Book excerpt: This is the second and final volume of manuscripts by or relating to Thomas Robert Malthus (1766–1834) that are now held at Kanto Gakuen University in Japan. Volume I contains 75 items of correspondence, while Volume II contains transcriptions of further original manuscripts, including: four of Malthus' sermons; his diary of a tour of the Lake District; an extensive set of calculations in the bullion trade, suggesting that he was giving serious thought to becoming a bullion trader on his own account; lecture notes on European history from the fifth to the tenth century; his wife's diary of their holiday in Scotland in 1826 and an essay on foreign trade. These previously unknown and unpublished manuscripts promise insights into his intellectual development and the events and circumstances of his life, as well as glimpses of the lifestyle of his wider family and contemporaries.
