a| [249]-[33] pages b| abundance of manuscript illustrations, 2 volvelles, calculations & charts, 1 loose page

a| A fascinating manuscript course on navigation, astronomy, time calculations, geometry and shipping , including 2 volvelles, diagrams and other figures, partly based on the very rare first (1702) edition of De Vries's handbook, but not merely copying it.

a| The virtually unknown Klaas de Vries was a teacher of mathematics in Amsterdam.

a| Although inside it carries the title "Schatkamer ofte Konst der Stuurlieden", this manuscript doesn't merely copy the printed book: at least much of the text differs and also at least some of the tabular data, and some of the figures also have no direct equivalents in the printed book

a| Front part (249 pages) of the dos-à-dos binding contains calculations dating from 1749 onward, with the back part (33 pages) containing calculations for the years 1773 and 1774.

c| Amsterdam: 1702

a| 1 loose double sided page is dated 1786, and signed K. H. Gelling. The spine mentions "Gieters Stuurmans(schrift?)"
