In October, 1900, an information was filed by the district attorney, charging the defendant with the crime of “attempting to kill by means not constituting an assault. ’ ’
Again, in Burns v. Barenfield, 84 Ind. 43, a physician was permitted to give his opinion concerning the treatment of a patient, based upon his own examination, and it was held error, the court saying: “The opinion of an expert must be based upon proved or admitted facts, or upon such as are assumed for the purpose of a hypothetical question. The answer of the witness was not based upon facts stated by him. What he knew about the case might, and doubtless did, embrace much more than he had stated to the jury. How much or what he knew about the case was, in a great measure, unknown to the court and the jury. It is the clear right and duty of the jury to judge of the truth of the facts upon which the opinion of the expert is based. If his opinion is based upon what he may suppose he knows about the case, upon facts, it may be, altogether irrelevant, and unknown to the jury, it would be impossible for them to pass upon the truth of the facts upon which the opinion may be based, or to apply the opinion of the expert to the facts. Neither court nor jury can know the facts upon which the opinion rests. It is obvious that, where the expert delivers his opinion from what he supposes he knows about the case, he must assume and exercise both the functions of the court and the jury ; he determines that which he knows is both relevant and true. The relevancy of the facts must be determined by the court; their truth by the jury. The witness can not pass upon such questions.” This rule was not observed in the examination of Doctor Merracle, but he was asked to give his opinion, as a physician, as to what the general symptoms indicated.
