'A Paper On Terrestrial Magnetism,' designed for the use of surveyors, offers a detailed exploration into the principles and practical applications of geomagnetism. Authored by Elihu Thayer Quimby, this work provides essential knowledge for accurately conducting land surveys by understanding magnetic variations. The book covers the fundamentals of terrestrial magnetism, explaining the concepts of magnetic declination and inclination and their impact on surveying practices. Surveyors will find detailed instructions on using magnetic instruments to measure angles and directions and compensate for magnetic disturbances. The text emphasizes the importance of understanding and accounting for local magnetic anomalies to ensure precise measurements. This book is a valuable historical resource for anyone interested in the early methods of land surveying and the scientific understanding of Earth’s magnetic field.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
