*424By the Court,
Coleman, J.:The appellants were convicted in the'district court of Mineral County upon a charge of murder, alleged to have been committed therein, and were sentenced to suffer the death penalty. A motion for a new trial and *425for an arrest of j udgment having been denied, an appeal was taken to this court.
The facts of the case as shown by the testimony of the state, and which the jury must have found to be true, are:
About 8 o’clock on the morning of August 28, 1921, a Chinaman known as Tom Quong Kee was found dead in his cabin at Mina, Mineral County, Nevada, with a bullet hole through his body. About a week before the defendants had spent one day in Mina. On the evening of the 26th of August, defendant Sing engaged one Pappas, of Reno, Nevada, a taxi driver, to take him and the other appellant on the next day to Tonopah. They left Reno in the morning, going by way of Virginia City, Yerington, and Hawthorne, and arrived at a point about a mile out of Mina around 8 or 9 o’clock in the evening. At that point Sing, who could speak English, directed Pappas to pull out of the road and await the return of the defendants, who left the car and walked in the direction of Mina. Pappas fell asleep, and was awakened about 10 o’clock by the horn of a passing car. Not having had anything to eat that day, except a glass of milk, which was in the morning, he started to drive to Mina to procure food. Meeting the defendants on the way, they got into the car, and proceeded toward town for a short distance, when Pappas was told to stop. After turning the car out of the road, he was given a dollar and directed to go into town and get some beer, which he did. He was gone thirty or forty minutes. Upon returning to the car he opened the beer, and each had two bottles, after which he was directed by Sing to return to Reno, where they arrived at 10 o’clock on the morning of August 28.
Upon discovery of the dead Chinaman on the morning of August 28, the deputy sheriff (Hamill) made an examination of the body and of the premises, and traced footsteps of two persons leading from the point at which the car stood when the beer was drunk to the cabin in which the Chinaman had been shot, and back *426to the same point, after which he called up the chief of police in Reno, informed him of the facts, and requested him to arrest Pappas and the two defendants upon their return to Reno, which was done shortly after their arrival. The two defendants were placed in jail, where the defendant Sing made a confession on the evening of the same day.
As occasion may require, this skeleton of facts will be supplemented in disposing of certain of the questions presented.
It is contended that the court erred in admitting in evidence the confession made by defendant Sing. This contention is based upon the theory that the confession was not voluntary, because one of the officers in whose presence he made it told him to “tell the truth; that the truth would be best for him.” Counsel -for the appellants say in their brief:
“Aside from the positive statement of the defendant Hughie Sing to the effect that they had promised to turn him loose if he would make a statement, the testimony of Officer Hamill, who was in fact in charge of the case, and more particularly interested, it appears undisputed that he told Hughie Sing that it would be better for him to tell the truth, and that Chief of Police Kirkley also made the same statement to Hughie Sing. This places the case squarely within the rule announced by this court in the cases of State v. Dye, 36 Nev. 143, 133 Pac. 935, State v. Urie, 35 Nev. 268, 129 Pac. 305, and State v. Carrick, 16 Nev. 129.”
We readily concede that if Sing was told by the officers that he would be turned loose if he made a statement, the confession would be involuntary, and that it should have been excluded. The fact is that Sing made his confession in the presence of Chief of Police Kirkley, Deputy Sheriff Hamill, and Police Officer Dean, all of whom deny that any such statement was made as testified to by the defendant Sing, to the effect that he would be turned loose if he made a statement. The lower court had a right to reject the statement of Sing, which *427it no doubt did — at least, we presume that it did. This leaves for our consideration whether the statement of the officers, under the facts and circumstances surrounding the making of the confession — that it would be better for the defendant to tell the truth — was such as to justify this court in saying that the confession was involuntary.
In the case of State v. Dye, 36 Nev. 143, 133 Pac. 935, it was held that the statement by the officer to the defendant, “If you tell the truth, it will be a whole lot better for you,” under all the facts and circumstances of.the case, was sufficient to warrant the conclusion that the confession was not voluntary. But it appears from the statement of the facts of that case that there were other elements entering into consideration which materially influenced the court in holding that the confession was involuntary. It appears that the defendant was considered as a tool of others, and that he was made to believe that he was so considered by the prosecuting witness and the sheriff, who said to him:
“Bill, you watch out for Bill Dye. * * * Bill, you ain’t to blame. It is others I blame. It is better for you to take care of yourself. * * * Bill, I want the principals in this proposition. It wouldn’t do me much good to send you to prison, for they could hire some one to do the job again. Bill, I want the head man in this.”
The foregoing is but part of the facts of that case going to show that there was influence brought to bear upon the defendant to justify the court in holding the confession involuntary. There is no such situation in this case. The testimony on the part of the state showed that on the evening of August 29 the defendant, who was in the city jail at Reno, was taken into the presence of Chief of Police Kirkley, Deputy Sheriff Hamill of Mineral County, and Officer Dean. Chief Kirkley stated to him that he wanted to talk with him, and told him that anything he might say could be used against him in court; that it would be best for him to *428tell the truth. He then asked him, “How did you come to get mixed up in this?” to which he replied, “Oh, I have been drinking.” The testimony on the part of the state is also to .the effect that no threats of violence or promises of immunity were offered, and that the defendant seemed perfectly composed and calm. Thus it appears that the defendant had notice that anything he might say could be used against him in court. It was a warning to him. He knew from this statement that he could expect no immunity. Then, does the mere statement that it would be better for him to tell the truth necessitate a conclusion that the confession was involuntary ?
The basis of the rule assigned for the exclusion of confessions made as the result of promises or threats is the unreliable character of the confessions made under such influences. The rule rests entirely upon the theory that confessions given under such influences are improbable. Counsel say that it is based upon the theory that a person charged with a crime shall not be compelled to be a witness against himself. Whether a witness who makes a confession can be said to be a witness against himself turns upon the proposition as to whether or not the confession is voluntary. In Huffman v. State, 130 Ala. 89, 30 South. 394, it was said:
“It does not render a confession inadmissible to charge a defendant with crime before he confesses it, ' nor to tell him it will be better for him to tell the truth, if he is guilty [citing authorities].”
It was held in Hintz v. State, 125 Wis. 405, 104 N. W. 110, that a judgment would not be reversed where a confession was admitted upon the representation to the defendant:
“You might as well tell the truth, Charlie. I think it .would be better for you.”
The Criminal Court of Appeals of Texas, in Anderson v. State, 54 S. W. 581, held that the statement to a defendant “that it might be better for her to tell the truth about it” did not warrant a reversal of conviction.
*429In State v. Brown, 2 Boyce (25 Del.) 405, 80 Atl. 146, it was held that a confession should not be excluded merely because the defendant was told:
“Tell us the truth; it will be better for you.”
In Lucasey v. United States, Fed. Cas. No. 8,588a, it was held that a confession was admissible in which the defendant was told that “it would be better for him to tell the truth.”
The Court of Appeals of Georgia, in Wilson v. State, 19 Ga. App. 759, 92 S. E. 309, held that a statement to the defendant that “it would be better for him to tell the truth about the case” would not justify the exclusion of a confession.
In State v. Meekins, 41 La. Ann. 543, 6 South. 822, it was held that the fact that the sheriff told the defendant “he had better tell the truth” would not justify the exclusion of the confession.
In State v. General Armstrong, 167 Mo. 257, 66 S. W. 961, it was said:
“It is the settled law of this state that a mere adjuration to speak the truth does not vitiate a confession.”
In State v. Allison, 24 S. D. 622, 124 N. W. 747, it was held that the statement by the sheriff to the defendant, “The best thing you can do is to tell the truth, and you might get out of it today,” did not justify the exclusion of the confession from the jury.
The same rule was declared in Fouts v. State, 8 Ohio St. 98, State v. Kornstett, 62 Kan. 221, 61 Pac. 805, and Wilson v. State, 19 Ga. App. 759, 92 S. E. 309. See, also, 1 Greenleaf, Evid. (16th ed.), sec. 220; 2 Wharton, Crim. Evid. (10th ed.), sec. 647; 1 Wigmore, Evid. sec. 832.
While there are authorities taking the contrary view, the rule stated is sustained by the greater weight of authority, and, we believe, by the better reasoning.
The objection urged to the admission in evidence of two certain pistols, found in the automobile in which the trip to Mina had been made, is without merit. In view of the uncontradicted testimony showing the *430presence of the defendants at Mina on the night of'the killing, the tracks leading from the place of the killing to where the defendants drank the beer, and all the other evidence, we are of the opinion that the admission in evidence of the pistols was not prejudicial to the defendants.
The next point urged relates to certain receipts found in the possession of Gee Jon, offered in evidence by the state. They do not purport to be for money paid by either of the defendants. The theory of the state is that they were for money paid to a tong by the defendant Gee Jon. When they were offered in evidence, counsel for the defendants said: “We have no objections.” In view of this statement, no error was committed by the court in admitting the receipts in evidence, and, being in evidence, no error could have been committed by the ruling of the court permitting their interpretation.
It is also contended that the court, in admitting in evidence a photograph showing a portion of the room in which the deceased was standing at the time of the shooting, with somewhat different conditions from those existing when the shooting was done, committed error. Technically speaking, the contention may be well founded, but under the facts of the case no possible prejudice would have resulted to the defendants, or either of them.
The remarks of special counsel for the state, during his argument, relative to tong wars, since there is nothing in the evidence connecting the defendants with them, were highly improper. Such remarks are unfair, and often lead to a reversal of a judgment of conviction and the burdensome expense of a new trial. A mere reprimand by the court, and an admonition to the jury to disregard such argument, do not always cure the injury. Trial courts should find some way of stamping out such gross abuses of the privileges of attorneys. However, we cannot say, in view of the entire record, that the defendants were prejudiced.
*431Error is assigned to the giving of instructions 11, 13, and 26. Instruction No. 11 reads:
“There are certain kinds of murder which carry with them evidence of premeditation and deliberation. These the legislature has enumerated in the statuté, and has taken upon itself the responsibility of saying that they shall be deemed and held to be murder in the first degree. Those cases are of two classes: First, where the killing is perpetrated by means of poison, or lying in wait, or torture, or any other kind of wilful, deliberate and premeditated killing, and here the means used is held to be evidence of premeditation and deliberation.”
This instruction was approved in the case of People v. Nichol, 34 Cal. 213, and was held by this court, in State v. Harris, 12 Nev. 414, to be devoid of error. We think no error was committed by the giving of the instruction.
Instruction No. 13 reads:
“The court instructs the jury that the rule of law which throws around the defendants the presumption of innocence and requires the state to establish, beyond a reasonable doubt, every material fact averred in the indictment, is not intended to shield those who are actually guilty, from just and merited punishment, but is a humane provision of the law, which is intended for the protection of the innocent, and to guard, so far as human agencies can, against the conviction of those unjustly accused of crime.”
We fail to see wherein the rights of the defendants were violated by this instruction. Similar instructions have often been sustained. Turner v. State, 102 Ind. 425, 1 N. E. 869; People v. Gerold, 265 Ill. 448, 107 N. E. 165, Ann. Cas. 1916a, 636; People v. Rees, 268 Ill. 585, 109 N. E. 473.
Instruction No. 26 reads:
“If you believe, from the evidence, beyond a reasonable doubt, the defendants * * * went to the place where Tom Quong Kee, deceased, resided, with the wilful and deliberate and premeditated purpose of taking his life, and that said defendants, with such intent, *432shot and killed the deceased, then and in that event the defendants are guilty of murder in the first degree.”
The objection urged to this instruction is that it does not advise the jury that they must find the killing to have been unlawful and with malice aforethought.
The court defined murder to be the unlawful killing of a human being, with malice aforethought, and followed that definition with an instruction substantially in the language of the statute, to the effect that all murder committed by means of poison, or lying in wait, torture, or any other kind of wilful, deliberate, and premeditated killing, or which shall be committed in the perpetration, or attempt to perpetrate, any arson, rape, robbery, or burglary, shall be murder in the first degree; and that all other kinds of murder shall be deemed murder in the second degree. But the court nowhere informed the jury that, before they could find the defendants guilty of the crime charged, they must find that they unlawfully and with malice aforethought killed the deceased.
As to the merits of the contention made by counsel for the defendants, the court is somewhat divided. Mr. Justice Sanders is of the opinion that, in view of the instruction defining murder, and of the other instruction as to the elements of wilful, deliberate, and premeditated killing, the court fully advised the jury as to the law of the case upon the particular phase in question, relying for support of his position upon the case of People v. Ye Foo, 4 Cal. App. 730, 89 Pac. 450, and People v. Mar Gin Suie, 11 Cal. App. 42, 103 Pac. 951; his theory being that by the instruction given the court was not defining murder, but expressly told the jury that, before they could find the defendants guilty of murder in the first degree, they must believe from the evidence beyond a reasonable doubt that the defendants went to the place with the preconceived, wilful, deliberate, and premeditated intent to take the life of deceased, and, with the intent thus formed, killed the deceased. On the other hand, Mr. Chief Justice Ducker and the *433writer are of the opinion that the essential elements of the crime of murder are the unlawful killing of a human being, with malice aforethought, and that the court erred in not embodying those elements in its instruction No. 26, or in some other instruction.
The Chief Justice, however, is of the opinion, in view of all the facts in the case and our broad statute to the effect that no judgment in a criminal case should be reversed for a misdirection of the jury when no substantial error results (as construed in State v. Willberg, 45 Nev. 183, 200 Pac. 476), that, as the court gave in its instructions the statutory definition of murder, no prejudicial error was done either of the defendants in omitting the elements of malice and unlawfulness from instruction No. 26, and that the judgment should be' affirmed as to both of the defendants; while as to the defendant Gee Jon, concerning whom admissions and statements of the defendant Hughie Sing are admittedly not competent evidence, as to whom the court instructed the jury to disregard said admissions -and statements, and against whom there is only circumstantial evidence, the writer does not feel justified in assuming the grave responsibility of saying that no prejudice was done by the failure of the court to embody in its instructions a definite requirement as to the elements mentioned.
It is also contended that the court erred in denying the application of the defendants for separate trials. The motion of Gee Jon for a severance is quite informal, and is based on the following statement:
“That upon the trial of this case certain testimony will be offered in evidence against the two defendants, which consists of the alleged admissions and statements made by his codefendant, Hughie Sing, to certain officers of the law, at Reno, Nevada; that such testimony is, in its nature, prejudicial to defendant Gee Jon, if said Gee Jon is tried jointly with the defendant Hughie Sing, * * * referring to the particular circumstances of the killing of the deceased.”
*434Counsel insist that the granting or refusing of a severance, where good cause is shown, is not a matter of discretion in the trial court, and to sustain this position direct our attention to the case of State v. McLane, 15 Nev. 345, wherein the court had under consideration a statute substantially the same as the one now relied upon. Stats. 1921, p. 165. It is true that the court held in that case that, had an application for a separate trial been aptly made, showing good cause for a severance, the application should have been granted. The court held, however, that the application in that case was too indefinite to disclose the real merits thereof, and that it was not made in apt time. In view of the construction put upon the statute then in existence, and its reenactment by the legislature in 1921, after another statute had been in force for some years, we feel bound by the conclusion reached in the case mentioned. However, we do not think the motion in the case before us presents good cause for a severance. The motion merely states that certain admissions or statements made by Hughie Sing, prejudicial in their nature to Gee Jon, would be introduced in evidence. The motion was objected to upon the ground that no showing had been made warranting a severance.
The motion of counsel is silent as to what fact or facts the alleged admissions and statements would tend to establish, except that they refer to the particular circumstances of the killing of the deceased. Nowhere does it appear in the showing made that Hughie Sing had made a statement to the officers that either of the defendants participated in the killing, or that either of them was present at the time of the killing. From all that appears from the motion, the statement made by Hughie Sing may have been favorable to the defendants. The motion formed no basis of fact from which the court could determine the existence of good cause for a severance; it stated a mere conclusion. The motion-of Hughie Sing is even less meritorious than that of Gee Jon. The court did not err in its rulings upon the motions.
*435It is also said that the evidence does not justify the verdict. We do not think we need review the evidence at length. It shows the presence of the defendants in Mina on the night of the killing; their mysterious conduct in stopping the jitney outside of town; their unsatisfactory explanation of their absence for a considerable length of time; the footprints lead-, ing from the jitney to the place of the killing and back to the place where the jitney stood; the presence of the two pistols in the jitney, and the unbelievable story told by the defendants, to the effect that the defendant Gee Jon was taken so sick that he had to turn back. We are convinced that the evidence justified the verdict.
It is also contended that the court erred in denying the mqtion in arrest of judgment. The motion was-based upon the assertion that the statute (Stats. 1921, p. 387), authorizing the execution of persons convicted of murder in the first degree by the use of lethal gas, is violative of the terms of the federal and state constitutions prohibiting the infliction of cruel or unusual punishment, and that the provisions of the statute authorizing the infliction of the death penalty in the manner mentioned is indefinite and uncertain as to the formula to be employed. The act in question provides:
“The judgment of death shall be inflicted by the administration of lethal gas. The execution shall take place within the limits of the state prison, wherein a suitable and efficient enclosure and proper means for the administration of such gas for that purpose shall be provided by the board of prison commissioners. The warden of the state prison must be present, and must invite a competent physician, and not less than six reputable citizens, over the age of twenty-one years, to be present at the execution; but no other persons shall be present at the execution.”
We are not in accord with either of the contentions. What has been the punishment for centuries for the crime of murder, of the character we know as murder in the first degree ? It has been death. For the state to *436take the life of one who perpetrates a fiendish murder has from time immemorial been recognized as proper, and as being neither cruel nor unusual. The act in question authorizes the taking of the life of a murderer as a penalty for the crime which he commits. It is the same penalty which has been exacted for ages— sanctioned in the old biblical law of “an eye for an eye and a tooth for a tooth.” It is true that the penalty has been inflicted in different ways; for instance, by hanging, by shooting, and by electrocution; but in each case the method used has been to accomplish the same end — the death of the guilty party. Our statute inflicts no new punishment; it is the same old punishment, inflicted in a different manner, and we think it safe to say that in whatever way the death penalty is inflicted it must of necessity be more or less cruel.
But we are not prepared to say that the infliction of the death penalty by the administration of lethal gas would of itself subject the victim to either pain or torture. Counsel say we must take judicial notice of facts and conclusions reached as the result of scientific research, and it is insisted that from the knowledge thus acquired we must declare that the law in question provides a cruel and inhuman method of enforcing the death penalty. Without undertaking to state the limitations of the rule invoked, we may say that, if we are controlled by our scientific knowledge of the subject, we must reject counsel’s contention. For many years animals have been put to death painlessly by the administration of poisonous gas. Gas has been used for years by dental surgeons for the purpose of extracting teeth painlessly. No doubt gas may be administered so as to produce intense suffering. It is also true that one may be executed by hanging, shooting, or electrocution in such a bungling fashion as to produce the same result. But this is no argument against execution by either method.
The revulsion on the part of many to the idea of execution by the administration of gas is due to an *437erroneous impression. The average person looks upon the use of gas with horror, because of the experiences incident to the late war. They forget that there are many kinds of gas, ranging from the harmless nonpoisonous tear gas, which may be used for the quelling of a mob, and the ordinary illuminating gas, which may produce painless death, to the highly poisonous gas which sears and destroys everything with which it comes in contact. It may be said to be a scientific fact that a painless death may be caused by the administration of lethal gas. That suffering and torture may be inflicted by its administration is no .argument against it. We must presume that the officials intrusted with the infliction of the death penalty by the use of gas will administer a gas which will produce no such results, and Will carefully avoid inflicting cruel punishment. That they may not do so is no argument against the law.
We think it fair to assume that our legislature, in enacting the law in question, sought to provide a method of inflicting the death penalty in the most humane manner known to modern science. If the argument made in behalf of the unconstitutionality of the act is sound, the legislature can provide no. method of inflicting the death penalty other than that now in vogue. In other words, science and progress must halt when face to face with a long-established usage. Such was not the spirit which prompted the incorporation into our organic law of the provision now invoked. Every enactment of our legislature must be deemed in harmony .with our constitutional provisions until the contrary clearly appears. The legislature has determined that the infliction of the death penalty by the administration of lethal gas is humane, and it would indeed be not only presumptuous, but boldness on our part, to substitute our judgment for theirs, even if we thought differently upon the matter.
We can find no ground upon which to sustain appellants’ contention. People v. Durston, 119 N. Y. *438569, 24 N. E. 6, 7 L. R. A. 715, 16 Am. St. Rep. 859; Storti v. Commonwealth, 178 Mass. 549, 60 N. E. 210, 52 L. R. A. 520. Nor do we find any merit in the contention that the act is indefinite and uncertain. It is certainly no more so than the act which it purports to amend. Rev. Laws, 7281. That statute simply said that the punishment of death should be inflicted by hanging the defendant by the neck until he is dead, or by shooting him, at his election. The present statute provides that the judgment of death shall be inflicted by the administration of lethal- gas, and that a suitable and efficient inclosure and proper means for the administration of such gas for the purpose shall be provided. We cannot see that any useful purpose would be served by requiring greater detail. Certainly, the statute infringes no provision of the constitution.
The judgment and order denying the motions for a new trial are affirmed, and the district court is directed to fix a time and make the proper order for the carrying into effect by the warden of the state prison the judgments rendered.
