Such, from my arrival at Lausanne, during the first eighteen or twenty months (July 1753--March 1755), were my useful studies, the foundation of all my future improvements. But every man who rises above the common level has received two educations: the first from his teachers; the second, more personal and important, from himself. He will not, like the fanatics of the last age, define the moment of grace; but he cannot forget the aera of his life, in which his mind has expanded to its proper form and dimensions. My worthy tutor had the good sense and modesty to discern how far he could be useful: as soon as he felt that I advanced beyond his speed and measure, he wisely left me to my genius; and the hours of lesson were soon lost in the voluntary labour of the whole morning, and sometimes of the whole day. The desire of prolonging my time, gradually confirmed the salutary habit of early rising, to which I have always adhered, with some regard to seasons and situations; but it is happy for my eyes and my health, that my temperate ardour has never been seduced to trespass on the hours of the night. During the last three years of my residence at Lausanne, I may assume the merit of serious and solid application; but I am tempted to distinguish the last eight months of the year 1755, as the period of the most extraordinary diligence and rapid progress. In my French and Latin translations I adopted an excellent method, which, from my own success, I would recommend to the imitation of students. I chose some classic writer, such as Cicero and Vertot, the most approved for purity and elegance of style. I translated, for instance, an epistle of Cicero into French; and after throwing it aside, till the words and phrases were obliterated from my memory, I re-translated my French into such Latin as I could find; and then compared each sentence of my imperfect version, with the ease, the grace, the propriety of the Roman orator. A similar experiment was made on several pages of the Revolutions of Vertot; I turned them into Latin, returned them after a sufficient interval into my own French, and again scrutinized the resemblance or dissimilitude of the copy and the original. By degrees I was less ashamed, by degrees I was more satisfied with myself; and I persevered in the practice of these double translations, which filled several books, till I had acquired the knowledge or both idioms, and the command at least of a correct style. This useful exercise of writing was accompanied and succeeded by the more pleasing occupation of reading the best authors. The perusal of the Roman classics was at once my exercise and reward. Dr. Middleton's History, which I then appreciated above its true value, naturally directed the to the writings of Cicero. The most perfect editions, that of Olivet, which may adorn the shelves of the rich, that of Ernesti, which should lie on the table of the learned, were not in my power. For the familiar epistles I
