A Treatise On Navigation And Nautical Astronomy Including The Theory Of Compass Deviations PDF Download

Excerpt from A Treatise on Navigation and Nautical Astronomy, Including the Theory of Compass Deviations, Prepared for Use as a Text-Book at the U. S: Naval Academy In this volume, the endeavor has been made to place under one cover the allied subjects of Navigation, Theory of Compass Deviations, and Nautical Astronomy; and, though the book has been written primarily for the use of midshipmen, it is believed that the various subjects have been so presented that any zealous student with only a slight knowledge of trigonometry may be able to master any method given. An effort has been made to include in this work not only the results of a large practical experience at sea, but information gleaned, during tours of duty in this department, from a study of the best English and American authorities. Much attention has been given to a description of the various navigational instruments, their uses, and errors; and to the principles involved in the construction of charts as well as to an account of the work usually performed on them. The Theory of the Deviations of the Compass has been presented in the popular way for the practical man, and from a mathematical standpoint for more advanced students. In Part II enough of Theoretical Astronomy has been incorporated to enable any one without a previous knowledge of that science to pursue the study of the practical part of Nautical Astronomy.
