November 19th.—I rarely sat down to write under a sense of greater responsibility, for it is just possible my letter may contain the first account of the seizure of the Southern Commissioners which will reach England; and, having heard all opinions and looked at authorities, as far as I could, it appears to me that the conduct of the American officer, now sustained by his Government, is without excuse. I dined at Mr. Corcoran’s, where the Ministers of Prussia, Brazil, and Chili, and the Secretary of the French Legation, were present; and, although we did not talk politics, enough was said to show there was no dissent from the opinion expressed by intelligent and uninterested foreigners.
