This page is from a notebook belonging to engineer Bryan Donkin containing medicinal remedies and other compositions (for example to prevent iron from rusting, for varnish), preservatives and culinary recipes. It details the process of how to make ivory paper according to a "Mr Enslie".
The Bryan Donkin Company was formed in 1803 in Bermondsey, South East London and moved to Chesterfield, Derbyshire in 1902. Bryan Donkin first commercialised paper making machinery and later moved into gas valve production.
