THE READER of this volume is expected to possess such knowledge of Mathematics as may be gained by studying the Elements of Euclid and Algebra, together with a rudimentary acquaintance with the geometry of Planes and Spheres.

While the book is mainly intended for beginners, yet it is believed that more advanced students may find portions of it useful. This will perhaps be especially the case in the last chapter, where a somewhat extended account is given of the important constants of Astronomy, with references to the original sources of information.

Many of the illustrations have been taken from Delaunay's 'Cours Elementaire d' Astronomic,' and a few from Secchi's ' Le Soleil,' from Guillemin's ' Le Ciel,' and other sources. In the last chapter extensive use has been made of Houzeau's * Repertoire des Constantes Astronomiques.'
