"In an action for personal injuries, where there is no assignment of error that the verdict was excessive, error in an instruction relating to the measure of damages is harmless." In support of the proposition that the trial court committed prejudicial error in its charge as to measure of damages the defendant cites Ft. Smith Western Ry. Co. v. Green, 56 Okla. 585, 156 P. 349. To hold that the case cited supports defendant's contention would be to overrule the two opinions written by Justice Turner and other opinions of this court following the rule in those cases.
