The expedition next sent out under the command of Captain Dumont d'Urville was merely intended by the minister to supplement and consolidate the mass of scientific data collected by Captain Duperrey in his voyage from 1822 to 1824. As second in command to Duperrey, and the originator and organizer of the new exploring expedition, D'Urville had the very first claim to be appointed to its command. The portions of Oceania he proposed to visit were New Zealand, the Fiji Islands, the Loyalty Islands, New Britain, and New Guinea, all of which he considered urgently to demand the consideration alike of the geographer and the traveller.

Caillié, who was born in 1800, in the department of the Seine et Oise, had only an elementary education; but reading Robinson Crusoe had fired his youthful imagination with a zeal for adventure, and he never rested until, in spite of his scanty resources, he had obtained maps and books of travel. In 1816, when only sixteen years old, he embarked for Senegal, in the transport-ship La Loire.
Although John Lewis Burckhardt was not English, for he was a native of Lausanne, he must none the less be classed among the travellers of Great Britain. It was owing to his relations with Sir Joseph Banks, the naturalist who had accompanied Cook, and Hamilton, the secretary of the African Association, who gave him ready and valuable support, that Burckhardt was enabled to accomplish what he did.
