An appendix to the Answer to a book intituled A plain account of &c. [sic] the sacrament of the Lord's supper In which the Author's Prayers annex'd to the said Book are fully examin'd, in order to shew, that the Principles upon which they are form'd, are Erroneous and False, and that their many Essential defects render them utterly unfit for the use of Christians.
