delivered the opinion of the Court: ■
• 1. The first three assignments of error may be conveniently considered together. In the course of the examination of talesmen touching their qualifications as jurors, three challenges made by the Government for cause, were sustained by the court, and exceptions were taken by the accused.
(1) One of these, Morris Fitzgerald, stated that he had “ conscientious scruples against capital punishment.”
(2) Morris Blackman was examined at length, and having stated that he had a leaning towards the penalty of imprisonment for life, but could agree to capital punishment where there was no doubt, the court inclined to hold him competent. Upon further examination, however, it appeared, as stated by the court and agreed to by the juror, that in a case where the proof showed guilt beyond a reasonable doubt he would not convict of murder except upon condition'that the punishment should be imprisonment for *318life; but that he would convict of murder with the death penalty if there were no doubt at all.
(3) George H. Lee said that he had no conscientious scruples that would prevent him from finding an accused person guilty, but admitted that he had a bias in favor of imprisonment for life and a prejudice against the infliction of death as a punishment for murder, and would not agree to the latter, except in a very extreme case. The opinion expressed by the court in sustaining the challenge of the Government, was that a juror should “come to the question of punishment with an entirely unbiased mind; that the minds of the jury should not be biased upon the subject of punishment, but in such state as to be controlled entirely by the circumstances of the particular case.”
The contention of the appellant is that objections to jurors, as stated above, are no longer tenable because of the change in the statute punishing murder, which requires the. sentence to be imprisonment for life, instead of the death penalty, in case the jury shall, in their discretion, qualify their verdict of guilty by adding the words, “without capital punishment.” See act of January 15, 1897 (29 Stat. 487).
This statute commits to the sound discretion of an impartial jury the exercise of the power to compel the court to substitute imprisonment for life for the death penalty in the sentence for murder. The first question for decision is, guilty, or not guilty, as charged. If the verdict be guilty then the sentence of death will follow, unless the qualification authorized by the statute shall be added to that verdict.
The paramount interest of organized society in the preservation of peace and order would seem to require that the jury should, as far as practicable, be composed of men qualified to determine the first question fairly and without subjection to' the influence of a bias or prejudice in respect of the nature of the punishment to follow. See Logan v. *319United States, 144 U. S. 263, 291. We do not regard the question, however, as one that must necessarily be passed upon at this time. In the process of impaneling the jury, the talesmen are examined by and in the presence of the court touching their qualifications. Qualification is a question of mixed law and fact submitted to the sound discretion of the court, and the exercise of that discretion ought not to be disturbed, unless there be disclosed manifest error to the prejudice of the accused. Connors v. United States, 158 U. S. 408, 413; Garlitz v. State, 71 Md. 293, 301; Howgate v. United States, 7 App. D. C. 217, 236.
An accused person brought to trial acquires no vested right to have a particular member of the panel sit upon the trial of his case, until, at least, he shall have been accepted and sworn. What the accused is entitled to is a trial by an impartial jury duly qualified and impaneled to. sit thereon. That the appellant had such a jury is not denied. No objectionable person was forced upon him; his peremptory right of challenge was not exhausted. Assuming, however, that error may have been committed in excluding the three talesmen, what legitimate purpose would be subserved by reversing the judgment and remanding the case for trial before another impartial jury ? 1 Thompson on Trials, Sec. 120; Hayes v. Missouri, 120 U. S. 68, 71; Spies v. Illinois, 123 U. S. 131, 168.
2. The second assignment of error is on an exception taken to the action of the court in permitting John F. Kelley to be called as a witness by the prosecution. This witness was a lieutenant of the police, and was named in the list of witnesses served upon the prisoner as residing at 31 G street N. W., in the city of Washington. It appears that he had been upon the' police force as a lieutenant for more than thirty years, and for twenty-seven years had resided at the address above given; but that he had removed to another place in the city about ten days before the service of the list. When the witness was called, the defendant objected *320to his being allowed to testify because of this error in naming his abode. The objection is founded on section 1033, Revised Statutes, which provides, among other things, that in a capital case a list of the witnesses to be produced on the trial for proving the indictment, stating the place of abode of each witness, shall be delivered to the accused two entire days before his trial. This is a substantial re-enactment of the act of April 30, 1790 (1 Stat. 118).
This statute preserves an important right to the indicted party. Its purpose is to enable him to inquire into the testimony that he will be called on to meet, and to enable him to prepare for his defense. In its general purpose and effect as a. shield of defense, the statute is unquestionably mandatory upon the Government. Logan v. United States, 144 U. S. 263, 304. At the same time reasonable limitations upon its letter and operation have been recognized in that its benefits may be waived expressly, or impliedly by failure to make seasonable objection. Hickory v. United States, 151 U. S. 303, 308.
And again, whilst it would in general be the safer practice, where the statute is invoked, to postpone the trial for a time sufficient to give a new notice curing the defects of the original, we are of the opinion that there may be special circumstances so apparent and so plainly exceptional as to create a situation obviously beyond the limits of the contemplated purpose and operation of the statute. It is apparent from the record in this case that the failure to give the correct place of abode in the city, which the statute contemplates, was the result of a natural mistake.
In the second place, it is very clear that the appellant knew well who the witness was and how he might be found and was not in the slightest degree deceived by the error in the abode as given. The record shows, also, after settling the fact of the witness’ abode at a place different from, that stated in the notice, the following colloquy between the court and the counsel for the defendant: “The Court. Do you *321mean to state to the court that you have looked up the number that was given you as Lieutenant Kelly’s address and could not find him, and therefore you are surprised? Do I understand you to say that? Counsel. I do not care to make any statement on that point at all, unless you demand it of me. The Court. If you will make this statement it will have a very material effect upon the court’s decision. Counsel. Then I would like to be relieved from making any statement in that regard; when the time comes for proof we can dispose of it in that way. The Court. What proof? Counsel. Proving whether we did or did not make inquiry and what the result was. The Court. There must; be good faith exercised towards the court, and therefore if you say to the court that you consulted this number and could not ascertain who this witness was, and therefore it is a surprise to you when he comes on the stand, then the court’s ruling would be very different.”
We can not give our consent to a construction of the statute that would make it applicable to the facts and circumstances above stated and thereby necessitate the reversal of the judgment.
3. The third assignment of error is founded on exceptions taken to the latitude permitted to the prosecution in the examination of defendant’s witness, Dr. J. A. Stoutenberg.
The bill merely states that the witness testified on behalf of the defendant to the opinion that the defendant was insane. In his cross-examination the witness was asked if he had heard of Dr. John P. Gray, who had been for thirty years medical superintendent of the New York State Lunatic Asylum, and that he had testified on the trial of Guiteau. Having replied in the affirmative, he was further asked if Doctor Gray had there stated whether he believed in moral insanity.
Defendant objected on the ground that the witness had stated that he had not appeared as an expert in any meaning of the term. Several pages of the record present the *322statements of the respective counsel and the remarks of the court on the point, and from this it appears that in reply to the foregoing objection the counsel for the Government asserted that Doctor Stoptenberg had been interrogated concerning his experience in the treatment of insanity and his having given testimony in many cases of inquiry into the mental condition of persons confined in the asylum of which the witness’ father is intendant; the purpose having been to show that witness had some technical knowledge of the subject. It was also stated that witness had spoken of the existence of moral insanity. Defendant’s counsel then stated that he objected to putting to this witness a question that was asked Doctor Gray in the Guiteau case. The court then ruled that the question might be stated, and counsel read from a report of the trial aforesaid a statement of Doctor Gray upon the subject of moral insanity. The court then held the question as asked objectionable because it assumed that Doctor Gray did actually testify to that effect.
In the course of further argument counsel for the defendant objected that the object “was to get Doctor Gray’s evidence in the case by . assuming that he said something at some time under such and such circumstances, when we do not know what the circumstances were, thus assuming that he said something there is no proof of.” Counsel for the Government then stated that he would read Doctor Gray’s statement defining moral insanity to the witness and inquire if he agreed therewith. The'court then, after further remarks by counsel, stated: “ I do not care anything about the volume.or what has been read. What I am deciding -upon is the definition of moral insanity; whether the witness agrees with that definition.”
The following question was then asked the witness;
“Q,. It is said that Doctor Gray, in explaining what the term moral insanity signified, used this language: ‘It is intended to signify a condition of perversion of the moral faculties or moral character of the individual, leaving the *323intellectual faculties still sound. Inasmuch as I in my own view can not conceive of any moral act or the exercise of any moral affection without an intellectual operation or mental action accompany it, so I can not possibly dissever this mental unity. I look upon man in his mental-condition as being a simple unit; that his mental being consists of his intellectual and moral faculties so united that everything he does must spring out of them jointly. Disease is a thing of the body; a sickness of the brain, if it is insanity. No physicial sickness could reflect itself through a man’s moral nature only.’ Do you agree with Doctor Gray in his definition?”
"Witness replied: “ I can not say that I agree with Doctor Gray.”
We can not agree with counsel that Doctor Stoutenberg does not occupy the attitude of an expert. He was a physician, had some experience with lunatics in the asylum of which his father was infendant, and had testified in cases of inquiry into their mental conditions.
It does not appear what his acquirements and experience ■actually were, nor is their extent of any importance. He expressed opinions that extended into the field of expert testimony, and his modest disclaimer can not avail against that fact.
It must be remembered that the statement referred to occurred in the course of argument before the court and was not a part of the evidence as submitted to the jury, though occurring in their presence. It could have been conducted away from them had counsel so requested. In the light, then, of what was said by the court and the manner in which it actually went to the jury, we can not agree that the purported statement of Doctor Gray as read or repeated was offered or understood to be offered as evidence to contradict Doctor Stoutenberg. The question was propounded to the witness in his cross-examination for the purpose of testing his knowledge of the subject of insanity, and *324it was immaterial whether it was read or stated by counsel. Considerable latitude of cross-examination is often important to the discovery of the truth under such circumstances; and its range is within the sound discretion of the court, the exercise of which will not be reviewed save in case of abuse. Davis v. United States, 165 U. S. 373, 176, 377; Conn., etc., Ins. Co. v. Ellis, 89 Ill. 516, 519. See, also, Davis v. Coblens, 12 App. D. C. 51, 53: S. C., 174 U. S: 719, 726; 8 Encyc. Pl. and Pr. 767.
The bill of exceptions is faulty in that it does not present concisely and distinctly the very point as decided by the court. Ascertaining it as correctly as we have been able to do from the stenographic report of the contentions and assertions of counsel, respectively, together with the statements of the court, which are contained in more than four pages of the printed record, we have discovered no abuse of discretion that can be treated as reversible error.
4. The exclusion of the evidence of John Hancock, a witness for the defendant, is made another ground of error. The witness was a nephew of the defendant and confessedly not an expert. He was offered to prove that he did not consider the prisoner in his right mind, and also that he had years ago received a severe blow on the back of the head which had rendered him unconscious for some hours. 'No facts or circumstances were stated or offered to be proved by the witness upon which his opinion in respect of the prisoner’s mental condition had been founded, and the court upon objection excluded the opinion, but let the fact of the receipt of the blow stand..
In this there was no error. Taylor v. United States, 7 App. D. C. 27, 36; 12 Encyc. L. 489 (2d Ed.).
5. The next assignment of error is upon an exception taken to a hypothetical question submitted to Dr. John B. Chapin, an expert witness called on behalf of the Government.
The statement submitted to the expert witness, upon *325which he was asked to express an opinion as regards the insanity of the defendant, presented substantially the facts descriptive of the homicide and the conduct and declarations of the defendant immediately thereafter that had been offered in evidence by the Government — facts, too, about which, it may be added, there was no dispute. Objection was made because the question did not cover all of the facts, or the assumed facts of the case. Counsel was then asked by the court to add what had been omitted. After some further colloquy, defendant’s counsel made a statement of some additional facts concerning defendant’s conduct after he had been taken to the Emergency Hospital, under a mistaken apprehension that he had taken poison, and some of his actions and statements after removal from there to the police station, and suggested that there were some other facts which he did not specify. He was .then requested to frame a question, which he declined to do.
The court then ruled as follows: “The question embraces the substantial facts as offered by the Government, and if there are any facts that the defendant thinks are material and might affect the witness’ opinion, that is a matter which he can test on cross-examination. As I understand the hypothetical questions, they must embrace the general statement as proven on the part of the Government. I think the question is sufficient, and the objection is overruled.” The witness then expressed the opinion that the defendant was sane. He was not cross-examined by the defendant.
Questions of this nature must be fairly framed with reference to the facts that have been offered and relied on in the evidence, and the hypothesis must be clearly and distinctly presented, so that there may be no misunderstanding by the witness and no confusion of the minds of the jury. Beyond this it would seem impracticable to frame a general rule applicable alike t6 all cases.
Having in view the particular facts and circumstances of the case, it has often been held that “hypothetical questions *326to an expert witness may be framed either upon all the facts in the case, or upon any part of the facts assumed to be true which is sufficient in itself.” 8 Encyc. PL and Pr. 755, and cases cited; 1 Thompson, Trials, Sec. 610.
Again, in other cases, it ymuld be proper to require the question to embody substantially all of the facts of the entire case, having any relation to the subject matter. 8 Encyc. PL and Pr. 576.
One case might admit of, or even require, the separation of the facts in evidence, and assumed for the purpose to be true, into one or more groups for the purpose of an opinion by the expert; the opinions, when given, being for consideration or rejection by the jury as they may consider the assumed facts to be true or untrue.
In a well considered case in Indiana it was held that the question might be framed upon the hypothesis of the truth of all of the evidence, or upon a hypothesis specially framed upon certain facts assumed to be proved for the purpose of the inquiry. Goodwin v. State, 96 Ind. 555. And the same rule has been applied in New York. Cole v. Fall Brook Coal Co., 159 N. Y. 59, 68.
In Michigan it was held, for reasons cogently stated in the opinion, that a question embodying all of the facts in evidence in that case would be objectionable, because of their complicated character and the probable confusion that would ensue. People v. Brown, 53 Mich. 531, 534.
In a case in a Circuit Court of the United States the length of the hypothetical statements were urged as objections to their admissibility, but the objections were overruled. In affirming the judgment, the Supreme Court said: “The witnesses do not appear to have been confused by their length; they expressed no inability to fully comprehend them. Nor did the court, though complaining of their length, indicate that they were unintelligible to the jury, or tended in any way to turn their minds from the point in issue.” Forsyth v. Doolittle, 120 U. S. 73, 77.
*327The numerous decisions upon questions of this character demonstrate the propriety of leaving the scope and limitation of hypothetical questions, that must depend largely upon the special circumstances of each case, in a very great degree, to the discretion of the trial court.
This is the conclusion of the Supreme Court of the United States expressly stated in the decision last cited. 120 U. S. 78.
We see no evidence of an improper exercise of discretion in the action of the court upon which the error has been assigned.
6. In considering the assignments of error founded on the general charge of the court, we think it is neither necessary nor important to set out the portions of that charge that were excepted to.
It is sufficient to say: (1) As regards the defense of insanity, the court gave each of the special instructions prayed on behalf of the defendant; and there is nothing in the general charge in conflict therewith. In its definition of insanity as a defense against conviction of crime it follows the established authorities, and has application to the facts of the case. See Taylor v. United States, 7 App. D. C. 27, 43 ; Davis v. United States, 165 U. S. 373, 378.
(2) The charge is not subject to the assignment of error, that it did not submit to the jury the right to find the defendant not guilty upon the Government’s case, irrespective of the defense of insanity. The jury were plainly told that they could find the defendant not guilty, or not guilty by reason of insanity, or guilty of manslaughter.
That the right to make the first finding received nothing but bare mention is due to the facts showing the commission of the homicide and the character of the defense made. The bill of exception shows that no evidence was introduced in denial of the Government’s evidence as to the commission of the homicide, and recites that upon the close of the Government’s case the defendant’s counsel stated to the court *328that the defense was insanity and then proceeded to examine witnesses on that issue alone.
Moreover, the exception as taken does not show that the attention of the court was specially called to any omission of detail in that regard.
(3) In regard to the finding of manslaughter the jury were told: “ You could find him guilty of manslaughter— that is, it is in your power to so find him; but I scarcely think, looking at the law and evidence in this case, that there is any reason to suppose that you would find a verdict of guilty of manslaughter.” The error, if any, was in mentioning the offense of manslaughter at all. As was said in a case by the Supreme Court, where, as here, the defense was insanity: “ There was no testimony to reduce the offense, if any there was, to manslaughter. If the defendant was sane and responsible for his actions, there was nothing upon which any suggestion of any inferior degree of homicide could be made, and therefore the court was under no obligation (indeed it would simply have been-confusing the minds of the jury) to give any instruction upon a matter which was not really open for their consideration.” Davis v. United States, 165 U. S. 373, 378 ; Sparf v.United States, 156 U. S. 51, 103.
Had the evidence required a statement of the law of manslaughter to be given to the jury, then an expression of opinion as made would have been improper. As applied here, however, it was but telling the jury that the evidence in the case would not justify a verdict of guilty of manslaughter ; and this was the correct view of the entire testimony. The defendant was guilty of murder or nothing. See, also, Allen v. United States, 164 U. S. 492, 495, 496.
8. The last assignment of error is on the refusal of the court to give this instruction, requested by the defendant:
“ Each juror should decide for himself upon his oath as to what his verdict should be. No juror should yield his deliberate conscientious convictions as to what the verdict *329should be, either at the instance of a fellow juror or at the instance of a majority. Above all, no juror should yield his honest convictions for the sake of unanimity or to avert the disaster of a mistrial.”
This instruction does not correctly state the duty and obligations of a juryman, and was properly refused. Allen v. United States, 164 U. S. 492, 501.
Having not been able to find any reversible error in the proceedings in this case, the judgment appealed from will be affirmed. Affirmed.
