The new book of knowledge; or, Young man's best instructor in the arts and sciences. [electronic resource] : Part I. The theory and practice of arithmetic, vulgar and decimal; the arithmetic of algebra by transposition introduced, as it gives rules to the accomptant; annuities for time; the principles of Mr. Demeivre, Mr. Simpson, and of the author, in estimating annuities for single lives, considered from the equity in sinking money. Digested into systems. Part II. An extensive course of geometry; mensuration; an introduction to gauging and surveying; plain trigonometry; the astronomical principles of geography; the construction and use of maps; the mensuration of the globes of the solar system, and of their orbits; the estimations of artificers; and the debates of the globes concerning the earth's two motions to effect the seasons, &c. Expressly designed to remove that general complaint of not effectually instructing youth, while at school, in what may be of importance in their future stations, and enlarging their narrow conceptions and scanty views of nature. The various subjects are so digested and expressed as to assist the master, and to ground, forward, and encourage the scholar, and to make him of immediate use when he is put to the test. With eight copper-plates. To which is prefixed, a letter on education.
