delivered the opinion of the Court.
The prosecuting attorney filed informations against appellant Juan García Garcia charging him with the offenses of Murder in the First Degree and Violation of §§ 6 and 8 of the Weapons Law, by reason of having killed the human being Pedro Abraham Solivan by firing several revolver shots at him.
On December 7, 1965, the cases were called for trial. While the jury was being drawn and before the latter was finally sworn (Rule 125 of the Rules of Criminal Procedure) the prosecuting attorney requested leave of court to amend *810the information of murder for the purpose of including an allegation in relation to defendant’s former conviction of an offense of Assault to Commit Murder.
With the objection of the defense the court allowed the amendment and granted five days to the prosecuting attorney to file the amended information, excused the jury, and ordered the setting of the date for the reading of the amended information.1
After the subsequent proceedings as a result thereof the three cases were heard jointly, that of Murder and that of violation of § 8 of the Weapons Law before the jury, and that of violation of § 6 of said Weapons Law by the court.
The jury found defendant guilty of Murder in the Second Degree2 and guilty of the violation of § 8 of the Weapons Law. The court also found him guilty of the violation of § 6 of the Weapons Law.3
*811Defendant appealed from the judgments rendered against him and in his brief he assigns the commission of four errors; the first of which is set forth as follows:
“First Error: The Superior Court erred in passing on the case of murder as well as on the case of violation of § 8 of the Weapons Law under certain informations which had not been ordered, after the dismissal of the original informations.”
In support of this contention appellant cites our decision in the case of García v. District Court, 68 P.R.R. 20 (1948), where we said, ratifying People v. González, 39 P.R.R. 343 (1929), that leave to file a new information is not an order to do so, and that the judge should have followed the language of the statute and ordered the information to be filed, and in failing to do so, he committed error in overruling the motion to dismiss the informations on that ground.
This case law cannot be invoked as the basis for a decision favoring the contention raised by appellant. In said cases § § 157 and 158 of the Code of Criminal Procedure included in Chapter III of said Code entitled “Demurrer” were construed. According to § 157, if the court allowed a demurrer to the information, “the judgment is final upon the information demurred to, and is a bar to another prosecution for the same offense, unless the court, being (is) of the opinion that the *812objection on which the demurrer is allowed may be avoided in a new information, and directs a new information to be filed; . . .” Pursuant to § 158 if “the court does not permit the information to be amended, nor direct that an information be filed, the defendant, if in custody, must be discharged,...”
Rule 62 of the Rules of Criminal Procedure abolished the demurrer and substituted it with the motion to dismiss and Rule 64 specifies the grounds on which said motion may be based.
In the instant case the original informations were not dismissed by virtue of having filed against them the ancient demurrer or a motion to dismiss. The prosecuting attorney requested leave to amend the information for the purpose of adding the allegation of subsequent offense which had been omitted. Rule 38 (b) of the Rules of Criminal Procedure authorizes the court to allow, at any time before the conviction or acquittal of defendant, the necessary amendments to cure any substantial defect or omission in the information.4 Considering that the allegation of former conviction was one of substantial nature,5 the court ordered a new arraignment.
The order of the court referred to in García v. District Court, supra, was not necessary. It sufficed that the court allow, as it did in this case, the amendments to the informa-tions.
*813In his second assignment appellant maintains that the trial court committed error in failing to order the discharge of the jury for the prosecuting attorney having asserted, rather than asked defendant’s wife, that the latter had been accused of mayhem and convicted of aggravated assault and battery.
It is true that while the prosecuting attorney cross-examined defendant’s wife, witness for the defense, in asking her a question the former asserted that in the year 1965 defendant had been charged with an offense of mayhem having béen found guilty of the lesser offense of aggravated assault and battery.
Assuming that the prosecuting attorney erred in presenting to the jury a fact on which there was no evidence, there appears from the record that, subsequently, the prosecuting attorney offered, and it was admitted in evidence, a certified copy of the judgment rendered against defendant in the case of mayhem, to which the prosecuting attorney had referred when he cross-examined the former’s wife. If the error was committed, it was cured and it cannot be maintained that appellant’s substantial rights were prejudiced.
The third error assigned is that the court permitted passing to the jury sworn statements and certifications of judgments rendered against appellant.
The documents specifically indicated are the partial transcript of the testimony offered by defendant’s wife in another prosecution against appellant held in the year 1965, a judgment, and a complaint.
The jury did not take with it any confession or testimony of defendant containing incriminatory admissions. See People v. Vega Román, 92 P.R.R. 658 (1965), invoked by appellant. Rule 140 of the Rules of Criminal Procedure forbids that the jury, upon retiring for deliberation, take with *814them the depositions.6 Assuming that the partial transcript of the testimony of defendant’s wife given before in another prosecution should fall under the prohibition of Rule 140, and should it constitute error, the same would not give rise to the reversal of the judgments appealed from.
In the prosecuting attorney’s cross-examination, said witness had testified that that was the first time she came to court and that she did not know of other cases in which her husband might have been involved. The transcript was presented to show that she had appeared in court before and that she had been a witness in another case prosecuted against her husband. The transcript, which was admitted in evidence and which passed to the jury, is brief. The witness merely testified that she knew defendant, who is her husband now, that she knew Catalina López, who is her sister and Rogelio Alvino’s wife, who were separated at that time; that on July 22, 1964 she saw her sister and that they lived together in the same house in ward Beatriz in Cayey. That is all the content of said transcript. Therefore, we consider that the fact that the jury did take with them said transcript, upon retiring for deliberation, did not prejudice defendant-appellant’s substantial rights.
The fourth and last error assigns that the court admitted evidence of the former conviction alleged in the informa-tions, despite the fact that defendant had accepted it previously, and invokes the cases of People v. Aponte, 83 P.R.R. 491 (1961) and People v. Hernández Pérez, 94. P.R.R. 588 (1967).
Pursuant to the provisions of Rule 68 of the Rules of Criminal Procedure and to our decisions, when defendant admits at the proper time the allegation of former conviction, the latter shall not be informed to the jury in any manner whatsoever. We have said that defendant may be tried only *815for the offense charged and that evidence of other offenses committed by him is not admissible except when the former offense is one within the exceptions established in our case law. '
In this case, while the prosecuting attorney presented evidence on the former conviction alleged in the informations which was admitted and passed to the jury, evidence of other offenses previously committed by defendant was also admitted.7 From said evidence there appear a conviction of assault to commit homicide and several convictions of the offenses of aggravated assault and battery and assault and battery. All this evidence was admitted under the doctrine in People v. Cruz, 65 P.R.R. 160 (1945), to the effect that defendant may present evidence of specific acts of violence committed by the victim when the former has alleged self-defense and there is conflict as to (1) which of the two, defendant or the victim, was the aggressor and (2) where the defendant seeks to prove that he had reasons to believe, upon being attacked by the victim, that he was confronting a dangerous enemy; but where defendant seeks to prove blood-shedding offenses committed by the victim, the People may present evidence to prove defendant’s convictions for the same offense.
In view of the attendant circumstances, the fact that evidence on the former conviction alleged in the informa-tions passed to the jury did not prejudice defendant’s substantial rights nor does said fact justify the reversal of the judgments appealed from.
Said judgments will be affirmed.
