Geometrical and graphical essays, containing a general description of the mathematical instruments used in geometry, civil and military surveying, levelling, and perspective; with many new practical problems
A London technical manual of 1803 by instrument maker George Adams, revised by William Jones, describing mathematical instruments for geometry, surveying, levelling and perspective, aimed at surveyors, engineers and students. The engraved plates give measured views of brass apparatus—graduated circles, tripod stands, telescopic sights—drawn in fine outline with letter keys, useful for instrument silhouettes, dial and scale detail, and annotated diagram layouts.
