Defendant has brought forward thirteen (13) of thirty-four (34) assignments of error in his brief, the others having been abandoned. Rule 28, Rules of Practice in the Supreme Court. Investment Properties v. Allen, 281 N.C. 174, 188 S.E. 2d 441 (1972); Knutton v. Cofield, 273 N.C. 355, 160 S.E. 2d 29 (1968); Pendergrass v. Massengill, 269 N.C. 364, 152 S.E. 2d 657 (1967).
*153Defendant contends in his first series of assignments (Nos. 25, 30 and 33) that the trial court erred in charging the jury as to the type of provocation that could mitigate the killing to voluntary manslaughter. Specifically, defendant excepted and assigned error to the following italicized portions of the court’s charge:
(1) After summarizing the evidence, and prior to fully instructing on first-degree murder, the court stated: “ [L] et me say here, that mere words will not form a justification or excuse for a crime of this sort. ...”
(2) In instructing the jury on voluntary manslaughter, the court stated: “[T]he defendant must satisfy you that this passion was produced by acts of Samples which the law regards as adequate provocation. This may consist of anything which has a natural tendency to produce such passion in a person of average mind and disposition. However, words and gestures alone, where no assault is made or threatened, regardless of how insulting or inflammatory those words or gestures may be, does not constitute adequate provocation for the taking of a hrnnan life; . .
Defendant brings forward two distinct, yet closely related, arguments in support of these assignments. We shall proceed to consider these contentions in the order set forth in defendant’s brief.
A. Mere Words as Sufficient Legal Provocation.
[1] Defendant concedes that the above italicized portions of the court’s charge represent a correct statement of the common law, accepted and recognized as the law of this State from the first reported cases. See, e.g., State v. Tackett, 8 N.C. 210, 219 (1820); State v. Merrill, 13 N.C. 269 (1829) ; State v. Hill, 20 N.C. 629, 635 (1839) ; State v. Jarrott, 23 N.C. 76, 82 (1840) ; State v. Barfield, 30 N.C. 344, 349 (1848) ; State v. Howell, 31 N.C. 485 (1849). See also 7 Encyclopedic Digest of N. C. Reports, Homicide § 39 (1918). Defendant further concedes that this rule is almost uniformly recognized throughout the United States. See, e.g., Annot., 2 A.L.R. 3d 1292 (1965) ; 40 Am. Jur. 2d Homicide § 64 (1968) ; 40 C.J.S. Homicide § 47 (1944). Nonetheless, defendant contends that the doctrine in "this State has gradually evolved into a per se rule that is not in accord with early judicial pronouncements of this Court. Therefore, he urges *154us to modify the present rule. In support of this contention, defendant relies heavily on language contained in the following three cases: State v. Norris, 2 N.C. 429 (1796) ; State v. Tackett, supra; and State v. Jarrott, supra.
Initially, we point out that State v. Norris, supra, is not an opinion of this Court. It is simply a summarized report of the actual trial of defendant over which Judges Williams and Haywood jointly presided as circuit superior court judges. There were only four such judges in this State at that time and further there was no appellate court. See Clark, C.J., History of the Supreme Court of North Carolina, 177 N.C. 617, 619 (1919). The language defendant cities in his brief as the opinion of the Court is merely Judge Haywood’s charge to the jury. We note that in his separate charge, Judge Williams told the jurors that he disagreed with certain portions of the law as previously stated by Judge Haywood and proceeded to instruct in accord with his own views. Accordingly, under these particular facts, this reported proceeding has no precedential value.
On the other hand, both Tackett and Jarrott are decisions of this Court and both contain language that tends to support defendant’s contention. However, the exceptions to the “mere words” doctrine recognized in both- cases are totally without relevance today. In any event, any language in these cases not in accord with the following statement of Justice Stacy (later Chief Justice), speaking for the Court in State v. Benson, 183 N.C. 795, 799, 111 S.E. 869, 871 (1922), is expressly overruled. “The legal provocation which will reduce murder in the second degree to manslaughter must.be more than words; as language, however abusive, neither excuses nor mitigates the killing, and the law does not recognize circumstances as a legal provocation which in themselves do not amount to an actual or threatened assault. [Citations omitted.]” This assignment of error as it relates to the mere words doctrine is overruled.
B. What Constitutes an Assault?
[2] Defendant contends that since the trial court inserted the “mere words” doctrine into its charge it constituted prejudicial error not to proceed further and charge on what he calls the law of assault from provoking language. Defendant relies on the following cases in support of this argument: State v. Perry, 50 N.C. 9 (1857) ; State v. Robbins, 78 N.C. 431 (1878) ; State v. Chavis, 80 N.C. 353 (1879) ; State v. King, 86 N.C. 603 *155(1882); State v. Fanning, 94 N.C. 940 (1886) ; Saunders v. Gilbert, 156 N.C. 463, 72 S.E. 610 (1911); State v. Kennedy, 169 N.C. 326, 85 S.E. 42 (1915) ; State v. Crisp, 170 N.C. 785, 87 S.E. 511 (1916); State v. Baldwin, 184 N.C. 789, 114 S.E. 837 (1922); State v. Strickland, 192 N.C. 253, 134 S.E. 850 (1926) ; State v. Maney, 194 N.C. 34, 138 S.E. 441 (1927) ; State v. Robinson, 213 N.C. 273, 195 S.E. 824 (1938) ; State v. Hightower, 226 N.C. 62, 36 S.E. 2d 649 (1946) ; State v. Franklin, 229 N.C. 336, 49 S.E. 2d 621 (1948); State v. McLawhorn, 270 N.C. 622, 155 S.E. 2d 198 (1967). This contention has no merit. Furthermore, it is logically inconsistent with the rule that language, no matter how abusive, is never sufficient legal provocation to mitigate a homicide.
Many of the above cited cases involve the defendant’s right to the benefit of perfect self-defense and deal specifically with the question of whether the defendant was at fault in bringing on the difficulty. The test, long employed in such cases, is whether the defendant used language calculated and intended to bring on the fight. If he did, then he is deemed to have been at fault and loses the benefit of perfect self-defense. See. e.g., State v. Robinson, supra; State v. Crisp, supra; State v. Lancaster, 169 N.C. 284, 84 S.E. 529 (1915) ; State v. Rowe, 155 N.C. 436, 71 S.E. 332 (1911) ; State v. Fanning, supra; State v. Davis, 80 N.C. 351 (1879); State v. Robbins, supra; State v. Perry, supra.
State v. Hightower, supra, is an excellent example of the legal consequences of abusive language in this situation. In that case, defendant and deceased were both inmates confined in a prison camp located in Wilkes County. Sometime prior to the homicide, defendant had been placed in solitary confinement for a number of days. Defendant believed this confinement resulted from a report deceased had made to prison officials regarding alleged acts of sex perversion on his part. On the day of the killing, defendant came out into the prison yard where the deceased and others were passing a ball. He put his arm around the deceased and walked with him back into the cell block. Thereafter, defendant tripped and stabbed the deceased, and when, before dying, the deceased managed to get up and run to the sink, defendant caught up with him and stabbed him five or six more times, stating: “G— d— you, I told you I was going to kill you.” Defendant contended that deceased had called him a “G— d— black s.o.b.” and that this had provoked the assault. *156Defendant was tried before Judge Bobbitt (later Associate Justice and Chief Justice of this Court) at the August 1945 Session of Wilkes County Superior Court. Upon a verdict finding him guilty of first-degree murder, defendant appealed to this Court and assigned as errors, inter alia, the portion of the court’s charge on the “mere words” doctrine and the failure of the court to charge on excusable homicide. This Court, in an opinion by Justice Barnhill (later Chief Justice), affirmed the judgment and answered these contentions as follows:
“The court further instructed the jury ‘that legal provocation that will reduce murder in the second degree to manslaughter must be more than mere words, for language, however abusive, neither excuses nor mitigates the killing,’ and ‘the law does not recognize circumstances as a legal provocation which in themselves do not amount to an assault or a threatened assault.’ Such is the law in this jurisdiction. [Citations omitted.] Here it was the deceased and not the defendant who is alleged to have used abusive language and thus induced the assault which resulted in death. S. v. Robinson, 213 N.C., 273, 195 S.E., 824; S. v. Rowe, 155 N.C., 436, 71 S.E., 332; S. v. Crisp, 170 N.C., 785, 87 S.E., 511.” 226 N.C. at 65, 36 S.E. 2d at 651. (Emphasis supplied.)
These decisions establish the following rules as to the legal effect of abusive language: (1) Mere words, however abusive, are never sufficient legal provocation to mitigate a homicide to a lesser degree; and (2) A defendant, prosecuted for a homicide in a difficulty that he has provoked by the use of language “calculated and intended” to bring on the encounter, cannot maintain the position of perfect self-defense unless, at a time prior to the killing, he withdrew from the encounter within the meaning of the law. These two rules are logically consistent and demonstrate that abusive language will not serve as a legally sufficient provocation for a homicide in this State.
These well-settled rules are clearly controlling in the instant case. Hence, if defendant had provoked an assault by the deceased through the use of abusive language and had thereafter killed the deceased, then it would have been for the jury to determine if the lanuguage used by defendant, given the relationship of the parties, the circumstances surrounding the verbal assertions, etc., was “calculated and intended” to bring on the assault. If the jury had found this to be the case, then defend*157ant would not have had the benefit of the doctrine of perfect self-defense, even though the deceased instigated the actual physical attack. But, here there was no evidence that defendant killed the deceased in self-defense. In fact, all of the evidence tends to show that the fatal attack was brought on by the continued verbal abuses directed toward defendant by the deceased. Under these circumstances, there was no basis for a jury determination of whether any of the words were “calculated and intended” to bring on the difficulty. Therefore, we find no error in the court’s instructions or in the court’s failure to give instructions. These assignments are overruled.
At this point, we note that in those few jurisdictions that permit abusive language to mitigate the degree of homicide, the majority hold that the words are only deemed sufficient to negate premeditation, thereby reducing the degree of homicide from first to second. Most of these courts reason that since the deceased had made no attempt to endanger the life of the accused, the action of the latter in meeting the insulting remarks with sufficient force (deadly or otherwise) to cause the death of the former, was beyond the bounds of sufficient retaliation to constitute sufficient provocation to reduce the homicide to manslaughter. See Annot., 2 A.L.R. 3d 1292, 1308-10 (1965). Although we expressly decline to adopt this minority view, we note that the jury in the instant case apparently applied the same reasoning and found defendant guilty of second-degree murder. Thus, even if the minority rule applied in this State, defendant would not be entitled to a new trial as a result of the instructions here given.
[3] Defendant next contends (Assignment No. 29) that the trial court committed prejudicial error in charging the jury as follows:
“Now, ladies and gentlemen of the jury, this case is to be tried by you under the laws of the State of North Carolina, and not upon the rules and regulations and customs and unwritten code that exists within the walls of the North Carolina Department of Correction. I can’t charge you on that law because I don’t know that law. I think I know this one, and this is the law that you are trying this case under.”
Defendant argues that this instruction “tends to discount as a matter of law all of the factual information” that the jury *158was “entitled to consider, not as a law, but as a part of the factual background situation within which the incident took place.” We find nothing in the charge to support such an inference. During the course of the trial, several of the State’s witnesses (either present or former prison inmates) testified about a “prison code,” i.e., a set of unwritten rules developed by the prisoners themselves. For example, one of the State’s witnesses made the following statements on cross-examination:
“In the prison system, if Watson had not fought after Samples had called him nigger, nigger, and talked about his mother, I guess, you know, everybody else probably would be jugging at him. What I mean by ‘jugging at him,’ I mean, messing with him, you know. Taking advantage of the fact that he won’t stand up for himself. It is important that you stand up for yourself in the system because if you don’t, somebody might get you down in the shower, you know. You might get dead-ended. It means if you don’t take up for yourself, everybody picks on you.”
Apparently, standing up for oneself was a vital part of this so-called “prison code.” In this context, the import of the above instruction was clearly to inform the jurors that the case— like ¿11 other criminal cases tried in the North Carolina General Courts of Justice — had to be tried under the laws of this State and not upon any unwritten prisoners’ code that existed within the walls of North Carolina’s prisons. It is certainly not error for a trial judge to so instruct a jury. Furthermore, it appears that defendant’s conduct even constituted a violation of the prisoners’ code. We refer to the following re-direct testimony of the same witness previously quoted above: “Stand up for yourself in the prison system would not necessarily include using a knife. He could have run over there and fought with bare fists, that would have been standing up for himself
Defendant’s contention under this assignment is without merit. Therefore, it is overruled.
[4] Defendant next assigns error (No. 32) to that portion of the trial court’s charge on the element of first-degree murder that requires a defendant to act with deliberation. Specifically, defendant excepted to the following portion of the court’s charge :
“A cool state of blood does not mean the absence of passion or emotion, but it means that notwithstanding that *159anger or emotional state, unless the emotion was such at the time to disturb the defendant’s faculties and reason to the extent that he could not form a deliberate purpose and control his actions.”
Defendant argues that the above language tends “to make the instruction one in which the Defendant is required to be ‘temporarily deprived of intellect, and therefore not an accountable agent,’ rather than swayed by passion.” In substance, it appears that defendant’s objection is directed to the meaning of “deliberation” as that term applies to first-degree murder. In State v. Benson, supra, in an opinion by Justice Stacy (later Chief Justice), this Court defined deliberation as follows:
“Deliberation means that the act is done in a cool state of the blood. It does not mean brooding over it or reflecting upon it for a week, a day, or an hour, or any other appreciable length of time, but it means an intention to kill, executed by the defendant in a cool state of the blood, in furtherance of a fixed design to gratify a feeling of revenge, or to accomplish some unlawful purpose, and not under the influence of a violent passion, suddenly aroused by some lawful or just cause or legal provocation.” 183 N.C. at 798, 111 S.E. at 871.
Accord, State v. Johnson, supra; State v. Reams, 277 N.C. 391, 178 S.E. 2d 65 (1970), cert. denied, 404 U.S. 840 (1971) ; State v. Lamm, 232 N.C. 402, 61 S.E. 2d 188 (1950) ; State v. Steele, 190 N.C. 506, 130 S.E. 308 (1925).
This Court has also defined “cool state of blood” as follows:
“ ‘Cool state of blood’ does not mean the absence of passion and emotion, but an unlawful killing is deliberate and premeditated if done pursuant to a fixed design to kill, notwithstanding that defendant was angry or in an emotional state at the time unless such anger or emotion was such as to disturb the faculties and reason. [Citations omitted.]” State v. Britt, 285 N.C. 256, 262-63, 204 S.E. 2d 817, 822 (1974).
Although the Benson and Britt instructions are preferred, we find no fundamental difference between them and the instruction given in the instant case. In any event, since defendant was convicted of murder in the second degree, it is clear that any error in the judge’s charge concerning the elements of first-*160degree murder is harmless. See, e.g., State v. Artis, 233 N.C. 348, 64 S.E. 2d 183 (1951) ; State v. Suddreth, 230 N.C. 239, 52 S.E. 2d 924 (1949) ; State v. Cade, 215 N.C. 393, 2 S.E. 2d 7 (1939) ; State v. Evans, 177 N.C. 564, 98 S.E. 788 (1919). This assignment is accordingly overruled.
[5] In his next series of assignments (Nos. 5, 6, 7 and 8) defendant contends that the court erred in allowing, over his objection, testimony as to defendant’s possession of a kitchen paring knife in violation of the rules of Polk Youth Center. This evidence was brought out by the district attorney during the redirect examination of two of the State’s witnesses. Defendant argues that this evidence “comes within the prohibition against collateral circumstantial evidence to show the guilt of the defendant as to a particular crime,” and that, in any event, the evidence was irrelevant and its admission was highly prejudicial. We disagree.
“Evidence of other offenses is inadmissible on the issue of guilt if its only relevancy is to show the character of the accused or his disposition to commit an offense of the nature of the one charged; but if it tends to prove any other relevant fact it will not be excluded merely because it also shows him to have been guilty of an independent crime.” 1 Stansbury, N. C. Evidence § 91 (Brandis Rev. 1973) (Emphasis supplied.) Accord, State v. Jones, 278 N.C. 88, 178 S.E. 2d 820 (1971) ; State v. Williams, 275 N.C. 77, 165 S.E. 2d 481 (1969) ; State v. Norkett, 269 N.C. 679, 153 S.E. 2d 362 (1967) ; State v. Choate, 228 N.C. 491, 46 S.E. 2d 476 (1948).
In State v. McClain, 240 N.C. 171, 81 S.E. 2d 364 (1954), this Court, in an opinion by Justice Ervin, listed eight exceptions to the general rule of exclusion of evidence of a crime other than the one charged. This testimony clearly falls within the purview of Exception No. 2, i.e., a collateral act of the accused that tends to establish a specific intent or mental state that is an element of the crime charged. Certainly defendant’s possession of the knife in contravention of well-known prison rules was admissible as circumstantial evidence of a planned killing. The “acid test” here is the logical relevance of this testimony to the first-degree murder prosecution. See State v. McClain, supra at 177, 81 S.E. 2d at 368. We believe this test has been met. See generally E. Cleary, McCormick on Evidence § 185 (1972). Even assuming, arguendo, that the admission of *161this testimony was error, the error was clearly harmless. “Where there is abundant evidence to support the main contentions of the State, the admission of evidence, even though technically incompetent, will not be held prejudicial when defendant does not affirmatively make it appear that he was prejudiced thereby or that the admission of the evidence could have affected the result. [Citations omitted.]” State v. Williams, supra at 89, 165 S.E. 2d at 489. Accord, Gasque v. State, 271 N.C. 323, 340, 156 S.E. 2d 740, 752 (1967) ; State v. Temple, 269 N.C. 57, 66, 152 S.E. 2d 206, 212 (1967). These assignments are therefore without substance and hence without merit. They are overruled.
[6] Defendant next contends (Assignment No. 4) that the trial court committed prejudicial error in allowing the State’s motion to strike certain testimony and in instructing the jury to disregard that testimony.
The following occurred on re-cross examination of the State’s witness Wandzillak:
“I had the impression that Samples had thought Watson was scared when he was lying on top of his bunk on his back. In crossing the corridor it was not a casual walk but a rush.
“Q. How would you describe it?
“A. Spirit of the moment.
“Mr. Mitchell: Objection, motion to strike.
“Court: Allowed. You may disregard that answer of the witness.”
Defendant argues that the above statement was admissible as either a shorthand statement of the facts, or as lay testimony on the mental capacity and condition of the defendant. We agree. Opinion evidence is always admissible when the facts on which the opinion or conclusion is based cannot be so described that the jury will understand them sufficiently to be able to draw their own inferences. See 1 Stansbury, N. C. Evidence § 125 (Brandis Rev. 1973), and numerous cases cited therein. However, any error there may have been in sustaining the objection and motion to strike is not deemed sufficiently prejudicial to justify the award of a new trial. Cf. State v. Gray, 268 N.C. 69, 84, 150 S.E. 2d 1, 12 (1966).
*162 [7] In his next two assignments (Nos. 9 and 28) defendant contends that the trial court erred in charging the jury in violation of G.S. 1-180 by an imperfect or an incorrect summation of the evidence. Specifically, defendant excepted to the following italicized portions of the charge:
“That shortly prior to that time Mr. Watson and Mr. Samples had been first talking and later arguing, as I recall the evidence, sitting on Mr. Watson’s bunk; that Mr. Samples left Mr. Watson’s bunk and went to his bunk procuring a cigarette from another inmate on the way and lay on his bunk smoking the cigarette up to <md after the time when the lights went off; that at some period of time, variously testified as between four and ten minutes after Mr. Samples left the immediate presence of Mr. Watson and after the lights had been dimmed, Mr. Watson left his bunk, went over to Mr. Samples’ bunk and was seen to strike anywhere from eight to ten blows with his fist clinched as if it were a hammer, toward the chest area of Mr. Samples;...”
Defendant contends that the above charge contains two errors, to wit: (1) it implies that Samples had in fact withdrawn from the controversy and retired for the evening; and (2) it misstated the time interval between Samples’ departure from defendant’s bunk and defendant’s subsequent attack upon Samples. These contentions have no merit. Our reading of the charge reveals no implication that the deceased, Samples, had “withdrawn from the controversy and retired for the evening.” The judge was merely summarizing the evidence as he is required to do. G.S. 1-180. As to the second alleged error, it is conceded that the court may have misstated the time element as the evidence tended to show a two-to-ten minute interval as opposed to a four-to-ten. However, the record does not disclose that this error in the court’s review of the evidence was brought to the attention of the court so that it could have been corrected. Generally, an inadvertence in recapitulating the evidence must be called to the trial court’s attention in time for correction and will not be held reversible error when this is not done. See, e.g., State v. Lampkins, 286 N.C. 497, 506, 212 S.E. 2d 106, 111 (1975) ; State v. Goines, 273 N.C. 509, 160 S.E. 2d 469 (1968) ; State v. Feaganes, 272 N.C. 246, 158 S.E. 2d 89 (1967). See also 3 Strong, N. C. Index 2d, Criminal Law § 113 (1967). In any event, this misstatement is of little consequence since it mainly *163related to the elements of premeditation and deliberation and defendant was found not guilty of first-degree murder.
We have closely examinéd all the assignments brought forward in defendant’s brief and conclude that he has had a fair trial, free from prejudicial error.
No error.
