Jenny was outraged by the introduction of the prayer book and she lifted the creepie on which she was sitting and threw it at the dean's head. As she threw the stool she shouted, 'Deil colic the wame o’ ye! Oot thou fause thief! Dost thou say the mass at my lug?' (The devil give a colic to your stomach! Out you false thief! Dare you say the mass at my ear?).
This led to general unrest in the city and elsewhere in Scotland and eventually to the signing of the National Covenant in February 1638. The covenant rejected any attempt to introduce innovations like the Prayer Book that had not first been subject to the scrutiny of Parliament and the General Assembly of the Church of Scotland.
