That by the latter, the judicial power was'not extended to private suits, in which an alien is a party, unless a citizen be the adverse party. .It was indispensable therefore. to aver the citizenship of the defendants, in order to show oh the record the jurisdiction of the court: The omission , so to do was fatal, and according to the known course of the decisions of the Court, the judgment of the circuit court must be reversed for want of jurisdiction.
