— The defendants were tried in the Randolph circuit court at Moberly in June, 1890, for the killing of John Emery. They were both found guilty of murder of the second degree, John McKinzie being-sentenced to the penitentiary for fifty-two years and Alexander McKinzie for ten, and the case is here on appeal. Defendants, through their counsel, contend that the court below erred in its instructions to the jury; in excluding competent and admitting incompetent evidence; in permitting the prosecuting attorney to cross-examine defendants as to matters not referred to by them in their examination in chief; in not granting a new trial on account of the separation of the jury; in not instructing the j ary in regard to manslaughter, and in not granting a new trial because the venue was not proved.
I. Defendant’s counsel contends that there was no evidence justifying the court in instructing the jurors -that they might find defendant, Alexander McKinzie, guilty of the crime of murder of the first or second degree, as an aider and abettor of John McKinzie in the commission of the homicide ; indeed, that all the evidence shows that he did not aid or abet John in the homicidal act. We do not think this contention sustained by the record. Thomas O’Brien testified that he saw the defendants and the deceased scuffling, and Mrs. Owens swore that the next morning after the homicide she heard Alexander McKinzie say that he and the deceased were contending about politics, and he had a cane in his hand and he tapped him with that and said: “I didn’t have a son that couldn’t lick him, even down to John.” We think the testimony of O’Brien and Mrs. Owens, taken in connection with the relationship existing between defendants and the conceded fact that Alexander was present, justified the *627court in leaving it to the jury to say by their verdict whether he aided and abetted J ohn in the homicide or not.
II. The court defined deliberation thus: Deliberation means in a cool state of the blood, and not in a heat of passion.” The contention is that this definition does not go far enough, and that it ought to have informed the jury what “a heat of passion” is. We think this point well taken. Deliberation, however, being an element of murder of the first degree only, and the defendants having been convicted of murder of the second degree this would not be reversible error, but, as the defendants can be tried again for murder of the first degree, it is important for us to notice it. The court ought to define that “heat of passion” produced by a just cause of provocation which will reduce the homicide to murder in the second degree, as also that “heat of passion” produced by a lawful provocation which will reduce it to manslaughter, as we hold that the court ought to instruct on these grades of the offense at the next trial.
III. The defendants’ counsel contends again that the court erred in its definition of murder of the second degree. The instructions in regard to this grade of homicide, given by the court, are as follows :
“2. If you believe and find from the evidence in this cause beyond a reasonable doubt, that the defendants at the county of Randolph, and in the state of Missouri, on or about the eighth day of September, 1889, wilfully, premeditatedly and with malice aforethought, but without deliberation, cut and stabbed with a knife, and that said knife was a deadly weapon, and, by cutting and stabbing, mortally wounded John Emery, and that said John Emery died at said Randolph county of said mortal wound within a year after said cutting and stabbing, then you should find defendants guilty of murder in the second degree ; and if you further believe and find from the evidence in this cause that defendants *628intentionally stabbed and mortally wounded deceased with a knife, and that said knife was a deadly weapon, then the law presumes that the killing was murder in the .second degree in absence of proof to the contrary, and it devolves upon defendants to adduce evidence to meet or repel that presumption on the part of the state.”
“5. The jury are instructed that from the simple act of killing with a deadly weapon the law presumes it to be murder in the second degree. If the defendants killed Emery by stabbing him with a knife then the law presumes the defendants guilty of murder in the second degree in the absence of proof to the contrary.”
We concede that apparently some expressions used in the earlier opinions of this court would seem to justify the giving of instruction, numbered 5. Judge Henry in the case of State v. Gassert, 65 Mo. 352, uses this emphatic language: “It has so often been decided by this court that, from the simple act of killing, the law presumes murder in the second degree, that it is no longer an open question in this state, whatever doubts may have been formerly expressed on the subject.” He then quotes several cases 'to sustain the doctrine announced; In the same case, however, he, speaking for himself alone, goes on to dissent from that view and then adds : “We think it equally well settled by the adjudged cases in this state that an intention to kill is one of the elements of murder in the second degree.” It must be observed that Judge Henry omits from the first proposition quoted both wilfulness and the use of a deadly weapon, and hénce we must infer from the whole opinion taken altogether, that he meant to announce the doctrine that from the simple act of an intentional killing with a deadly weapon the law presumed murder of the second degree. So we take it that even the earlier cases do not teach the doctrine contained in instruction, numbered 5. Be that as it may, however, *629we feel satisfied that all the cases, from the State v. Wieners, 66 Mo. 13, decided in 1877, to this time, hold that “from the simple act of killing with a deadly weapon” no presumption of law arises that the killing is murder of the second degree.
The court in this case told the jury in instruction, .numbered 2, that if defendants intentionally, premeditatedly and of their malice aforethought stabbed and killed deceased they were guilty of murder of the second degree, and then added in instruction, numbered 5, that, “from the simple act of killing with a deadly the weapon, the law presumes” it was done intentionally, premeditatedly and of malice aforethought, for that is what the instruction means if it means anything. The court told the jury explicitly that they must find defendants intentionally, premeditatedly and of.their malice aforethought stabbed and killed deceased in order to convict them of murder of the second degree and then told them that, from “the simple act of killing, the law presumed that 'it was murder of the second degree,” that is to say, if they found the defendants killed deceased with a deadly weapon they might presume, indeed the law required them to presume, that they stabbed and killed him intentionally and of their malice aforethought.
This the court should not have done. Both instructions, numbered 2 and 5, should not have been given. If they were intended to announce the same doctrine, then but one was necessary; if they were intended to announce distinct doctrines, then they tended to confuse and mislead the jury, and hence for that reason both should not have been given. Instructions that shade into and overlap each other are very objectionable and ought not to be tolerated. Instructions taken as a whole ought to.place .before the triers of the facts all the hypotheses of the case as presented by the evidence, but a single theory should not be repeated in *630two or more forms. Instructions that repeat the same theory in different language and phraseology do not instruct, but tend to confuse and mislead. We hold that instruction, numbered 2, declares the law correctly. It is almost a litei’al copy of the one given on the same subject, and received the sanction of this court, in State v. Elliott, 98 Mo. 158. This instruction with instruction, numbered 9, modified as required in this opinion, will present the issue as to murder of the second degree fairly before the jury.
As to the repetition of instructions on the same point we will state that in this case the court gave one instruction at the instance of the state, and eight at the instance of defendants, on the subject of the burden of proof, and reasonable doubt, each one couched in different language. These nine instructions must have produced in the minds of the jury a reasonable doubt as to what a reasonable doubt in legal contemplation is. The law as to the burden of proof and reasonable doubt ought to be couched in plain and concise language in a single instruction.
IV. Another contention of defendants is that the court ought not to have given instruction, numbered 9, at the instance of the state, which is as follows :
“9. The jury are instructed that the intent with which a person does an act is presumed to be that which naturally results from such act, and if you believe from the evidence that defendants stabbed John Emery at the time and place charged, with a knife, then the law presumes from the use of such knife that the defendants intended to kill said John Emery.”
The language of this instruction is too general. It cannot be said as a matter of law that a party intends to kill because he stabs another with a knife. If he intentionally stabs another in a vital part with a knife, and the knife is a deadly weapon, then the law is that he is presumed to have intended death. These elements ought to have been embodied in that instruction.
*631V. We find no evidence in the record before us justifying the giving of instruction, numbered 7, on the part of the state, which is as follows :
“7. If you believe and find from the evidence that defendant, Alexander MeKinzie, assaulted Emery with a cane for the purpose of punishing him for insulting words that Emery had used toward him, and at a time when he had no reasonable cause to apprehend immediate and impending danger of harm about to fall upon him from the hands of Emery, and that the defendant, John MeKinzie, took up the fight or assault, and stabbed and killed Emery, then the defendants were the aggressors and cannot justify the killing on the ground of self-defense.”
All the court was authorized to do in this case was to leave it to the jury to say whether Alexander aided and abetted John in the homicide and this should have been done in general terms. We fail to find any evidence in the record that Alexander ‘ ‘ assaulted Emery with a cane for the purpose of punishing him for insulting words Emery had used toward him, * * * and that John MeKinzie took up the fight,” and for that reason if no other this instruction should have been refused.
VI. Nor do we believe the evidence in the case authorized the court to instruct the jury that if defendants brought on the difficulty or voluntarily entered into it they could not invoke the right of self-defense, and hence instructions, numbered 6 and 8, ought not to have been given. Here again we find the same fault we referred to above, of dotoble instructions upon a single point, couched in different language. In this instance both ought t© have been refused.
VII. The state was allowed to prove, over the objections of defendants, threats made by Alexander MeKinzie against deceased as well as statements made by Alexander as to his connection with the difficulty, not in the presence or hearing of John MeKinzie. *632There was no error in this, they being tried jointly, and the court having told the jury in its instructions that these threats and statements should not be considered by them so far as John was concerned.
VIII. The evidence showed that defendants and deceased were at Jones’ saloon about midnight and, when informed that it was closing up time, they (the two defendants and deceased) went out of a back door of the saloon into a summer house near by, where the difficulty occurred, and the stabbing was done. Defendant, Alexander McKinzie, was sworn as a witness and testified in chief that he had no cane with him at the time, nor did he strike deceased with a cane: On cross-examination he was asked this question. “ Q. Were you sitting in the saloon there with your head down on a cane?” The defendants’ counsel objected to this question upon the ground that he had asked the witness about what occurred after he got out of the saloon and not about what happened in the saloon, and, therefore, that this question was in regard to a matter not referred to in the examination in chief. This objection was overruled and this is urged as error. This point is not tenable. Defendant was asked about his having a cane with him and using it in the fatal difficulty. His possession and use of the cane were the matters referred to in the examination in chief, and the state had a right to examine him fully as to his possession and use of a cane on the occasion of the homicide. We find no merit whatever in the objection to the cross-examination of John McKinzie.
IX. We have carefully examined the evidence in this case, and we believe the court below ought to have instructed the jury in regard to murder of the first and second degrees and manslaughter of the third and fourth degrees and self-defense. In this connection we will simply add that defendants may be guilty of manslaughter of the fourth degree, even though they intended to kill. If they acted without malice and in *633a heat of passion and not in self-defense they were guilty of manslaughter of the fourth degree, even though they wilfully killed deceased. R. S. 1889, sec. 3477; State v. Edwards, 70 Mo. 480 ; State v. Watson, 95 Mo. 411.
If the killing was involuntary and in a heat of passion, produced by a lawful provocation and without malice, and not in self-defense, then it is manslaughter of the third degree under section 3471, Revised Statutes, 1889. State v. Thomas, 78 Mo. 327.
We do not deem it necessary to decide whether the venue was proved or not, nor whether the jurors were permitted to separate to the injury of defendants. These alleged errors can be avoided at the next trial.
For the errors herein pointed out the cause is reversed and remanded for new trial.
All concur.
