Notes:
Petition on behalf of James Leblanc and William Scot, masters of glass manufactories, against Sarah Dalrymple regarding her monopoly of importing mirrors free of duty. Dalrymple had applied to Parliament to be granted a monopoly to import mirrors duty free and Leblanc and Scot objected, citing such a monopoly would "ruine the glass manufactorie by which many families are kept at work..." and lead to the export of "vast sums of money now imployed in the kingdom" and "would render our own glass plate useless..."
James Leblanc, a French mirror-maker, was partners with William Scot, a cabinet-maker. Together, the men wanted to import rough plate glass which they argued was very different than importing the polished glass that Dalrymple wanted to import.
Details of the argument between Leblanc and Scott versus Dalrymple can be found in bib no. 68628, TP854.S4.T94.
