¶1Defendant was charged by information with sodomy per os, an offense proscribed by Sec. 563.230, RSMo 1969. Trial to a jury resulted in a verdict of guilty. The trial court, in view of the jury’s inability to agree thereupon, assessed defendant’s punishment at ten years imprisonment.
¶2The unsavory nature of the facts, coupled with defendant’s tacit concession of their sufficiency to sustain the guilty verdict, makes minimal reference to them highly appropriate.
¶3The state presented evidence from which the jury could find beyond a reasonable *828doubt that on two occasions on July 10, 1975, defendant inserted his penis into the mouth of his eleven year old daughter. On the latter occasion, defendant ejaculated into the pathic’s mouth and she spat the exudate onto the basement floor. A chemical analysis thereof, although failing to reveal the presence of any sperm cells, did reveal the presence of acid phosphatase, a material produced by the male prostate gland and a constituent of seminal fluid. Pure saliva does not contain acid phosphatase. Although it was acknowledged that certain ingestible vegetable matter reacts weakly to acid phosphatase tests, the sample of expectoration under analysis reacted strongly and positively to an acid phosphatase test.
¶4A single point is advanced by defendant on appeal — error in not permitting him to inquire of the prosecuting witness on cross-examination as to whether she had previously made similar accusations of sexual assaults upon her by others.
¶5Judgment affirmed.
¶6All concur.
¶7. By way of general observation defendant failed to refine his point to the extent of charging that the “similar accusations” referred to were false and mere fabrications of the prosecuting witness’s mind. In view of his failure to do so, sound authority exists to exonerate the trial court of any error in limiting defendant’s cross-examination of the eleven year old prosecuting witness. See 75 A.L.R.2d 508; and People v. Pacheco, 220 Cal.App.2d 320, 33 Cal. Rptr. 735 (1963).
