DEAR SIR,--Uncertain whether you might be at New York at the moment of Colonel Franks' arrival, I have enclosed my private letters for Virginia under cover to our delegation in general, which otherwise I would have taken the liberty to enclose particularly to you, as best acquainted with the situation of the persons to whom they are addressed. Should this find you at New York, I will still ask your attention to them. In my letter to Mr. Jay, I have mentioned the meeting of the Notables, appointed for the 29th instant. It is now put off to the 7th or 8th of next month. This event, which will hardly excite any attention in America, is deemed here the most important one which has taken place in their civil line during the present century. Some promise their country great things from it, some nothing. Our friend de La Fayette was placed on the list originally. Afterwards his name disappeared, but finally was reinstated. This shows that his character here is not considered as an indifferent one, and that it excites agitation. His education in our school has drawn on him a very jealous eye from a court whose principles are the most absolute despotism. But I hope he has nearly passed his crisis. The King, who is a good man, is favorably disposed towards him, and he is supported by powerful family connections and by the public good will. He is the youngest man of the Notables except one whose office placed him on the list. The Count de Vergennes has within these ten days had a very severe attack of what is deemed an unfixed gout. He has been well enough, however, to do business to-day. But anxieties for him are not yet quieted. He is a great and good minister, and an accident to him might endanger the peace of Europe.
