The contract sued upon in the instant case was one of suretyship, and not one of guaranty (Watkins Medical Co. v. Marbach, 20 Ga. App. 691, 93 S. E. 270), and the court did not err in any of its rulings upon the demurrers and other pleadings, or upon the admissibility of evidence, or in directing a verdict in favor of the plaintiff and against all the defendants for the full amount sued for.

Judgment affirmed.
