MY DEAR M. DE VIDAL,--My Government has seen with regret that the results of my visits to Monte Video, in December and January last, was not concession of a Treaty of Amity, Commerce and Navigation between Great Britain and the Republic of Uruguay upon the footing proposed by my predecessor Mr. Hamilton, and subsequently by me, and I have been represented as not having been sufficiently urgent with your Excellency to conclude this treaty with me, and I have been blamed in consequence. I therefore appeal to your Excellency if I did not do my utmost to induce you to negociate it with me, observing, that once concluded, it would not prejudice the acceptance of any other additional proposal on your part which might be added to it afterwards and form additional articles--and that I only desisted from urging it upon you, when I saw that my solicitations were of no avail, and you were resolved to await the answer to the proposition which I transmitted to London by your Excellency's desire. I am anxious that this circumstance should be put in its true light, and that I may be exonerated from an undeserved censure--and still more that your Excellency should commence the negociations of the treaty with me, which would be the best answer to the reports of the lukewarmness of my wishes in this business. Believe me to be, my dear M. de Vidal, with great truth and regard, most sincerely and faithfully yours, J. H. MANDEVILLE. _To his Excellency Don Antonino Vidal._ * * * * * (SECRET AND CONFIDENTIAL) _Buenos Ayres, June 18th, 1842._ MY DEAR M. DE VIDAL,--The measures which I alluded to in my private letter to your Excellency of the 10th instant--that her Majesty's Government will take for the effectual protection of the Republic of Uruguay are a joint mediation of Great Britain and France, which I am formally to tender to the Buenos Ayrean Government, upon the arrival of the French Minister here, Baron de Lurde, to adjust the difference between Monte Video and Buenos Ayres. I did not acquaint you of this important intelligence in my last letters, on account of the possibility of their falling into other hands; and as I am not to make the formal offer of joint mediation of Great Britain and France, until the arrival of the French Minister at Buenos Ayres, I think, for many reasons, which I am sure you will share with me, that it should not be made known; but I have taken the first safe opportunity of communicating it to you, for your own satisfaction and for that of your colleagues. Believe me always, my dear M. de Vidal, with great regard and esteem, most faithfully yours, J. H. MANDEVILLE. _To his Excellency M. de Vidal, &c. &c. &c._ * * * * * _Buenos Ayres, June 23d,1842._
