Note from 'Books Read and Study Made' chapter from 'Memoirs Of My Life And Writing' by Gibbon

JOURNAL, December 1755. — In finishing this year, I must remark how favourable it was to my studies. In the space of eight months, from the beginning of April, I learnt the principles of drawing; made myself complete master of the French and Latin languages, with which I was very superficially acquainted before, and wrote and translated a great deal in both; read Cicero's Epistles ad Familiares, his Brutus, all his Orations, his Dialogues de Amicitiâ, and De Senectute ; Terence, twice; and Pliny's Epistles. In French, Giannone's History of Naples, and 1'Abbé Bannier's Mythology, and M. De Boehat's Mémoires sur la Suisse, and wrote a very ample relation of my tour. I likewise began to study Greek, and went through the Grammar. I began to make very large collections of what I read. But what I esteem most of all, from the perusal and meditation of De Crousaz's Logic, I not only understood the principles of that science, but formed my mind to a habit of thinking and reasoning I had no idea of before.
