Practical measuring made easy to the meanest capacity, by a new set of tables : Which shew at sight, the solid or superficial content (and consequently the value) of any piece or quantity of timber, stone, board, glass, &c. used in building, &c. Also, the solid content (and consequently the value) of all kinds of squared or round timber, whether it be standing or felled. Contrived to answer all the occasions of gentlemen and artificers, far beyond any thing yet extant, the contents being given in feet, inches, and twelfth parts of an inch. With a preface; shewing the convenience and excellence of this new method, and demonstrating, that whoever ventures to rely upon those obsolete tables and directions published by Isaac Keay, is liab[l]e to be deceived (in common cases) 10s. in the pound. By E. Hoppus, surveyor to the corporation of the London assurance. The fourth edition; together with the late addition of the quarters of a foot in the length, to the table of solid measure; and of the inches and quarters of an inch in the length, to the table of superficial or flat measure. Also, some very curious observations concerning the measuring of timber by several dimensions. Communicated by one of His Majesty's purveyors.
