Letters were received yes...
Letters were received yesterday from Frankfort by ex- press, (lated the 18tb inist. From these we learn that-the Teeting of Ministers at Johanoisberg had broken up, and that Prince METTEHNICH, wlhose healtli was materially improved, was about to return inimediately to Vienbla. This meeting, wbich the political alarmists throughout Europe have magnified into " a Congress on the affairs of South America," (does not appear to have assumed a re- gular deliberative character, or to have entered on any dis- cussions of genieral importanlce. InOeed, their assembling on that spot has becn entirely aceidental, owinig to the in- dispositioni under which Prince METTERNICH laboured, for which the air of Johainisberg vas prescribed byhis physiciains; and it vas out of compliment to that statesman that the major partof the foreign Ministers resident at Vienna also repaired thitlher, for the purpose of continuing the same sort of official intercourse which would have been carried on had the Prince remaiied in that city. lVe are assured that the repcrt of another meeting of Ministers at Coblentz is wholly without ioundlation.
