Mr. Bernalbegged to ask a question of the Chancellor of the Exchequer respecting a practice that had lately sprung up in the port of London, and in some of the outports. Formerly, a duty of 6d. used to be paid at the Custom-house on maps and prints, unless they belonged, and were attached to, a book, in which case they passed with the book, and were included in the duty of 51. per cwt. Lately, however, within the last six months, the Custom-house officers in London and at Dover had taken it into their heads to charge 6d. for every print or map which was contained in a book, besides the duty of 51. per cwt. He begged from the right hon. Gentleman an explanation of this novel proceeding.
