THE following work is designed principally for the use of those who desire to pursue the study of Astronomy as a branch of liberal education. To acilitate its use by students of different grades, the subject-matter is divided into two classes, distinguished by the size of the type, and the volume is thus made to contain two courses.

The portions in large type form a complete course for the use of those who desire only such a general knowledge of the subject as can be acquired without the application of advanced mathematics. It is believed that this course can be mastered by persons having at command only those geometrical ideas which are familiar to most intelligent students in our advanced schools ; though sometimes, especially in the earlier chapters, a knowledge of elementary trigonometry and physics will be found conducive to a full understanding of a few details.
