Opinion by
Mr. Justice Moschzisker,March 28, 1910:
Mary McDyer, widow of James McDyer, recovered a ver*644diet for an injury to her husband resulting in his death al leged to have been caused by the negligence of the defendant company. The defendant has appealed.
James McDyer was a milk dealer: On the day of the accident he was driving a one-horse wagon, and was accompanied by his son, a lad of seventeen. He had served a customer on the south side of a certain street, in the middle of which was a trolley line. He drove a short distance and before reaching the next intersecting street attempted to cross the trolley tracks at an oblique angle in order to get on the opposite side to serve another customer. According to the testimony of the son, immediately before crossing they stopped about three feet from the nearest rail and looked up and down the trolley line; he was listening, but did not see or hear any car; they then started across the tracks “very slowly”; when the horse had cleared the tracks and the wagon was between them, a car ran into the rear wheel; he says it was about one minute from the time they stopped and looked until they were struck by the car. The wagon was upset and pushed possibly sixty to 100 feet, McDyer being thrown out and so injured that he died about two and one-half months thereafter. Each side produced a number of witnesses, and there was much conflicting testimony, but the plaintiff’s witnesses in a general way bear out the story as we have given it. One witness for the plaintiff stated that the car was going very fast; and another that just as the team crossed the track he saw the top of the car over the crest of the hill, and that it came at a rate between twenty-five and thirty-five miles an hour. Another witness stated that the car was about 400 feet away when the horse was on the track; and a witness for the defense testified that one could see in the direction from which the car approached at least 725 feet. On this state of facts it cannot be said as a matter of law that the motorman was free from negligence, or that McDyer was guilty of contributory negligence. Both of these points were for the jury, and were properly submitted in a comprehensive charge. McDyer was not bound to stop before crossing the track, but he did so; and we have positive testimony that he looked at *645a point about three feet from the nearest rail, and that his companion listened. In the absence of testimony to the contrary, the deceased is entitled to the presumption that he continued to exercise care by looking and listening; and whether or not this presumption was overcome would be for the jury to decide on all the evidence in the case. The only other person in the wagon was produced as a witness and could have been cross-examined on this point had counsel for the defense so desired. This is not a clear case where we can say that the story told by all of the plaintiffs witnesses is impossible and the car must have been in sight when McDyer entered upon the track. A car traveling at the rate of fifteen miles an hour will cover twenty-two feet in one second: Piatt v. Pittsburg Rys. Co., 219 Pa. 583. Here we have testimony that the car was traveling at least thirty miles an hour, which would be forty-four feet in one second, or over 800 feet in twenty seconds. That McDyer had to drive slowly and with care is made apparent by the testimony, “because the rails and sills were so high it would smash your wagon to pieces if you drove fast.” Under these circumstances we cannot say that he was obliged to give his exclusive attention to the possible approach of a trolley car which was not in sight when he started to cross the tracks. Nor can we say that he must have cleared the tracks in twenty seconds or less. On the other hand, we have the testimony produced by the defendant that the trolley car could. be stopped within the distance of sixty feet, and that there was a clear view on the track of over 700 feet. On the testimony as a whole the jury may have concluded that there was no car in sight when he first entered the tracks, or that the car was then at least 700 feet away; that the motorman must have seen the wagon, and had ample time to stop if he had kept his car under proper control. If so, they had the right to find that the motorman was guilty of negligence, and that McDyer was not guilty of contributory negligence.
Much of the argument of counsel for the appellant goes to the weight of the evidence on the various points involved. Whether or not the jury properly weighed the evidence *646should have been submitted to the court below on a motion for a new trial; and this, so far as the record in the paper-book reveals, was not done.
It is complained that the court erred in overruling defendant’s objection to the question addressed to the plaintiff : “ What were the average net earnings of Mr. McDyer in a year during the time he was engaged in the milk business, per year, if you know? ” We see no error in the ruling. Although the testimony sought to be elicited, standing alone, would not have been sufficient to base an estimate of damages upon, yet the question itself was clearly relevant and competent, and the witness was in a position to give the desired information. As this is the only assignment going to the sufficiency of the evidence on the question of the proof of the damages, we will not further discuss that branch of the case.
On cross-examination as to his qualifications as a physician, Dr. Gallagher, a witness for the plaintiff, stated that he had been licensed and duly registered in Pennsylvania and his testimony was admitted without objection. He stated that he was the attending physician, and gave the details as to McDyer’s condition and ailments, expressing the opinion that the patient had died as a result of his injuries from the accident. After this, counsel for the defendant produced evidence to show that Dr. Gallagher was not a licentiate of the medical council of Pennsylvania, and that his statements to the contrary were untrue; which was followed by amotion to strike out all of his testimony.- This was refused, the trial judge stating: “The court declined to strike out the testimony of Dr. Gallagher. He was one of the physicians who attended upon Mr. McDyer, the deceased, and he was the physician de facto if not de jure. It may affect his credibility, but it would not be a warrant for the court to strike out his testimony, the fact he was not registered.” After testimony has been received without objection, the refusal to strike it out is not reviewable. In such a case the only course is to request the court to instruct the jury to disregard the testimony, and upon a refusal, to assign error: Ashton v. Sproule, 35 Pa. 492; Oswald v. Kennedy, 48 Pa. *6479; Yeager & German v. Weaver, 64 Pa. 425; Geist’s App., 104 Pa. 351. In these days when there is a possible tendency to abuse the privilege of informing the court and jury by medical experts, where one is convinced in any particular instance that the testimony from such a source is in any respect impossible, insincere or unjustified, the matter should be called to the attention of the trial judge by appropriate requests for charge, so that the court may be in a position to properly exercise discretion in submitting the evidence to the jury; but in the present case this course was not pursued. For the reasons stated the assignments going to the point in question cannot be sustained. Before leaving the subject it is but fair to say that the testimony shows Dr. Gallagher to lie a graduate of a medical school of standing in Pennsylvania and a practitioner of many years.
Several doctors were called by the defendant, and after stating that they had either heard the evidence or read the notes of testimony of the witnesses named in the following question, they were asked: “From your experience as a doctor and your knowledge of medicine, and the information you received from the evidence of Dr. Gallagher, supplemented by the evidence of Drs. Hill, Schnifferstein, and Young, do you have any fixed opinion as to the cause of McDyer’s death?" In each instance an objection to this question was sustained. All of the doctors mentioned, with the exception of Dr. Gallagher, were witnesses for the defendant, and their testimony was conflicting in many essentials with the testimony given by him. An expert witness, after being first acquainted with the whole of the particular part upon which he is to pronounce, may be asked to express an opinion upon any defined portion of the testimony, which is not contradictory in itself, and the truth of which is expressly assumed; but he may not be asked to first ascertain and determine the conflicting elements, and then to express-an opinion upon his conclusion: Yardley v.- Cuthbertson, 108 Pa. 395. As the question was framed, this is precisely what the witnesses would have been obliged to do, and for that reason the objection was properly sustained.
*648In the fifth, sixth and seventh assignments counsel for the defendant complains of three short abstracts from the charge of the trial judge. When these portions are read in connection with the charge as a whole, the criticisms made are found to be unwarranted. The plaintiff's case to a degree rests upon the presumption, to which she was entitled, that the decedent acted with care, and therefore the trial judge made no misstatement of fact in saying that the contention was that McDyer approached the track carefully, and that he listened. As this was followed by a fair statement of the contentions of the defense, and by full instructions as to the care which McDyer was bound to take in order to avoid contributory negligence, no harm could possibly have been done by the manner in which the plaintiff's contention was stated. The charge contains an ample statement of the law on the measure of damages. It is true that the abstract assigned for error simply refers to the sum total of decedent's net yearly earnings as stated in the testimony of his widow; but there was considerable other testimony in detail upon this subject which counsel could have had called to the attention of the jury had he submitted proper requests to the trial judge. Not having pursued this course, he is not in a position to complain.
Upon the whole case we discover no reversible error, and no useful purpose will be served by a further discussion of the assignments. They are all overruled and the judgment is affirmed.
