PREFACE
In the following pages, it has been my object to give a brief and clear account of those portions of Astronomy which can be dealt with, with the help of elementary Mathematics. In the selection of subject-matter and its treatment, I have been guided by my experience as a teacher of Astronomy, so that the book will, I trust, be found to meet the requirements of students by stimulating thought and ensuring scientific accuracy.
