The Boundary Commissions in the United Kingdom are non-departmental public bodies responsible for determining the boundaries of constituencies for elections to the House of Commons, and areas of local government.
The Local Government (Boundaries) Act 1887 (50 & 51 Vict. c. 61) was an Act of the Parliament of the United Kingdom. The Act established boundary commissioners to reform the areas of administrative bodies in England and Wales in preparation for the creation of elected councils by the Local Government Act 1888. In the event, the recommendations of the commissioners were not carried out.
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.
