Christiancy, J.
The prisoner was charged with an assault with intent to kill and murder one Patrick Hunt. The evidence on the part of the prosecution was, that the prisoner entered the saloon of one Michael Foley, . . . where said Hunt was standing with several other persons; . . . that, on entering the saloon, he immediately passed nearly through it to where said Hunt was standing, and, on his way towards Hunt, said something, but it did not appear what, or to whom; that as soon as the prisoner came up to where Hunt was standing, he fired a pistol at Hunt, the charge of which took effect upon the head of Hunt, in and through the left ear, causing a severe wound thereon; by reason of which Hunt in a few moments fell to the floor, was partially deprived of his sense of hearing in that ear, and received a severe shock to his system which caused him to be confined to his bed for about a week, under the care of a physician; that immediately after the firing of the pistol prisoner left the saloon, nothing being said by Hunt or the prisoner. . . . The prisoner offered evidence tending to show an adulterous intercourse between his wife and Hunt on the morning of the assault, and within less than half an hour previous; that the prisoner saw them going into the woods together about half an hour before the assault; that on their coming out of the woods the prisoner followed them immediately . . .; that, on their coming out of the woods, the prisoner followed them and went after said Hunt into the saloon, where, on his arrival, the assault was committed; that the prisoner on his way to the saloon, a few minutes before entering it, was met by a friend who informed him that Hunt and the prisoner's wife had had sexual intercourse the day before in the woods. This evidence was rejected by the court, and the prisoner excepted. Was the evidence properly rejected? This is the main question in the case, and its decision must depend upon the question whether the proposed evidence would have tended to reduce the killing--had death ensued--from murder to manslaughter, or rather, to have given it the character of manslaughter instead of murder? If the homicide--in case death had ensued--would have been but manslaughter, then defendant could not be guilty of the assault with intent to murder, but only of a simple assault and battery. The question therefore involves essentially the same principles as where evidence is offered for a similar purpose in a prosecution for murder; except that, in some cases of murder, an actual intention to kill need not exist; but in a prosecution for an assault with intent to murder, the actual intention to kill must be found, and that under circumstances which would make the killing murder.

To give the homicide the legal character of murder, all the authorities agree that it must have been perpetrated with malice prepense or aforethought. This malice is just as essential an ingredient of the offense as the act which causes the death; without the concurrence of both, the crime can not exist; and, as every man is presumed innocent of the offense with which he is charged till he is proved to be guilty, this presumption must apply equally to both ingredients of the offense--to the malice as well as to the killing. . . . It is not necessary here to enumerate all the elements which enter into the legal definition of malice aforethought. It is sufficient to say that, within the principle of all the recognized definitions, the homicide must, in all ordinary cases, have been committed with some degree of coolness and deliberation, or, at least, under circumstances in which ordinary men, or the average of men recognized as peaceable citizens, would not be liable to have their reason clouded or obscured by passion; and the act must be prompted by, or the circumstances indicate that it sprung from, a wicked, depraved or malignant mind--a mind which, even in its habitual condition, and when excited by no provocation which would be liable to give undue control to passion in ordinary men, is cruel, wanton or malignant, reckless of human life, or regardless of social duty.
But if the act of killing, though intentional, be committed under the influence of passion or in heat of blood, produced by an adequate or reasonable provocation, and before a reasonable time has elapsed for the blood to cool and reason to resume its habitual control, and is the result of the temporary excitement, by which the control of reason was disturbed, rather than of any wickedness of heart or cruelty or recklessness of disposition; then the law, out of indulgence to the frailty of human nature, or rather, in recognition of the laws upon which human nature is constituted, very properly regards the offense as of a less heinous character than murder, and gives it the designation of manslaughter.
To what extent the passions must be aroused and the dominion of reason disturbed to reduce the offense from murder to manslaughter, the cases are by no means agreed; and any rule which should embrace all the cases that have been decided in reference to this point, would come very near obliterating, if it did not entirely obliterate, all distinction between murder and manslaughter in such cases. We must, therefore, endeavor to discover the principle upon which the question is to be determined. . . .
The principle involved in the question, and which I think clearly deducible from the majority of well considered cases, would seem to suggest as the true general rule, that reason should, at the time of the act, be disturbed or obscured by passion to an extent which might render ordinary men, of fair average disposition, liable to act rashly or without due deliberation or reflection, and from passion, rather than judgment.
To the question, what shall be considered in law a reasonable or adequate provocation for such state of mind, so as to give to a homicide, committed under its influence, the character of manslaughter? On principle, the answer, as a general rule, must be, anything the natural tendency of which would be to produce such a state of mind in ordinary men, and which the jury are satisfied did produce it in the case before them--not such a provocation as must, by the laws of the human mind, produce such an effect with the certainty that physical effects follow from physical causes; for then the individual could hardly be held morally accountable. Nor, on the other hand, must the provocation, in every case, be held sufficient or reasonable, because such a state of excitement has followed from it. . . .
In determining whether the provocation is sufficient or reasonable, ordinary human nature, or the average of men recognized as men of fair average mind and disposition, should be taken as the standard--unless, indeed, the person whose guilt is in question be shown to have some peculiar weakness of mind or infirmity of temper, not arising from wickedness of heart or cruelty of disposition.
It is, doubtless, in one sense, the province of the court to define what, in law, will constitute a reasonable or adequate provocation, but not, I think, in ordinary cases, to determine whether the provocation proved in the particular case is sufficient or reasonable. This is essentially a question of fact, and to be decided with reference to the peculiar facts of each particular case. As a general rule, the court, after informing the jury to what extent the passions must be aroused and reason obscured to render the homicide manslaughter, should inform them that the provocation must be one, the tendency of which would be to produce such a degree of excitement and disturbance in the minds of ordinary men; and if they should find such provocation from the facts proved, and should further find that it did produce that effect in the particular instance, and that the homicide was the result of such provocation, it would give it the character of manslaughter. Besides the consideration that the question is essentially one of fact, jurors, from the mode of their selection, coming from the various classes and occupations of society, and conversant with the practical affairs of life, are, in my opinion, much better qualified to judge of the sufficiency and tendency of a given provocation, and much more likely to fix, with some degree of accuracy, the standard of what constitutes the average of ordinary human nature, than the judge whose habits and course of life give him much less experience of the workings of passion in the actual conflicts of life.
The judge, it is true, must, to some extent, assume to decide upon the sufficiency of the alleged provocation, when the question arises upon the admission of testimony; and when it is so clear as to admit of no reasonable doubt upon any theory, that the alleged provocation could not have had any tendency to produce such state of mind, in ordinary men, he may properly exclude the evidence; but, if the alleged provocation be such as to admit of any reasonable doubt, whether it might not have had such tendency, it is much safer, I think, and more in accordance with principle, to let the evidence go to the jury under the proper instructions. As already intimated, the question of the reasonableness or adequacy of the provocation must depend upon the facts of each particular case. That can, with no propriety, be called a rule (or a question) of law which must vary with, and depend upon the almost infinite variety of facts presented by the various cases as they arise. . . .
The same principles which govern, as to the extent to which the passions must be excited and reason disturbed, apply with equal force to the time during which its continuance may be recognized as a ground for mitigating the homicide to the degree of manslaughter, or, in other words, to the question of cooling time. This, like the provocation itself, must depend upon the nature of man and the laws of the human mind, as well as upon the nature and circumstances of the provocation, the extent to which the passions have been aroused, and the fact, whether the injury inflicted by the provocation is more or less permanent or irreparable. . . . I am aware there are many cases in which it has been held a question of law; but I can see no principle on which such a rule can rest. . . .
It remains only to apply these principles to the present case. The proposed evidence, in connection with what had already been given, would have tended strongly to show the commission of adultery by Hunt with the prisoner's wife, within half an hour before the assault; that the prisoner saw them going to the woods together, under circumstances calculated strongly to impress upon his mind the belief of the adulterous purpose; that he followed after them to the woods; that Hunt and the prisoner's wife were, not long after, seen coming from the woods, and that the prisoner followed them, and went in hot pursuit after Hunt to the saloon, and was informed by a friend on the way that they had committed adultery the day before in the woods. I can not resist the conviction that this would have been sufficient evidence of provocation to go to the jury, and from which, when taken in connection with the excitement and "great perspiration" exhibited on entering the saloon, the hasty manner in which he approached and fired the pistol at Hunt, it would have been competent for the jury to find that the act was committed in consequence of the passion excited by the provocation, and in a state of mind which, within the principle already explained, would have given to the homicide, had death ensued, the character of manslaughter only. . . .

The judgment should be reversed and a new trial granted.
Manning, J. dissenting:
I differ from my brethren in this case. I think the evidence was properly excluded. To make that manslaughter which would otherwise be murder, the provocation--I am not speaking of its sufficiency, but of the provocation itself--must be given in the presence of the person committing the homicide. The cause of the provocation must occur in his presence. Justice Park, in Regina v. Fisher, . . . in speaking of the cause of provocation, says, "In all cases the party must see the act done." Any other rule in an offense so grave as taking the life of a fellow-being, in the heat of passion, I fear would be more humane to the perpetrator than wise in its effects on society. More especially since the abolition of the death penalty for murder, and the division of the crime into murder in the first and second degree. There is not now the same reason, namely, the severity of the punishment, for relaxing the rules of law in favor of a party committing homicide as before. It would, it seems to me, be extremely mischievous to let passion engendered by suspicion, or by something one has heard, enter into and determine the nature of a crime committed while under its influence. The innocent as well as the guilty, or those who had not as well as those who had given provocation, might be the sufferers. If it be said that in such cases the giving of the provocation must be proved or it would go for nothing; the answer is, that the law will not, and should not permit the lives of the innocent to be exposed with the guilty in this way, as it would do did it not require the cause of the provocation to occur in the presence of the person committing the homicide. . . .
