Die Mercurii, 19 July, 1643.  
THE Lords and Commons assembled in Parliament, out of the deep sense of God's heavy wrath now upon this kingdom, and more particularly manifested by the late discomfeiture of the Forces, both in the North and in the West; Have for themselves resolved to set apart and keep, and do ordain, and command▪ That Friday the 21. of this present July, 1643. be set apart and kept as a day of public and extraordinary humiliation by Prayer and Fasting, throughout the Cities of London and Westminster, and the Suburbs, and places adjacent, within the bills of Mortality; That every soul may bitterly bewail his own sins, and the sins of the whole Nation, And cry mightily to God for Christ his sake, that he will be pleased to turn from the fierceness of his wrath, and heal the Land. And the Lord Mayor of the City of London, is hereby required to give present order for the due performance of this Order.  
To the Gentleman▪ usher, or his Deputy, to be delivered to the Lord Mayor of the City of London.  
Jo. Browne Cleric. Parliamentorum.
