Excerpt from Geometrical and Graphical Essays, Containing, a General Description of the Mathematical Instruments Used in Geometry, Civil and Military Surveying, Levelling and Perspective, 1803: With Many New Practical Problems Those who have had much occasion to use the mathematical instruments constructed to facilitate the arts of drawing, surveying, &c. have long complained that a treatise was wanting to explain their use, describe their adjustments, and give such an idea of their construction, as might enable them to select those that are best adapted to their respective purposes. This complaint has been the more general, as there are few active stations in life whose professors are not often obliged to have recourse to mathematical instruments. To the civil, the military, and the naval architect, their use must be familiar; and they are of equal, if not of more importance to the engineer, and the surveyor; they are the means by which the abstract parts of the mathematics are rendered useful in life, they connect theory with practice, and reduce speculation to use. Monsieur Bion's treatise on the construction of mathematical instruments, which was translated into English by Mr. Stone, and published in 1723, is the only regular treatise we have upon this subject; the numerous improvements that have been made in instruments since that time, have rendered this work but of little use.
