After a trial to the jury, the defendant was found guilty of one count 1 of risk of injury to a child in violation of General Statutes § 53-21. 2 *86 On appeal, the defendant claims that the trial court erred: (1) in admitting evidence of alleged prior uncharged sexual acts of the child victim with the defendant and, if admissible, in not charging the jury of the limited purpose for which such evidence could be used; (2) in admitting hearsay statements for purposes of constancy of accusation and, if admissible, in not charging the jury on the limited purpose for which such evidence could be used; and (3) in refusing to allow the defendant to cross-examine the child victim, for the purpose of attacking her credibility, concerning whether she had made allegations of similar sexual misconduct against others.
For the purposes of our analysis, it is unnecessary to go into the sordid details of this case. It suffices to point out that the evidence presented showed that, on June 29,1979, the defendant performed certain sexual acts upon the victim, as well as having the victim perform acts upon him. At the time of this incident, the victim was eight years old. Also at that time, the defendant was the live-in boyfriend of the victim’s mother. It is evident from our examination of the record and the transcript that credibility was crucial in this case.
The defendant challenges, inter alia, the admission and use of the victim’s statements during the trial that the same thing had happened “[ajbout ten [times],” first starting when she was six years old. 3 The defendant *87 is also challenging the testimony of the victim’s mother who stated that the day after the incident in question, her daughter told her that this had happened more than once, starting when the defendant lived with them in Cromwell, which was about one and a half to two years before June 29, 1979. In addition, the defendant is challenging the testimony of police officer Henry Orzel who interviewed the victim the day after the incident, who testified that the victim had “related that [the assaults] occurred ... off and on since she was six years old.” Finally, the defendant is challenging the admittance of a hospital report of the victim that contained, inter alia, notes of the emergency room interviews which recorded the mother’s statement that the victim was repeatedly molested by the defendant. 4
For the purpose of complementing the situation from which the defendant’s claims arise, we must refer to certain rulings by the trial court. Prior to the offering of any evidence, the state told the court that the victim’s signed statement to the police included her claim that the defendant’s brother-in-law had committed similar acts upon her on several occasions in the past. It was pointed out that the defendant wanted to cross-examine on this matter although the state said that'it did not plan to go into the victim’s sexual activity on direct examination other than that with the defendant. The defendant claimed that such an examination of the victim here would go to her credibility in her accusation of the defendant, maintaining that the police report *88 did name the brother-in-law as also having done similar acts. The state told the court that the brother-in-law had disappeared “[according to the [victim’s] mother.” The court ruled that the defendant could not cross-examine the victim in that regard as the court did not “think it makes any difference that someone else has also been accused of the same act” and that it was “irrelevant.” 5
Immediately thereafter, the state said that there were further statements by the victim that the “defendant had engaged in similar type activity, sexual activity, with her on several occasions previous to this going back ... to the time when she was about six years old.” It claimed their admissibility under
State
v.
Greene,
After the state had started to put on its case and before the victim testified, the defendant renewed his claim on the admissibility of the prior acts that allegedly took place between the victim and the defendant. He *89 argued that the prejudicial value in their admission far outweighed their probative value, that such acts did not go to add to constancy of accusation and that constancy of accusation concerned only the crime charged. The court again ruled against the defendant saying that such evidence was allowed in the Greene case. 6 It also stated that “I’ll limit them just to the fact that they go to the weight and not to the — the weight to be given to credibility and not to whether or not they actually occurred. They will be limited to that purpose.” On direct examination the victim testified concerning the alleged prior acts with the defendant without any comment by the court to the jury involving their limitation. On direct examination the victim’s mother testified that the victim told her of the prior acts of the defendant as did officer Orzel. There was no comment by the court to the jury, as they testified, as to any limitation on the use of such testimony.
Just prior to the state’s resting its case, the defendant argued that the jury should have been cautioned, at the time the evidence came in, of the limitation of the use of evidence of prior acts. It was the court’s recollection, as well as that of the state, that it had not said it would so admonish the jury and it did not do so. 7 The court at that time also said it would charge the jury on the constancy of accusation exception pointing out “that’s when they get the limited purpose of *90 the accusations, but not as an admonishment to them during the course of the trial, not to prove the truth of all of the other incidents, only to prove the truth of this particular incident. . . . They will get it in their charge. That’s when I will give it to them.” 8
We turn to the defendant’s first two claims which are interrelated as the evidentiary rulings admitting the evidence complained of implicate the issue of constancy of accusation. In the first instance, the defendant asserts error in the admission of evidence of uncharged similar prior .sexual acts upon the victim by the defendant through the victim, her mother, officer Orzel and the hospital record. He then claims that even if such evidence were admissible, the court erred in not instructing the jury on the limited purpose for which it could be considered by them in passing upon his guilt or innocence of those crimes for which he was in fact charged and tried. We find error.
It is apparent from the transcript of the trial, the briefs and the arguments before us that the evidentiary rulings on this branch of the case involved our opinion in
State
v.
Greene,
supra. In that case the defendant was charged with crimes of carnal knowledge of a minor female and indecent assault.
State
v.
Greene,
supra, 292. There is language in that case which, although laconic, is expansive in tone and which could have been, and was, applied by the trial court, without great strain, to the circumstances of this case. Specifically, the court there stated: “The first contested evidential ruling was one which permitted the complaining witness to testify that the defendant began having sexual intercourse with her when she was eleven years old and that it happened every week. The other permitted her sister-in-law to testify that the complaining witness had shown her the marks on her neck and
*91
told her about the fight with the defendant, that he was the father of her child and that they had frequent sexual relations. We find no error in the rulings of the court, predicated on such cases as

unlike the case before us, was tried to the court and not to the jury. In trials to the court, where admissible evidence encompasses an improper as well as a proper purpose, it is presumed that the court used it only for an admissible purpose;
West Hartford
v.
Talcott,
We take up first the issue of the victim’s testimony of the prior uncharged crimes of similar sexual acts performed upon her by the defendant. Such testimony was not hearsay as she was relating something of which she had personal knowledge. The “constancy of accusation” doctrine is an exception to the hearsay rule that permits
witnesses
to whom a victim has complained of the offense charged to testify as we have pointed out above. In
State
v.
Brice,
This, however, does not end our inquiry here because the fact that the ground upon which the trial court admitted this testimony was improper does not make its admission erroneous.
Witek
v.
Southbury,
In
State
v.
Sebastian,
The state argues that the total of eight words in the victim’s responses to four brief questions of the defendant’s prior sexual misconduct does not even raise apparent harm. Moreover, the state argues that such testimony “could not probably have affected the verdict.”
10
The devastating effect of a ten year old child’s testimony reasonably bears no relation to its brevity. This is especially true in the complete absence of any limiting instruction as to its use. “Since the likelihood that juries will make such an improper inference [that a jury may infer that evidence of one crime proves the disposition to commit the crime charged] is high, courts presume prejudice and exclude evidence of other crimes unless that evidence can be admitted for some substantial, legitimate purpose.”
Drew
v.
United States,
We now turn to the testimony of the victim’s mother, the police officer, and the statements in the hospital report, all of which referred to statements made by the victim of prior uncharged sexual assaults committed
*97
upon her by the defendant. The introduction of all this evidence was claimed as admissible by the state as coming within the “constancy of accusation” exception to the hearsay rule. There can be no serious question concerning the viability of the “constancy of accusation” exception to the hearsay rule in sex-related cases in this jurisdiction.

See, e.g.,
State
v.
Hamer,
*98
In
State
v.
Brown,
The exception of recent contrivance, which we found inapplicable in State v. Brown, supra, 609, and State v. Dolphin, supra, is applicable in this case. Before a court, however, may admit prior consistent statements in response to impeachment on the ground of recent contrivance, the court must find: (1) that the prior statement was made at a time when it would have been natural to make it, independent of its potential use in court; and (2) that the witness has been impeached by a suggestion of recent fabrication.
Statements admissible under constancy of accusation are actually a subcategory of prior consistent statement evidence. When analyzed as prior consistent statements
*99
admissible to rebut a suggestion of recent fabrication, the confusion surrounding the admissibility of constancy of accusation evidence is reduced. The rationale for admitting hearsay declarations as constancy of accusation evidence has been stated as follows: “ ‘If a female testifies that such an outrage has been committed on her person, an enquiry is, at once, suggested, why it was not communicated to her . . . friends. To satisfy such inquiry, it is reasonable that she should be heard in her declarations, that she did so communicate it ... . [S]uch a course [of conduct] would be natural if the crime had been committed, but very unnatural if it had not been.’ ” (Citations omitted.)
State
v.
Segerberg,
Because the rationale of the constancy of accusation exception so clearly suggests the recent contrivance or fabrication exception, there is no analytical reason to approach them differently. Before either kind of evidence can be admitted, the trial court must find, under the circumstances in each case, first that the statement was made at a time when it was natural to make it; second that the witness has been impeached by a suggestion of recent contrivance. See
Commonwealth
v.
Byrd,
In this case, the victim’s testimony did not concern the crime charged and was therefore not an “accusation” as that word is used in the cases. A review of our cases on constancy of accusation; see
State
v.
Brice,
Finally, we take up the claim that the court erred in refusing to allow the defendant to cross-examine the victim on whether she had made complaints of similar *101 sexual misconduct against others. 13 The defendant claimed it on the ground of credibility. 14 The court, as noted above, said that it made no difference that someone had been so accused and that it was irrelevant.
“Cross-examination is the principal means by which the believability of a witness and the truth of his testimony are tested.”
Davis
v.
Alaska,
The trial court enjoys a liberal discretion in fixing the limits of cross-examination, particularly if it affects credibility.
State
v.
Croom,
*103
The court’s ruling in limine barred the defendant from cross-examining the victim at all on a matter of substantial relation to her credibility in this sex-related case where credibility was crucial. Her written statement to the police disclosed that she claimed that the defendant’s brother-in-law had performed similar sexual acts upon her on occasions in the past. She had never reported any of these to anyone she naturally would have. She kept silent.
15
This was patently relevant to her credibility. In arguing for the right to cross-examine on this, the defendant claimed he wanted to explore whether her claim was fact or “a child’s imagination” as well as to inquire concerning the number of complaints she may have made. “Sexual fantasy” is a basis for “broad cross-examination” of the complainant in sex cases. See

Francis,
There is error, the judgment is set aside and the case is remanded for a new trial.

Notes
The defendant was tried on a two count information. The jury returned a verdict of not guilty on the count charging sexual assault in the second degree in violation of General Statutes § 53a-71 (a) (1).
General Statutes § 53-21 provides: “injury or risk of injury to, or impairing MORALS OF, CHILDREN. Any person who wilfully or unlawfully causes or permits any child under the age of sixteen years to be placed in *86 such a situation that its life or limb is endangered, or its health is likely to be injured, or its morals likely to be impaired, or does any act likely to impair the health or morals of any such child, shall be fined not more than five hundred dollars or imprisoned not more than ten years or both.”
The questions and answers here were:
“Q. Now, had [the defendant] ever done this to you before?
“A. Yes.
“Q. Same thing?
“A. Yes.
*87 “Q. How many times?
“A. About ten.
“Q. How old were you when it first started, if you remember?
“A. About six years old.”
This testimony was given on the first day of the trial.
The first sentence in the interviewer’s note reads as follows: “Pt. is an 8 yrs. [old] white female brought to the E.R. after her mother today learned that pt. had been sexually molested repeatedly by her (the mother’s) boyfriend.”
The defendant excepted to this ruling and the court, upon inquiry by him, told him it would not be necessary to make another objection and exception to preserve the record when the matter came up.
In the same colloquy the court said that in Greene this court “specifically said the testimony of prior, similar sexual activity was permissible. That’s all they said. They didn’t say why. . . .”
At that point the defendant was arguing that if such evidence was allowed in for all purposes, “we haven’t been allowed to defend ourselves on these other eight or ten dates. We don’t even know the dates.”
The court observed at that point: “It’s not admitted for proving the truth of the other incidents, which are not in issue. It only goes to prove this incident, which is what you’re defending on. But it’s constancy of accusation for the purpose of showing that this particular incident occurred.”
The court granted the defendant an exception.
In arguing the admissibility of this evidence, the state said: “And I make my claim under
State
v.
Greene,
161 Conn. [291,
The questions and answers here were:
“Q. Now, had [the defendant] ever done this to you before?
“A. Yes.
“Q. Same thing?
“A. Yes.
“Q. How many times?
“A. About ten.
“Q. How old were you when it first started, if you remember?
“A. About six years old.”
This testimony was given on the first day of the trial.
The defendant’s brief states: “The defendant took exception to the charge . I objected during the initial — during the course of the trial to allowing the child to go into testimony of other acts, an alleged ten or eleven times, I believe. There’s nothing in the charge to limit that to constancy of accusation or as tending to prove this one act. The jury is left to just consider the whole aspect. . . ” (Emphasis added.)
This viability persists although the statutory requirement of corroboration was repealed by Public Acts 1974, No. 74-131 of the 1974 Session of the General Assembly.
Although this specific issue is not set out in the preliminary statement of issues, it was an issue at the trial and was decided by the trial court and it has been briefed and argued by the parties and we will consider it in this case. Practice Book §§ 3012 (a), 3060F, 3063;

General Iron & Welding Co.,
In arguing for the right to do this the defendant told the court that the police knew, from the written statement given them and signed by the victim and her mother, that she had accused a brother-in-law of the defendant of committing similar acts upon her in the past.
Her motive for doing so, i.e., fear, which the state could seek to explicate on redirect, should not be a bar to permitting any of this testimony as the court could control the extent of the cross-examination.
