Original sewing with back wrapper only small chip at outer edge and stained first two leaves detached; engraved vignette title page waterstained and badly chipped with some loss to imprint. Still a remarkable survival of a rare and fragile book. The Second edition with an Appendix" Engraved title page chipped and defective 2 iii 1 86 pp. 1 vols. Small 4to. A Rare Manual of Navigation 1778. In his modest introduction Falck gives credit to the likes of Cornelius Douwes and Richard Harrison for inventing the method of determining latitude at sea by the use of solar tables. The appendix is a "Description of the Principles and Use of a plain Hadley's Quadrant and how to apply it in real Practice for taking a correct Altitude."<br/><br/>This second edition is much rarer than the first which was published in 1771. It is also a good fifteen pages longer. Falck would have been considerably buoyed by the involvement of Mount and Page one of the foremost publishers of maritime material in eighteenth century London. Especially as the first edition was published at his own expence. ESTCT 59664 British Library only; OCLC: 84682637 2 copies in US printed for J. Mount, T. Page and W. Mount unknown books
