last few days information has been received from Buenos Ayres strongly confirmatory of some of the views stated above. According to letters from that city of the 7th February, the Governments of Brazil and Paraguay have formed a treaty offensive and defensive, in which they stipulate for the freedom of the rivers flowing through the territories of both. This is a movement of the greatest commercial as well as political importance, and if the independence of Monte Video is preserved, there can be no doubt that it will join this league, and that the line of communication with the interior of South America up the River Uruguay will be kept open, even if General Rosas should persist in his illegal anti-social policy of closing the Parana against foreign nations.

[C] MR. MANDEVILLE'S SUMMONS.

Buenos Ayres, December 16th, 1842.

The Governments of England and France having determined to adopt such measures as they may consider necessary to put an end to the hostilities between the Republics of Buenos Ayres and Monte Video, the undersigned Minister Plenipotentiary of her Britannic Majesty to the Argentine Confederation, has the honour, conformably to the instructions received from his Government, to inform H. E. M. Arana, Minister for Foreign Affairs of the Government of Buenos Ayres, that the sanguinary war at present carried on between the Government of Buenos Ayres and that of Monte Video, must cease, for the interests of humanity and of the British and French subjects, and other Foreigners who are residing in the country which is now the seat of war; and therefore requires of the Government of Buenos Ayres:—1. The immediate cessation of hostilities between the troops of the Argentine Confederation and those of the Republic of Uruguay. 2. That the troops of the Argentine Confederation (it being understood that those of the Republic of the Uruguay will adopt a similar course) remain within their respective territories, or return to them in case they should have passed their frontier.—The undersigned requests H. E. to reply as soon as he conveniently can, whether it is the intention of the Government of Buenos Ayres to accede to these demands, and has the honour to be, &c.

J. H. MANDEVILLE.

To H. E. Don Felipe Arana.
