renuous efforts, as far as argument and persuasion could go, to
induce the Buenos Ayrean Government to listen to the dictates of sound
policy as well as of humanity and accept the mediation of Great
Britain and France to put an end to the war. It will grievously
disappoint the great expectations of her Majesty's Government, but for
which disappointment from my previous dispatches they will be, in a
great measure, prepared.

I have set Messrs. Ball and Diehl to work to copy the answer, that no
time may be lost in communicating it to you, and I shall send down the
Cockatrice with it the moment it is done.

Believe me, my dear M. de Vidal,

Always your sincere faithful Friend,

J. H. MANDEVILLE.

_To his Excellency D. Antonino de Vidal, &c. &c._

P.S.--Although I transmit this document to you officially,
as I feel it my duty to do, I would rather that it be not
published until we have the resolution of the Sala. In Europe,
these papers are never published until some time after they
have been delivered, which we consider as by far the best mode
of conduct.

_Buenos Ayres, October 26th, 1842_

MY DEAR M. DE VIDAL,--Neither you nor I were, nor could be surprised
at the wretchedness of our negociation, or rather of M. de Lurde's and
my attempt to make this Government accept the mediation of Great
Britain and France, to put an end to the war, and I am happy to think
that when I was last at Monte Video, I prepared her Majesty's
Government for this result.

I feel the greatest pleasure to find that my unceasing efforts to
obtain the acceptance by the Buenos Ayrean Government of our joint
mediation have satisfied you. I can conscientiously say that I have
done every thing in my power to make it succeed.

Of course I never meant but that the note should be immediately
communicated to the Government, all I requested, and in which I was
sure your own discernment and good feelings would make you concur in,
was, that it should not be published until it has come out here.

I observe, in all your letters, you write _mediation_ for mediators,
as applicable to my expressions.

"My words in one of my preceding letters were, that your reliance on
the mediators should not be vain or unfounded." This
