Wherein every thing that is useful and curious in that art, is fully considered and explained. Particularly three new and very concise methods for determining the areas of right-lined figures, arithmetically or by calculation, as well as the geometrical ones heretofore treated of. The whole illustrated with copper-plates. By Robert Gibson; teacher of the mathematics. With alterations and amendments, adapted to the use of American surveyors.
