With ownership inscription on the title page ‘Peter Weston 1795’. The ‘English Pilot’ was the first completely English sea atlas and the ‘West-India Navigation’ the first English sea atlas of the Americas. Its influence was enormous and it dominated its market being issued in at least 37 editions from 1689 to 1794. It was the ‘bible’ for mariners trading in American waters. This edition of 1763 was the last that bore the imprint of William Mount who retired in the same year, he died in 1769. The 1760’s was a period of change for the atlas in that some maps were retired and new ones introduced. Using Verner’s collations four charts appear to be new to this edition. The only other example cited is at Yale University. In studying previous editions it appears that 3 maps were dropped, two of them are old plates firsst issued in 1721 and a version of the even earlier Edmund Halley plate of the Atlantic Ocean. All editions of the ‘English Pilot’ are rare, and because of the demand for North American material the ‘Fourth Book’ particularly so. Verner ‘Bibliographical Note’ to the Facsimile of the 1689 edition.
