Dead body found.
--The body of a white man, attired in undress Yankee uniform, was taken from the river on Saturday, about one mile below the city, on the south side. The body was supposed to be that of one of the Yankee prisoners of war who fell overboard from the flag-of-truce steamer while it was proceeding down the river to the point of exchange. The remains were buried on the shore by the persons who discovered them.
