An essay upon publick credit : being an enquiry how the publick credit comes to depend upon the change of the ministry, or the dissolutions of Parliaments; and whether it does so or no. With an argument, proving that the publick credit may be upheld and maintain'd in this nation; and perhaps brought to a greater height than it ever yet arriv'd at; tho' all the changes or dissolutions already made, pretended to, and now discours'd of, shou'd come to pass in the world.. / Defoe, Daniel, 1661?-1731 [Attributed: Oxford, Robert Harley, Earl of, 1661-1724]
