2nd edition in Dutch, Amsterdam: Gerard Hulst van Keulen, [1789], [6] 1-214 [10] pp., signatures [*]1-3 A-2E4, [*]1=half-title, 72 engraved charts on 19 folding sheets, list of charts in contemporary manuscript to rear free endpaper, modern bookplate contemporary red sheep backing patterned paper boards, spine rubbed, 4to (25 x 20 cm).

One copy only of this edition in libraries world-wide, at the University of Amsterdam (their cataloguing supplying the date 1789), and four of the 1745 edition (BayerischeStaatsbibliothek, Bibliothèque nationale de France, Leiden, and the Royal Library of the Netherlands) our copy seems to conform to that held by the University of Amsterdam; it is probable that van Keulen has discarded the dedication leaf to the by then deceased Baron van Botzelaer, and reset the rest of the preliminaries as a result.
