I have the honor to lay before Congress two letters from Messrs de Neufville and Son, under cover of which last I received the enclosed letter, which contains what I suppose to be the first sheet of Mr Dana's letter, probably sent immediately after he had discovered his mistake. I send the other parts with it. I also enclose for the perusal of Congress an act of the British Parliament for the exchange of American prisoners, which, when returned to the office I shall have published.

I find in a Leyden paper some account of Mr Grenville's negotiation, and the alterations proposed by the committee of the States General to the treaty submitted to their consideration by Mr Adams. These may be objects of curiosity, and as such I enclose them. They will be printed on Saturday if the papers are returned in time.

A Dutch paper of the 13th of July, mentions that the Baron Vioménil, the Marquis de Lavall, and other officers, left Paris the beginning of July, in order to sail in the —— frigate; that the Marquis de Lafayette was not to accompany them, as it was proposed; that he was waiting the issue of the negotiation in Paris.

The Count D'Artois has obtained leave of the King of Spain to serve as a volunteer at the siege of Gibraltar. This may perhaps be concluded as an indication of their hope of success in the attempt to reduce it.

I have the honor to be, &c.

ROBERT R. LIVINGSTON.

TO THE PRESIDENT OF CONGRESS.

Philadelphia, September 12th, 1782.

Sir,

I have the honor to enclose two reports upon Mr Adams's letters. I would propose in addition to the first to direct the substance of Mr Adams's letter of the 23d of April, containing his note, and the appointment of a committee, to be printed as articles of intelligence, not under the express direction of Congress, since the business is not concluded.
