delivered the opinion of the court.
This case has been tried twice. On the first trial there was a judgment for the plaintiff, O. O. Bell, which was reversed by this court in accordance with an opinion reported in Virginian R. Co. v. Bell,
The main facts in the case sufficiently appear from the former opinion. It will be sufficient here to state that the plaintiff was a railway, mail clerk and claims to have been struck and injured by a sliding door to the car in which he was at work; and that the principal act of negligence relied upon by him was the alleged failure of the defendant company to provide a reasonably safe hook or fastener to hold the door open when an exchange of mail was to be made.
1. The first assignment of error is based upon the action of the court in refusing to set aside the verdict of the jury as
■" We do not- think the ease can be controlled by the decision of this court in C. & O. Ry. Co. v. Anderson,
It is further urged in support of the contention that the evidence did not warrant the verdict, that there is no reasonable probability that the plaintiff would have used the hook if it had been on the door, and, furthermore, that he was guilty of contributory negligence in not holding the door open with his hand or foot. The counsel for the defendant company have presented the argument upon these propositions very forcibly, but we cannot consider the wéight of the evidence or the credibility of the witnesses,, and we are of opinion that both as to the probable use of the hook, and as to the contributory negligence of the plaintiff, there was enough in the evidence to carry these questions to the jury. Moreover, it was held by this court at the former hearing of this case (
' It follows from what has been said that the first assignment of error must be overruled.
2. The witness, Dr. E. 0/ Ambler, was permitted, over the
The question under consideration was improper as a hypothetical question, because it assumed that the plaintiff’s neck was against the door jamb when there was no proof of that fact. Moreover, it was not a sudden stop, but only a more or less sudden reduction of the speed of the train, which is claimed to have caused the injury, and the question was inaccurate and misleading in this respect. It was further improper because the only matter of expert knowledge upon which the witness could properly express an opinion was as to the force necessary to cause the fracture, which is very different from the question as to how violent would be the blow from a door of given size and weight upon the application of air brakes on a train running at a given rate of speed. As a physician, Doctor Ambler could properly express an opinion in answer to the former but not the latter question, unless he was an expert on dynamics as well as on anatomy and surgery. He testified
In McCue’s Case,
In the case at bar, the elements involved in determining the force of the blow were not only not matters of common knowledge and experience, hut matters with which the witness said he was unfamiliar, and as to which, in the main, there was a sharp contention. The objection to the question and answer was earnestly pressed, and the incompetency of the witness to speak upon the subject was clearly brought out in the trial court, and the objection should have been sustained.
There were other assignments of error, but we regard them as subordinate and not such as to require discussion.
For the errors pointed out, the judgment will be reversed, the .verdict set aside, and the same remanded for a new trial.
Reversed.
