Excerpt:

I have no remembrance of the time when I began to learn Greek. I have been told that it was when I was three years old. My earliest recollection on the subject, is that of committing to memory what my father termed Vocables, being lists of common Greek words, with their signification in English, which he wrote out for me on cards. Of grammar, until some years later, I learnt no more than the inflexions of the nouns and verbs, but, after a course of vocables, proceeded at once to translation; and I faintly remember going through Æsop’s Fables, the first Greek book which I read. The Anabasis, which I remember better, was the second. I learnt no Latin until my eighth year. At that time I had read, under my father’s tuition, a number of Greek prose authors, among whom I remember the whole of Herodotus, and of Xenophon’s Cyropædia and Memorials of Socrates; some of the lives of the philosophers by Diogenes Laertius; part of Lucian, and Isocrates Ad Demonicum and Ad Nicoclem. I also read, in 1813, the first six dialogues (in the common arrangement) of Plato, from the Euthyphron to the Theætetus inclusive: which last dialogue, I venture to think, would have been better omitted, as it was totally impossible I should understand it. But my father, in all his teaching, demanded of me not only the utmost that I could do, but much that I could by no possibility have done.
