The defendants were charged by the district attorney of Sacramento county, upon information, with the crime of murder. They were tried jointly and convicted, and, under the verdict of the jury, the court sentenced Chin Plane to be hanged, and Hoey Yen Sing to be imprisoned for life. This is an appeal from such judgment, and from the order denying a motion for a new trial. The killing occurred at about the *601 hour of 10 p. m., in a building upon I street, in the city of Sacramento, at the inception or during the progress of an affray, carried on, very probably, by two rival Chinese societies, several Chinamen being killed at the time and others wounded as the result of the discharge of many firearms. The principal witnesses upon both sides of the case were Chinese, and, as is the universal rule in this class of cases, the evidence on the main questions involved was directly conflicting. There is no complaint made upon the law given to the jury by the trial court, and the grounds for appeal consist of twenty-three specific, numbered specifications of errors of law committed by the trial court, largely in the admission and rejection of evidence. Many of these specifications are exceedingly technical, and demand no extended consideration; others of more importance we will proceed to notice.

1. The party killed in the present case was one Lee Gong, and the prosecution, for the purpose of showing motive upon the part of the defendant Hoey Yen Sing, offered evidence, under objection, to the effect that the deceased was upon the bond of one Fong Ah Sheung, who had been charged with an assault to murder the said defendant Sing. The objection is based upon the ground that there was no evidence that the defendant Sing knew that the deceased had gone upon the bond. The objection, we think, goes to the weight of the evidence, rather than to its competency. We think it fairly inferable from all the facts and circumstances that he was. possessed of such information, but,, if he had no knowledge of the fact, then the evidence was entirely harmless, and no injury to him could have possibly resulted from its admission. The committing magistrate testified that Sheung was found not guilty of the charge of assault with a deadly weapon upon the day that Lee Gong was killed. It is now argued that this evidence tended to show the commission of another crime by the defendant Sing. We think no such inference logically follows from the evidence. From all that *602 appears by the record, Sheung, the defendant in that case, may have established an alibi, or some other defense equally inconsistent with guilt upon the part of this defendant Sing.

2. The prosecution claimed that the shots which killed the deceased were fired from inside the house. The defense insisted that they were fired in the open air. One Hill was near the scene of the affray at the time, and heard the shots. He was allowed to testify, under objection, that the shots sounded as though fired inside the building. He further testified that it sounded like it was a drum, or something deep. It did not sound like it was in the air. It is claimed that this evidence called for the opinion of the witness, and for that reason was not admissible. In the strict sense the evidence given was not the opinion of the witness any more than it was his opinion that the sounds were made by a drum. The evidence was simply a statement as to the nature of the impressions of sound left upon the ear, and, we think, clearly admissible. (See Robinson v. Exempt Fire Co., 103 Cal. 1 ; 42 Am. St. Eep. 93.) As ah additional reason for holding this assignment of error unsound, it may be suggested that the witness, without objection, had previously testified to the same effect. This fact would make the error harmless, if error had been committed .

3. The prosecution desired to introduce the deposition of one Lee Sam, taken at the preliminary examination, and placed a witness upon the stand, who testified to his efforts in trying to find the witness. Upon cross-examination the defense produced a photograph of the absent witness, and offered it to the jury for inspection. An objection was sustained to the course of counsel, and, we think, properly so. We know of no authority for such a practice. The evidence of the witness Lee Lick, and also that of Fay, bearing upon this question, in no way was prejudicial to the defendant’s rights, even conceding it to have been erroneously admitted.

4. It appears that, while the defendants were under *603 arrest and in jail for the killing, one Lee Sam came to the jail and identified them. When identified they each told Lee Sam, in the presence of the other, that they would kill him. This evidence was offered under objection. We deem it admissible. Threats made by a defendant against a witness whom he expects to testify against him, with the evident purpose of intimidating the witness, are proper evidence. The fact that the defendants were in custody at this time is wholly immaterial. The question was further asked the witness: “ Did you identify the defendants before the coroner’s jury?” He answered, under objection, that he did. Nothing was shown as to the conduct of the defendants when so identified, and it would seem that the answer of the witness should have been stricken out, upon motion, for this reason, but no motion to that effect was made. (See People v. Mallon, 103 Cal. 513 .)

5. Chief of Police Rogers testified, under objection, to a conversation occurring between Lee Sam, himself, and the defendant Chin Hane. The court admitted the evidence upon the ground that the defendant Chin Hane was sufficiently acquainted with the English language to understand all that was said, and did understand it. We see no error in this ruling.

6. Ah Wah testified, when upon the witness-stand, that she identified the defendants at the coroner’s office as the men who killed the deceased. The defense proposed to show by another witness who was present at the time of the identification that Ah Wah first pointed out another Chinaman as the guilty party, but upon objection the evidence was rejected. We do not think the witness could be impeached in this manner. Ah Wah should have been recalled, and asked with refer-, ence to the matter, and upon her denial of it the foundation would then have been laid for her impeachment by this witness’ testimony.

7. Lee Sam was an active friend of the deceased upon the night of the killing. A police officer testified that, subsequent to the killing, he arrested Lee Sam for car *604 rying concealed weapons, and found upon him two large pistols. The prosecution then asked the officer if he swore to a complaint, or prosecuted Lee Sam for carrying the weapons. An Objection to the question was overruled, and the officer said he did not know whether or not he swore to a complaint, but that the charge was subsequently dismissed. It is not at all clear that the evidence of the police officer, in the first instance, was material to the case at bar, but, if material, we think clearly the opposing side had the right to explain it. It may further be suggested that the defendants were not prejudiced by the action of the court in admitting the evidence.

8. It was not error for the court to exclude evidence of self-serving declarations made by defendant Chin Hane in San Francisco, immediately prior to his departure for Sacramento. We see nothing in the conduct of the district attorney, in his examination of the witness as to his past criminal record, demanding a reversal of the judgment. The witness Cheong, in reply to a question by the people, under objection, testified that he did not know of the police officer finding a trunk in his room with armor in it. The answer of the witness thus renders the question harmless, and defendants were not prejudiced.

9. The witness Lowell, after testifying that he made an examination of the deceased’s building after the killing, stated that he found several bullet marks upon the outside of the building. He then continued: “There was a bullet-hole in the door-jamb of Lee Gong’s, also. That was six or seven feet high. Some, also, on the brick wall, on the outside, on the edge of the brick wall. It seems to me as if that on the south side of the door there was a big chunk taken out of a brick. I am not positive. There is quite a large corner knocked off of a brick there.” The record further discloses as follows:

This excerpt from the record contains three questions by defendants’ counsel to which the court sustained objections. There appears to have been some little friction between counsel and the court at this particular time, an event not without precedent in the past; and we may be allowed to suggest that we think that counsel for defense could well have been more explicit in framing the questions asked, and that the court could *606 well have been more liberal in its treatment of these questions as asked. It is a very common practice to illustrate upon the wall or upon a door in a courtroom, before the eyes of the jury, the location of a bullet mark, and we think it may well have been done here. But such matters are largely in the discretion of the trial court, and, in the absence of an abuse of such discretion, we cannot interfere. The prosecution offered to allow the witness to describe the bullet marks, and we think the defendants must be satisfied with such offer. If the question addressed to the witness, “ Which way did it go, diagonally south or straight in? ” referred to the course of the bullet or bullet mark in the wood or brick wall (which is far from plain when we consider the context), then the objection that the question called for the opinion of the witness is not at all tenable, for he was simply asked to state something that he saw. It would be a statement based upon actual inspection, and, as far as we can see, entirely unobjectionable. But, beyond all this, the jury viewed these premises, and were particularly instructed to view these various bullet marks; and, taking all these matters into consideration, no grounds for a new trial; of the case are shown.

10. The witness Ah Wah testified that she was the wife of the deceased. She further testified as to her manner of life, habits, etc. The defense attempted to prove that she had been an inmate of a house of prostitution. The evidence was inadmissible. Such matters were entirely collateral, and her veracity could not be impeached in that way. The defendant Chin Hane, upon his direct examination, claimed to be a doctor. On cross-examination he was asked if he was not known in San Francisco as king of the highbinders. Under objection the question was not answered. Even conceding the question improper, the investigation in this direction here stopped, and nothing occurred of sufficient importance to reverse the judgment. In order to impeach the credibility of a witness, including a defendant when he testifies, the witness may be asked if he *607 has ever been, convicted of a felony. The details and circumstances comprising the offense should not be gone into. But, in view of the statute, section 2051 of the Code of Civil Procedure, which allows the proof of the fact to be made either by the evidence of the witness himself or by the record of conviction, it would appear that not only the fact of the conviction could be shown, but the name of the particular felony of which the witness had been convicted. Beyond this the examination should not go.

11. Under objection of the defense, the defendant Chin Hane, upon cross-examination, in answer to interrogatories, testified that he had never had any trouble with Jesse Jim (the party who discovered him to the officers after the killing), nor Ah Wah (deceased’s wife), nor the Lee family (to which the deceased belonged), nor the Chee Kong Tong. Under the facts forming the history of this case, we are inclined to think that this character of evidence would have been admissible, coming from the defense, as tending to show an absence of motive to do the killing. Objection was made to its introduction by the defense, upon the ground that it was not cross-examination ; and, especially in view of the fact that the witness testifying was the defendant, we think it should have been excluded if the court’s attention had been called to that fact. But, as we view this whole line of evidence, it was rather favorable to the defendant than otherwise, and no prejudicial error was committed.

12. In rebuttal the witness Cox, having known the defendant Chin Hane for many years in San Francisco, testified that he had never heard of him as a doctor. The motion to strike out this evidence was properly denied. While in its nature light, its weight was a question for the jury. The evidence of Clark in rebuttal, as to the identification by Ah Wah, was properly admitted. It is contended that the deposition of an absent witness, taken at the preliminary examination in a case of homicide, cannot be used at the trial, for the reason that such a proceeding is violative of section 13, *608 article I, of the constitution of the state. That provision of the constitution has been construed contrary to the appellants’ contention in the case of People v. Oiler, 66 Cal. 101 .

For the foregoing reasons the judgments and orders appealed from are affirmed.
