TITHING, Eng. law. Formerly a district containing ten men with their fam-ilies. In each tithing there was a tithing man whose duty it was to keep the peace, as a constable now is bound to do. St. Armand, in his Historical Essay on the Legislative Power of England, p. 70, expresses, an opinion that the tithing was composed not of ten common families, but of ten families of lords of a manor.
