“No labor has been spared in condensing into the smallest compass the
information at the author’s disposal, and in endeavoring to render the
treatment of the subject simple and clear. If the student’s path has
in any degree been rendered easy, it is because a good deal of labor
has been expended on the roadway.”--_Extract from Preface._
