Alexander Ewing's Synopsis was a popular text in Scotland, and throughout Great Britain, and had numerous reprintings in the 1790s alone. In this THIRD EDITION, Ewing notes in his Preface that due to the "favourable reception" of the previous two editions, that he has made "this third edition still more compleat than either of them, by several useful additions" making this edition the more sought-after by practitioners of the day. Ewing’s Synopsis has been cited by scholars in later centuries as being instrumental in several areas – particularly as it has been referenced as one of the standards of mathematics that influenced the practice of navigation in Britain in the period some historians celebrate as the birth of scientific navigation. His chapter on "Gunnery," which discusses the art of aiming and the mathematics of projectiles, has been cited for its contribution to the study of artillery and warfare. Ewing was not affiliated with Edinburgh University, but was rather one of the "private teachers," of whom there seem to have been a considerable number in the University towns during the 1700’s. Alexander Ewing died in 1804 and was interred in the family vault in Saint Cuthbert’s Churchyard, Edinburgh. His obituary was carried in the The Scots Magazine, and Edinburgh Literary Miscellany Vol 66 (LXVI), Sept. 1804.…
