opinion: Per Curiam.
  The judgment of the District Court is reversed and the case is remanded for consideration by that court of the only claim that was left open at this Court’s prior disposition of this litigation, to wit, whether “the preferred stock issue as approved by the [Interstate Commerce] Commission was in violation of the Interstate Commerce Act.” Alleghany Cory. v.
