On his appeal to this Court, the defendant contends that there were errors in the trial of this action in the Superior Court which *726entitle him to a new trial. He contends that there was error in the admission of evidence offered by the State, and in instructions of the court to the jury. These contentions cannot be sustained.
Eor some time prior to 14 August, 1935, the defendant and his wife were living separate and apart from each other. She was living with her parents at Edenton, N. C. His efforts to induce her to return to his home had been futile. Evidence offered by the State tended to show that the separation was caused by defendant’s mistreatment of his wife. He insisted that her refusal to return to his home, and to resume marital relations with him, was the result of the influence of her parents upon her. From time to time he expressed his resentment of this situation.
Some time between 7 and 8 o’clock on the morning of 14 August, 1935, the defendant went into Edenton Cotton Mill, where he knew his wife was at work as an employee of the mill. After talking to her for a few minutes, without provocation he assaulted and killed her by cutting her throat with a razor. She died almost immediately after receiving the fatal wounds. After cutting his wife’s throat, the defendant inflicted wounds on his own person, with suicidal intent. Evidence offered by the State tended to show that the homicide was murder in the first degree, the murder having been committed by the defendant, after premeditation and deliberation. See C. S., 4200. The defendant offered no evidence. He relied upon his contention that at the time of the homicide, he was incapable of premeditation and deliberation because of his mental condition, and that at most he was guilty of murder in the second degree only.
The evidence offered by the State, and admitted by the court over objections by the defendant and subject to his exceptions, tending to show that at the time of the homicide the defendant was of sound mind, and fully capable of premeditation and deliberation, was competent for that purpose. It is well settled as the law of this State that “any witness who has had opportunity of knowing and observing the character of a person whose sanity or mental capacity is assailed, or brought in question, may not only depose to the facts he knows, but may also give in evidence his opinion or belief as to the sanity or insanity of the person under review, founded upon such knowledge and observation, and it is for the jurors to ascribe to his testimony that weight and credibility which the intelligence of the witness, his means of knowledge and observation, and all the circumstances attending his testimony may in their judgment deserve.” S. v. Keaton, 205 N. C., 607, 170 S. E., 27.
The evidence offered by the State, and admitted by the court over objections by the defendant and subject to his exceptions, tending to show that about four weeks before the homicide, and before she had left his home, the defendant on one occasion ran after his wife and threat*727ened to cut her with a knife, was competent as tending to show a circumstance which the jury could properly consider as tending to show that the homicide was committed by the defendant after premeditation and deliberation, as contended by the State. S. v. Foster, 130 N. C., 666, 41 S. E., 284.
In his charge, the judge instructed the jury as follows:
“Now, gentlemen of the jury, the defendant did not see fit to offer any evidence. I charge you that he was within his rights in so doing. The law does not require the defendant to go on the stand as a witness. He has a right to sit mute and say nothing.
“Some people on the street say that if a defendant is not guilty, he will prove it, and will go on the stand for that purpose, but tbe law does not say so, and I charge you tbat you are not to consider tbe fact tbat tbe defendant did not go on tbe stand as a witness as any evidence of bis guilt. Tbe law says tbat be cannot be forced to go on tbe stand, and I so charge you.”
We find no error in this instruction of wbicb tbe defendant can complain. O. S., 1799.
As tbe trial of tbe action in tbe Superior Court is free from error prejudicial to tbe defendant, tbe judgment must be and is affirmed.
No error.
