' [Johnson having asked for details about Lord Peterborough] "But, (said his Lordship [Lord Eliot,) the best account of Lord Peterborough that I have happened to meet with, is in "Captain Carleton's Memoirs". Carleton was descended of an ancestor who had distinguished himself at the siege of Derry. He was an officer; and, what was rare at that time, had some knowledge of engineering". Johnson said, he had never heard of the book. Lord Eliot had it at Port Eliot; but, after a good deal of enquiry, procured a copy in London, and sent it to Johnson, who told Sir Joshua Reynolds that he was going to bed when it came, but was so much pleased with it, that he sat up till he had read it through, and found in it such an air of truth, that he could not doubt of its authenticity; adding, with a smile, (in allusion to Lord Eliot's having recently been raised to the peerage,) "I did not think a [italics] young Lord [end italics] could have mentioned to me a book in the English history that was not known to me".'
