A treatise on spherical trigonometry, and its application to geodesy and astronomy, with numerous examples. By John Casey.

PREFACE.
THE present Manual is intended as a Sequel to the
Author's Treatise on Plane Trigonometry, and is written
on the same plan. An examination of the Table of
Contents, or of the Index, will show the scope of the
work. It will be seen that, though moderate in size, it
contains a large amount of matter, much of which is
original.
The sources from which I have obtained information
are indicated in the text. The principal are CRELLE'S
Journal "< fir die reine und angewandte Mathematik,"
Berlin, and Nouvelles Annales de Mathématiques, Paris.
The examples, which are very numerous (over five
hundred) and carefully selected, illustrate every part
of the subject. Among them will be found some of
the most elegant Theorems in Spherical Geometry and
Trigonometry.
