Two of appellant’s contentions may well be considered together. The first is that there was no sufficient evidence of any protest or objection by the plaintiff against continuing to work with the defective locomotive to carry the question to the jury, and therefore a verdict should have been directed in defendant’s favor. The other contention is that the instruction given to the jury on this subject was erroneous. The conditions under which an employee may knowingly continue to work with a defective and dangerous appliance, in reliance upon a promise to repair, have been many times stated, and ought not to be in serious doubt. Judge Cooley (Torts, p. 559) states the rule:
“ If the servant, having a right to abandon the service because it is dangerous, refrains from doing so in consequence of assurances that the danger shall be removed, the duty to remove the danger is manifest and imperative} and *188the master is not in the exercise of ordinary care unless and until he makes his assurances good. Moreover, the assurances remove all ground for the argument that the servant, by continuing the employment, engages to assume its risks.”
In Stephenson v. Duncan, 73 Wis. 404, 407, this court said:
“ Where the servant, having the right to abandon the service because it is dangerous, refrains from doing so in consequence of assurances by the master that the danger .shall be removed, such assurances remove all ground for holding that the servant, by continuing in the employment, engages to assume the risk.”
In Erdman v. Illinois S. Co. 95 Wis. 6, 12, in dealing with an alleged continuance at work in reliance on a promise to remove the danger, we said:
“At the threshold of this question there is the essential element of protest or objection to proceed with the work on account of the danger.”
Other cases on the subject: Sweet v. Ohio C. Co. 78 Wis. 127; Maitland v. Gilbert P. Co. 97 Wis. 476, 484; Jensen v. Hudson S. Co. 98 Wis. 73; Curran v. A. H. Stange Co. 98 Wis. 598.
From these cases it is apparent that the assumed willingness of an employee to continue work with the appliances supplied him, at his own risk, must be negatived, and it must be made apparent that the master or those representing him understand he is not so willing. Further, such unwillingness, brought to the knowledge of the master, may and must be overcome temporarily by a promise to remove the danger within a reasonable time. Appellant’s counsel seems to contend in his brief, though not so obviously in oral argument, that there must be a direct threat to quit work unless the repairs be made. This is not essential. Indeed, there may be cases where not even a spoken word from the employee is necessary, if it is apparent that the •master or those representing him understand that a state of unwillingness and objection exists, and that such unwillingness is overcome by the promise of repair. The very man*189ner of making the promise may well indicate the understanding of the master that such unwillingness and mental protest does exist. That fact must appear, however; for it cannot be said that one refrains from abandoning service because of a promise, if it were not also true that but for that promise he would abandon it, and one cannot be said to continue in a perilous employment by reason pf a promise if he were not otherwise unwilling so to do. Hence the-rule tersely suggested in the Erdman Case is undoubted, that the master must be given to understand that the servant protests and objects against continued exposure to the danger. If, so understanding, he promises to remove it, the servant is justified in temporarily continuing the employment until such reasonable time has elapsed as to destroy his right to rely upon the promise to repair, except, in certain cases of peculiarly great, imminent, and unavoidable danger, of which more hereinafter. The master meanwhile is responsible for such injuries as are proximately caused by the defect, without contributory negligence.
In this case the plaintiff first entered in a book a notification of the defect and need of repair, which book was an ordinary medium of communication between himself and his immediate superior. This act alone might, as counsel for appellant argues, be ambiguous. It might convey no-intimation of plaintiff’s unwillingness to expose himself to the peril of the defect, but merely an intention to perform a duty of notifying the master, in order that it might, for its own purposes, make repair. The further conversation between the plaintiff and the yard master, and also between the plaintiff and the yard master and the roundhouse foreman, is much more significant. It was addressed to the latter, to whom plaintiff had no right to give orders or directions. . The roundhouse foreman remarked that the step in. question was not very bad, to which Yerkes responded, evidently with considerable emphasis: “"Well, it is bad enough,. *190and I want it fixed; I consider it unsafe.” We think this language certainly capable of being understood by those representatives of the master as expressing a state of protest and objection against further exposure to this dangerous condition. The words, “I want it fixed,” “it is unsafe,” could hardly be attributed to anything but such state of mind. Plaintiff had no right to express a command or direction to either of the others. They and he well understood that the only alternative within his control was to quit if. his wish were not complied with. To express such wish was idle, unless some result were to follow refusal, but his manner and words were evidently inconsistent with mere futility. We think they might well convey to his hearers a purpose to act for his own protection if they would not. That they were so understood by the representatives of the master is clearly shown by the interview of the evening, when the engine was again brought out from the roundhouse. Plaintiff then said to the yard master, “There is that damn footboard now, and it hasn’t been fixed.” To this statement the yard master replied, “Use it to-night, Oharley, and I will see that it is fixed to-morrow.” These words would have been in no wise responsive to the plaintiff’s remark, except as the latter was understood to convey the idea of protest against'working with this device. We are satisfied that these conversations and declarations of the plaintiff were sufficient to carry to the jury the question whether he was protesting and objecting.
The instruction to which exception was taken was in the following words: “In other words, the general rule is that the servant assumes all ordinary risks of his employment, and if any defect in the tools, implements, or appliances is called to the attention of the employer, and the employer agrees to repair such defect, the employee may rely upon it, and continue his employment on the strength of the promise to repair, provided it is done within a reasonable time.” *191This instruction, is clearly bad, in that it does not insist upon the element of protest and objection above discussed. It would be satisfied although the servant called the defect to the attention of his master under circumstances in no wise implying or indicating that he was unwilling to. continue working with it in its then condition. In so far it was misleading, improper, and erroneous. True, in the same paragraph the court made another statement of the rule, in which he described the duty of the employee as to notify the employer of a special risk and object to continuing the •work under the then existing conditions, but we cannot hold that thereby the vice in the portion excepted to was cured. The court attempted, apparently, to phrase the same rule twice. In so doing he expressed it once correctly, but again erroneously. It is well settled in this state that an erroneous instruction on a given subject is not cured by the fact that the law is correctly stated elsewhere; for it cannot be known whether the jury have been guided by the correct rule or by the erroneous one.
2. Appellant further contends that a verdict for the defendant should have been directed, and, one for plaintiff having been rendered, it should have been set aside, for the reason that the peril from the bent and slanting footboard was so obvious and imminent as to make serious injury so probable that plaintiff could not, consistently with reasonable care, expose himself to that peril, even temporarily and for a reasonable time, until the promise of repair was performed; resting mainly upon Erdman v. Illinois S. Co. 95 Wis. 13. That case stated a rule of law applicable to the liability of master to servants, well supported in reason, salutary and proper in a case falling within it, such as that presented on that occasion, where a mechanic, with full knowledge of the peril, placed himself in front of a saw revolving 1,100 times a minute, which he knew to be cracked, and attempted to saw bars of iron therewith. The continued *192increase of the fissure in the saw was certain. It was obvious that the saw must very soon, and. might at any moment, fly into fragments; that when it did so very serious injury to him was certain; and that no exertion or precaution on his part could protect him therefrom. That case was followed by Maitland v. Gilbert P. Co. 97 Wis. 485, wherein the opinion was written by Mr. Justice Marshall, and the case was distinguished from the Erdman Case in the following words:
“ Here Welk was working under the immediate supervision of plaintiff. It is by no means conclusive that the circumstances were such that plaintiff may not reasonably have supposed that he could so supervise Welk’s conduct as to temporarily avoid any serious danger of his presence as a co-employee.”
The same distinction was pointed out in Curran v. A. H. Stange Co. 98 Wis. 606. See, also, Jensen v. Hudson S. Co. 98 Wis. 73; Nelson v. Shaw, 102 Wis. 274, 278. From these authorities it results that it cannot be said as matter of law that one is so guilty of contributory negligence in continuing to work, even temporarily, with a known defective ap-plianee, after a promise of repair, if an ordinarily prudent person, under like circumstances, might reasonably believe and expect that by the exercise of some extra care and precaution he could avoid and avert the threatened peril. We think the facts in this case might well support such a conclusion by a jury. While it is undisputed that the step in question, ten inches in width, was bent down at one corner so that the outer edge was from two to three inches lower than the inner edge, yet the engine was provided with a handhold by means of which one could protect himself from falling. It had been used for at least two nights before this promise of repair, both by the plaintiff and by his. helper, and no accident had occurred. Evidently it was the opinion, both of his superior, the yard master, and of the roundhouse foreman, that it might be used without serious. *193and imminent peril, and that such use was not unreasonable. We cannot say that there was no evidence which, most favorably viewed, might support the inference drawn by the jury that the peril was not so imminent, so constant, and so unavoidable but that a reasonably prudent man might, without negligence, continue to use it pending the fulfilment of the promise to repair. That question was submitted under an instruction expressing the rule of the Erdman Case with at least sufficient stringency against the plaintiff.
3. Plaintiff assigns as error the definition of the due care which plaintiff was bound to exercise to avert the charge of contributory negligence, viz.:
“ The plaintiff cannot recover in this case unless you find that he was in no manner guilty of any want of ordinary care, or such care as persons of ordinary care ordinarily use, which contributed to his said injuries.”
That this was an incorrect and misleading definition of “ ordinary care ” has been declared so often by this court as to make further discussion unnecessary. The rule has been repeatedly laid down that due care is to be tested by the surrounding circumstances, and that no definition is complete or correct which does not embody that element. Ordinary care is the care ordinarily exercised by the great mass of mankind, or its type, the ordinarily prudent person, under the same or similar circumstances, and the omission of the last qualification, “ under the same or similar circumstances,” or “ under like circumstances,” is error. Boelter v. Ross L. Co. 103 Wis. 324, 330; Dehsoy v. Milwaukee E. R. & L. Co. 110 Wis. 412; Warden v. Miller, ante, p. 67. The necessity of the omitted qualification to a correct definition of due care is especially obvious under the circumstances of this case. What would be the care of an ordinarily prudent person, standing in safety upon a stationary platform, or even standing upon the perfect and level footboard of a *194moving switch engine, would not be the care to be expected of one attempting to perform the services of a yard man upon a bent, declining, and defective footboard such as here presented. The attention of the jury was not called by this-instruction to a very important element which they must consider in order to decide whether the plaintiff was or was not guilty of contributory negligence, and the instruction to them on the subject was therefore misleading and erroneous.
Since, by reason of the two errors already pointed out, this cause must be reversed and remanded for a new trial, it is perhaps not necessary to discuss fully some of the other assignments of error. It may be well, however, to notice the instructions with reference to damages for future suffering and impairment of ability. The court instructed that, in case the jury found the injuries to be of a permanent character, they should assess “ such damages for physical and mental suffering as he will be compelled to undergo in the future, and for future loss of time, but can only assess such damages as you find from the evidence the plaintiff has actually sustained and will actually sustain if his injuries are permanent.” That there was evidence to justify the jury in finding permanent injury and future suffering we have no doubt. The loss of a limb of course impairs one’s efficiency, comfort, and enjoyment of life, and in this case there was evidence of a stubborn resistance to complete healing of the wound resulting from amputation. The elements in the instruction which are criticised are the two expressions, “ as he will be compelled to undergo,” and “ will actually sustain.” We cannot discover in these anything injurious to the defendant, for they seem to require a higher degree of certainty of such injury than is justified by the law. The rule has been many times stated that a plaintiff is entitled to recover damages for such suffering and such impairment of abilities as he is reasonably certain to endure as *195the result of his injuries. This measure of certainty should he required of a jury, and not a different one, which may or may not be its equivalent.
Error is also assigned upon the overruling of objections to certain questions to witnesses. The court, over defendant’s objection, asked the question of the plaintiff: “ How did it happen that you remained there and used that engine after — worked on that engine — after you noticed the condition it was in? A. I stayed there and worked because they had promised to fix it.” The plaintiff was then asked by his counsel, “Would you have worked on that engine after you discovered the condition it was in thére, if they had not promised to repair it? ” to which, after objection, he answered, “I would not.” These questions were objected to because they called for the conclusion of the witness. The first of them is unobjectionable. It is but testimony of the plaintiff to his mental processes. It differs not at all from the question usually propounded in actions of deceit, whether or not the defrauded party believed and relied on the fraudulent statement, and whether he was induced to act thereby; and while such evidence is, at best, of but little weight, as said in the Erdman Case, 95 Wis. 12, it is admissible. Curran v. A. H. Stange Co. 98 Wis. 606; Great Northern R. Co. v. McLaughlin, 17 C. C. A. 330, 333. The second question, whether plaintiff would have worked on the engine but for the promise, is objectionable in form. So far as it goes only to the proposition that he relied on the promise and was induced thereby to work, it is in parity with that asked by the court; but in form it calls for the opinion of a witness as to what his conduct would have been in an hypothetical case,— a form of question which has been held improper very often. Woodworth v. Mills, 61 Wis. 44, 54; Commercial Bank v. Firemen's Ins. Co. 87 Wis. 297, 303; Hill v. American S. Co. 107 Wis. 19, 29.
The last assignment of error, predicated upon alleged ex*196cessive award of damages, cannot be sustained, in the light of Berg v. C., M. & St. P. R. Co. 50 Wis. 419. In that case the permanent injury was quite similar to plaintiff’s, but the earning capacity of Berg was less than one third of Yerlees’s. The recovery in this case would purchase for the plaintiff an annuity of but little more than half of his yearly earnings at the time of his disablement. While the damages are large, we cannot say that they are beyond reason, or necessitate an inference of passion or prejudice.
The two errors in charging the jury above indicated render reversal unavoidable.
By the Court.— Judgment reversed, and cause remanded for a new trial.
