SIR,--I was honored, on the 2d instant, with the receipt of your favor of March the 15th, enclosing the resolution of Congress of the 10th of the same month, appointing me their Minister Plenipotentiary at this court, and also of your second letter of March 22d, covering the commission and letter of credence for that appointment. I beg permission through you, Sir, to testify to Congress my gratitude for this new mark of their favor, and my assurance of endeavoring to merit it by a faithful attention to the discharge of the duties annexed to it. Fervent zeal is all which I can be sure of carrying into their service, and, where I fail through a want of those powers which nature and circumstances deny me, I shall rely on their indulgence, and much also on that candor with which your goodness will present my proceedings to their eye. The kind terms in which you are pleased to notify this honor to me, require my sincere thanks. I beg you to accept them, and to be assured of the perfect esteem, with which I have the honor to be, Sir, your most obedient, and most humble servant, TO GENERAL CHASTELLUX. PARIS, June 7th, 1785. DEAR SIR,--I have been honored with the receipt of your letter of the 2d instant, and am to thank you, as I do sincerely, for the partiality with which you receive the copy of the Notes on my country. As I can answer for the facts, therein reported, on my own observation, and have admitted none on the report of others, which were not supported by evidence sufficient to command my own assent, I am not afraid that you should make any extracts you please for the Journal de Physique, which come within their plan of publication. The strictures on slavery and on the constitution of Virginia, are not of that kind, and they are the parts which I do not wish to have made public, at least till I know whether their publication would do most harm or good. It is possible, that in my own country, these strictures might produce an irritation, which would indispose the people towards the two great objects I have in view; that is, the emancipation of their slaves, and the settlement of their constitution on a firmer and more permanent basis. If I learn from thence, that they will not produce that effect, I have printed and reserved just copies enough to be able to give one to every young man at the College. It is to them I look, to the rising generation, and not to the one now in power, for these great reformations. The other copy, delivered at your hotel, was for Monsieur de Buffon. I meant to ask the favor of you to have it sent to him, as I was ignorant how to do it. I have one also for Monsieur Daubenton, but being utterly unknown to him, I cannot take the liberty of presenting it, till I can do it through some common acquaintance.
