Frеdderick D. Jones was convicted in the district court of seven counts of distribution of cocaine base in violation of 21 U.S.C. § 841(a)(1). He challenges his conviction on the ground that the evidence was legally insufficient to support his convictions. He also contests the district court’s denial of his motion to suppress evidence as well as its denial of his motion for a mistrial. Finally, he also raises several challenges to the legality of his sentence. For the reasons set forth in the following opinion, we affirm the judgment of the district court.

BACKGROUND
The charges against Mr. Jones arose out of an investigation conducted by the St. Clair County Sheriffs Department. Deputy Singleton of that department testified that, while operating as an undercover agent, he purchased, on seven occasions between August 2, 1993 and September 15, 1993, crack cocaine from Mr. Jones. Each transaction *1288 was witnessed by other law enforcement officers. In the final transaction, Deputy Singleton had used one fifty-dollar bill, two twenty-dollar bills, and one ten-dollar bill. The serial numbers of those bills had been recorded prior to the transaction.
After this final purchase, Captain Terrence Delaney of the St. Clair County Sheriff’s Department applied for a warrant to search the house where the transactions had occurred. The application and affidavit for the search warrant listed the serial numbers of the bills used for the final drug purchase. It also recited that this currency was the object of the search. On the basis of this affidavit, a search warrant was authorized by a United States magistrate judge. Although the affidavit listed the serial numbers of each of the bills, the warrant itself simply described the property to be seized as “United States Currency.”
On the same day, September 15, 1993, the warrant was еxecuted. Approximately six officers of the St. Clair County Sheriffs Department conducted the search of the residence. These officers were under the supervision of Captain Delaney. Prior to the execution of the warrant, Captain Delaney held a meeting and instructed the officers that the warrant had been issued for specific currency only and that they were to seize no other property. He further ordered them to cease all searching once the currency was found. During the execution of the warrant, the members of the search team cоnducted simultaneously a search of three bedrooms. Captain Delaney acted as supervisor. When an officer located a quantity of currency, he brought it to Captain Delaney. The Captain then examined the currency and compared the serial numbers with the numbers he had listed on the application for the warrant. Once he determined that the numbers on the currency matched the numbers on the application, Captain Delaney ordered the officers to cease their search.
During the execution of the search warrant, the officers observed other items of evidence. However, in accordance with Captain Delaney’s previous order, none of this evidence was seized. Captain Delaney then applied for a second search warrant which would permit the seizure of the evidence that had been found during the earlier search but had not been seized. This evidence included a file cabinet, crack cocaine, additional United States currency, a triple beam scale, two police scanners, four firearms, and a quantity of marijuana.
Mr. Jones was charged with seven counts of distributing сocaine base. He was also charged with single counts of possession with intent to distribute cocaine base, using or carrying a firearm during and in relation to a drug trafficking offense, and possession of a firearm by a felon. After a hearing, the district court denied the motion to suppress the evidence seized during the first search. At the trial, held January 18-20, 1994, Captain Delaney, Deputy Sheriff Singleton, and various expert witnesses testified. Another witness was Felicia Brown, a girlfriend of the defendant, who was present at the residence when the warrant was executed. She testified that, during the period she lived with Mr. Jones, he had sold drugs and she had witnessed the transactions. According to her testimony, he had sold crack cocaine to at least twenty people a day. She also testified that he would hold a gun behind his back when he answered the door of the residence and then would place the gun under a couch if he recognized the customer. She identified the weapon exhibited by the government as one that resembled the firearm that she had seen Mr. Jones possess at the residence.
At the end of trial, the jury began its deliberations. In the first hour of deliberation, one juror sent a note to the court complaining of a headache. The court instructed the jury to cease temporarily its deliberations and to have lunch. It then interviewed the juror who had sent the note. She explained that she had a headache caused by asthma and sinus problems. While she rested, the court and the attorneys discussed the available options. After lunch, the juror advised the court that she was feeling better and that she could continue with the deliberations. When the court informed her that it had decided that it would suspend deliberations for the remainder of the day to allоw her to recuperate, the juror responded: “Well, I feel that we might as *1289 well just go on with it and get it over with, because I drank a pop. And it kind of helped.” (Tr.Vol. Ill, p. 47). The court then denied Mr. Jones’ motion for a mistrial and allowed the jury deliberations to proceed. The jury returned a verdict of guilty with respect to Counts I through VIII. The court, however, later determined that the verdict form on Count VIII was defective and therefore dismissed that count. The jury found Mr. Jones not guilty of the firearm counts.
At the sentencing proceeding, the district court determined that a total offense level of 28 was apprоpriate and that Mr. Jones’ prior criminal history warranted a category of III. The court sentenced Mr. Jones to a term of 121 months’ imprisonment.

DISCUSSION
1.
We address first Mr. Jones’ contentious with respect to the finding of guilt. His claim that the evidence submitted by the government was legally insufficient to support a finding of guilt need not detain us long. By bringing such a challenge, a defendant bears a “heavy burden.”
United States v. Scroggins,
We also note that the evidence supporting the conviction of Mr. Jones was substantial. The record shows that all seven drug transactions were observed by other officers, that the currency which Deputy Singleton used to purchase the сocaine on the seventh and last occasion was recovered from the defendant’s residence, and that the defendant orally confessed to being a drug dealer. Mr. Jones’ claim that the evidence of record does not support the jury’s verdict is without merit.
2.
Mr. Jones also presents two claims grounded in the Fourth Amendment. First, he submits that the first search warrant was overly broad because it described the object of the search as simply “United States currency, which is property that constitutes evidence of a criminal offense, in violation of Title 21, United States Code, Seсtion 841(a)(1).” Second, he contends that the search, as executed, violated the Fourth Amendment because only the supervising officer, one of approximately six officers involved in the search, knew the serial numbers of the currency sought. Consequently, the other officers continued to search while the supervising officer checked the serial numbers on discovered bills. This procedure, he submits, extended the period of time in which the officers were free to rummage among the property in the residence and to identify other items of evidéntiary value.
We turn first to the contention that the warrant was overbroad because it did not contain the serial numbers of the bills sought as evidence. In analyzing this claim, we begin with the well-established proposition that “[t]he proceeding by search warrant is a drastic one, and must be carefully circumscribed so as to prevent unauthorized invasions of the sanctity of a man’s home and the privacies of life.”
Berger v. New York,
When the situation is evaluated in light of the purposes of thе warrant requirement, we believe that the warrant in this case complied with the mandate of the Constitution that the items to be seized be described with particularity. “Although the fourth amendment requires that a search warrant describe the objects of the search with reasonable specificity, it need not be elaborately detailed.”
United States v. Som-ers,
If the affidavit submitted in support of the warrant had been appended physically *1291 to the affidavit by the magistrate judge, our inquiry into this matter cоuld end here.. Although Mr. Jones’ imprecise reference to this specific problem barely preserves the issue for appellate review, an ambiguity in the record requires that we deal with a related matter that bears on the issue of particularity. On this record, we cannot be sure that the affidavit submitted in support of the search was in fact appended to the warrant and was served along with the warrant. Although the warrant acknowledges the existence of the affidavit, it does not explicitly recite that the affidavit is incorporated by reference or that it was аttached to the copy served upon execution.
The case law is not in agreement with respect to whether the affidavit supplying the requisite specificity must be appended physically to the warrant.
See United States v. Towne,
In this case, several factors militate in favor of our concluding that this warrant be considered as containing the requisite particularity. At the outset, we note that there is no serious doubt that the magistrate judge considered the affidavit in issuing the warrant. It is clear that he directed that the original of the affidavit be filed with the warrant. It is equally evident from the record that Captain Delaney, the officer in charge of conducting the search, had in his possession the serial numbers of the currency listed in that affidavit, that he limited the search to those items described in the warrant, and that he made a return to the magistrate that conformed to the warrant and affidavit. Under the circumstances presented here, therefore, reliance on the affidavit to supply the requisite specificity is compatible with the values protected by the Fourth Amendment.
We now turn to an examination of whether the search was conducted in a manner that comports with the reasonableness requirement of the Fourth Amendment. The officers were told that they were to search for specific United States currency. There is no suggestion that the officers searched in places where currency could not be found. Once it was verified that they had found the currency in question, the search stopped. Nothing else was seized at that time. The house was sealed, a second warrant obtained, and the other evidence against the defendant was then seized during a second search.
The search methodology employed by the supervising officer is not constitutionally infirm. The Fourth Amendment requires that the officers executing the warrant employ a methodology that is, in light of the values protected by the Fourth Amendment and the exigencies of the situation, a reasonable one. 4 The officers no doubt had the obligation to take reasonable steps to minimize the intrusion necessary for the location of the items named in the warrant. The use of several officers certainly increased the chances of identifying the sought bills quickly and therefore minimized, at least temporally, the degree of intrusion caused by the execution of the warrant. With the advantage of hindsight, it is possible to suggest a better approach for the reconciliation of those competing interests. It might have been possible for the supervising оfficer to have furnished each of the officers with a copy of the serial numbers and therefore to have minimized further the time necessary to locate the currency that was the object of the search. We cannot say, however, that the failure to take that extra step was a lapse of constitutional dimension. Under the circum *1293 stances here, the supervisory officer’s methodology cannot be called unreasonable. Moreover, Mr. Jones can claim no real harm here. The currency, which was the object of the search, was located in a file folder together with a quantity of crack cocaine. In addition, by the time of the discovery of the currency, the officers had apparently already observed, but not seized, other items of evidence. Whatever items were observed in the minimum time it took the officer who discovered the bills to check the numbers with his supervisor were cumulative in the subsequent determination of probable cause for the second warrant.

Within an hour after the jury had begun deliberations, Juror Hayes sent the court a note which read “My head hurts too badly. I can’t think.” The court ordered delibеrations to cease and Juror Hayes was given the opportunity to rest. After consultation with counsel, the district court tentatively decided to recess further jury deliberations and to resume the next day. When Juror Hayes was informed of this decision, however, she stated: “Well, I feel that we might as well just go on with it and get it over with, because I drank a pop. And it kind of helped.” Troubled by Juror Hayes’ wish to “get it over with,” the defendant moved for a mistrial. The district court denied the motion.
We review the denial of a mistrial under the abuse of discretion standard.
United States v. Canino,
4.
Mr. Jones next submits that § 2Dl.l(a)(3) 5 of the United States Sentencing Guidelines is unconstitutional. The district court found that Mr. Jones’ relevant conduct involved 7.7 grams of cocaine base. Under § 2Dl.l(a)(3) and (c), the base offense level for this quantity of cocaine base is 26. The base offense level for an identical quantity of cocaine powder, however, is only 12 under § 2Dl.l(a)(3) and (c). Mr. Jones claims that this disparity in sentencing violates his right to equal protection because the enhanced penalty for cocaine base has a disproportionate impact on African-Americans. He further submits that this disparity is irrational because no scientific evidence *1294 has established that cocaine base is any more dangerous than cocaine powder.
As Mr. Jones frankly recognizes, this court has already squarely addressed and rejected these arguments in
United States v. Chandler,
5.
Mr. Jones also challenges the district court’s decision to increase his base offense level by two levels under § 2Dl.l(b)(l) fоr possessing a firearm during the commission of the drug offenses for which he was convicted. The defendant contests this decision because the jury had found him not guilty of the two firearm possession-related charges for which he had been indicted. 7 We believe, however, that the district court’s decision is permitted by the law of the circuit.
First, it is clear that there is no automatic bar to the action taken by the district court. As we noted in
United States v. Ewing,
We still must review for clear error the district court’s factual finding that the defendant possessed a firearm in connection with these drug offenses.
See United States v. Brown,
Conclusion
The district court committed no reversible error with respect to the adjudication of guilt *1295 or the imposition of sentence. Accordingly, the judgment of the district court is affirmed.
AFFIRMED.
Notes
.
See Brown,
.
See United States v. Nafzger,
. This practical approach was evident in a case somewhat similar to our own. In
United States v. Bright,
.
Cf. Illinois v. Rodriguez,
. Because Mr. Jones was sentenced on April 8, 1994, the Guidelinеs effective November 1, 1993 are applicable. Section 2D1.1(a)(3) provides:
§ 2D 1.1 (a) Base Offense Level (Apply the greatest):
(3) the offense level specified in the Drag Quantity Table set forth in subsection (c) below.
§ 2Dl.l(c), the Drag Quantity Table, lists "at least 5 G but less than 20 G of cocaine base" at Level 26. It also lists “less than 25 G of Cocaine” at Level 12.
. Mr. Jones states that this issue has been raised in order to preserve it in the event that the United States Supreme Court holds this sentencing disparity to be unconstitutional. Appellant's Br. at 16.
. Mr. Jones was charged with the use or carrying of a firearm in relation to a drug trafficking crime in violation of 18 U.S.C. § 924(c) and with being a felon in possession of a firearm in violation of 18 U.S.C. § 922(g)(1).
