1785. First. hardcover. A unique book, circa 1785. 116 pages, 8 x 6.5 inches, bound in well-worn vellum (first signature re-attached). Entirely handwritten in the excellent decorative penmanship of the time. The book consists of six sections, each a mathematical lesson (Profit and Loss; Fellowship with Time; Alligation Medial; Position; Double Position; Exchange). For each lesson there are difficult word problems followed by the involved mathematics required to solve the problem, along with the final answer. Very good condition considering its age. very good.
