The district judge suppressed evidence obtained during a search of the defendant’s residence because he concluded that the search warrant was based on an affidavit that failed to establish probаble cause. Because in our judgment the magistrate properly ruled that the affidavit established probable cause, we reverse and remand for further proceedings.
The “Affidavit for Search Warrant” was exеcuted by John T. Pool, a special agent of the Drug Enforcement Administration (DEA), and it recounts the following facts: In August 1981, a representative of a New Jersey glass manufacturer communicated with Agent Pool. The reprеsentative indicated that the firm had recently shipped glassware and laboratory equipment to a “Fooladi Enterprises” in El Paso, Texas. When one of the firm’s salesmen tried to call .on Fooladi Enterprises, however, he discovered a personal residence at the address instead of the commercial building he expected.
In May 1982, a Dr. E.H. Williams ordered ■25 pounds of sodium acetate anhydrous from a San Antonio, Tеxas company. The chemical was shipped by Greyhound Bus to Laredo. It was picked up by Williams, who placed a new shipping label on the package and sent it to Dr. Mike Fooladi in El Paso, Texas. A confidential informant advised the DEA that Williams had a reputation for supplying illegal drugs to the horse racing industry.
Fooladi picked up the sodium acetate anhydrous on June 1, 1982, and took it to his *182 residence. The following day, Agent Poоl returned to the Fooladi residence with another DEA agent. From a distance of 100 yards, they smelled a strong odor originating at the Fooladi house. They recognized the odor as similar to that present at other lоcations where amphetamines or methamphetamines were being manufactured. Pool “believe[d] ... it [was] the odor of phenyl acetic acid.”
The agents moved closer to the residence. They sаw a prefabricated-type building located in the Fooladi back yard. The odor seemed to come from this structure. Dr. Fooladi was observed leaving the building wearing a pair of surgical gloves. He held his hands awаy from his body as if there was something on them.
DEA chemists advised Pool that sodium acetate anhydrous, the chemical shipped to Fooladi from San Antonio, is a common chemical. It has many legitimate uses, but is also аn essential element in the manufacture of phenyl-2-propanone, an immediate precursor to amphetamines and methamphetamines. The chemists indicated that it could easily be purchased frоm several chemical supply companies in El Paso. They also told Pool that most laboratories working legitimately with phenyl acetic acid, the chemical Pool smelled at the Fooladi residence, would have a filtration system to prevent the discharge of odorous fumes.
Finally, Agent Pool discovered that Dr. Fooladi had listed his employment as “Med School Juarez” in an application for credit with an El Pаso company. However, United States Customs computers indicated that, in the preceding month, Fooladi had crossed the border on only two occasions.
Based on this information, a United States Magistrate issuеd a warrant to search Fooladi’s residence. The search was conducted, and Fooladi was subsequently indicted for manufacture and attempted manufacture of controlled substances in violation оf 21 U.S.C. §§ 841(a)(1), 846 (1976). Fooladi filed a pretrial motion to suppress the evidence seized during the search of his residence. The district court granted the motion, and the government brought this appeal. 1
I
Fooladi’s brief states thаt the “Affidavit for Search Warrant” was not sworn to or attested. The full affidavit was not contained in the record originally forwarded to us by the district court. Because the fourth amendment provides that “no Warrants shall issue, but upon probable cause, supported by Oath or affirmation,” U.S. Const, amend. IV, we remanded the case so the full affidavit could be included in the record. As supplemented, the record contains an “Affidavit for Search Warrant” sworn by John T. Pool of the DEA before Janet Ruesch, a United States Magistrate. Attached to the affidavit, and incorporated therein by reference, is a four-page rider. Fooladi’s claim that the affidavit on which the warrant issued was unsworn is contradicted by the record.

The government argues that the district court erred in refusing to consider the information furnished to Pool by the representative of the glass manufacturing сompany and by the confidential informant who advised that Dr. Williams had a poor reputation. The district court discounted this information because the affidavit failed to indicate why Pool concluded the informatiоn he received from these sources was reliable.
See Aguilar
v.
Texas,
The district judge erred in discounting the information supplied by the glass manufacturing company. We have often noted that
“Aguilar
and
Spinelli
requirements are limited to the informant situation only.”
United States
v.
Bell,
457 F.2d
*183
1231, 1239 (5th Cir.1972);
accord United States
v.
Darensbourg,
The exact scope of the “non-profеssional-informant” exception to the rule of
Aguilar
and
Spinelli
is as yet unclear in this Circuit.
See United States v. Flynn,
The non-professional informant cases often stress the fact that the information cаme from an identified source.
See Darensbourg,
Our conclusion is different with respect to the information regarding Dr. Williams’ reputation. The affidavit states that a DEA agent “inquired with a confidential informant of his who is also a practicing veterinarian,” and receivеd this information. The affidavit thus does not establish that the informant was a “non-professional” within the meaning of the rule discussed above. Aguilar and Spinelli, therefore, required the affidavit to set forth the reasons for concluding that this informant was credible. It did not do so. For this reason, the district court properly discounted the information furnished by this informant.

“[PJrobable cause exists whenever the facts and circumstances known to the officer, and of which he hаs reasonably trustworthy information, are sufficient to warrant a person of reasonable caution to believe that an offense has been or is being committed.”
United States v. Head,
The magistrate’s determination that probable cause was shown by the affidavit, however, is entitled to great deference.
*184
See United States v. Smith,
In evaluating the showing of probable cause, we are mindful that the question is one of “factual and practical considerations on which reasonable and prudent men, not legal technicians, act.”
Brinegar,
Applying these principles to the affidavit in the present case, we conclude that it established probable cause. Fooladi obtained glassware and equipment that might be used to manufacture amphetaminеs. Although sodium acetate anhydrous was available locally, he obtained the chemical from San Antonio. He arranged not to have it shipped directly to him; instead he had it sent to Dr. Williams who received it in Laredo and forwarded it to El Paso. The agents smelled phenyl acetic acid emanating from a building on Fooladi’s property. This odor is produced during the manufacture of phenyl-2-propanone.
Cf. United States v. Michel,
Many of these facts, considered in isolation, are quite innocent. A citizen may purchase glassware аnd laboratory equipment for perfectly legitimate purposes. He may buy chemicals for legitimate purposes. He may even have products routed in a roundabout fashion innocently. However, we consider the evidence as a whole, and “[vjiewing the evidence in this manner it may truly be said that the total may be a sum greater than its parts.”
Flynn,
For these reasons, the district court’s ruling on the suppression motion is REVERSED and the case is REMANDED for further proceedings not inconsistent with this opinion.
Notes
. 18 U.S.C. § 3731 (1976) permits the United States to appeal “from a decision or order of a district court suppressing or excluding evidence. ...”
