The exceptions are to the admission and exclusion of evidence, to the refusals to rule as requested and to a part of the instructions.
The plaintiff clearly had the right to cross-examine the defendant’s medical expert as to the grounds of his opinion, including what took place at the examination as to her physical condition, which he conducted in the presence of her physician, and whatever was said or done at the interview was competent even if the inquiry extended to trivial details. Nor does it appear that the method or manner of cross-examination exceeded the discretionary power of the court. Jennings v. Rooney, 183 Mass. 577, 579.
If the plaintiff attempted to intimidate adverse witnesses, proof of her conduct was relevant, as being in the nature of an admission that her claim was largely groundless, but the defendant, either before or after asking the question excluded, failed to show her connection with the alleged acts of intimidation. Until this essential foundation had been laid, these questions were rightly ruled to be inadmissible.
The plaintiff’s due care not having been contested, proof of the derailment of the car in which she was riding as a passenger established prima facie the defendant’s negligence, until some satisfactory explanation was offered. Minihan v. Boston Elevated Railway, 197 Mass. 367. Carroll v. Boston Elevated Railway, 200 Mass. 527. After introducing evidence that it was without fault, -because the accident happened from causes which it could not reasonably have anticipated, the defendant presented .thirty-two requests for rulings, but only the refusal to give the twentieth request has been argued, while the other requests so far as *406they were not given have been waived. It is evident, that this request not only was substantially covered by the instructions, but having been embodied in the twenty-seventh request which was given as framed, the defendant fails to show any prejudicial error. Graham v. Middleby, 185 Mass. 349. While the eighth request was given, it furthermore appears, that the jury were correctly instructed, that unless upon all the evidence, including the fact of the derailment, with the burden of proof upon the plaintiff, they were satisfied of the defendant’s negligence she could not recover. Carroll v. Boston Elevated Railway, ubi supra.
If in the charge the judge inadvertently or erroneously stated that the testimony of the defendant’s witnesses was only in partial explanation of the derailment, upon his attention being called to the limitation, he then announced that he changed the instructions, and properly left to the jury the question, whether the explanation as the defendant contended was complete and sufficient. We are not impressed by the argument of defendant’s counsel, that the jury neither heard nor understood the modification, to which no exception was taken. The judge at the close of his instructions said, “ Now, gentlemen, that is about all the aid I can give you on this question, and we will leave it there, unless the counsel on one side or the other think I have said something I ought not to, or left unsaid something that I ought to have said,” It is to be presumed, as the exceptions contain nothing to the contrary, that the colloquy which immediately followed was in the jury’s presence and according to the usual course of jury trials. If the defendant was apprehensive that they might not have fully understood the instructions as finally left, it should have asked the judge to have directed their attention more specifically to what there had been said on this point. But not having done so, we assume that in the opinion of experienced counsel there was no reasonable ground for such a request.
The rulings throughout the trial were sufficiently favorable to the defendant, and the exceptions must be overruled.
So ordered.
