Surveying and Levelling Instruments, Theoretically and Practically Described: For Construction, Qualities, Selection, Preservation, Adjustments, and ... Engineers and Surveyors
Excerpt from Surveying and Levelling Instruments, Theoretically and Practically Described
Notes were taken for many years before the production of this work Of queries that came before the author for reply relative to functional parts Of surveying instruments. These bore most frequently reference to optical and magnetic subjects, and to the qualities and action Of spirit level tubes, also occasionally to graduation and the qualities Of clamp and tangent motions. It was therefore thought that it would be useful to give notes upon these subjects in detail as far as possible in the early chapters. As the work proceeded it was found that this plan saved much space in avoiding the necessity for separate descriptions when parts Of complex instruments were afterwards described.
