On October 28, 1913, at the crossing of West Locust and Seventh Streets in the city of Des Moines, the plaintiff was struck and injured by an automobile moving west on Locust, driven by the defendant, Henry G-. Baker. The petition alleges that such injury was occasioned without fault on the plaintiff’s part by the negligence of both Henry G-. Baker and his codefendant, William H. Baker, and that the injuries received by her were many and serious. The petition particularizes the acts and omissions constituting the alleged negligence, as being the failure on defendants’ part to have chains upon the wheels of their automobile, although the street was icy and slippery; and the driving and operation of the car at a reckless or careless rate of speed. Further negligence is charged in the failure of the defendants
“You are instructed that the burden of proof is upon the plaintiff to show,- by a preponderance of the evidence, that, at the time in question, the defendant ITenry G. Baker was driving said car for and on behalf of the defendant Wm. Henry Baker. You are further instructed that, if the defendant Henry G. Baker at. said time was driving said car for the purposes and benefit of the defendant Wm. Henry Baker, then and in that event, he would be the servant, agent, or representative of the defendant Wm. Henry Baker. If you fail to find that said Henry G. Baker was acting as the servant, agent or representative of the defendant Wm. Henry Baker, in driving said car at said time, then you will return yoúr verdict for the defendant Wm. Henry Baker. If you find that said Henry G. Baker was acting at said time as the servant, agent or representative of the defendant Wm. Henry Baker, then, in that event, the said Wm. Henry Baker would be responsible for the negligent acts, if any, of said Henry G.*1069 Baker, and the instructions following would apply to both defendants.”
Assuming, though not deciding, that the quoted instruction would be correct in a case calling for the submission of such question to the jury, there was no fact or circumstance in evidence from which the jury could be permitted to find the existence between the defendants of the relation of master and servant, or of principal and agent; and, by the refusal to direct a verdict for the father and by the giving of the quoted instruction, the jury were turned loose to hunt for a verdict in the wide field of conjecture. The motion for a directed verdict in favor of this defendant should have been sustained.
Concerning the effect of this ordinance, the court instructed the jury as follows:
“You are further instructed that, by an ordinance of the city of Des Moines, Iowa, pedestrians are given the right of way over crossings at street intersections; and you are instructed that, under said ordinance, the plaintiff had a right to cross over said crossing at Locust and Seventh Streets, if she was attempting to cross said intersection on the crossing, as defendants’ automobile approached the crossing; and it was the duty of the defendants to observe such right of way*1071 of plaintiff, and, upon approaching said crossing, to have such machine so under control as to grant such right of way, and a failure so to do would be negligence upon the part of the defendants. The defendants would have a right to pass behind the plaintiff after plaintiff hád gone beyond the line upon which the said automobile was proceeding, if you find she had passed beyond said line, but in so doing defendants must exercise ordinary care and prudence; and plaintiff would have a right to turn on said crossing and proceed the other way, but in so doing plaintiff must exercise ordinary care and caution, in which event it would be the duty of the defendants to drive such car and have it under such control as an ordinarily careful and prudent person would, under the circumstances, to avoid injuring the plaintiff, and a failure to so pass and drive, and have said automobile under control, would constitute negligence.”
“I met the plaintiff day before yesterday, and made an examination of her touching her nervous system. From my observation, I believe she is suffering with nervous prostration.”
With this conclusion as a foundation, counsel then framed hypothetical questions embodying plaintiff’s version of the facts as to her prior state of health, the alleged circumstances of her injury and of her condition since that time, and asked as to the effects of such experience upon the nervous system of the sufferer. He then continued with the following question:
“Q. Taking into consideration the hypothetical question put to you respecting the person, and then taking into consideration the further fact that the person attempted to be described in the hypothetical question is the plaintiff, whom you have recently examined, and found her nervous system in the condition that you have described it to be in, assuming that she had passed through the experience detailed in the question, you may tell the court and jury whether, in your opinion, her nervous system, because of these matters referred .to, assuming them to be true, and tak*1074 ing into consideration her present condition, is or is not her nervous system permanently.impaired and injured?”
Objections to the interrogatory being overruled, the witness answered:
“I believe the nervous system of the witness will never be as strong and good in her life as it was before the injuries were received.”
On cross-examination, Dr. Iiill says he never examined the plaintiff except on the one occasion mentioned, and that he made no physical examination to verify the existence of physical pain and suffering. He adds:
‘ ‘ In determining Miss Switzer was suffering from nervous breakdown, I made my diagnosis and determined that question from the information I obtained from Dr. Lynch and Mrs. Hedges. I made a mental examination by asking a lot of questions with regard to health and habits and sleep, and with regard to what the plaintiff can do and what she formerly did and is unable to do now. Whether she could sleep or not, I determined from her statements. The same is true as to what she could and could not do. . I made out the diagnosis from what the plaintiff, Mrs. Hedges and Dr. Lynch told me. ’ ’
The objection made to this testimony is that the diagnosis stated by Dr. Hill is not competent evidence, because it is confessedly based upon hearsay, instead of facts coming under His own observation; and, as this diagnosis so derived was embodied in the hypothesis upon which the further opinion of the witness' is founded, the testimony or opinion elicited is not entitled to any consideration. The question thus presented "to the court is not, .as counsel for appellee seem to think, whether expressions of present pain and suffering on part of plaintiff were admissible in evidence. The competency of such evidence, as a rule, is too well settled ‘to permit of argument. Neither is it a question whether Dr. Hill, as an expert, could properly state his opinion based upon a personal examination of the plaintiff, or his opinion
“It was essential that the jury should be informed as to the facts upon which the expert based his conclusions in order to determine whether they were well founded. If the facts were not disclosed, Ms conclusions could not be controverted. Ye might have been deceived by a false statement prepared for the occasion, and for the purpose of making him a valuable witness upon the trial.”
As we have already noted, the record in this case contains no statement of the information received by the witness from Dr. Lynch or Mrs. Hedges, or indeed from the plaintiff herself, and shows that he was not prepared to express an opinion based upon his own knowledge of plaintiff’s condition. This is very clear from the admitted fact that he never treated plaintiff professionally, and that he made his diagnosis wholly upon statements made to him by the persons above named. In Weatherbee’s Exr. v. Weatherbee’s Heirs,
“A medical, witness must give the facts on wMch his opinion is founded, in connection with his opinion. If those facts necessarily include information given him by the attendants of the patient, his opinion is not competent, for those communications are hearsay.”
In Stevens v. People (Ill.),
“We know of no well-considered case where it is held competent for the physician to testify that he reached his conclusion or formed his opinion as to the ailment or physical condition of the patient from the cause or history of the injury, ailment or disease as narrated by the patient.”
Quite in point is the case of Vosburg v. Putney,
“He answered it ‘under the history he learned at the time.’ What facts about the case did he learn, and from whom did he learn them ! Were they true or false! He does not even give his opinion upon the testimony of other witnesses in court, and no hypothetical statement was submitted to him. No foundation recognized by any authority was laid for his answer to such a question, and he did not show himself competent to answer it.”
In the case before us, there was a hypothetical statement submitted to the witness; but, for reasons to which we shall later refer, wé think it was equally objectionable. -Says the Wisconsin court:
“The jury should in every case distinctly understand what 'are the exact facts upon which the expert bases his opinion.” Bennett v. State,14 N. W. 912 .
In Miller v. St. Paul City R. Co.,
“It is settled beyond controversy that a medical expert cannot be allowed to give his opinion on information which he has obtained out of court from third parties other than the patient.”
