### John Morison copybook, 1764-1772

1 volume

John Morison of Windham, New Hampshire, compiled this mathematical cypher book, containing extensive notes and practice problems on sailing, surveying, trigonometry, accounting, weights and measures, arithmetic, algebra, fractions, decimals, geometry, geodesia, and navigation. Many of the signatures are of different-size paper and stitched together using different thread. The final signature is upside down from the rest of the volume and contains penmanship practice, poetry, a song, scattered family names, miscellaneous figures, and drawings (including a windmill).
