Mathematical Treasure: David Gregory's Practical Geometry

Some Latin lecture notes by Scottish mathematician David Gregory (1659-1708) were translated after his death, resulting in the posthumous publication of A Treatise of Practical Geometry in 1745. The title page is shown below.

The applied nature of this work is reflected in the plates of figures supporting the textual discussion. Note the use of particular measuring instruments in the diagrams below.
