The defendant was convicted of an assault with a deadly weapon, and appeals from the judgment and order denying his motion for a new trial. He claims the shooting to have been done in self-defense, and contends that the court committed error in its instructions to the jury upon the law of the case.

1. An exception was taken to the following instruction:

“If, however, you are satisfied from the evidence in the case, and beyond a reasonable doubt, that the defendant did, at the time charged and as charged, make an assault on one T. O’Connor with a deadly weapon— that is, one likely to produce, in the manner in which it is used, death or great bodily injury—with intent to do him great bodily injury, but are not satisfied that the assault was made with malice, or if you have any reasonable doubt whether such assault was with malice aforethought, your verdict will be guilty of an assault with a deadly weapon.”

Counsel say: “ Suppose defendant had assaulted the prosecuting witness with a deadly weapon with intent to do him great bodily harm; if it had been done in necessary self-defense he was entirely justified. Yet this instruction clearly directs the jury to find him guilty if such assault alone be proven.” A complete answer to this supposition is, that no such a state of facts could exist. One person cannot assault another in *231self-defense. An assault in itself is unlawful, and any act done in self-defense cannot be an assault.

2. The court gave the following instruction:

“ The bare fear that the said T. O’Connor, if defendant had had such fear, was going to inflict bodily injury upon the person of the defendant would not justify defendant in attempting to take the life of the said T. O’Connor, if he did so attempt; but there must have been some act or acts of the said T. O’Connor such as would induce an ordinarily prudent man to believe that he was in great and immediate danger of death, or great bodily injury, at the hands of the said T. O’Connor; and, unless you so find, you will find the defendant guilty.”

We think the instruction entirely correct. To be sure, it says nothing about threats, but threats alone never justify a homicide. Words, however grievous, do not even reduce a homicide from murder to manslaughter. While threats are always admissible as evidence, yet some act or acts of the deceased indicating danger to the defendant as a reasonable man, at the time of the shooting, must be present, or the plea of self-defense will be made in vain. The instruction in no way intimates that threats of the prosecuting witness toward the defendant are not admissible as evidence tending to throw light upon the circumstances surrounding the moment of the affray.

3. The following instruction was asked by the defendant and refused:

“ The court further instructs the jury that Sacramento street is a public highway in the city of Stockton, and that the defendant had a perfect right to be on said highway at the time and place where he was met by the prosecuting witness, and was under no necessity to leave or depart from said street in order to avoid meeting with the prosecuting witness, and, in the absence of evidence showing that defendant was in said street for improper and unlawful purposes, the court instructs you that the presumption of law is that the defendant was *232in said street at the time and place where he was met. by the prosecuting witness for a lawful and legitimate purpose.”

In the abstract we are not prepared to say that the mere fact of a man walking upon a public street justifies the presumption that he is there for a lawful purpose. But in the present case, where the defendant was charged with a crime committed upon the public street, we see no legal objection to this instruction, and perhaps it would have been the better course to have given it. At the same time, it was but another form of instructing the jurors that the defendant is presumed to be innocent until he is proven guilty, and that matter was fully explained to them in other portions of the charge.

4. Defendant testified that some days prior to the alleged assault, the prosecuting witness, among other things, said to him, “ I’ll fix you.” His attorney then asked him, “ What did you understand him to mean by those words?” and an objection was sustained to this question. We assume the purpose of the question was to show that defendant construed the language as a threat of physical injury, and, without deciding the merits of the ruling of the court in this regard, it is sufficient to say we think the defendant was not injured to any degree by such ruling, even conceding that his answer to the interrogatory would have been as indicated. A threat of the prosecuting witness at this time could only be material as bearing upon the circumstances immediately surrounding the shooting, and material only for the purpose of indicating that the defendant fired in self-defense. But the defendant further testified that immediately prior to the affray the prosecuting witness in a violent manner said to him, “ I’ll kill you,” and made demonstrations as if to draw a weapon. Under these circumstances it is plain that defendant was not injured before the jury by the ruling of the court, whatever may have been his understanding of the language used by the prosecuting witness.

*233Defendant complains of other rulings of the court, both as to instructions given and refused, and also as to evidence admitted and rejected, but after careful consideration we see no error, and find nothing further demanding extended notice.

It is ordered that the judgment and order denying a new trial be affirmed.
