During Charles Darwin's 1831–6 voyage on the Beagle, his on-board library included 'Cook's voyages' (the edition is not specified). This illustrated 1821 edition, in seven volumes, is representative of the versions available in the early nineteenth century. Volumes 1 and 2 cover the first Pacific voyage of James Cook (1728–79), the object of which was to observe the 1769 transit of Venus from Tahiti. The text replicates the version published in 1773 by John Hawkesworth (1715–73) as part of a collection of 'Voyages … in the Southern Hemisphere', which interwove Cook's account with botanical and ethnographical notes by the ship's naturalist, Sir Joseph Banks (1743–1820). The journals were only published separately much later: Cook's in 1893 (ed. Wharton) and Banks' in 1896 (ed. Hooker); both are also available. Volume 2 focuses on New Zealand, Australia, and the explorers' return via Indonesia.
