The word is in O.E. bolla, which is also represented in "bowl," a round vessel for liquids, a variant due to "bowl," ball, which is from the Fr. bottle. "Boll" is also used, chiefly in Scotland and the north of England, as a measure of weight for flour=14o lb., and of capacity for grain, 16 pecks= l boll.
