Abstract
A DESCRIPTION of the sextant and the uses to which it can be applied is here given in seven chapters, of which the first describes the instrument, and shows how it may be corrected. Following, we have four chapters on different means of the determination of latitude by means of stars, showing the methods trigonometrically, and also giving examples. The accuracy of observations taken by the sextant is graphically shown by two tables, giving the latitude obtained on several successive days. Lastly, we have a description of the means by which time is determined, and also how the longitude is obtained by means of the moon and stars. Throughout the book there are numerous examples, and no pains have been spared to make it useful.
