The defendant has been convicted of the crime of murder in the first degree, and the penalty of death affixed. He appeals from the judgment upon the single ground that the court committed error in instructing the jury as to the law in two certain particulars.

The most serious objection of defendant is taken to the action of the trial judge in giving an instruction bearing upon the question of insanity. As to insanity the jury were told that the burden rested upon the defendant of proving his insanity by a preponderance of evidence. The principle of law thus declared is in full accord with the law of this state. For a period of thirty-five years this court has repeatedly and uniformly so ' declared the law to be. The cases to that effect are numbered by the score. We find the doctrine first announced in People v. Myers, 20 Cal. 518 , and we find this court in the recent case of People v. Bemmerly, 98 Cal. 299 , saying that the question is no longer an open one in this state. The law here declared by the trial court is also in line with the decisions of the courts of England, and also in accord with the views of the highest courts of more than one-half of the states of this Union. The defendant cites for our consideration Davis v. United States, 160 U. S. 469 . In that case the supreme court of the United States holds to views upon this question contrary to those we have so often declared; *83 but it is only necessary to say that upon a principle of law like the one here presented. we are not bound by the views of that tribunal.

The trial judge instructed the jury: “ The defense of insanity is one which may be and sometimes is resorted to in cases where the proof of the overt act is so full and complete that any other means of avoiding conviction and escaping punishment seems hopeless. While, therefore, this is a defense to be weighed fully and justly, and when satisfactorily established must recommend itself to the favorable consideration óf the humanity and justice of the jury, they are to examine it with care lest an ingenious counterfeit of such a mental disorder should furnish immunity for guilt.” There is no substantial legal objection to this instruction. In effect it has been given by trial courts and approved by this court in many eases. (People v. Dennis, 39 Cal. 637 ; People v. Bumberger, 45 Cal. 650 ; People v. Pico, 62 Cal. 51 .)

The judgment is affirmed.
