nished his prescribed
course.

The METHOD of treatment corresponds with the object of the book.
Truth, accuracy, and order have been aimed at first, with clearness
and freedom from ambiguity.

In AMOUNT, the work has been adjusted as closely as possible to the
prevailing courses of study in our colleges. The fine print may be
omitted from the regular lessons and used as collateral reading. It is
important to anything like a complete view of the subject, but not
essential to a course. Some entire chapters can be omitted, if
necessary.

NEW TOPICS, as indicated above, have received a full share of
attention, and while the book makes no claims to novelty, the name of
the author is a guarantee of much originality both of matter and
manner.

The book will be found especially well adapted for high school and
academy teachers who desire a work for reference in supplementing
their brief courses. The illustrations are mostly new, and prepared
expressly for this work. The tables in the appendix are from the
latest and most trustworthy sources. A very full and carefully
prepared index will be found at the end.

The eminence of Professor Young as an original investigator in
astronomy, a lecturer and writer on the subject, and an instructor of
college classes, and his scrupulous care in preparing this volume, led
the publishers to present the work with the highest confidence; and
this confidence has been fully justified by the event. More than one
hundred colleges adopted the work within a year from its publication.

This volume is a new work, and not a mere abridgment of the author's
_General Astronomy_. Much of the material of the larger book has
naturally been incorporated in this, and many of its illustrations are
used; but everything has been worked over, with reference to the high
school course.

Special attention has been paid to making
