PER CURIAM.
The motion of appellee to dismiss the appeal from an order of the District Court granting separate trials of the issues raised by the complaint and the third-party complaint is hereby granted on the ground that the order sought to be reviewed is not a final appealable order, but is an interlocutory order relating to a collateral matter not involving an extraordinary situation. Kowalski v. Holden, 6 Cir., 1960, 276 F.2d 359; McPherson v. Hoffman, 6 Cir., 1960, 275 F.2d 466 and Regec v. Thornton, 6 Cir., 1960, 275 F.2d 801.
