"Ascanius" (3rd S. vi. 349.)—Another edition of this work was published in Paisley in 1769, and bears the following title-page —

"Ascanius; or, the Young Adventurer, containing an impartial Account of the late Rebellion in Scotland: the Third Edition, with considerable Additions and Improvements. Paisley: Printed by Weir and M^cLean for James Davidson & Co., at Fergusley, near Paisley, Mdcclxix."

Printing was commencing in Paisley that year, and the partners of the firm were Alexander Weir, a bookseller, and Andrew M^cLean, a printer.

The inhabitants of Paisley took a considerable interest in the publication. The chief magistrate of Paisley having been summoned by the secretary of Prince Charles on Sunday, December 29,1745, and appeared before him on Monday, the town was fined in 1000/. for raising 200 militiamen, but it was afterwards reduced to 5001. by the prince. Bailie Kyle was detained as a hostage till Friday morning, January 3,1746, when the fine was paid, and Ascanius, with his Highland troops, left Glasgow. The Paisley militia were at the battle of Falkirk, on January 17, 1746, and had eight men killed. S.
