The rule for finding Easter in the Book of Common-prayer : explain'd and vindicated against the exceptions of the late learned Dr. Wallis; ... wherein directions are given for finding the ecclesiastical new and full moon; ... Together with an appendix, shewing the true time of keeping St. Matthias's day in leap-years. - Watts, Robert (printed for J. Downing, J. Knapton, J. Wyat, R. Knaplock, J. Bonwick, H. Clements, and J. Holland, and J. Bowyer and T. Baker, 1711)
