This action was to recover for personal injuries sustained by the plaintiff, and caused, it is alleged, by a defective elevator of the defendant, which the plaintiff had occasion to use *371in the course of bis employment. The alleged defect was tbe manner in which one of the dogs used in holding up the elevator gate was attached to the gate. Various exceptions are alleged in regard to the admission of testimony, and as to the instructions to the jury, which we will consider in detail.
I. An expert upon mechanical devices, called by the plaintiff, was allowed to answer, against the defendant’s objection, this question : “ How might that dog have been fastened on so there would be no danger of the dog moving except in the natural or intended way?” We think that the question was properly allowed. The issue for the jury to pass upon was whether the defendant had used ordinary care, in view of the particular circumstances of the situation, in providing a reasonably safe elevator for the plaintiff to use in the course of his employment. It did not by any means follow that the manner of securing the appliance, which the witness might describe in his answer, was the only proper way in which it could be done, or that it was a practical or necessary way, or that the defendant was negligent in not having adopted that method. But to enable the jury to pass upon the question of whether the defendant had used ordinary care in the particular respect complained of, it was certainly proper for a qualified person to describe the way, or the different ways, that the device could have been secured so as to have been safe.
II. Counsel for defendant requested this instruction: “An employer performs his duty when he furnishes appliances of ordinary character and reasonable safety, and reasonable safety means safe according to the usages, habits and ordinary risks of the business. No man is held to a higher degree of care than the fail-average of men in the same line of business conducted under substantially similar circumstances.” In answer to which the justice presiding said: “ That is so; but what would be due care in driving a dull horse would not be in driving a locomotive.” The defendant excepts to the qualification. We think that there is nothing objectionable in this remark. It was simply an illustrative way of saying that ordinary care in any case depended upon the *372circumstances of the case; that what might be ordinary care under some circumstances would be gross negligence under others, a proposition too clear and well settled to need comment.
III. Counsel for the defendant requested this instruction: “ However strongly the jury may be convinced that there may be better or less dangerous appliances, or machinery, it should not say that the use of appliances or machinery commonly adopted by those in the same business is a negligent use for which liability should be declared or imposed.” In answer to which the justice presiding said to the jury: “Not if they (the jury) believe at the same time that it was reasonably sufficient themselves.....The common use will not of course prove its usefulness. That is evidence of its usefulness, but not conclusive.” Whereupon defendant’s counsel asked the court: “Would it not be due care to use such as is ordinarily used by persons in the same line of business ?” To which the court replied: “Yes, but that must be reasonably safe and sound; or he should use due care to have it reasonably safe and sound.” Defendant’s counsel then requested this instruction: “That he does use reasonable care when he uses the same sort of machinery that is in use in the same sort of business.” To which the court replied: “Though the jury should find that it was actually defective ? I should not say to the jury that if they found that machinery actually defective and insufficient, it would be any better because others used it.”
We think the defendant has no cause of complaint in regard to any of the rulings of the justice presiding upon the point involved in these requests. Ordinary care is such care as persons of ordinary prudence would have exercised under like circumstances. It does not depend upon custom. “ It would be no excuse for a want of ordinary care that carelessness was universal about the matter involved, or at the place of the accident, or in the business generally.” Mayhew v. Sullivan Mining Co., 76 Maine, 100.
IV. The defendant corporation was insured against accident. This fact incidentally appeared in the case because of a statement in writing from the defendant to the insurance company, which, it *373was claimed, contained certain admissions of the defendant, and was admitted only for the purpose of showing any admission of the defendant as to how and when the accident happened, and whether the defendant was using ordinary care or not. In his charge to the jury the justice presiding said: “Now it is contended by the plaintiff that they (referring to the defendant corporation) exercised no care, that they entrusted to the insurance. And there I think it admissible that it should appear that there was an insurance, or that they trusted to one rather than upon any investigation, inquiry, or experiment, or conduct otherwise of their own.”
We think that this was error; that while the fact that the defendant was insured against accidents should have no legitimate bearing, it might very naturally have an improper influence upon the jury in passing upon the one question involved, whether or not the defendant had failed to exercise that degree of care which the law required of it. The biu’deu of proving that the defendant had failed in this respect was upon the plaintiff, and we do not think that beca,use the defendant had taken the precaution to be insured against accident, that it should have any influence with the jury in determining that question. It is true that the fact of insurance might have the effect of lessening the defendant’s reason or motive for being careful. But the question was not, as to how much or how little motive the defendant had for being careful, but whether or not it had in fact exercised due and reasonable care.
We think that to allow juries, in cases of this kind, to take into consideration the fact that an employer was insured against accidents, would do more harm than good, and would increase the already strong tendency of juries to be influenced, in cases of personal injury, especially where a corporation is defendant, by sympathy and prejudice.
The only case which has been called to our attention, or that we have noticed, which at all touches this question, is that of Anderson v. Duckworth, 162 Mass. 251, in which the defendants were insured against accidents, and that fact appeared in evidence because of a conversation between the plaintiff and one of the defendants, in which, it was claimed, that there was an admission of liability and *374a reference made to the fact that the defendants were insured against accident. At the trial the jury was instructed that the fact of insurance had nothing to do with the duty of the defendants to the plaintiff or their liability to him. In the opinion of the court it is said: “And we think that it was competent for the court, in the exercise of its discretion respecting the conduct of the trial, to admit the conversation, with a caution to the jury that the fact of insurance was not to be taken as an admission by the defendants.”
It is the opinion of the court, therefore, that upon this point, the exceptions must be sustained.
Exceptions sustained.
