¶1The defendant was convicted of rape, committed upon a girl under fourteen years of age, and appeals from the judgment and an order denying him a new trial.
¶21. The demurrer to the information was correctly overruled. The offense was charged substantially in the language of the statute, and this was sufficient. *672(People v. Mills, 17 Cal. 276; People v. Burke, 34 Cal. 661.)
¶3It was not necessary to allege force by the defendant and want of consent of the child. Facts not required to be proven need not be alleged. In this instance, it was alleged that the offense was committed upon a female under the age of fourteen years, and, in such case, force and want of consent are immaterial factors in the offense. (Pen. Code, sec. 261; People v. Verdegreen, 106 Cal. 215.)
¶42. There is no tenable ground for the claim that the evidence does not sustain the verdict. The positive statements of the prosecutrix as to the facts, with the corroborating fact that the defendant was seen coming from her room at the unseemly hour of 5 o’clock in the morning on the occasion testified to, left only the question whether the jury would give credence to the testimony, and this is concluded by their verdict in the affirmative.
¶53. Nor do we find any error in the giving or refusal of instructions. The first complaint on this head is, that the court erred in submitting the case to the jury without cautioning them as to the danger of convicting the accused upon the sole testimony of the prosecutrix. In the first place, the failure to give such caution, even in a proper case, without its request at the hands of the defendant, would not constitute reversible error. But, in the next place, any suggestion of the kind in this instance would not have been pertinent to the case made by the evidence, since it did not rest upon the unsupported testimony of the prosecutrix. She was distinctly and materially corroborated by other evidence, and, under the circumstances, any such instruction might well have been construed by the jury as an intimation from the judge that he did not regard the corroboration as material or worthy of consideration, which would have been clearly improper. Furthermore, the judge did distinctly intimate to the jury that the testimony of the prosecutrix should be carefully scanned, and this *673was going as far in this regard as he was warranted under the circumstances.
¶6The jury were told that “ any penetration,” however slight, is sufficient in a case of rape; and it is urged that the instruction was erroneous because of the omission of the qualifying word “ sexual,” since it is only sexual penetration which will constitute the offense. But we do not regard the omission as material, in view of the other instructions defining the offense, and which, read in connection with the one under consideration, very clearly disclosed to the jury that it was sexual penetration which was referred to in the latter.
¶7There are no further objections under this head calling for particular notice. The defendant cannot be heard in criticism of the instruction upon the credibility of witnesses, even if erroneous, since it was given at his request, and, so far as the portion now criticised is concerned, in his own words. As to the requested instructions refused, they are fully covered by those given.
¶84. We do not regard the action of the court upon the effort of the prosecution to introduce evidence of acts of intercourse by the defendant with the prosecutrix other than the specific one charged, as prejudicial error, if error it be. The materially objectionable features of the evidence called out were not objected to, or any exception reserved; and, as soon as the purpose of the prosecution was made clear to the judge, any further inquiry in that direction was stopped, and in a manner which must have clearly indicated to the jury that it should consider only evidence as to the one act. But, furthermore, even if the objectionable evidence which did come before the jury was considered by them, we do not think, in view of the other evidence in the case, that the defendant could have been materially affected thereby, and the judgment should not therefore be reversed on that ground.
¶9The judgment and order are affirmed.
