----- 关于导航和航海天文学的论述,包括指南针偏差理论,准备用作美国的教科书
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.
