Tonnage and poundage Tonnage and poundage Tonnage and Poundage were certain duties and taxes first levied in Edward II's reign on every tun (cask) of imported wine, which came mostly from Spain and Portugal, and on every pound weight of merchandise exported or imported. Traditionally tonnage and poundage was granted by Parliament to the king for life until the reign of Charles I. Tonnage and poundage were swept away by the Customs Consolidation Act of 1787. Charles I's first Parliament, known as the Useless Parliament, broke with tradition and granted the king tonnage and poundage for a year rather than life out of
1/3–2/3 conjecture and 2/3, then there would not exist a pair "x", "y" in which "x" is earlier than "y" in a number of partial orderings that is between "q" and times the total number of partial orderings. More generally, let "P" be any series composition of three-element partial orders and of one-element partial orders, such as the one in the figure. Then "P" forms an extreme case for the 1/3–2/3 conjecture in the sense that, for each pair "x", "y" of elements, one of the two elements occurs earlier than the other in at most 1/3 of the linear extensions of
