Nathan Bailey, ed., An Universal Etymological English Dictionary, 10th ed. with considerable improvements (London, 1742).
Nathan Bailey (d. 1742) was a lexicographer and schoolmaster best known for his dictionaries. This dictionary is the tenth edition of his first dictionary which he published in 1721. Tenth edition was published in the same year as Bailey's death.
In 1727, Bailey published a second volume, which includes an orthographic dictionary, in which he introduced accentuation markings for the first time in a general English dictionary. Unlike a list of hard words like Robert Cawdrey's A Table Alphabeticall (1604), Bailey's dictionary includes not only hard words but also common words, scientific terms, dialect terms, and some vulgar words, with their etymology. Dr Johnson used the second edition of this dictionary as a basis of his own dictionary when compiling it. Bailey's dictionary was superseded by Johnson's, but is said to have long remained popular especially among autodidacts (see Michael Hancher's article on Bailey in the Oxford Dictionary of National Biography).
The dictionary is preceded by an introduction which is effectively a brief history of Britain and the languages spoken therein.
