Treatise on Navigation and Nautical Astronomy, Including the Theory of Compass Deviations, Prepared for Use as a Text-Book at the U. S

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. 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.
