MS note in hand of G. M. Trevelyan below the letter: 'Letter of (Sir) Charles Trevelyan to Sir Walter Trevelyan of Wallington about Macaulay's accumulation of material for his History of England. The first one (1840) shows what the design was in his head at that time'.
A note at the end of the letter in pencil asks 'Did he [Charles Trevelyan] expect to go back to India?', and a note in pen replies 'yes'; another note in pen records 'On Jan. 20th became assistant Sec. Treasurer'.
Macaulay, Thomas Babington (1800-1859), 1st Baron Macaulay, historian, essayist, and poet
