The Appendices (pp. 274-363) may be referred to when a boy finds himself in doubt about the value of a Conjunction (I.), the force of a Prefix (II.), the meaning of a Suffix (III.), the Life and Times of his Author (VI.), or the historical significance of a date (VII.). In Appendix V. a Demonstration is given to show how a boy, after sufficient practice in translation by the help of analysis, may to some extent learn to think in Latin, and so to follow the Latin order in arriving at the thought. The important question of what maps should accompany the book will be best solved by providing each boy with a copy of Murray’s Small Classical Atlas, edited by G. B. Grundy, which will be found to be admirably adapted to the purpose. By the kindness of Mr. John Murray, two plans (Dyrrachium and Pharsalus), not at present included in the Atlas, have been specially drawn to illustrate passages on pp. 216 and 218, and are placed opposite the text. As far as possible I have acknowledged my indebtedness to the Editors whose editions of the classics have been consulted. For the historical explanations I am under special obligation to the histories of Ihne and Mommsen, to the ‘Life of Cicero’ by the Master of Balliol, and to the ‘Life of Caesar’ by Mr. Warde Fowler. I have also to thank Messrs. Macmillan for allowing me to quote from Dr. Potts’ ‘Aids to Latin Prose,’ and from Professor Postgate’s _Sermo Latinus_. For the prose passages the best texts have been consulted, while for Livy, Weissenborn’s text edited by Müller (1906) has been followed throughout. As regards the verse passages, the text adopted is, wherever possible, that of Professor Postgate’s recension of the _Corpus Poetarum Latinorum_. For the Short Lives I have found useful ‘The Student’s Companion to Latin Authors’ (Middleton and Mills), but I owe much more to the works of Teuffel, Cruttwell, Sellar, Tyrrell, and Mackail. The Head Master of Eton, besides expressing his approval of the book, has kindly offered to write an Introductory Note. He has also given me an exceptional opportunity of testing more than half the historical passages by allowing them to be used in proof, until the book was ready, for the weekly unseen translation in the three blocks of fifth form, represented by the letters, B, C, D. The criticisms and suggestions made by Classical Masters at Eton, who have used the passages week by week, have been very valuable, and, in particular, my thanks are due to Mr. Impey, Mr. Tatham, Mr. Macnaghten, Mr. Wells, and Mr. Ramsay. My thanks are also due to the Lower Master, Mr. F. H. Rawlins, for kindly reading the MS. of the Introduction, Demonstrations, and Appendices I.-IV., and for giving me the benefit of his wide experience. To my brother-in-law, Mr. A. M. Goodhart, I owe it that I undertook to write the book; without his advice it would never have seen the light, and he has given me most valuable help and encouragement at every stage.
