This collection of documents mainly consists of manuscripts held in the National Records of Scotland and the National Library of Scotland. The records all relate to Catholics in Scotland in the 1720s and 1730s and to the state of the Scottish Mission in that period. All but one were penned by Church of Scotland ministers and Royal Bounty catechists. The remaining item is a memorial to Propaganda Fide written by a Scottish Catholic. These riveting accounts shed valuable light on the Scottish Mission and on the contrasting perceptions Protestants and Catholics had of the `State of Popery' in the early eighteenth century.
