ve defenses that it has pleaded. Seale v. Nichols, 505 S.W.2d 251 (Tex.Sup.1974).
The summary judgment proof presented by the appellant at the hearing consisted of the affidavits of John Taylor and a bookkeeper for John Taylor Co. The appellee alleges that neither affidavit contains a seal as required by Tex.Rev.Civ.Stat. Ann. art. 23, § 18 (1969), and, therefore, the affidavits are fatally defective. We reject that argument. Although our copies of these two affidavits do not contain visible seals, neither does the copy of the affidavit of the appellee's counsel.

Although written in the form of an acknowledgment, the sentence does not purport to be a statement that the affiant executed a written instrument for the consideration and p
