delivered the opinion of the court:
Plaintiff in error contends earnestly, and not without reason, that the evidence does not support the verdict by that degree of proof required in a criminal case. The evidence as to some of the material matters was conflicting, and it was the peculiar province of the jury to weigh it and to determine the credibility of the witnesses. As the credibility of two of the witnesses was improperly attacked by the State and substantial error was committed in other respects during the progress of the trial, we will not pass upon the question whether the evidence was sufficient to support the verdict. There being a conflict in the evidence *587as to the guilt of the plaintiff in error, in order to sustain the verdict it must appear that the record is free from material and substantial error.
It is not denied that the fight occurred or that the defendant Jacobs struck Winters over the head and body with a club. It is contended, however, both that Jacobs acted in self-defense and that the injuries inflicted by him did not cause the death of Winters. Whether the wounds which caused death were inflicted before the examinations of Winters by the Drs. Wall at the emergency hospital and by Dr. Carter at the Cook county hospital-, or whether the body upon which the coroner’s physician, Dr. Hunter, performed an autopsy was that of Winters, were questions of the highest importance in determining the guilt or innocence of the defendants, and they were entitled to have them fairly submitted to the jury.
Dr. Charles D. Wall, who examined Winters on the afternoon of March 16, the second time he was taken to the emergency hospital, was called as a witness by the State. His examination and observance of the man extended over a period of an hour or an hour and a half. He observed two scalp wounds on the upper parietal region of the head, which he re-dresséd. He observed no symptoms to1 indicate a fracture of the skull and is positive in his statement that there was no skull fracture. Not being able in the time at his command to malee a complete diagnosis he sent Winters to the Cook county hospital. Upon being recalled by the State this witness was interrogated .as to a letter which had been sent by some person or persons to his superior in the health department. The witness produced the letter and it was examined by the court, who refused the offer of the State to put the same in evidence. The assistant State’s attorney asked the witness a long series of questions as to the contents of the letter; whether it called his attention to his conduct of this case; whether he knew, at the time he was *588testifying previously, that his conduct had been officially criticised; whether he had- made any explanation in' response to this letter, and whether the letter had been turned over to him by his superior in the ordinary course of business. The court sustained objections to all these questions, but the action of the State’s attorney in thus attempting to cross-examine and discredit his own witness, when considered in connection with his cross-examination of the witness Dr. Clarence H. Wall, which we will note later, must have inevitably operated to the prejudice of the defendants. During the examination the. court required the witness to state, over the objection of the defendants, whether he had been reprimanded by his superior officer after the receipt of the letter. The State’s attorney also asked the witness the following question in reference to the letter: “As a matter of fact, this communication calls attention to your conduct of that case, doesn’t it, particularly?” To this question the defendants objected and the court sustained the objection, whereupon the assistant State’s attorney remarked, “Well, it does.” Upon motion of defendants this remark was stricken from the record. This statement, made by counsel with the letter before him, when taken in connection with the whole of this cross-examination of his own witness and the cross-examination of the defendants’ witness Dr. Clarence H. Wall in reference to the same letter, was improper, and the action of the court in striking it from the record did not cure the error.
Dr. Clarence H. Wall was the physician in charge of the emergency hospital at the time Winters was first brought there, immediately after his arrest. He was not called by the State but was produced as a witness by the defendants. After testifying to the facts as detailed in the statement of this case he was cross-examined by the State’s attorney in reference to this same letter, for the pretended purpose of showing his interest. The cross-examination was conducted, in the main, along the same lines as the *589examination of Dr. Charles D. Wall, and while objections to nearly all of the questions were sustained, the witness Avas required to testify, over objections, that the letter was sent to Dr. Evans with reference to the treatment of Winters by the witness and with reference to the fact that he did not discover any fracture. A number of the questions sought to elicit the fact that the witness had seen a letter criticising his actions in this matter, and he Avas asked whether he had told Dr. Carter about the predicament he was in on account of it. Finally the State’s attorney asked him, “Were you aware that you were criticised by the grand jury of Cook county for your examination of Winters?” and the court having overruled the objection of the defendants to the question, the witness answered, “Sure; I read the letter.”
While the letter is not before us and the name of the Avriter is not disclosed by the record, it is evident from the examination of these two witnesses in reference to it that it contained a criticism by the members of the grand jury of the examinations of Winters made by the Drs. Wall, and that the only purpose of the State in offering it in evidence was to get this criticism before the jury. The action of the court in excluding the letter is inconsistent with the ruling requiring the witness to give his opinion as to the effect of its contents. This attempt to discredit the testimony of the two witnesses was improper. The methods of impeachment axe well known and well defined, and the State’s attorney should have availed himself of them if there were grounds for impeachment, instead of attempting to discredit the witness by improper insinuation and imputation. In calling Dr. Charles D. Wall as a witness, the State, in effect, represented him to the jury as a credible person and one worthy of belief. So far as can be observed, he was a willing witness and answered every question fairly. The State had no right, under the circum*590stances, to attempt to cross-examine him, much less to attempt to impeach him.
That the testimony of these two witnesses was material and the question of their credibility of the highest importance can be readily seen. Dr. Clarence H. Wall testified that he made a minute examination of Winters immediately after his arrest; that he found no fracture of the skull, no abrasion on or injury to the nose, no discoloration about the eyes and no hemorrhage of the ears; that he did find two scalp wounds on the back part of the head, which he treated by shaving the hair from around them, putting two stitches or sutures in each wound and dressing them with collodion. Dr. Charles D. Wall testified that he found no evidence of skull fracture, no injury to the left temporal bone, no discoloration about the eyes and no abrasion on or injury to the nose, but that he did find the two scalp wounds on the back of the head, each containing two stitches, which he re-dressed. Dr. Hunter, the coroner’s physician, testified that upon the body upon which he performed an autopsy, and which was represented to him as being the body of Winters, he found an abrasion of the nose, a fracture of the nose between the eyes, various abrasions and contusions over the body and a fracture of the left temporal bone. In his opinion the fractures of the nose and left temporal bone caused death. Although Dr. Hunter made a thorough examination and preserved notes of each injury found, his notes did not disclose the existence of the scalp wounds described by the Drs. Wall, and he testified that he was certain there were no sutures or stitches in any wound on the head. When the body claimed to be that of Winters was exhumed during the progress of the trial, Dr. Hunter was present and again noted evidences of these injuries but he did not testify to having found these scalp wounds. The contention of the defendants on the trial was, on the one hand, that the body examined by Dr. Hunter was not that of Winters, and, on the other, if *591it was the body of Winters, that his death was caused by injuries other than those inflicted by the defendant Jacobs and from which he was suffering up until the time he was taken to the Cook county hospital. The facts within the knowledge of the Drs. Wall were material on both these points, and the defendants were entitled to have their testimony presented to the jury free from any improper imputation. The court erred in permitting the State to examine these witnesses in reference to this letter or its contents.
Dr. Hunter was called by the State and testified that as coroner’s physician he had, on March 18, made a postmortem examination of a body which had been represented to him to be that of Winters. He was positive in his statement that there were no scalp wounds on this body, and particularly none containing stitches or sutures. Later, Dr. Hunter was recalled by the State for further examination, and was asked whether, during the month of March, he had performed an autopsy “on any other man who had scalp wounds as you have stated in this case.” Counsel for the defendants objected to that part of the question which assumed that the doctor had testified this body had scalp wounds, on the ground that the doctor did not so testify, whereupon the following occurred:
The court: “Don’t you remember he put his hand right along here (indicating) to show where they were?
The witness: “I don’t recall, your honor.
The court: “Well, I recall.”
To these statements of the court the defendants objected and excepted. As we have above pointed out, the question whether these scalp wounds were present on the body examined by Dr. Hunter was. very material, and it was error for the court to state, in the presence of the jury, his recollection of what the witness had testified to in that regard, and" particularly -in view of the fact that the record discloses that the witness had testified directly to the contrary. While it is true the jury heard the testimony of *592Dr. Hunter and are presumed to remember it correctly, still, where there is a difference of opinion as to what has been testified to, the jury would undoubtedly attach great importance to the statement of the court thus emphatically made. The effect of this statement is virtually the same as an expression by the court of an opinion on the facts involved. Dr. Hunter was again recalled by the State after the body claimed to be that of Winters had been exhumed, and at the close of his testimony on this occasion the court made the following oral announcement to the jury:
“Gentlemen of the jury, I want to make a statement at this time. My attention was called to the fact by counsel for the defendants that I had made some statements of what Dr. Hunter had said in his testimony. You should ignore that entirely. That should be stricken from the record. You want to go entirely by your own recollection of what was said, and not by what the court may inadvertently say about what any witness has testified.”
This statement did not cure the error. Even if the error could be remedied in this manner, it will be observed that the court failed to state that he was mistaken as to the scope of Dr. Hunter’s testimony, and while'the jury are told to disregard the statement, they are left to infer that the court still believed that the testimony of the doctor was as he had stated it. The statement of the court made during the examination of Dr. Hunter was wholly unnecessary in ruling on the objection, and we think it was most damaging to the defendants.
Plaintiff in error complains of the eighth instruction given on behalf of the State. The instruction is as follows:
“The court instructs the jury further, as a matter of law, that the law presumes that a person intends all the natural, probable and usual consequences of his acts; that when one person violently assails andther, not in self-defense, and not in a sudden heat of passion which is caused by a provocation apparently sufficient to make the passion *593irresistible or involuntary, and not to prevent the commission of a known felony upon either the person or property of such assailant or another, and not to prevent entry into the habitation of another by one who manifestly intends to enter the same for the purpose of violently assaulting or offering personal violence to some person dwelling or being therein, and the life of the party thus assailed is actually destroyed in consequence, then the legal and natural presumption is that death or great bodily harm was intended, in which case the law implies malice, and such killing would be murder.”
In this case, self-defense was relied on as one of the defenses, and it is contended that in such a case, and in a case where it is a controverted fact as to whether or not the life of the party injured is destroyed in consequence of the injury, it is error to give this instruction, for the reason that it assumes both that the deceased was assailed not in self-defense, and that his life was actually destroyed in consequence of the assault. If the jury had been told in express terms that defendants did not act in self-defense and that Winters died as a result of the injuries inflicted by the defendants it would have been error. We believe this instruction may have been-so understood by the jury, and for that reason should have been refused.
The refusal of the court to give to the jury defendants’ instruction No. 2 is complained of. This instruction is, in substance, the same as defendants’ instruction 25 given, and it was not error to refuse it.
For the errors indicated the judgment of the criminal court is reversed and the cause remanded for a new trial.
Reversed and remanded.
