Leteher, of Virginia, has opcnlv leehired in favor of Douglas. Tho domocraey west of Iho Bluo iidííe is almost unanimously aguinst he seeeders. Ex-Govornor Wisc is ptill is doubt vhether he shall support Breckinridge, ■üthough bis name is on tho Charlotcsvillo sccedcrs' electoral ticket. Not only tho national committco, bat Mr. Douglas himself, siietains Co!. Fornoy in liis opposition to tho Jireckoridgo fusión ticket in Pennsylvanin. Havinguuitod vvith the Union party, any amalgamatiou wiih thü soceders willbe con8idered a breach óf contract. Mr. Breckinridge, bcing without a shadow of sucwra in the North, wfll oertainly be íor.saken by the conservativo portion of the Bontbern democracy. Tlio idministration ia determinod not to permit Spain to inako war upon Mesico; at loast not to altaoV thelatter upon itsown land, and take possession oí it. Mr. Buchanan ih willing to act as mediator, bot he vvill not pennit that tho Monroo doctrino, which owes its origir. to the aggrossions of Spain, shall be disregarded.
