Practical geometry, : in two parts: the first, shewing how to perform the four species of arithmetick, (viz. addition, subtraction, multiplication, and division,) together with reduction, and the rule of proportion in figures. The second, containing a hundred geometricall questions, with their solutions and demonstrations, some of them being performed arithmetically, and others geometrically, yet all without the help of algebra. A worke very necessary for all men, but principally for surveyors of land, engineers, and all other students in the mathematicks. /
