Lefkoff v. Sicro, 189 Ga. 554 (10) ( 6 S.E.2d 687, 133 ALR 738); Jackson v. Sanders, 199 Ga. 222, 227 ( 33 S.E.2d 711, 159 ALR 638); Guardian Life Ins. Co. v. McMichael, 74 Ga. App. 53 ( 38 S.E.2d 689); DeKalb County v. Brewer, 107 Ga. App. 231, 233 ( 129 S.E.2d 540). In Galloway v. General Motors Acceptance Corp., 107 Ga. App. 334 ( 130 S.E.2d 176), this court recently held that: "The allegations of the petition which stated that the defendant was indebted to the plaintiff in the sum of $450.36 on a contract (a copy of which was attached to the petition as an exhibit), said sum being past due and unpaid, were sufficient to set forth a cause of action as against general demurrer ( J. C. Pirkle c. Co. v. Lester, 79 Ga. App. 512, 54 S.E.2d 298); and were not subject to special demurrer upon the ground that it was not alleged what amounts the defendant had paid upon the automobile and when such payments were made. C. I. T. Corp. v. Davis, 49 Ga. App. 634 (2) ( 176 S.E. 821)." (Emphasis supplied.)
