Note 15 — LETTER IX. To R. Cooper, Esq., Cooperstown.

Mr. Adams, in his Eulogy on La Fayette, has called the duc de Noailles, the first peer of France. The fact is of no great moment, but accuracy is always better than error. I believe the duc de Noailles was the youngest of the old ducs et pairs of France. The duc d’Uzés, I have always understood was the oldest.
