Grosvenor Square, December 16, ...824 Mr. Jay's letter of the 16th October received, with its enclosures. Is honored by the approbation of Congress. Mr. Smith will return to New York. Approves of the new plan of Government. Hopes to hear of its being adopted by all the States. Rumor of a quadruple alliance in Europe. America nothing to fear, except a want of union and government. No answer from the Ministry to any letters or memorials. None expected.
