a tack
Note by Heny Craik to Letters 46 from Journal To Stella

This was a device, then often resorted to by a dominant faction in the House of Commons, of joining some measure in which they were much interested to a Money Bill, which the House of Lords had no power to alter. On this occasion the extreme Tories (the October Club) tacked to a Lottery Bill another Bill for appointing Commissioners to examine into grants of lands by the Crown since 1688. It was, in fact, a revival of the very Bill which Swift had attacked in his Dissensions in Athens and Rome. The Ministers were strong enough, however, to procure the reversal of the tacking resolution: and the Bill for the appointment of the Commissioners was sent separately to the House of Lords, where, after passing all the earlier stages, it was rejected on the third reading by the Chairman's casting vote.
