OPINION
The defendant-appellant, George Leonard Ledford, was indicted for second degree murder as the result of his wife’s death at their rural Marshall County home on the night of May 26, 1976. Upon the defendant’s motion, venue was transferred to Bed-ford County, where Ledford was subsequently tried and convicted by a jury of second degree murder and was sentenced to 30 years imprisonment. On appeal, the defendant raises multiple assignments of error, the most serious of which concern (1) the sufficiency of the evidence to support the verdict, (2) the trial court’s failure to grant a mistrial following the prosecutor’s comment during closing argument on the defendant’s failure to take the stand, and (3) the exclusion of certain entries in the defendant’s hospital records. For the reasons set out below, we conclude that the case must be remanded for a new trial.
The factual issues litigated at trial were sharply drawn. It was the State’s theory that Ledford shot his wife and then set about to make it look as if the crime had been committed by an unknown intruder. The defense theory was that a burglar had forced open the kitchen door to the Ledford home, and, in some order, murdered Mrs. Ledford, beat Mr. Ledford senseless, and ransacked the house. Ledford, semi-conscious, bloodied and apparently beaten, was found in his kitchen the next morning by a tenant farmer. Whether his wounds were self-inflicted, as the State contended, or were sustained as the result of an assault by an unidentified assailant, as the defendant maintained, thus became the central issue of the trial.
The defendant was hospitalized as a result of his wounds, and, in a statement to police shortly after the homicide, he said that he and his wife had returned from an early evening visit and that he had gone to bed at 9:30 p. m., leaving his wife in the den watching television. He said that he was later awakened by a masked intruder who threatened him and beat him until he lost consciousness. He claimed that he could remember nothing until he came to in the hospital. (An ambulance attendant later testified that Ledford was not unconscious when transported to the hospital, because he was not completely limp; the attending physician, however, described Ledford as “comatose” on his arrival at the hospital.) Ledford maintained in his statement to police that he did not hear any shots fired. Medical testimony indicated that Mrs. Led-ford died from two .38 caliber gunshot wounds to the head, either one of which was fatal, both entering near her left ear and exiting through her right ear canal. An autopsy performed on the victim also *115turned up a six inch laceration to her scalp, which she suffered prior to her death from the gunshot wounds.
The defendant’s brother, Carl Ledford, had himself been indicted and acquitted of murdering his wife prior to the homicide in this case. During those proceedings, Leonard Ledford had been made his brother’s conservator, and had subsequently been sued by his brother for an accounting. That lawsuit resulted in a $13,000 chancery judgment against the defendant, which remained unsatisfied at the time of the victim’s death in this case. In his statement to police, Leonard Ledford said that before physically attacking him, his assailant demanded to know the whereabouts of the “Carl money”. It was the defendant’s additional theory that his wife had been killed because her interest in the farm property as a tenant by the entirety was an impediment to the successful execution of a lien against the property in satisfaction of the judgment secured by Carl Ledford.
Although there was no evidence whatever of any ill will between the defendant and his wife, the State made an unsuccessful attempt to show an improper relationship between the defendant and his middle-aged bookkeeper, and then argued to the jury that Ledford’s motive in killing his wife was to secure clear title to the farm property-
The State also introduced proof that in early July, some six weeks after the murder and at about the same time the local grand jury was scheduled to meet, the defendant left Marshall County and went to Dayton, Ohio, where he registered at a motel under an assumed name. When no indictment was returned, the Marshall County Sheriff swore out an arrest warrant on July 17, and the defendant was arrested in Ohio and brought back to Tennessee. (An indictment was returned against him the following November.) The State insists that the defendant’s conduct amounted to flight and that this circumstantial evidence, together with the fact that he was the only known witness to the murder, is sufficient to sustain the jury’s verdict, assuming the jury aecept-ed the State’s theory that the defendant’s wounds were self-inflicted. The defendant offered no explanation at trial for his so-called “trip to Ohio.”
In addition, the State produced three expert witnesses from the F.B.I.’s laboratory in Washington, D. C., who testified concerning tests conducted on some 32 items of physical evidence submitted to them, including wood splinters, hair samples, fingernail scrapings, pillows and other items of furnishing, blood samples, floor scrapings, rug fibers, clothes taken from the victim and the defendant, a .38 caliber gun and six .38 caliber bullets found in the Ledford home, and bullet fragments and slugs involved in the shooting. The resulting testimony was a virtuoso demonstration of expertise, but it produced not a single item of direct evidence tending to inculpate the defendant and only one item of arguably incriminating circumstantial evidence: an expert testified that one of the two bullets which caused the victim’s death had the same composition as one of the six bullets found in the Ledford home, from which the expert deduced that the two bullets were probably produced by the same manufacturer out of the same “batch.” The manufacturer, however, produces some 16 million bullets a day, according to the expert’s testimony.
The murder weapon was never identified.
It is clear that the State’s case was built entirely on circumstantial evidence, and we know of no better way to describe it than to say it was an extremely close case at best. There was uncontroverted proof that the Ledfords’ kitchen door had been forced open and that the house had been partially ransacked. The police testified that because some drawers had been rummaged while others were left unopened, and because the alleged ransacking in some instances appeared to have been done “neatly,” they came to disbelieve the defendant’s “mysterious intruder” story. They also concluded that the defendant’s wounds were “probably” self-inflicted, theorizing that the defendant had used a twisted coathanger to flail himself on the shoulders and down his back, producing pronounced *116red welts so severe as to have the appearance of cuts. The coathanger was introduced into evidence, as was a picture of the defendant’s wounds with the coathanger superimposed over one of the welts. While this photograph tends to establish that the wounds were inflicted with the coathanger, it sheds little or no light on the question of who inflicted the wounds. Indeed, although it appears possible that one might be able to hit oneself on the back with the coathanger in question, the very inflexibility of that object would likewise appear to preclude the infliction of wounds as severe and extensive as those depicted in photographs introduced by the State.
Nevertheless, the jury accepted the State’s theory and returned a guilty verdict. A review of the evidence suggests to us that the State’s circumstantial case probably was not sufficiently strong or cogent enough to rebut every reasonable theory other than the defendant’s guilt, which is, of course, the applicable jury standard in a prosecution based solely on circumstantial evidence. But this court does not sit as a jury on appeal, and we must measure the evidence by a different standard, i. e. whether the proof preponderates against the verdict and in favor of the defendant’s innocence. State v. Brown, 551 S.W.2d 329 (Tenn.1977). Measuring the proof against that standard, we are unable to hold that the judgment must be reversed on the insufficiency of the evidence alone.
However, we are concerned that the jury was influenced in reaching its verdict by certain other errors at trial, and given the relative weakness of the State’s case, we are unable to say that these errors did not affect the outcome of the trial. The most serious error involved a comment by the prosecutor on the fact that the defendant did not testify in his own defense.
During the opening segment of the State’s closing argument, the following colloquy occurred:
General Kidd: Also, that anything referring to the defendant’s statement would be the defendant’s statement, of course, that he gave our law enforcement officers here, at that time. And of course, not referring to his failure to testify. Then, or not testifying_ (Interrupted)
Mr. Cobb: Please the Court, we except to that statement, and move for a mistrial.
General Kidd: Certainly, anything I say -(Interrupted)
The Court: One moment, please! Ladies and gentlemen of the Jury: Ignore the statement just made by the District Attorney General. It was an improper statement. He should have known better! No reference at all can be made to the failure of the defendant to testify. He has the Constitutional Right not to testify. It’s his decision to make. The burden of proving the guilt of the defendant remains upon the State beyond a reasonable doubt. Alright. Proceed. Mr. Kidd.
General Kidd: We thank, Your Honor, for that.
The Court: Right.
General Kidd: And anything referring to a statement of the defendant is certainly to the one given to the law enforcement officers, and that alone. Because we certainly do not want to violate any Constitutional Rights, or any Rights of the defendant.
The impropriety of any comment upon a defendant’s exercise of the Fifth Amendment right not to testify is so well settled as to require little discussion. The United States Supreme Court dealt with the question in Griffin v. California, 380 U.S. 609, 85 S.Ct. 1229, 14 L.Ed.2d 106 (1965); Tehan v. United States ex rel. Shott, 382 U.S. 406, 86 S.Ct. 459, 15 L.Ed.2d 453 (1966); O’Connor v. Ohio, 385 U.S. 92, 87 S.Ct. 253,17 L.Ed.2d 189 (1966); Chapman v. California, 386 U.S. 18, 87 S.Ct. 824, 17 L.Ed.2d 705 (1967); Anderson v. Nelson, 390 U.S. 523, 88 S.Ct. 1133, 20 L.Ed.2d 81 (1968), and Fontaine v. California, 390 U.S. 593, 88 S.Ct. 1229, 20 L.Ed.2d 154 (1968). Furthermore, Tennessee law provides that the “failure of the party defendant ... to testify in his *117own behalf, shall not create any presumption against him.” T.C.A. § 40-2403. See also Tenn.Const., Article 1, Section 9. Our Supreme Court has said many times that adverse comment or argument based upon a defendant’s failure to testify may be reversible error. Smithson v. State, 127 Tenn. 357, 155 S.W. 133 (1913); Staples v. State, 89 Tenn. 231, 14 S.W. 603 (1890). See also Huckaby v. State, 3 Tenn.Cr. 84, 457 S.W.2d 872 (1970); McCracken v. State, 489 S.W.2d 48 (1972). The rule is clear, and, as the trial judge in this case noted, the comment was “improper” and the prosecutor “should have known better.”1
In Morris v. State, 537 S.W.2d 721 (Tenn.Crim.App.1976), this court dealt with a situation very similar to the one now before us. There the prosecutor told the jury, “. . . I’m not commenting on the fact that the defendant didn’t take the stand, because that is his God-given right . ..” 537 S.W.2d at 723. In holding that this statement resulted in reversible error, the Morris court noted that “[sjometimes it is more effective to get across a message in a negative manner” and held that “in the very telling the jury that he was not commenting on the fact the defendant didn’t take the stand, the prosecuting attorney most emphatically was making such comment.” 537 S.W.2d at 723.
Having determined that the initial comment constituted error, it next becomes our task to decide whether the cautionary instructions given by the trial judge were sufficient to cure the error so thoroughly as to render it harmless beyond a reasonable doubt. For it was in Chapman v. United States, supra, in the context of a violation of the very Fifth Amendment right involved here, that the United States Supreme Court laid down its rule for determining whether or not constitutional error may be considered harmless in a given case. There the adverse comment by the prosecuting attorney on the defendant’s failure to testify was held not to be harmless. According to the Chapman court, “before a federal constitutional error can be held harmless, the court must be able to declare a belief that it was harmless beyond a reasonable doubt.” 386 U.S. at 24, 87 S.Ct. at 828.
Reviewing this record, we do not believe that the standard announced in Chapman has been met. We are especially concerned because, taking the improper comment in context, there appears to be absolutely no justification for the prosecution to have done anything more than to identify the statement in question as the one given to police by the defendant. It was totally unnecessary to go farther and attempt to distinguish from a non-existent statement at trial. We believe the attempt to do so makes untenable any “good faith” argument on behalf of the prosecutor.
We note also several other disturbing aspects of the prosecution’s argument. In its closing segment, the State propounded to the jury what we consider to be a prejudicially erroneous explanation of the reasonable doubt standard, saying, in effect, that if the jury “knows” the defendant is guilty, but concludes that the State has failed to prove its case, the jury must nevertheless convict the defendant because the State has actually proved its case — otherwise the jury could not “know” the defendant was guilty. The Assistant District Attorney then closed his final argument by calling on the jury to convict the defendant so that “. . . Leonard Ledford won’t be walking the streets like [his brother] Carl.” To imply to the jury that they should convict one person in order to make up for what the State considered to be a *118wrongful acquittal of another person is, of course, so reprehensible and inflammatory that the prejudicial effect of such an argument can hardly be calculated.
We are doubly concerned with the inflammatory and prejudicial argument in this case because of the wholly circumstantial and rather insubstantial nature of the proof of guilt against the defendant. As we said in Judge v. State, 539 S.W.2d 340, 346:
While the evidence here preponderates in the State’s favor on appeal, this case was a very “close” one at trial when viewed by the reasonable doubt standard. Therefore, the prejudicial impact of the statement on the jury is likely to have been greater than it would have been had evidence of the defendant’s guilt been overwhelming, (citations omitted).
Finally, in determining that the improper argument in this case cannot be viewed as harmless beyond a reasonable doubt, we note also that there is another error in this record which may have had a cumulative effect on the jury’s verdict. In ruling on the admissibility of the defendant’s hospital records, the trial court deleted several entries at the State’s request, apparently on the ground that they called for an opinion which the recording nurse and physician were not qualified to give. Among these notations were the following entries: “badly beaten [by what app’rs 2½ " belting c metal tipping:’ “voided [urine] involuntarily”; “states fainted at funeral home”; “due to attack”; “apparently beaten.”
We recognize the discretion of the trial judge to exclude from hospital record “any portions which are objectionable.” Graham v. State, 547 S.W.2d 531, 538 (Tenn.1977). But under the Graham decision the “qualifications of the individual preparing the record may be inquired into, may be challenged, or may be disputed but this goes to weight and not to admissibility.” 547 S.W.2d at 538. We think it is clear that most of the excluded entries should have been presented to the jury, for whatever probative value they may have had.2 The one exception is the notation “States fainted [at] funeral home,” which on its face constitutes double hearsay and, therefore, must satisfy some exception to the hearsay rule beyond the business records exception in order to be admissible. E. Cleary, McCormick on Evidence, § 313 (2d ed. 1972).
We thus conclude that the assignments of error related to the prosecutor’s improper argument and the admissibility of the hospital records must be sustained. We are of the further opinion that the error involved was such as to deprive the defendant of a fair trial, and that the case must be remanded for retrial.
The defendant’s two remaining assignments of error require only brief mention. The trial court did not err in admitting the photograph of the defendant’s body with the twisted coathanger, later introduced into evidence, superimposed over one of the wounds. The photograph was relevant and not inflammatory, and it was therefore admissible. Furthermore, the trial court’s instruction on the law of tenancy by the entirety, while somewhat unique in a criminal trial, was not erroneous per se and covered a legal issue which had been raised by both parties to the lawsuit. However, if a similar instruction is given upon retrial, we suggest that it be carefully worded so as to avoid any possible implication that it constitutes a comment on the evidence by the trial judge.
The judgment of the trial court is reversed and the case is remanded for further proceedings not inconsistent with this opinion.
DWYER, P. J., and RUSSELL, J., concur.. Not only was the remark wholly improper, but the severity of its potentially prejudicial effect was increased by the fact that it was couched in terms of the defendant’s failure to testify rather than his right not to take the ' stand. The word “failure” may well have conveyed to the jury the feeling that the defendant was somehow shunning an obligation, morally, if not legally, to take the stand and explain away certain circumstances pointing to his guilt. Unfortunately, the cautionary instruction given to the jury at that time reemphasized this approach, as did the final charge to the jury, wherein the trial judge again spoke of the defendant’s “failure” to testify.
. This is particularly true since it appears that the redacted exhibit as it went to the jury included several entries based on opinion of the same nature as those excluded, and thus were equally objectionable. It further appears that only the ones helpful to the defendant were excluded, a process which may well have violated the defendant’s right to a fair hearing. Cf. Chambers v. Mississippi, 410 U.S. 284, 93 S.Ct. 1038, 35 L.Ed.2d 297 (1973).
