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 #251797

In this volume, the endeavor has been made to place under one cover the allied subjects of Navigation, Theory of Com pass 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.
