 Apart from that a large part of the north and southeast of the country remained unvisited.During his stay he bought many Spanish books, particularly of literature, artistic treatises, topography, local histories and of local saints.He continued to procure such items after his return home, notably at the Heber (1834–1836), W. B. Chorley (1846) and Riego (1847) sales, which helped to augment his knowledge of those areas he did not visit.
