Mr. Justice Scanlan delivered the opinion of the court.
2. Instructions, § 82*—when instruction as to credibility of testimony of one party improper. Where both plaintiff and defendant testify in the suit, an instruction to consider the interest of the plaintiff in giving credence to her testimony, without any reference to the interest of the defendant, held calculated to impress the jury that the court entertained a special reason for discrediting the testimony of plaintiff. 3. Instructions, § 59*—when instruction as to relative rights of defendant and third party misleading. In an action for personal injuries alleged to have resulted from the negligent driving of a wagon, an instruction given for defendant with reference to the relative rights of defendant and the street railway company as to the use of the street at the place of the accident, held, misleading where the street railway is not a party to the action. 4. Damages, § 209*—when instruction limiting damages to sum received by plaintiff in consideration of dismissing suit against party made codefendant prejudicial. In an action for personal injuries where the action was originally .commenced against the defendant and a street railway company, but plaintiff in consideration of two hundred dollars entered into a peace covenant as to the railway company and dismissed the action as it only, an instruction given for defendant that the jury must find for defendant in case the damages sustained were not in excess of the two hundred dollars received by plaintiff from the railway company, held erroneous and prejudicial.
