John Murray III (1808–1892) continued the business and published Charles Eastlake's first English translation of Goethe's Theory of Colours (1840), David Livingstone's "Missionary Travels" (1857), and Charles Darwin's "Origin of Species" (1859). Murray III contracted with Herman Melville to publish Melville's first two books, "Typee" (1846) and "Omoo" (1847) in England; both books were presented as nonfiction travel narratives in Murray's "Home and Colonial Library" series, alongside such works as the 1845 second edition of Darwin's "Journal of Researches" from his travels on . John Murray III also started the "Murray Handbooks" in 1836, a series of travel guides from which modern-day guides are directly descended. The rights to these guides were sold around 1900 and subsequently acquired in 1915 by the Blue Guides.
