In the quot. which J. cites from Ayliffe Parergon 301 `Institution without induction does not make a plenary against the king, where he has a title to present', plenary is a misprint for plenarty, which Ayliffe has in the correct spelling on the same page and elsewhere; cf. quot. 1791 in PLENARTY 1.
