[Mercantile arithmetic]
This manuscript arithmetic from 1707 is a mercantile teaching book of worked sums on trade goods such as nobles, pennies, beer, barrels of ale, Holland cloth and nails, probably written for merchants or apprentices. Its pages show hand-ruled red-line boxes and diagrams with dense columns of figures in brown ink, offering a designer a sense of early handwritten layout, boxed grids and ruled frames.
