I have received the Letter which you did me the Honor to write the 3d. Instant. You there declare in the Name of Congress that the United States will be careful not to treat any other Nation in Matters of Commerce, more advantageously than the French Nation. This Declaration, founded on the Treaty of the 6th. February 1778, has been very agreeable to the King, and you, Sir, can assure Congress that the United States shall constantly experience a perfect Reciprocity in France. I have the Honor to be very sincerely, Sir, &c.
