In 1968, the defendant was convicted, on a trial to the jury, of having heroin under his control in violation of Public Act No. 555, adopted in the 1967 session of the General Assembly. See General Statutes § 19-481. He was also found guilty of being an habitual offender under the provisions of what was then § 54-121 of the General Statutes. He appealed from the judgment assigning error in (1) the denial of his motion to suppress evidence; (2) certain rulings on the admissibility of evidence; (3) the denial of his motion for a mistrial; (4) the denial of his motion to dismiss the habitual offender part of the information; and (5) the sentence imposed.
At the hearing on his pretrial motion to suppress and on this appeal, the defendant has claimed that the affidavit in support of the application for a warrant to search an apartment at 584 Berkshire Avenue in Bridgeport, prepared by the police and submitted to a judge of the Circuit Court (Eielson, J.) on December 28, 1967, did not support a finding of probable cause to believe that evidence of criminal activity existed within the apartment alleged by the affiants to be premises where such *626evidence was concealed. The defendant asserts that the judge acted improperly in issuing the search warrant, and that under the provisions of the fourth amendment to the constitution of the United States as applied to the states by the fourteenth amendment, his motion to suppress should have been granted and the items seized in that apartment pursuant to the authority of the warrant should not have been admitted in evidence.
Specifically, the defendant contends that the affidavit supporting the application for the search warrant does not contain any facts which connect the asserted illegal activity with the apartment sought to be searched. The application for the warrant was predicated upon information supplied to the police by two informants whom they represented to be reliable. In the first two paragraphs of the affidavit and application for the warrant the apartment to be searched and in which it was complained that narcotic drugs and paraphernalia were located was specifically described as “[a] 3 story dwelling, with grey imitation brick siding, the 1st floor apartment on the right side front numbered 584 Berkshire Ave., Bridgeport, Conn.” After reciting that one of the reliable informants had stated that Bose bought heroin out of town, mixed it with sugar, packaged it in small white packets, scotch taped it, and sold it to addicts, the affidavit then described the paraphernalia used by Bose and stated: “These items are kept in a closet just right of the entrance door to the apartment.” This reference to “the apartment” is the first reference to any apartment after the specific earlier description of the apartment at 584 Berkshire Avenue, Bridgeport, for which the search warrant was sought. Clearly the premises to be searched and the illegal activity *627being conducted on those premises by Rose were sufficiently identified to support the issuance of the search warrant.
As Justice Goldberg said in United States v. Ventresca, 380 U.S. 102, 108-09, 85 S. Ct. 741, 13 L. Ed. 2d 684, referring to the historical development of constitutional standards in the area of search and seizure: “These decisions reflect the recognition that the Fourth Amendment’s commands, like all constitutional requirements, are practical and not abstract. If the teachings of the Court’s cases are to be followed and the constitutional policy served, affidavits for search warrants, such as the one involved here, must be tested and interpreted by magistrates and courts in a commonsense and realistic fashion. They are normally drafted by nonlawyers in the midst and haste of a criminal investigation. Technical requirements of elaborate specificity once exacted under common law pleadings have no proper place in this area. A grudging or negative attitude by reviewing courts toward warrants will tend to discourage police officers from submitting their evidence to a judicial officer before acting.
“This is not to say that probable cause can be made out by affidavits which are purely conclusory, stating only the affiant’s or an informer’s belief that probable cause exists without detailing any of the ‘underlying circumstances’ upon which that belief is based. See Aguilar v. Texas, . . . [378 U.S. 108, 109, 84 S. Ct. 1509, 12 L. Ed. 2d 723]. Recital of some of the underlying circumstances in the affidavit is essential if the magistrate is to perform his detached function and not serve merely as a rubber stamp for the police. However, where these circum*628stances are detailed, where reason for crediting the source of the information is given, and when a magistrate has found probable cause, the courts should not invalidate the warrant by interpreting the affidavit in a hypertechnical, rather than a commonsense, manner. Although in a particular case it may not be easy to determine when an affidavit demonstrates the existence of probable cause, the resolution of doubtful or marginal cases in this area should be largely determined by the preference to be accorded to warrants.”
This court has also had occasion to observe: “The principles by which we test the adequacy of an affidavit have been designed to insure that a disinterested judicial officer make his own comm on sense judgment that there is probable cause for the issuance of the warrant. Spinelli v. United States, 393 U.S. 410, 415, 89 S. Ct. 584, 21 L. Ed. 2d 637; Aguilar v. Texas, 378 U.S. 108, 110-11, 84 S. Ct. 1509, 12 L. Ed. 2d 723; State v. Jackson, 162 Conn. 440, 444, 294 A.2d 517.” State v. Grayton, 163 Conn. 104, 106, 302 A.2d 246, cert. denied, 409 U.S. 1045, 93 S. Ct. 542, 34 L. Ed. 2d 495; see also State v. Saidel, 159 Conn. 96, 98, 267 A.2d 449.
Keeping in mind the fact that the reviewing court may consider only information brought to the issuing judge’s attention; Aguilar v. Texas, 378 U.S. 108, 109, 84 S. Ct. 1509, 12 L. Ed. 2d 723; Giordenello v. United States, 357 U.S. 480, 486, 78 S. Ct. 1245, 2 L. Ed. 2d 1503; we conclude that the judge issuing the warrant, taking this commonsense approach, could reasonably and logically find that there was probable cause to search the apartment specified in the warrant and to issue the warrant. In view of the contrary conclusion reached in the dissenting opinion, we have printed in full the affi*629davit and application1 for the search and seizure warrant on. the basis of which the warrant was issued.
The defendant next contends that the judge who issued the search warrant could not have reasonably found probable cause to issue it because the *630affidavit supporting the application for the warrant did not state the date on which the informant made his observations of narcotic activity. In support of this contention, the defendant relies primarily on Rosencranz v. United States, 356 F.2d 310 (1st Cir.). In the first place, this reliance is misplaced. The *631determinative issue in Rosencranz was not the date the informant made the observations of suspected criminal activity but rather the date when he related these observations to the affiant-police officer. Id., 315. In the present case, the dates on which the Bridgeport police received the information from each of two different informants is stated. While there is no fixed test for finding the existence of probable cause, proof of its existence must include facts so closely related to the time of the issuance of the warrant as to justify a finding of the existence of probable cause at that time. “The facts and circumstances set forth in an affidavit submitted in support of the issuance of a search warrant should be current and timely, so as to indicate that the premises, person, place or thing to be searched presently contains the fruits of the crime.” Maride, “The Law of Arrest and Search and Seizure,” p. 223. An exception to this rule is where the court finds facts indicating the likelihood that there is a continuing criminal activity. United States v. Mustone, 469 F.2d 970 (1st Cir.); United States v. Johnson, 461 F.2d 285 (10th Cir.); State v. Austria, 55 Haw. 565, 524 P.2d 290; Johnson v. State, 14 Md. App. 721, 288 A.2d 622; note, 100 A.L.R.2d 525, 542; Markle, supra, 226. The facts indicating this continuity must satisfy the same requisites of reliability as other facts within the affidavit that purport to evidence probable cause. Whether the proof meets this test must be determined by the circumstances of each case. Sgro v. United States, 287 U.S. 206, 211, 53 S. Ct. 138, 77 L. Ed. 260; State v. DeNegris, 153 Conn. 5, 8-9, 212 A.2d 894. The basic criterion as to the duration of probable cause *632is the inherent nature of the crime. Bastida v. Henderson, 487 F.2d 860, 864 (5th Cir.). As the court there noted: “The circuits hold that where an affidavit recites a mere isolated violation then it is not unreasonable to believe that probable cause quickly dwindles with the passage of time. On the other hand, if an affidavit recites activity indicating protracted or continuous conduct, time is of less significance.” In the present case, the facts recited in the affidavit disclose that the defendant received 86 percent pure heroin from out of town, diluted it with milk sugar and packaged it in smaller packets in his apartment for later distribution. Prom such a portrayal of ongoing criminal activity, presented to the officers by two different informants, one nine days before the warrant was issued and the other only the day preceding the application for the warrant, the issuing magistrate could reasonably conclude that probable cause existed at the time the warrant was issued.
The defendant next attacks the affidavit asserting that it lacked sufficient corroboration of the informants’ statements. In support of his position, he cites Aguilar v. Texas, supra, 114, which stated that “[a]lthough an affidavit may be based on hearsay information and need not reflect the direct personal observations of the affiant, Jones v. United States, 362 U.S. 257, [80 S. Ct. 725, 4 L. Ed. 2d 697] the magistrate must be informed of some of the underlying circumstances from which the informant concluded that the narcotics were where he claimed they were, and some of the underlying circumstances from which the officer concluded that the informant, whose identity need not be disclosed, . . .- was ‘credible’ or his information ‘reliable.’ ”
*633The affidavit presented by Detectives Frank Kapostas and William Brackett of the Bridgeport police department contained information from two informants which information was in the form of underlying facts and not conclusions. Each informant was represented as being known to the affiants and as reliable, having given information which led to previous convictions. Each informant’s report in the affidavit provides important corroboration of the other’s information. In addition, the detectives investigated and discovered that the defendant had a lengthy police record and was on parole at the time. Further, the detectives themselves observed the defendant in the company of a known narcotics pusher during the month preceding the issuance of the search warrant. The information in toto was clearly sufficient and satisfied the requirements specified in Aguilar v. Texas, 378 U.S. 108, 84 S. Ct. 1509, 12 L. Ed. 2d 723, and State v. Grayton, supra, 107. The attack on the sufficiency of the affidavit is without merit.
The defendant next claims error in the conclusion of the trial court that the search and seizure warrant was legal, asserting that there is no indication in the transcript or record that the court in fact examined the warrant. The absence of such an indication is, however, not conclusive on the question of whether the court did in fact examine the warrant itself, and none of the defendant’s attacks on the search has been directed at the contents of the warrant itself. Bather, they all go to contest the sufficiency of the information contained in the affidavit and application for the warrant, and we have found all of these attacks to be without merit. Furthermore, the defendant has not attacked the finding of the court that the warrant was issued “to *634search for and seize narcotic drugs, dangerous drugs and narcotic paraphernalia” and that such articles were in fact seized as a result of the search.2
The defendant next claims that he did not receive a fair trial and that there was error in denying his motion for a mistrial. The motion for a mistrial was made after the court through its own questions elicited from a witness, Sergeant John Seniber of the Bridgeport police department, that in his opinion the approximate value of the heroin in one of the packages seized in the defendant’s apartment was $11,000. The basis for the motion was a claim that this testimony was irrelevant to the crime charged, speculative on the part of the witness in that it had no basis in the facts then in evidence, and was inflammatory and prejudicial to the defendant. In addition, the defendant asserts that the witness’ valuation of the heroin was based on the-assumption that it was pure heroin, a fact not in evidence. Subsequent to this testimony, the state toxicologist testified that the substance seized from the defendant’s apartment was not pure heroin but was at least eighty percent milk sugar. He estimated the value of the heroin seized at several hundred dollars. Thereafter, the court struck the testimony of Sergeant Sember concerning his valuation of the heroin and in no uncertain terms instructed the jury to disregard it totally.
*635It is well established that “a mistrial should be granted only as a result of some occurrence upon the trial of such a character that it is apparent to the court that because of it a party cannot have a fair trial and the whole proceedings are vitiated.” Ferino v. Palmer, 133 Conn. 463, 466, 52 A.2d 433; State v. Leopold, 110 Conn. 55, 60, 147 A. 118; see also Goggins v. Reinzo Trucking Co., 166 Conn. 240, 250, 348 A.2d 569; State v. Savage, 161 Conn. 445, 449, 290 A.2d 221. The court has wide discretion in passing on motions for mistrial. Ferino v. Palmer, supra. In light of the court’s careful and explicit instructions to the jury when it discovered the possibility that irrelevant and mistaken testimony had been given, we can find no abuse of its discretion in the denial of the defendant’s motion for a mistrial.
The defendant next assigns error to several evidentiary rulings made by the court during the course of the trial. He first claims error in the admission of physical and testimonial evidence based on the claim that this evidence was the product of an illegal search and seizure. Having determined that the search and seizure was lawful and constitutional, it follows that evidence which resulted from that search was clearly admissible.
The defendant also assigns error to the rulings of the trial court sustaining the state’s objection to certain questions propounded during cross-examination of witnesses by the defendant’s counsel. These questions'attempted to elicit from police officers, who had taken part in the search of the defendant’s apartment, testimony concerning the defendant’s wife’s involvement with the narcotics which were found there. The state objected on the grounds of irrelevance and its objections were sustained. *636The defendant argued that he was entitled to present evidence, as an alternative explanation for the presence of the drugs, that the narcotics in his apartment were his wife’s and not his.
The trial court has broad discretion in determining the relevancy of evidence. Johnson v. Newell, 160 Conn. 269, 276, 277, 278 A.2d 776; State v. Carnegie, 158 Conn. 264, 273, 259 A.2d 628, cert. denied, 396 U.S. 992, 90 S. Ct. 488, 24 L. Ed. 2d 455; State v. Smith, 157 Conn. 351, 355, 254 A.2d 447; State v. Keating, 151 Conn. 592, 597, 200 A.2d 724, cert. denied, sub nom. State v. Joseph, 379 U.S. 963, 85 S. Ct. 654, 13 L. Ed. 2d 557. “Evidence is admissible when it tends to establish a fact in issue or to corroborate other direct evidence in the case. One fact is relevant to another fact whenever, according to the common course of events, the existence of the one, taken alone or in connection with other facts, renders the existence of the other either certain or more probable. Unless excluded by some rule or principle of law, any fact may be proved which logically tends to aid the trier in the determination of the issue. Evidence is admitted, not because it is shown to be competent, but because it is not shown to be incompetent. No precise and universal test of relevancy is furnished by the law, and the question must be determined in each case according to the teachings of reason and judicial experience. State v. Towles, 155 Conn. 516, 523, 235 A.2d 639; Pope Foundation, Inc. v. New York, N.H. & H.R. Co., 106 Conn. 423, 435, 138 A. 444.” Federated Department Stores, Inc. v. Board of Tax Review, 162 Conn. 77, 82, 291 A.2d 715. The trial court has wide discretion as to the scope of cross-examination as well. State v. Brathwaite, 164 Conn. 617, 619, 325 A.2d 284. In view of the fact that only the defendant was on trial *637and not his wife, and that there had been no mention on direct examination of his wife’s connection with the narcotics seized, we conclude that the trial court did not abuse its discretion in ruling as it did. The finding clearly indicates that the defendant did introduce evidence in his offers of proof that his wife was an addict, had used heroin, and had used a set of works similar to that seized from his apartment.
The defendant also assigned as error the court’s denial of his motion to dismiss the habitual offender portion of the information which alleged that he had twice before been convicted, sentenced and imprisoned in the state prison. The charge was made pursuant to the provisions of § 54-121 of the 1958 Eevision of the General Statutes which prescribed indeterminate sentences to the state prison “provided, when any person so sentenced has twice before been convicted, sentenced and imprisoned in a state prison or penitentiary, the court shall sentence such person to a maximum of thirty years.” It is the defendant’s claim that the statute was unconstitutional because it violated the equal protection clause of the United States constitution and the imposition of the prescribed sentence amounted to cruel and unusual punishment. In State v. Mead, 130 Conn. 106, 109, 32 A.2d 273, and State v. Grady, 153 Conn. 26, 35, 211 A.2d 674, we decided against the validity of just such contentions and there is no need to repeat what we said there. Neither the record in this case nor the passage of time since our decisions in those cases persuades us to a result different from that reached in those cases.
The defendant’s final assignment of error is addressed to the sentence imposed by the trial court. *638It is Ms claim that the severity of the sentence imposed appears to have been influenced by a mistake on the part of the court as to the amount of heroin found in the defendant’s apartment. In its remarks at the time of imposing sentence, the court attempted to calculate the value of the heroin seized. It appears that in doing so the court based its calculations on the mistaken assumption that there are 479 grams in an ounce. The defendant was sentenced to not less than ten years nor more than thirty years in the Connecticut state prison. The thirty-year maximum term was mandated under § 54-121 as it applied to habitual offenders. The ten-year minimum term was the maximum term then prescribed for a first offense under § 37 (a) of the 1967 Public Acts, No. 555 (now General Statutes §19-481 [a]). 1969 Public Acts, No. 753, §19, decreased the maximum term for a first offense from ten to five years.
The sentence as imposed was within the limits fixed by statute for the offense charged. We have no discretionary power in such a case except where a trial court appears to have abused its discretion. State v. LaPorta, 140 Conn. 610, 612, 102 A.2d 885; State v. Van Allen, 140 Conn. 39, 44, 97 A.2d 890; State v. Horton, 132 Conn. 276, 278, 43 A.2d 744. That does not appear to be the case here. Two other factors are also of sigmfieance. First, it does not appear that the present claim was ever made to the trial court at the time of sentence. See Practice Book § 652; State v. Malley, 167 Conn. 379, 386, 355 A.2d 292, and cases cited therein. Second, although the defendant on appeal assigned as error the comments of the court and the imposition of the sentence to which objection is now pressed, the court refused to make any corrections. Inherent in the present *639argument of the defendant is an assumption that despite the court’s refusal to make any change in the sentence as imposed that sentence was predicated solely on the court’s misconception of the quantity of heroin found in his possession. This assumption is unwarranted in view of the information obtained by the court during the trial and that made available to it in the report submitted before sentence by the adult probation office. See Greneral Statutes § 54-109. Of particular relevance in consideration of the penalty imposed is the information submitted to the court that on September 27, 1945, the defendant had been convicted of robbery with violence and sentenced to prison for a term of not less than five years nor more than seven years and that on October 27, 1955, he was convicted of the crimes of robbery with violence, breaking and entering with violence and escape (from jail) with violence and sentenced to prison for the term of not less than twelve years nor more than twenty-five years. These convictions and sentences were proper for the consideration of the court not only in fixing the maximum sentence under the habitual offender statute but in fixing the minimum sentence. If the defendant were of the opinion that his sentence should have been reconsidered, his remedy was by application to the review division of the Superior Court in accordance with the provisions of §§ 51-194 through 51-196 of the Greneral Statutes. See Kohlfuss v. Warden, 149 Conn. 692, 697, 183 A.2d 626, cert. denied, 371 U.S. 928, 83 S. Ct. 298, 9 L. Ed. 2d 235.
There is no error.
In this opinion Loiselle and Longo, Js., concurred. Bogdanski, J., concurred in the result.
