This is an indictment for murder. The defendant was tried before a jury in the superior court and found guilty of murder in the first degree. The trial justice denied the defendant’s motion for a new trial. The case is before us on his bill of exceptions.
Annie M. Greene was a well-known schoolteacher who lived alone in a secluded part of the town of Exeter. She was killed in the kitchen of her cottage in the late afternoon of June 15, 1960. At the time of her death, Mrs. Greene, who was a widow, was approximately 70 years old. Her body was discovered at about 9:30 o’clock the following morning. Death was due to a hemorrhage and shock following multiple fractures of the skull. The fractures had been produced by numerous blows of a blunt instrument identified at the trial as a claw hammer.
Upon discovery of the body, the state police were summoned. They immediately commenced an investigation. The defendant had lived in Exeter and knew the deceased. He had been paroled from prison five days before the crime in question on June 10, 1960. These facts, together with defendant’s past record of crimes of violence made him a prime suspect. In the late afternoon the focus of the investigation shifted from Exeter to the city of Providence when the deceased’s station wagon was found abandoned on Westminster Street. Two hours later, defendant was apprehended in Providence and taken to that city’s police headquarters. He admitted killing Mrs. Greene and then driving her motor vehicle to Providence where he left it on Westminster Street. He was returned to the Greene property where he showed the police the location of the murder weapon. The defendant was then taken to the *326 state police barracks in Hope Valley where he signed three written statements 1 which expanded on the sketchy account he had given in Providence of his activities on June 15. The last statement given by defendant was obtained by the police after they had received certain information from the state pathologist relative to the autopsy performed on Mrs. Greene. In that statement, defendant said that he had raped the deceased and then killed her because she had said she was going to report his actions to the authorities. The defendant was charged with murder and the present indictment was returned by the Washington County grand jury during the latter portion of June, 1960. The defendant filed a general plea of not guilty and a special plea of not guilty by reason of lack of sufficient mental capacity.
The trial began in superior court November 21, 1960. One of the state’s witnesses was Captain Arthur J. Newton. This officer who was the head of the detective division of the state police was in charge of the investigation which led to defendant’s arrest. While under cross-examination, the captain testified that during the time this homicide was being investigated all of his subordinates (over 40 in number) rendered oral reports to him as to the manner in which they carried out their assigned duties.
Captain Newton said that he bad reduced these reports to writing and compiled them in a document which was on file in his office at state police headquarters in Scituate. Defense counsel thereupon made a motion that the trial justice order the witness to produce the document as an aid in his cross-examination of the witness. The trial judge denied this request. It is this denial which provides the basis for defendant’s first exception.
*327 I
Use of the State Police File for Impeachment Purposes
In urging that this file be made available to him, defendant relies on the holding in
Jencks
v.
United States,
Although the Jencks case is not binding in state courts, it has led to a consideration and reconsideration in several jurisdictions as to a defendant’s right to pretrial statements of the prosecution’s witnesses. It appears that various states are about evenly divided 2 as to whether they will or will not follow the federal rule.
*328
In Rhode Island we have no controlling decision on this question. We came close to it recently in
State
v.
Bradshaw,
101 R. I. 233,
.Let us now examine the applicability of the
Jencks
rule to the present case. In
Jencks,
the court described the basic requirements which must be established before the mo
*329
tion bo produce will be entertained by the trial court. In doing so, it cited
Gordon
v.
United States,
We think the Jencks case is clearly distinguishable from the one at bar. First, the documents sought in Jencks were reports written by witnesses as to events which the witnesses personally observed and about which they were testifying. In the present case, defendant seeks access to a document which is to a large extent a synthesis of reports made by officers other than the witness, most of whom were not scheduled to call to testify at the trial. Thus, the defense was seeking a report which was saturated with exclusionary hearsay and therefore outside the scope of Jencks. Secondly, in Jencks the motion for production was directed to a singularly identified, highly relevant and material set of documents which contained, theoretically at least, a written account of the precise matters about which the witnesses were testifying. In the instant case, however, defendant offered a blunderbuss motion for a report which contained heaps of irrelevant, meaningless, and unimportant detail about which the witness was not testifying. In effect, to permit defendant to probe the supervisory report prepared by Newton would have been equivalent to the issuance to defendant of a veritable license to engage in a fishing expedition of the type specifically proscribed *330 in Gordon. We therefore believe that the rule in Jencks is inapposite for purposes of this case and accordingly hold that the trial justice properly denied defendant’s request for the state police report.
Likewise, we also overrule defendant’s exception to the court’s refusal to allow counsel to ask a question of Captain Newton as to whether his recollection was as of the time of the investigation or at some later time. At the time this question was posed, the court was conducting an inquiry in the absence of the jury as to the voluntariness of certain answers given to certain questions by defendant in the Providence police station. Whether the witness was or was not testifying from memory was not germane to the issue then before the court, and defendant’s question was therefore irrelevant. The defendant did ask this witness several times while the jury was present if he had used the headquarters’ file to refresh his memory prior to his testifying in court. Captain Newton insisted that he had not. The witness stated that he was testifying from memory as to the events which transpired five months earlier. Accordingly, defendant’s exception above is overruled.
II
The Insanity Issue
In Rhode Island, a defendant, if he raises the issue of his' insanity, has the burden of proof with respect thereto and a court can instruct the jury that a presumption of the defendant’s sanity survives unless they are convinced that the defendant is insane.
State
v.
Quigley,
26 R. I. 263,
The defense thereupon introduced into evidence as full exhibits certain records of the department of social welfare. This is the department of state government charged with the operation of our penal institutions. Included among these documents were certain records of the department’s division of mental hygiene services. These records were the results of examinations made of defendant by the division’s psychiatrists and psycbometrists during the time defendant was in jail prior to his June 10 parole. The defense not only introduced the records into evidence but they were read aloud to the jury. Letters sent by defendant to various individuals while he was imprisoned in 1954-55 were also read to the jury.
The defendant took the stand. He admitted knowing the deceased and being in her home on the afternoon of June 15. He claimed that he had an argument with Mrs. Greene and then there was a “flash.” He claimed that he hit her once but did not know what happened thereafter; the next thing he remembered was driving the victim’s station wagon in Westerly. The defendant said he continued on to Providence and left the motor vehicle at the spot where the police found it. He denied having sexually assaulted the deceased.
After defendant concluded his testimony, Dr. Mezer took the stand as a rebuttal witness. He recited an impressive list of his qualifications. Once again he stated that he had prior to the trial studied the reports of the state’s psychia *332 trists and psychometrists, certain photographs and other material all of which were now in evidence. He stated that he had been present in the courtroom during the entire trial, had listened to all the evidence, including defendant’s testimony. Doctor Mezer then gave an opinion based upon the records in evidence and the testimony he heard that defendant was not suffering from any disease of the mind which would prevent him from knowing the nature and quality of his act or the difference between right and wrong.
The defendant contends that it was error for the superior court to permit the expert witness to give his opinion where it was based in part on the records of certain psychiatrists and psychometrists who did not testify. The use of such records, he claims, is a clear violation of the hearsay rule.
It is our belief that defendant takes nothing by this exception. His position on this issue is rather anamolous for, on one hand he urges that the reports introduced into the record at his instance are not competent evidence upon which Dr. Mezer can base an opinion as to defendant’s criminal responsibility, while on the other hand he asks us to believe that these same reports can be legitimately used by the jury in considering his burden in regards to his special plea of insanity. Nonetheless, this strange dichotomy is of no particular consequence here since we believe it is not necessary for us to reach a definite answer on this exception. For even assuming that the trial justice in permitting the psychiatrist to give his opinion was in error, we are unable to see how this prejudiced defendant. Our examination of the transcript fails to uncover one iota of competent evidence from which an inference could be drawn that at the time of the commission of the act complained of here, defendant did not have the mental capacity to know the wrongful nature of what he was doing. In our *333 opinion the presumption of defendant’s sanity remained with him throughout the trial.
In his brief defendant urged that we forsake the M’Naghten rule. In oral argument he conceded that the record is devoid of any evidence probative of the invalidity of the rule. This court in

The Charge to the Jury
The defendant’s remaining exceptions pertain to certain portions of the court’s instructions which relate to a definition of murder in the second degree and defendant’s special plea as to his lack of mental capacity.
The trial justice in her charge outlined to the jury three different degrees of homicide — murder in the first degree, murder in the second degree and manslaughter. At one point in her charge she described murder in the second degree as follows:
“Where premeditation appears to have existed only for a moment, that is, for a period of time too short to be measurable or appreciable in terms of time element, then the crime is murder in the second degree.”
It is defendant’s position that this was an erroneous charge. We disagree.
*334
It is now well established in this jurisdiction that for a homicide to be classified as murder there must be shown to have existed premeditation on the part of the accused. We have remarked in earlier cases that the key element in differentiating between first and second degree murder depends on the extent or amount of premeditation exhibited by the defendant’s actions.
State
v.
Prescott,
70 R. I. 403,
In reviewing the exceptions taken by a defendant to a trial justice’s instructions to a jury we are obliged to examine the charge as a whole and if, after doing so, we feel the trial justice correctly and fairly defined and described the law pertinent to the case at hand, we shall overrule the exception.
State
v.
Mantia,
101 R. I. 367,
As to defendant’s second exception to the charge, he in *335 vites our attention to a part of one sentence wherein the trial justice discusses the legal consequences of defendant’s special plea of lack of mental capacity. The defendant alleges that the court erred in telling the jury that his insanity plea admitted the act. The .entire sentence referred to by defendant reads as follows:
“Now, at the outset, when the defendant sets up insanity as a defense to a crime he is generally taken as admitting his act, but is denying any criminal responsibility for it on the ground, as his plea suggests, that he lacked at the time the necessary mental capacity to appreciate the nature and character and quality of the act or to know that what he did was -wrong.”
This portion of the charge recites a correct proposition of law which is set forth in
State
v.
Quigley, supra.
There we ruled that a not guilty plea does not bring the insanity of the accused in issue. Such an issue must he brought before the court by way of a special plea which is in the nature of one in confession and avoidance. It was pointed out in
Quigley
that the defense of insanity admits the act but not the crime. We hasten to add, however, that such an admission extends only and is limited solely to the consideration of a special plea beyond which it has no other efficacy in a criminal case. See
Leick
v.
People,
Again, in making the claim that this part of the charge absolved the state from proving the commission of the act, defendant failed to look, as we must, to the entire charge. State v. Mantia, supra. If he did, he would see, as we do, that the jury were told that they could not consider defendant’s special plea unless and until they had deemed him guilty of one of three possible offenses described in the earlier portion of the trial justice’s charge, to wit, murder in the first degree, murder in the second degree and manslaughter. The trial justice informed the jury in lucid and concise terms that essentially only two *336 issues were submitted to them for -determination. First, with regard to the killing of Mrs. Greene, they were to decide whether or not defendant billed her and if he did, was it unlawful and was there premeditation. Secondly, if their answers to the first issue were affirmative, then and only then were they to decide whether defendant was criminally responsible for his actions. While we believe that the use of the maxim “the plea of insanity admits the act but not the crime * * without further precautionary instructions could well imperil the rights of a defendant, it did not happen here. In her charge the trial justice unequivocally indicated that this admission was only for the purposes of the second plea and could not be considered until the jury was convinced that a crime had been committed.
Finally, defendant alleges that the superior court committed error in telling the jury that no claim was being made that defendant was “insane” at the time of the trial. While we believe that the trial justice’s use of the word “insane” was imprecise, it does not in our opinion constitute reversible error. The term insanity, as it is commonly used, signifies an unsoundness of mind, a derangement of the intellect which may be complete or partial and which can and often does vary from time to time.
