The remedy in equity is more effective; as, between co-sureties. 1 But there is "no contribution between wrongdoers." This rule applies appropriately only to cases where there has been intentional violation of law, and where the wrong-doer is to be presumed to have known that the act was unlawful. It fails when the injury grows out of a duty resting primarily upon one of the parties, and but for his negligence there would have been no cause of action against the other. A servant is liable to his master for the damages recovered against him in consequence of the negligence of the servant.3 A municipality, made to pay damages for an injury resulting from the negligence of a private citizen, may recover the amount from the citizen. See AvERAGE, General; JOINT. 1. The etymological meaning (which see, below) seems to be preserved in the offense termed criminal conversation: adultery regarded as an injury to the husband, entitling him to damages in a civil action.5 The abbreviation “crim, con." has acquired a fixed and universal signification which the courts will take notice of without proof.6 The development of the word has been substantially as follows: L. conversatio, frequent use, habitual abode, intercourse: conversari, to turn to often, to dwell, live with. (1) Manner of living; habits of life; behaving, behavior; conduct; life. 1 Guerin v. Reese, 33 Cal. 297 (1867). 2 Little Rock, &c. R. Co. v. Eubanks, 48 Ark. 467 (1886); 22 N.
