For liquids, several denominations have heretofore been adopted, namely, for beer, the firkin of 9 gallons, the kilderkin of 18 , the barrel of 36, the hogshead of 54; and the butt7 of 108 gallons. For wine or spirits there are the anker, runlet, tierce, hogshead, puncheon, pipe, butt, and tun; these are, however, rather the names of the casks, in which the commodities are imported, than as express any definite number of gallons.
