8vo. xx, 188 pp. With 1 large folding copper-engraved frontisp. of mathematical instruments, 8 copper engraved plates (occasional minor closed tears, creasing to the fore-edges of the plates, couple of the joints starting in the folds). Nineteenth-century half-calf over marbled boards, marbled endpapers (hinges repaired, minor thumbing and darkening to some leaves), otherwise a VG copy. Second edition of this well-written mathematics instrument manual, incorporating a short history of 44 previous works on mathematical instruments spanning 200 years, with specific descriptions of particular instruments and their development. This work which is considered by Erwin Tomash to be "one of the most complete descriptions of a set of portable mathematical instruments extant," was expanded by over a third to detail the use of Gunners Calipers (or a Gunter's scale) for navigation purposes into a type of slide rule which were made and sold by Nairne & Blunt in London. Robertson (1716-1776) who is perhaps best remembered for his Elements of Navigation considered one of the finest English-language navigation education manuals of the 18th century, Tomash & Williams, R100; Cajori, A History of the Logarithmic Slide Rule and Allied Instruments, pp. 32-33; See: Ellerton & Clements, Samuel Pepys, Isaac Newton, James Hodgson, and the Beginnings of Secondary School Mathematics: A History of the Royal Mathematical School within Christ's Hospital, London 1673-1868 (2017), pp. 50-52, 110, 146, 218.…
