Plaintiff, injured in' a collision between a wagon in which he was riding and a street car operated by defendant, claims in his petition that *332Ms injuries were caused by negligence of defendant in tlie operation of the car. The case was before us on a former appeal of defendant from a judgment of one thousand dollars, recovered by plaintiff, and we reversed the judgment and remanded the cause for a new trial (125 Mo. App. 552). We held that the evidence of plaintiff disclosed1 that negligence of his own contributed to place Mm in the way of the street car, that the evidence would support no other cause of action than one founded on a breach by defendant of its “humanitarian” duty to plaintiff and that since the petition failed to plead1 sufficiently a violation of such duty, the court erred in not sustaining a demurrer to the evidence. On the return of the case to the circuit court, plaintiff filed an amended petition stating a cause under the humanitarian doctrine. Defendant answered and the only issue of negligence raised by the pleadings and contested in the evidence was whether or not the operators of the car saw or should have seen the peril of plaintiff in time to have avoided the injury had they exercised reasonable care. The jury returned a verdict for plaintiff in the sum of five thousand dollars, and after unsuccessfully moving for a new trial and in arrest of judgment, defendant brought the case here by appeal.
Two of the instructions given at the request of plaintiff (the first and the sixth) are the subjects of adverse criticism in the brief of counsel for defendant. They are as follows:
“(1) The court instructs the jury that the defendant, in the operation of its cars on Tenth street at its intersection with Tracy avenue, possessed no rights superior to those which the plaintiff possessed in driving his vehicle along Tracy avenue at its intersection with Tenth street.”
“(6) You are instructed that if you find for plaintiff, in arriving at the amount of your verdict, you may take into consideration:
*333“First. The pain of body and mind, if any, which the evidence shows plaintiff has suffered by reason of the injury, if any, or that he will suffer in the future.
“Second. The impairment to plaintiff’s earning capacity, if any, which you believe from the evidence has resulted from such injury, if any.
“Third. Any reasonable sum of money necessarily expended or incurred for physician, nurse hire and medicines in endeavoring to be healed of his injuries, if you believe from the evidence he expended or incurred any such sum of money, but for such physician, nurse hire and medicines the amount must not exceed two hundred dollars.
“And you will allow him such a sum as you believe from the evidence will be a reasonable and just compensation for such matters, not exceeding, however, the sum of ten thousand1 dollars altogether.”
The first instruction contains nothing but the declaration of an abstract proposition of law. Such instructions should1 be avoided on the ground of their tendency to confuse and mislead the jury. The function of the jury is to decide issues of fact not to pronounce the law uor to apply the law to the facts. An instruction which fails to make application of the rule of law declared to a given hypothesis of fact is subject to the criticism that it invests the jury with the performance of a duty that does not belong to them. Frequently, however, appellate courts allow such instructions to' pass in cases where the court is satisfied that the error was not prejudicial. Such, in effect,, was the view we entertained in the recent case of Welland v. Street Railway, 129 S. W. 441.
In the present case we think the error was prejudicial. The rule declared in the instruction, though sound, was foreign to any issue of fact presented by the pleadings and evidence. The question of whether or not the street railway company had a superior or only an equal right to the use of the crossing to that *334possessed by plaintiff was discussed in our former opinion as germane to the issues of the negligence of defendant and the contributory negligence of plaintiff in the production of the perilous situation of plaintiff, but it could' have no relation to the duty of the operators of the car, under the humanitarian doctrine, to make reasonable efforts to avert the injury after they discovered, or should have discovered, that plaintiff was in peril and was ignorant of his danger. As stated, that was the only issue of fact in the case at the last trial and it was error for the court to pronounce a rule of law unrelated to that issue. The misleading effect of such error was the injection of a false issue into the case. The evidence indisputably established contributory negligence as an active factor in the production of the peril of plaintiff; nowhere in the other instructions of plaintiff was the fact of such contributory negligence admitted and the only purpose plaintiff could have had in asking the instruction was to convey to the minds of the jury the idea that it was an open question whether or not the peril of plaintiff was caused by the assertion, on the part of the operators of the car, of a superior right to the use of the crossing, and this was its obvious effect.
Further we find that in the second clause of the sixth instruction the element of damage submitted is unsupported by evidence. "What was said by the Supreme Court in the case of Davidson v. Transit C'o., 211 Mo. 320, about a similar instruction is appropriate and decisive. See, also, the opinion of this court in the recent case of Ingles v. Railway, 129 S. W. 493,--Mo. App.--. The judgment is reversed and the cause remanded.
All concur.
