The marrow of the mathematicks, made plain and easie to the understanding of any ordinary capacity. [electronic resource] : Containing the doctrines of arithmetick, geometry, astronomy, gauging, the use of the sector, surveying, dialling, and the art of navigation, &c. illustrated with several cuts for the better explanation of the whole matter. After a new, compendious, easy method. To which is added, measuring surfaces and solids, such as plank, timber, stone, &c. joiners, carpenters, bricklayers, glasiers, painters and paviers work: each proposition being wrought vulgarly, decimally, practically and instrumentally. With a small tract of gauging wine, ale, or malt, without inches, or division, by which any one may gauge ten backs, or floors of malt, in the same time another shall gauge one, by the way now used: altogether new.
