The former holding, however, seems to have originated in Pecina v. State, supra, wherein the Court ruled, in the face of a claim that the warrant affidavit contained no showing the informant could readily recognize contraband: "The affidavit presented here is substantially the same as that approved by this court in Wetherby v. State, Tex.Cr.App., 482 S.W.2d 852. See also Cummins v. State, Tex.Cr.App., 478 S.W.2d 452.
In Phenix v. State, Tex.Cr.App., 488 S.W.2d 759, on p. 765, we said: 'In Wetherby v. State, (Tex.Cr.App.) 482 S.W.2d 852 (1972) this court said: '. . . it is well settled that a court will not look behind the allegations of an affidavit for the issuance of a search warrant. Brown v. State, 437 S.W.2d 828 (Tex.Cr.App.1968).
The affidavit stated that the informer had been in the appellant's apartment within six hours and had observed her remove a brown paper bag, from a drawer of a chest in the bedroom, which contained approximately one hundred foil wrapped packets of heroin. The affidavit presented here is substantially the same as that approved by this Court in Wetherby v. State, Tex.Cr.App., 482 S.W.2d 852. See also Cummins v. State, Tex.Cr.App., 478 S.W.2d 452.
In determining the sufficiency of the affidavit, we are bound by the four corners of the document. Gaston v. State, 440 S.W.2d 297 (Tex.Cr.App. — 1969) (Onion, J., concurring), cert. denied, 396 U.S. 969, 90 S.Ct. 452, 24 L.Ed.2d 435; Wetherby v. State, 482 S.W.2d 852 (Tex.Cr.App. — 1972). Examining the affidavit in such manner, we hold that it does reflect adequate probable cause and sufficient 'underlying circumstances' to satisfy the requirements of Aguilar v. Texas, 378 U.S. 108, 84 S.Ct. 1509, 12 L.Ed.2d 723. Appellant's first ground of error is overruled.
In his ninth ground of error appellant alleges that the trial court erred in sustaining the State's objection to defense counsel's request for the names of the persons described in the affidavit supporting the search warrant as "users and sellers of narcotics' who were seen frequenting appellant's apartment. In Wetherby v. State, 482 S.W.2d 852 (1972), this court said, ". . . it is well settled "that a court will not look behind the allegations of an affidavit for the issuance of a search warrant." Brown v. State, 437 S.W.2d 828 (Tex.Cr.App. 1968)."
See, Adair and Via v. State, 482 S.W.2d 247 (Tex.Cr.App.1972). Yantis v. State, 476 S.W.2d 24 (Tex.Cr.App.1972); Wetherby v. State, 482 S.W.2d 852 (Tex.Cr.App.1972). It is observed, however, that Officer Presley knew there was a car as described by the informer.
