A modest vindication of the Right Honourable Sir Gilbert Heathcote, Knight, late Lord-Mayor of the city of London. Plainly Proving, That the Act past, For Regulating the Election of Aldermen, was by a High-Church-Tack, forc'd on him, Contrary to his Inclination; and several Substantial Reasons are brought to prove, that all such Acts, Ordinances, or By-Laws, (tho' pass'd in Common-Council) yet are they contrary to Magna Charta and the Petition of Right, and cannot bind the Citizens of London.
