Yet Boswell's stock of learning was small. 'I have promised,' he writes in 1775, 'to Dr Johnson to read when I get to Scotland; and to keep an account of what I read. He is to buy for me a chest of books, of his choosing, off stalls, and I am to read more, and drink less--that was his counsel.' The death of his wife forces the confession, 'how much do I regret that I have not applied myself more to learning,' and he acknowledges to their common friend Langton that, if Johnson had said that Boswell and himself did not talk from books, this was because he had not read books enough to talk from them. In his manuscripts there are many misspellings. He assigns to Terence a Horatian line and, in a letter to Garrick, quotes as Horatian the standard _mens sana in corpore sano_ of Juvenal. More strange is his quoting in a note an illustration of the phrase 'Vexing thoughts,' without his being apparently aware that the words are by Rous of Pembroke, the Provost of Eton, whose portrait in the college hall he must often have seen, the writer of the Scottish Metrical Version of the Psalms. Yet his intellectual interests were keen. Late in life he has 'done a little at Greek; Lord Monboddo's _Ancient Metaphysics_ which I am reading carefully helps me to recover the language.' He has his little scraps of irritating Latinity which he loves to parade, and when he dined at Eton, at the fellows' table, he 'made a considerable figure, having certainly the art of making the most of what I know. I had my classical quotations very ready.' Besides, the easy allusiveness of Boswell to books and to matters beyond the scope of general readers, his interest in all things going forward in the Johnsonian circle, his shewing himself in some metaphysical points--predestination, for example--fully a match for Johnson, and his own words in the _Journal_--'he had thought more than anybody supposed, and had a pretty good stock of general learning and knowledge'--all conspire to shew that, if he had no more learning than what he could not help, James Boswell was altogether, as Dominie Sampson said of Mannering, 'a man of considerable erudition despite of his imperfect opportunities.'
