33, where we have "literas longissimas quasque," being exceptional, because literæ, "an epistle," has no singular. Mr. Reid instances, indeed, from the De Officiis ii. 75, "Leges et proximæ quæque duriores," but only to propose an emendation to a senseless reading, viz., "Leges, et proxima quæque"--_i.e._, "laws, and harsher each of them than its predecessor." In the present case, he adds, "quibusque" may be used for ἑκάστοις in the sense of "each set of people," or the plural may be due merely to assimilation with "plerisque." In a note on the difficult passage, p. 41, "et minime tum quidem Gaius frater, nunc idem acerrimus," Mr. Reid, rightly, it should seem, adopts the interpretation of Madvig, Opusc., 2, 281, that _minime_ qualifies _acer_ to be supplied from "acerrimus." This sample of interpretational tact must suffice from a copious inventory; and with reference to helpful elucidation of matter and illustration of proper names, quotations, adagia, and what not, it need only be said that it is in this edition always sound and seasonable. * * * * * For the same employers, the Syndics of the Pitt Press, Mr. A. G. Peskett, M.A., of Magdalen College, has carefully edited the fourth and fifth books of Cæsar's Commentaries on the Gallic War, _Gai Juli Cæsaris De Bello Gallico Commentariorum, IV. V._ (Cambridge University Press, 1879), with a helpful commentary derived from study of German and English editors, and speculations on the topographical, geographical, and astronomical problems involved in Cæsar's account. These books, it will be remembered, contain _inter alia_ the description of Cæsar's Bridge over the Rhine, his preparations for invading Britain, his first somewhat abortive attempts, and then, after a winter in Italy and Illyricum, his maturer arrangements, and landing--not without damage to his fleet--on the shore of Britain. The second of these campaigns embraces the narrative of the treachery of Ambiorix and the utter defeat of the Romans, v. 36-7. In the fourth book, one of the most interesting problems is the construction of Cæsar's Rhine Bridge, c. 17; whether Cæsar's method of strengthening the four bearing piles with their transverse beams was (as Kraner and Heller practically agree) by four fibulæ at each junction of the beam with the piles (eight in all), or, as Cohausen believes, by two fibulæ at each end, one serving instead of cross-piece c, in fig. 1, for the beam to rest upon. Napoleon's view of the fibulaæ, given in fig. 4, p. 63, is far less tenable, and the most reasonable view is that of Heller. In c. 36, Book V., note, we have good examples of the actual words of Ambiorix to Titurius, as they may be gathered from the _oratio obliqua_ in which the historian casts them. In c. 37, it should seem that the reading _lapsi_ has less likelihood, though better authority, than "elapsi," and Napoleon's identification of the site of the battle is shown to be accurate, in a note discussing the
