MACMILLAN'S CLASSICAL SERIES, for COLLEGES and SCHOOLS, being select portions of Greek and Latin authors, edited, with Introductions and Notes at the end, by eminent scholars. The series is designed to supply first rate text-books for the higher forms of Schools, having in view also the needs of Candidates for public examinations at the Universities and elsewhere. With this object the editors have endeavoured to make the books as complete as possible, passing over no difficulties in the text, whether of construction or of allusion, and adding such information on points of Grammar and Philology as will lead students on in the paths of sound scholarship. Due attention moreover is paid to the different authors, in their relation to literature, and as throwing light upon ancient history, with the view of encouraging not only an accurate examination of the letter, but also a liberal and intelligent study of the spirit of the masters of Classical Literature. The books are clearly printed in fcap. 8vo., and uniformly bound in neat red cloth. The following volumes are ready : CICERO—THE SECOND PHILIPPIC ORATION. From the German of Karl Halm.
