S the present Edition of Lord Bacon's Works may claim to be more correct and complete, and nearer to a standard one, than even the laft, it may be requifite to acquaint the Reader what Advantages it has to juftify fuch a Pretenfion.

These are chiefly owing to two Gentlemen, now deceased, Robert Stephens, Efq; Hiftoriographer Royal, and John Locker, Efq; Fellow of the Society of Antiquaries; both of whom had made a particular Study of Lord Bacon's Writings, and a great Object of their Industry the correcting from original or authentic Manufcripts, and the earliest and best Editions, whatever of his Works had been already published, and adding to them fuch, as could be recovered, that had never feen the Light.

Mr. Stephens dying in November, 1732, his Papers came into the Hands of Mr. Locker, whofe Death, on the 30th of May 1760, prevented the World from enjoying the Fruits of his Labours, tho' he had actually finished his Correction of the fourth Volume of Mr. Blackburne's Edition, containing the Law-Tracts, Letters, &c. After his Decease his Collections, including thofe of Mr. Stephens's, were purchased by Dr. Birch; the Use of which he is glad of this Opportunity of giving to the Public.

With regard to the Letters formerly printed of Lord Bacon, the feveral Books or Manufcripts, from which they were taken, are refpectively marked, and the Collection published by Dr. Birch in 1763 in octavo, with fome confiderable Additions by him, is added.
