First, with as great Means, Care, and Industry, as possibly I could use, so many of the old Statutes heretofore printed in the English Tongue, made and published in the Reigns of the first Ten Kings (accounting from 9 of Hen. III. unto 1 of Ric. III. inclusive), as be chiefly in Use and Practice, and which are the Foundation of Proceedings both legal and judicial, have been by me truly and sincerely examined by the original Records thereof remaining in the Tower of London; and the Residue with the Register of Writs, being the most antient Book of the Law, the old and new Natura Brevium, the Books of Entries, the Books of Years, and Terms of the Law; the best approved, printed, and written Books; and by all such other Circumstances as might best give Probability of Truth unto the Learned. By reason whereof, the foresaid Defects, Imperfections, and Emblemishments being reformed in this Edition, as it is a Collection of the most usual Laws, gathered from out the grand Codex of all the Statutes, so it may serve as a Correction to the former Impressions.
