A form of prayer with fasting, to be us'd yearly upon the 30th of January, : being the day of the martyrdom of the blessed King Charles the First: to implore the mercy of God, that neither the guilt of that sacred and innocent bloud, nor those other sins, by which God was provoked to deliver up both us, and our King into the hands of cruel and unreasonable men, may at any time hereafter be visited upon us, or our posterity. : By His Majesties special command.
