The Fenians.
New York, December 10.
--John O. Sullivan, signing himself "late Centre from Ireland." has sent a card to the newspapers stating that William R. Roberts, now President of the Fenian Senate, declared to him that he would destroy the present organization and substitute a new one in its place; and others of the Senators, whose names are published, asserted they would tear down the present brotherhood and erect one suited to themselves.
He says the Irish recognize O. Mahoney as the chief head.
