GALLON, an English measure of capacity, usually of liquids, but also used as a dry measure for corn. A gallon contains four quarts. The word was adapted from an O.Nor.Fr. galon, Cen tral Fr. jalon and was Latinized as galo and galona. It appears to be connected with the modern French jale, a bowl, but the ultimate origin is unknown; it has been referred without much plausibility to Gr. 'yavXos, a milk pail. The British imperial gallon of four quarts contains 277-274 cu.in. The old English wine gallon of 231 cu.in. capacity is the standard gallon of the United States.
