Williams Collins, a locomotive engineer in the employ of appellant, brought suit for personal injuries. He alleged that his injury occurred as follows: That he was given charge of an engine and caboose at Eureka Springs, Arkansas, with instructions to proceed to Berryville, Arkansas, and make up a train to Seligman, Mo. That said engine was an overhauled engine, which had never been “broken in,” as was customary after overhauling, an engine before using it, as directed. That he started with his engine, but at Kang’s Eiver bridge, he discovered that the mainpin on the right side of the engine was running hot, which was caused by a rod being keyed up too tight; that the plaintiff on the return trip from Berryville discovered at Gaskin that it was necessary to loosen a rod cup with a wrench, on account of the mainpin running hot. That in attempting to loosen said rod cup, he attached the wrench to it as is customarily done, and while attempting to loosen said rod cup, the wrench slipped and he was thrown upon his back across a large stone. That the slipping of the wrench was caused by one of the corners of said cup being round and mashed so that the wrench did not hold and that his fall was caused by reason of it slipping and that as a result thereof, he was confined to his bed for two weeks; that his left kidney was torn loose from its natural, position and badly lacerated; that he suffered much pain; and that he has since been unable to do any kind of work, or to be at ease physically; that he was permanently injured, and had suffered a decrease in his earning capacity; had lost, and would lose much time from his work; and had incurred large expense for medical treatment.
*357The answer admitted defendant’s employment, but denied all the allegations of the complaint and alleged that if plaintiff was injured, the injury resulted from his own carelessness in the performance of his work, and pleads assumption of risk.
. Plaintiff testified that he had been a locomotive engineer for six years and was operating a train, carrying goods in an interstate shipment. That when he got to King’s River’ bridge, it became necessary to stop his engine as the mainpin was running hot and to fill the cup with grease; that standing on the side of the engine on the cinder platform, he tried to unscrew the cup with a monkey wrench, but it was on too tight and he had to get the fireman to help him get the cup off with the coal pick; the fireman filled the cup with grease and they proceeded with the engine to Gaskins, where another stop had to be made to fix the hot pin. That standing again at the side of the engine, on the cinder platform, plaintiff tried at this point to unscrew the cup by pushing against the handle of the monkey wrench, but it was on too tight. Witness then changed the wrench over to the other hand so that he could put his foot against the driving wheel and pull on the wrench handle. As he pulled, the wrench slipped off the cup, and he sustained the injuries for which he sues.
One witness testified on behalf of plaintiff that plaintiff did not appear to walk as erect as he did before his injury and the nurse, who ministered to him during his confinement in bed, stated that he suffered pain and passed blood several times, and another witness testified that he had massaged appellee’s back during a period of two months; that at first it was discolored, but that there was now no discoloration or other evidence of his injury, although he still complained of a dull pain in the back.
Appellee testified that the wrench was safe, if the cup had not been round on one side, and that he did not know of this defect until after his injury, which occurred in the night time. There were witnesses, who testified *358as experts, that it was not safe to pnll on a cup with a round side with a wrench, especially when the cup was greasy, as they usually were.
It appeared to be conceded that the object of “breaking in” an engine was to see that the bearings would not run hot and time be lost in consequence; and that the failure to “break in” an engine would not endanger the safety of anyone, and the proof on the part of the defendant was that the engine had been broken in before being put back into service.
The evidence on the part of the defendant was also to the effect that the cup could be removed with safety in the exercise of ordinary care. Appellant also alleges that the verdict was excessive; and that the court erred in permitting one Dr. Tatman, a witness for appellee, to testify as to certain possible results that might arise from such an injury as plaintiff claimed to have received. In the course of the examination of this witness, the following questions and answers appear:
Q. Go ahead and state then what the natural and probable consequences of injury to the kidneys would be.
A. One of the probable results of injury to the kidneys is calculous.
Q. What other, doctor?
A. I will state the possibility of Bright’s disease. .
Q. What is Bright’s disease?
A. Chronic inflammation of kidneys, or it may be acute. In cases of this character, it may be more of a chronic type. There is practically two forms of Bright’s disease.
Q. What in reference to cure of it, chronic Bright’s disease?
A. I forget what the per cent is, but it will go up from 75 -to 90 per cent.
Q. What do the medical authorities count it as?
A. Practically incurable disease.
Q. What is calculous?
A. Stone in kidney.
Q. Is that a serious disease?
*359A. Yes.
And upon the cross examination of this witness, the following questions were asked and answers given:
Q. Yon say his spine is going to he all right?
A. Yes.
Q. And that his kidneys are practically all right now?
A. Yes, as far as I can find them now.
Q. Then you would not say that you are expecting as a natural and probable consequence of that fall that he is going to have Bright’s disease, would you?
A. Those are possible causes.
Q. That is within the range of possibility, but you are not expecting it now as a natural and probable cause, are you, doctor?
A. There is no indication of it now.
The above questions and answers, elicited on direct examination, were over the objections and exceptions of the defendant.
The court gave a number of instructions at the request of both appellant and appellee, which fairly stated the law applicable to the issues of the case, and no serious objection is urged to the correctness of these instructions, and they are therefore not set out.
But a reversal is asked for the following reasons: First, there was no negligence on appellant’s part.
Second, appellant was guilty of no negligence which was the proximate cause of appellee’s injury.
Third, appellee assumed all risk of injury attendant upon the condition of the rod cup.
Fourth, that the court erred in the admission of the evidence of Dr. Tatman, as shown above.
A. Witness, Walter Davis, who was appellant’s hostler, testified in its behalf, and on his cross-examination made the following statements:
Q. I will ask you to state whether or not it is a portion of your duty to fill rod cups with grease before the engine starts out on a run?
A. Yes.
*360Q. I will ask you also if it is a part of your duty to see that these cups and cup tops, and such things, are in proper condition?
A. Yes.
Q. I will ask yon to examine that cup (the one in question, made an exhibit to appellee’s testimony), and tell the jury whether or not that rod cup in that condition was on the engine that day?
A. It looks like if it was, I couldn’t have gotten the grease plug filled. If it was on there I never saw it.
Q. Suppose that you had discovered such a cup as that on there, what would you have done?
A. I would have took it out and put on another.
Q. I believe that you said it was your duty to observe for such defects as that?
A. Yes, sir; the contract that the engineers had was that I was to fill the grease cups, and according to their contract, the company was to fill them and I was the hostler and it was put to me to fill grease cups and replace the cups when they got in bad condition. Sometimes they got cross-threaded inside and if I find them that way, I take them out and put another on..
This evidence makes a question for the jury, both as to the defect- in the cup and the negligent failure of the master to be aware of that defect. It appears that tests were made before the jury as to whether the wrench would slip off the cup, and this cup which was sent up as an exhibit, appears to be round as described by witnesses.
Under proper instructions, submitting that issue, the jury found that the defective condition of the cup was the proximate cause of the injury.
■ Upon the question of assumption of risk, it is sufficient to say that appellee testified that he had no knowledge of the defective rod cup until after his injuries and it is not contended that he had this knowledge until after his trip had begun, and the hostler, whose duty it was to make the inspection, testified that he did not have this knowledge at all; and an expert engineer, who testified on behalf of appellant, when asked the question: “In *361the ordinary discharge of his duty, especially at night, when he came to put a wrench there, would it he so obvious that he would see that bad place there on the cup?” Answered: “I don’t think so. I know I would not. ’ ’
The ground, however, upon which appellant apparently chiefly relies for a reversal, is that the verdict is excessive and that it was made so by the erroneous action of the court in permitting witness Tatman to answer the questions set out above. We are cited to the rule announced in American and English Enc. Law, Vol. 12, pp. 449 and 450, where it is said: “A physician may give his opinion as to the permanence of certain injuries, but such opinion must not be speculative or conjectural, nor can such witness testify as to what is merely possible. Within the foregoing rule a physician is competent to give his opinion as to the natural and probable result of the disease and the probability or reasonable certainty of recovery, but it has been held improper for a physician to give his opinion as to what is likely to follow, or what sometimes results, and such an opinion was held incompetent where the witness declined to say that certain results would follow with reasonable certainty. ’ ’ But this rule was not violated here, the witness was asked certain questions, which might have led into the realm of speculation within the inhibition of the rule above, but the witness expressly stated that appellee’s kidneys were now in good condition, and that there was no indication of future trouble. The verdict in the case was for only $2,200, and of this sum, it appears that $100 was for his medical bill, and that Ms loss of time at $125 per month, the wages appellee was earmng at the time of Ms injury, would have amounted to $750, leaving the sum of $1,349 as compensation for the pain and suffering, wMch we can not say is excessive under the proof of tMs case.
Upon the whole case, we are of opinion that the verdict of the jury was warranted by the evidence and the judgment is accordingly affirmed.
