§ Dr. Gilbertasked the Chancellor of the Exchequer what, in calculating the average specific gravity of beer subject to duty in any year, the Customs and Excise use, the mean, the median or the mode of the total range of specific gravities; and whether they weight their calculations for the volumes involved.
§ Mr. HigginsThe average gravities of beer published by Customs and Excise are weighted mean gravities, calculated from the original gravities and net quantities of the unfermented worts on which duty has been charged.
