1911 Encyclopædia Britannica (1911)
“ The “imperial bushel”, legally established in Great Britain in 1826, contains 2218.192 cub.in., or 80 ℔ of distilled water, determined at 62° F., with the barometer at 30 in. Previously, the standard bushel used was known as the “Winchester bushel”, so named from the standard being kept in the town hall at Winchester; it contained 2150.42 cub. in. This standard is the basis of the bushel used in the United States and Canada; but other “bushels” for use in connexion with certain commodities have been legalized in different states. ”
