My last letter to you was of the 6th instant, acknowledging the receipt of your favors of the 2nd and 6th of January. Since that, Mr. Jay has put into my hands yours of the 12th of January, and I have received your note of February the 10th, accompanying some newspapers. Mine of the 6th covered the President’s letter to the King for my recall, and my letters of leave for myself and of credence to you, for the Count de Montmorin, with copies of them for your information. Duplicates of all these accompany the present; and an original commission for you as _chargé des affaires_, signed by the President. At the date of my former letters, I had not had time to examine with minuteness the proper form of credentials under our new constitution: I governed myself, therefore, by foreign precedents, according to which a _chargé des affaires_ is furnished with only a letter of credence from one minister of Foreign Affairs to the other. Further researches have shown me, that under our new constitution, all commissions (or papers amounting to that) must be signed by the President. You will judge whether any explanation on this subject to M. de Montmorin be necessary. I enclose you also the copy of a letter written to the Marquis de la Luzerne, to be communicated to the Count de Montmorin, and by him to the King, if he thinks proper. It has become necessary to determine on a present proper to be given to diplomatic characters on their taking leave of us; and it is concluded that a medal and chain of gold will be the most convenient. I have, therefore, to ask the favor of you to order the dies to be engraved with all the despatch practicable. The medal must be of thirty lines diameter, with a loop on the edge to receive the chain. On one side, must be the arms of the United States, of which I send you a written description, and several impressions in wax to render that more intelligible; round them, as a legend, must be ‘The United States of America.’ The device of the other side we do not decide on. One suggestion has been a Columbia (a fine female figure), delivering the emblems of peace and commerce to a Mercury, with a legend ‘Peace and Commerce’ circumscribed, and the date of our republic, to wit, IV July ‘MDCCLXXVI,’ subscribed as an exergum: but having little confidence in our own ideas in an art not familiar here, they are only suggested to you, to be altered, or altogether postponed to such better device as you may approve, on consulting with those who are in the habit and study of medals. Duvivier and Dupre seem to be the best workmen; perhaps the last is the best of the two. The public papers, which accompany this, will give you fully the news of this quarter. I am with great and sincere esteem, Dear Sir, your most obedient and most humble servant, Th: Jefferson. LETTER XXX.--TO MR. DUMAS, June 23, 1790 TO MR. DUMAS. New York, June 23, 1790. Dear Sir,
