delivered the opinion of the court.
The testimony tends to establish the following facts: Plaintiff at the time of the accident was twenty-two years of age, in good health, and residing on the west side of Grand avenue, in the City of Portland, and a little south of, and on the opposite side of the street from, Neustadter’s shirt factory, where she had been employed for about two years. On the morning of July 12, 1906, while crossing the avenue from her home to the factory, a trolley wire of the company, which had for some time been sagging, fell, striking plaintiff on the forehead, and, glancing down her face, struck her two or three times, the effect of which was to daze and cause her to stagger, and to be unable .to hear one nearby who called to her. She remained in such condition for a few minutes, and the first incident of which she appears to have been cognizant was that her mother, who had met her at the sidewalk, was caring for her at their home, when she discovered that one side of her head and body was numb and without feeling. After remaining at home about 30 minutes, she returned to her work, but, finding herself unable to resume work, on request of her employer, returned home, and, owing to her nervous and impaired physical *501condition, did not renew her occupation at the factory until in September following. Soon after returning from the factory, a physician was called, who administered treatment, but her impaired physical condition failed to respond thereto for at least three or four days, when she began to improve, but her sense of taste and smell remained materially affected for some weeks thereafter. Plaintiff continued at home in poor health for two or three weeks, after which she went to Seaside, where she remained about one month, during which time she suffered, more or less, among other ailments, with pains in one side, arm, and back, which continued, and from which condition she had not fully recovered at the time of the trial. The plaintiff had prior to the accident often passed back and forth across the avenue at and near the point of the mishap, and for a period of at least ten days had noticed the trolley wire out of place and sagging but that it was not low enough for any one in crossing to come in contact therewith. She knew the wire carried a strong current of electricity, a contact with which would be very dangerous. The avenue at the place of the accident was paved with wooden boards between and on each side of the rails. The casualty occurred on an exceedingly hot day, without rain having fallen in the vicinity for some time previous thereto. It was the custom of the city to sprinkle the avenue at and near this place daily. The wire causing the injury had been used in the propelling of street cars by defendant, and a car had passed under the wire immediately before its breakage, and plaintiff at the time of receiving the shock was on a regular crosswalk, and between the rails on the east track of the company’s line.
1. The first error assigned demanding consideration relates to the action of the trial court in overruling defendant’s motion for nonsuit, and in refusing to direct *502a verdict in its favor. It has become a well-settled rule in this State that, although plaintiff at the time of resting may have failed to offer proof sufficient to entitle the cause to be submitted to the jury, a ruling which denies such motion will not be disturbed if the omission is thereafter supplied: Trickey v. Clark, 50 Or. 516, 519 (93 Pac. 457).
2. In this connection defendant maintains that, without the testimony introduced by plaintiff in rebuttal, the showing presented was inadequate to sustain a judgment, and that by reason thereof defendant was entitled to a directed verdict, and that the court accordingly erred in permitting the introduction of evidence, on rebuttal, of plaintiff’s shoe, as well as in error in admitting any of the testimony adduced in reference thereto. The shoe apparently was offered, not only on account of its slightly burned appearance, but for the purpose of disclosing the nails therein, which the evidence discloses may have served as a conductor of an electrical current through their contact with the nails in the boards between the rails where plaintiff stood at the time of receiving the shock.
3. This testimony, properly speaking, was a part of plaintiff’s case in chief, but the time and manner of its admission was a matter within the sound discretion of the court (Wigmore, Ev. §§ 1867, 1873), which discretion, we think, was not improperly exercised.
4. It can make no difference under the showing made where plaintiff was standing at the time of the accident, nor that dry boards are nonconductors of electricity, for circumstances are disclosed whereby the shock may have been received regardless of this feature. Much evidence was introduced by defendant in support of its theory that plaintiff could not have received a shock, if, at the time of the accident, she was upon the planks between the rails; but, whatever may be the *503opinion of defendant’s expert witnesses upon this subject, the fact remains that plaintiff was, in fact, struck by the wire, and did receive an electrical shock, from which substantial injuries resulted. True, there is room for a difference of opinion upon the question, but this was a matter for the jury, the findings of which are not subject to review here. It was also disclosed, if not conceded, that, if the boards were damp, they were conductors of electricity, and the shock could have been received in that manner. Hence, while it was established that the day was very dry and warm, this feature is met by the testimony to the effect that the street was usually sprinkled, and in that locality ‘'always looked damp in the morning,” to say nothing of the testimony respecting the shoe introduced in evidence and the effect it may have had on the occasion.
5. Nor is the defense that plaintiff was negligent in crossing the street, with full knowledge of the sagging wire, sufficient, under the record, to preclude a recovery. That this avenue or street is a public thoroughfare, and that the wire had been left in a sagging condition for more than ten days, was unquestioned. In fact, it was, and is, admitted by defendant. Under the circumstances here revealed, it would be unreasonable to hold it necessary for people desiring to cross a street to abandon one crosswalk for another located at some other and more inconvenient point. The public has at all times a right to the use of its highways, and it was incumbent upon defendant to keep its wires along such public thoroughfare in a reasonably safe condition, and it is conceded this was not done.
6. Had the wire been lying in the street, or sufficiently near the ground to be dangerous, and plaintiff, with full knowledge thereof, consciously walked into it, a different question would be presented, and defendant’s contention in reference thereto might under such *504circumstances be tenable: Carroll v. Grande Ronde Elec. Co. 52 Or. 370 (97 Pac. 552). But, regardless of what might be the legal effect under such circumstances, it appears in this instance that the wires, although sagging, were not hanging low enough to be dangerous to persons crossing, and their continued use in propelling cars was sufficient indication of their security to lead a reasonably prudent person to rely on their safety. Considering the entire record, ample testimony was adduced to justify a submission of the cause to the jury, from which it follows that the motion to direct a verdict in defendant’s favor was properly denied.
7. The next question requiring attention relates to the admission of expert testimony. Lay witnesses were called, and testified to the effect that they were intimately acquainted with plaintiff prior to the accident, saw her frequently and observed her condition immedaitely after, and for some time subsequent to, the accident, and that her health and general physical condition since receiving the shock, as compared with her former appearance, had materially changed, indicating her health to have become impaired. It is contended that this line of inquiry should have been excluded on the ground that the facts testified to were within the exclusive province of the jury, and not proper subjects for opinion evidence of laymen. Our attention is directed to Burton v. Severance, 22 Or. 91 (29 Pac. 200), and Chan Sing v. Portland, 37 Or. 68 (60 Pac. 718), in support of this position. The effect of these cases, however, was merely to hold that witnesses should not be permitted to give their views concerning any of the matters in issue, nor to give opinions on questions which do not call for expert testimony, for the reason that such matters are within the exclusive providence of the jury. But the testimony given in the case under consideration relative to the general appearance and state of plaintiff’s *505health after the accident, as compared to her usual physical condition prior thereto, are facts which the average layman is competent to observe, and which the jury is entitled to consider in determining whether the accident occasioned the alleged injury. If, for example, A loses an arm in an accident, the loss of which becomes a subject of inquiry in an action for damages, and a lay witness is called, who testifies that he knew plaintiff in such a case before the accident, saw him frequently and noticed nothing unusual in his appearance, but that he met him shortly afterwards, when he observed that he had but one arm and appeared to be suffering from the wound caused by the loss, it could not well be said that this was an invasion of the province of the jury; for the facts elicited by these statements would tend to disclose, when coupled with other incidents and facts presented, a basis from which the jury could infer that the accident complained of was the proximate cause of the loss of the limb.
8. Nor would such evidence be subject to the objection that the witness was not a physician or surgeon; for evidence of this class, like that under consideration, relates only to the comparative general appearance of the physical condition of the person respecting whom the testimony was given. In Bridge v. City of Oshkosh, 71 Wis. 363 (37 N. W. 409), questions similar in import to those here complained of were asked of lay witnesses, and were answered over the objections of the defendant, the admission of which was assigned as error, in reference to which the court on appeal observes: “Under well-established rules of law applicable to cases of this kind, where personal injuries to the plaintiff are the subject of inquiry and the basis for awarding damages, evidence of the kind ádmitted by the court in this case is clearly admissible. * * The propriety of permitting a witness who is not an expert, but who is acquainted *506with the injured person and has seen him frequently before and after the injury, to testify as to any changes either in his physical or mental condition, is established. * *” Also Wigmore, Ev. § 568; Robinson v. Exempt Fire Co. 103 Cal. 1, 5 (36 Pac. 955: 24 L. R. A. 715: 42 Am. Rep. 93); Parker v. Boston & Hingham S. Co. 109 Mass. 449, 451; Evans v. People, 12 Mich. 36; Isenhour v. State, 157 Ind. 517 (62 N. E. 40: 87 Am. St. Rep. 236).
9. It is next urged, in this connection, that the court erred in permitting Albert Meserve, a witness for plaintiff, to testify as an electrical expert as to the effect the wire striking the plaintiff might have upon her general physical condition, and as to what, in his opinion, was the cause of plaintiff’s suffering, as disclosed by a hypothetical question submitted to him. Before giving his views on the subject, the witness stated that he was a graduate of the electrical engineering department of the University of Oregon; that he had had six years’ practical experience as an electrician, four years of which was as a dynamo tender of the Portland General Electric Co., one year as a shop-man, and about one year as an electrical contractor; that he had received quite a number of shocks, had observed others, and was familiar with the effects produced by personal contact with live wires; and that at the place of proximity by the plaintiff with the trolley wire there was an electric current of between 500 and 550 volts. The witness was then asked to give some of the symptoms from which it might be inferred that a person had received an electrical shock, and over defendant’s objections, responded: “A shock of 500 volts directly through the body will invariably raise a blister or burn. As to the condition on the nerves, that depends upon the person. The personal equation would come in there, because a person who is not naturally *507nervous will not be particularly affected, so far as their nerves are concerned. My observation shows that, where one is very nervous, that their nervous system is quite heavily shocked. The length to which the shock will last depends upon the person and upon the amount of voltage. In this case, of course, if it would be 500, of course, you would only consider that.” He was then asked: “In what direction in the human body does electricity travel; along what avenues?” To this he replied, without objection, that he was not a medical expert, and could not say, but as a result of his studies in biology and physics would say that an electric current would, as a rule, take the path of the nerves as being the lines of least resistance, passing through the body in either direction, depending upon the direction in which the current was flowing. To this inquiry there was added: “Where is the very worst place, Mr. Meserve, that one can receive an electrical shock, being struck in what part of the body?” Objections to this question were interposed, like those of the preceding interrogatories, as to its relevancy, competency, and materiality, and that the proper foundation had not been laid therefor, which, being overruled, the witness answered: “Well, I should say that the heart was probably the worst part, because they would be apt to be killed.” A hypothetical question was thereafter asked the witness, narrating, in a brief manner, the circumstances leading up to the accident, including what purported to have occurred, together with a reference to plaintiff’s condition thereafter, concerning which the witness was requested to state what, under such circumstances, he would say the person was suffering from, to which, over defendant’s objection, he answered: “I would say she might be suffering from an electrical shock, so far as I have observed.” Defendant maintains that the witness was not shown qualified to testify *508relative to the effect the falling of a live wire might have upon the body of a person under.the circumstances narrated to him, in support of which defendant’s counsel direct our attention to State v. Anderson, 10 Or. 448; State v. Abrams, 11 Or. 169 (8 Pac. 327); Oregon Pot. Co. v. Kern, 30 Or. 328 (47 Pac. 917); Townley v. Oregon R. Co. 33 Or. 323 (54 Pac. 150); State v. Simonis, 39 Or. 111 (65 Pac. 595); Scott v. Astoria R. Co. 43 Or. 26 (72 Pac. 594: 62 L. R. A. 543: 99 Am. St. Rep. 710). These cases hold that opinions, to be entitled to consideration by the jury, must be based upon facts appearing in the record, supplemented by a manifestation of ample knowledge on the part of the witness of the subject under consideration, to justify an expression of his opinion, and that hypothetical questions must include only such facts as are fairly deducible from the testimony presented. While the form of the hypothetical question propounded to Meserve does not come strictly within the rules announced in the cases mentioned, it does not follow that defendant was in any manner prejudiced thereby, especially since the omitted facts, if any, were clearly brought out during the course of his subsequent direct and cross examination.
10. Again, it is not required that an expert witness on all questions bearing upon the health and physical condition of a person shall be duly licensed to practice medicine.
11. As stated by Mr. Wigmore, in his work on Evidence (section 556), the special and peculiar experience necessary for a witness to give testimony as an expert “may have been attained, so far as legal rules go, in any way whatever. All the law requires is that it should have been attained.” This testimony, says this eminent author, is usually, though not necessarily, found separately, and may be grouped into two classes:’“There *509is, first, the so-called ‘practical’ experience — the kind which is obtained casually and incidentally, yet steadily and adequately, in the course of some occupation or livelihood. From the advertising agent to the wood-chopper there is a long list of occupations in any one of which, and perhaps in that alone, the fitness will be obtained to acquire knowledge on a particular topic. There is, secondly, a systematic training, directed deliberately to the acquisition of fitness, and involving the study of a body of knowledge forming a branch of some science or art. This may be termed ‘scientific’ experience. Now the line, if any can be drawn, between these two, has no general legal significance. * * The question in each instance is whether the particular witness is fitted as to the matter in hand.” In the case before us the witness discloses that he is familiar with the subject under discussion, and the court in admitting his testimony holds him to be prima facie an expert for the purposes of the inquiry, and the showing made respecting his qualifications we 'think fully justified the course pursued.
12. It is for the court to determine in the first instance whether a witness offered as an expert possesses the proper qualifications, leaving the weight of the testimony of such witness, if admitted, to the jury: 5 Enc. Ev. 533; Thompson v. Ish, 99 Mo. 160 (12 S. W. 510: 17 Am. Rep. 552, 562).
13. In State v. Megorden, 49 Or. 267 (88 Pac. 306), a physician was called.to testify as an expert, and was asked what the effect of a blow on a person’s head, describing it as detailed by the two preceding witnesses, would have as to dazing and confusing the person receiving it, and answered that it would affect his reasoning faculties for a few moments. When questioned concerning his qualifications, and before responding to the interrogatories mentioned, the witness stated that *510lie had neither seen nor had a case where a person was struck in the manner and place as detailed to him. Notwithstanding an objection was made to the inquiries on the grounds that the witness was not shown to be qualified as an expert along this line, the testimony was held admissible on the theory that, while the want of experience or knowledge of the particular facts therein questioned might lessen the weight to be given to his testimony, it would not affect the competency of a witness otherwise qualified. In State v. Remington, 50 Or. 99 (91 Pac. 473), a practicing physician, after having qualified as such, and after having given evidence of a medical nature, was asked if he had ever handled firearms, and, after having answered in the affirmative, and to the effect that he had handled a 30-30 rifle, knew the size cartridge it required, and how large a hole a slug fired from it would make, was permitted, over timely objections, to narrate to the jury the size of the aperture it would make in a picket of a fence, through which the ball from the rifle under consideration had been fired, the admission of which was assigned as error, but, on appeal, was held admissible. In view of the fact that testimony of the class mentioned is deemed admissible, and especially since a physician is held competent (after disclosing knowledge on the special subject) to testify as an expert in handling and effect, etc., of firearms, there can certainly be no valid objection to an electrician testifying what effect an electrical charge of between 500 and 550 volts, when considered in connection with other facts detailed in the hypothetical question asked Meserve, may.have upon a person coming in proximity with the wire conducting it. Again, if, as in the Megorden case, a physician, after admitting his inexperience with patients receiving blows on the head similar to the one there considered, may be permitted to testify as to what, in *511his opinion, would be the effect upon a person inflicted with such a blow, there was certainly no error com-' mitted in permitting Dr. Courtney, who waited upon and treated the plaintiff, to explain her physical condition, sickness, time of recovery, and the probable effect the accident had upon her general health.
14. In this connection, it is further argued that the hypothetical question propounded to Meserve was insufficient, and should have been excluded for the reason that every detail of the facts connected with the accident was not included, in support of which we are cited to Maynard v. Oregon R. Co. 43 Or. 63, 74 (72 Pac. 590). In that case, however, the hypothesis was based upon an assumed injury, which was not shown to exist, for which reason the evidence sought by it was inadmissible, while in the case under consideration testimony was given tending to support all the facts alluded to in the hypothetical question, and which were ample to give the witness a clear knowledge of plaintiff’s -physical condition at the time of the accident, together with an adequate statement of the manner,, time when, and place in which the accident occurred, with all that followed, including plaintiff’s subsequent physical condition, experience, and treatment administered. True, everything which transpired may not have been included in the narrative, but we do not deem a reference to each and every detail essential. Only such facts are required as are requisite to the forming of an intelligent opinion on the subject considered: Wigmore, Ev. § 682; Pendleton v. Saunders, 19 Or. 9, 25 (24 Pac. 506).
15. But it is argued that because the hypothesis assumed that plaintiff, at the time of receiving the shock, was “on the car track,” such assumption is inconsistent with the- evidence, in that plaintiff, when struck by the wire, was between, and not on,- the rails. We think, however, in the light of the answers given by *512Meserve, when considered as a whole, the expression “on .the track,” whatever its technical meaning may be, did not in any way mislead the witness.
16. Moreover, the “car track” as here used clearly has reference to the space necessarily covered by defendant’s cars in passing: Potter v. Leviton, 199 Ill. 93 (64 N. E. 1029); Delaware Can. Co. v. Whitehall, 90 N. Y. 21.
17. It is next maintained that the court erred in instructing the jury, in substance, that after it was shown that the accident was caused by the breaking or sagging of the wire, which was the property of the defendant, it in law raised a presumption of negligence on its part, and that, unless it appeared there was contributory negligence on the part of the plaintiff sufficient. to make her acts the proximate cause thereof, the burden of proof was shifted to defendant to establish, by a preponderance of the evidence, that it was not at fault, and that the accident happened without any negligence or want of care on its part. The point here presented was urged, but decided adversely to appellant’s contention, in Boyd v. Portland Elec. Ry. Co. 41 Or. 336 (68 Pac. 810). In that case, under a similar state of facts, an instruction of like import was given by the trial court and upheld on appeal.
Some authorities from other jurisdictions are cited by counsel for defendant, which appear to sustain their contention on this point, but we are satisfied with the rule on the subject in forcé in this State.
The judgment is affirmed. Affirmed.
