The jury in answer to the first interrogatory propounded under the special verdict pursuant to Rule 49(a), Fed.R.Civ.Proc., 28 U.S.C., found the respective Lincoln Continental automobiles were “fit for the ordinary purpose for which automobiles are used.” In view of this fact it makes no difference that the court did not charge with respect to express warranty. We perceive no error in the record prejudicial to the plaintiffs' causes. Consequently, the judgments will be affirmed.
