This edition of Caesar's Commentaries, intended to follow the Latin Reader, aims to introduce the student to an appreciative study of Latin authors. The text is the result of a careful collation of the several edi tions most approved by European scholars. The notes are intended to guide the faithful efforts of the learner, and to furnish him such collateral information as will enable him to understand the stirring events recorded in the Commentaries, and such special aid as will enable him to surmount real difficulties of construction and idiom. They will thus, it is hoped, render an acceptable service both to the instructor and the learner, by lightening the burden of the one, and by promoting the progress of the other. The dictionary has been prepared with special reference to the wants of the student.
