delivered the opinion of the court.
From a judgment in pursuance of a verdict convicting Mm of the murder of W. R. Prewitt, and *26sentencing Mm to the penitentiary for life, the appellant, a lad of nineteen years, has appealed to this court, and complains, first, that the instructions given by the trial court, and particularly the one numbered the sixth, were prejudicial to him, and second, that an instruction on the law of voluntary manslaughter was refused him.
Other alleged errors do not appear to be substantial, and need not be noticed. The first instruction presents the law of murder in unobjectionable form; the second the law of involuntary manslaughter. The blow was inflicted with a wooden club — the half of a keg stave — • and if by its use the accused did not intend to produce death, he was to be found guilty of a misdemeanor oMy. The third instruction is on a point not involved here. The fourth and fifth were on the subject of insanity, though there was no testimony tending to .show such a mental condition, save an affidavit of the .accused for a continuance stating that his mother would prove him feeble-minded. Tkis~issue appears to have been an insignificant one. The sixth and objectionable instruction is as follows : “The law presumes that a sane man intends the natural and probable consequences of any act which he willfully and deliberately does.” There being no appreciable proof to the contrary, the accused must be held to be sane. The consequences of his willful and deliberate act was death. These consequences were easily assumed as naturally following the blow. Hence, the instruction is to the effect that the accused is presumed to have intended to kill the deceased by the use of the club.
• Mr. Wharton says: “The doctrine that malice and *27intent are presumptions of law to be inferred from the mere act of killing belongs, even if correct, to purely speculative jurisprudence, and cannot be applied to any case that can possibly arise before the courts.” •
In Madden v. State, 1 Kansas, 356, quoted and approved in Farris v. Commonwealth, 14 Bush, 373, it is held that the presumption that the accused intends the natural and probable consequences of his own acts is not one of law to be applied by the court, but of fact to be weighed by the jury. (See also Payne v. Commonwealth, 1 Met., 375; Coffee v. The State, 3 Yerg., 283 ; Maher v. People, 10 Mich., 212.)
The only plea available to the accused under the instructions to save himself from conviction for murder was that it was not his intention in using the club to produce death, and this plea he tried to make good by showing the facts and circumstances attending the assault.
He showed that he had been a- constant visitor at Prewitt’s house for some time — was visiting his daughter, and while the old gentleman had spoken sharply to him the night before, he had felt only aggrieved or hurt and not angered; that he sauntered- into the shop of the deceased the next morning, thinking or hoping that he would be received with a friendly nod or word, and the way thus paved for a continuation of his visits. After waiting from ten to twenty minutes, he, the deceased not speaking to him, suddenly picked up a wooden stick, struck the old man and ran home, without conceiving that the lick could result seriously. He argues if he had intended to kill, he would have used some deadly weapon, or at any rate, some heavy *28iron bar or poker lying in tke blacksmith shop. But this defense, as we have seen, while nominally left open to the accused by the second instruction, was practically closed by the legal presumption defined in the sixth.
In the second place, we are convinced that the accused was entitled to have the jury instructed on the law of voluntary manslaughter. Whether or not malice, the very essence of murder, existed, was a fact to be determined by the jury, and all the attending circumstances of the homicide, including the mental condition of the accused, whether sober or drunk, whether feeble-minded or otherwise, whether provoked and incited into sudden passion at the moment of the assault with the stick, the character of the weapon used, all were matters legally put in proof for the consideration of the jury for the very purpose of guiding them to a correct conclusion on the degree of the appellant’s guilt. We do not review the facts in detail, as there is to be another trial.
For the reasons indicated, the judgment is reversed and a new trial directed upon the principles consistent with this opinion.
