I have the honor to be, with the most perfect esteem, Sir, your most obedient and most humble servant, Th: Jefferson. LETTER XXV.--TO THE COUNT DE FLORIDA BLANCA, April 11, 1790 TO THE COUNT DE FLORIDA BLANCA. New York, April 11, 1790. Sir, The President of the United States having thought proper to name Mr. William Carmichael their _chargé des affaires_, near his Catholic Majesty, I have now the honor of announcing the same to your Excellency, and of praying you to give credence to whatever he shall say to you on my part. He knows the concern our republic takes in the interest and prosperity of Spain, our strong desire to cultivate its friendship, and to deserve it by all the good offices which esteem and neighborhood may dictate; he knows also my zeal to promote these by whatever may depend on my ministry. I have no doubt that Mr. Carmichael will so conduct himself as to merit your confidence; and I avail myself with pleasure of this occasion of tendering to you assurances of those sentiments of respect and esteem, with which I have the honor to be, your Excellency’s most obedient and most humble servant, Th: Jefferson. LETTER XXVI.--TO WILLIAM CARMICHAEL, April 11, 1789 TO WILLIAM CARMICHAEL. New York, April 11, 1789. Sir, A vessel being about sail from this port for Cadiz, I avail myself of it to inform you, that under the appointment of the President of the United States, I have entered on the duties of Secretary of State, comprehending the department of Foreign Affairs. Mr. Jay’s letter of October the 2nd acknowledged the receipt of the last of yours which have come to hand. Since that date he wrote you on the 7th of December, enclosing a letter for Mr. Chiappe. The receipt of his letter of September the 9 th, 1788, having never been acknowledged, the contents of which were important and an answer wished for, I send you herewith a duplicate, lest it should have miscarried. You will also receive, herewith, a letter of credence for yourself, to be delivered to the Count de Florida Blanca, after putting thereon the proper address, with which I am unacquainted. A copy of it is enclosed for your information.
