The Redistribution of Seats Act 1885 (48 & 49 Vict., c. 23) was an Act of the Parliament of the United Kingdom. It was a piece of electoral reform legislation that redistributed the seats in the House of Commons, introducing the concept of equally populated constituencies, a concept in the broader global context termed equal apportionment, in an attempt to equalise representation across the UK. It was associated with, but not part of, the Reform Act 1884 .
Zincography was a planographic printing process that used zinc plates. Alois Senefelder first mentioned zinc’s lithographic use as a substitute for Bavarian limestone in his 1801 English patent specifications. In 1834, Federico Lacelli patented a zincographic printing process, producing large maps called géoramas. In 1837-1842, Eugène-Florent Kaeppelin perfected the process to create a large polychrome geologic map.
