Robert Darwin had given his blessing, but some obstacles still remained. Captain Robert FitzRoy was having second thoughts about sharing such close quarters for such an extended period of time. A relation of his had known the young Darwin at Cambridge. He said he wasn’t a bad sort, but did FitzRoy, the high Tory, know that he’d be rooming for two years with a Whig? And then there was the pesky problem of Darwin’s nose. FitzRoy was, as were many of his contemporaries, a believer in phrenology, which held that the shape of the skull was indicative of intelligence and character, or their absence. Some adherents expanded this doctrine to include noses. To FitzRoy, Darwin’s nose proclaimed at a glance grave deficiencies in energy and determination. After the two men had spent a little time together, though, FitzRoy, despite his reservations, decided to take a chance on the young naturalist. Darwin wrote, “I think he was afterwards well satisfied that my nose had spoken falsely.”
The Beagle’s earlier survey mission to South America had been such an unpleasant experience, the weather so consistently rotten, that her Captain had committed suicide before it was over. The British admiralty office in Rio de Janeiro turned to the twenty-three-year-old Robert FitzRoy to assume command. By all accounts he did brilliantly. He was at the helm when the Beagle resumed her survey of Tierra del Fuego and the islands nearby. After the theft of one of the Beagle’s whale boats, FitzRoy kidnapped five of the local people, who were called Fuegians by the British. When he gave up hope of recovering the boat and humanely released his hostages, one of them, a little girl they called Fuegia Basket, didn’t want to leave—or so the story goes. FitzRoy had been wondering about bringing some Fuegians back to England so they might learn its language, mores, and religion. Upon returning home, FitzRoy imagined, they would provide a liaison with other Fuegians and become loyal protectors of British interests at the strategic southern tip of South America. The Lords Commissioners of the Admiralty granted FitzRoy permission to bring the Fuegians to England. Although they were vaccinated, one died of smallpox. Fuegia Basket, a teenaged boy they called Jemmy Button, and a young man they called York Minster survived to study English and Christianity with a clergyman in Wandsworth, and to be presented by FitzRoy to the King and Queen.
Now it was time for the Fuegians—whose real names no one in England had bothered to learn—to go back; and for the Beagle to resume her survey of South America and “to determine more accurately … the longitude of a large number of oceanic islands as well as of the continents.”11 This assignment was expanded to include “observations of longitude right round the world.” She would sail down the east coast of South America, up the west coast, cross the Pacific, and circumnavigate the planet before returning home to England. Once the Beagle had been re-commissioned under Captain FitzRoy’s command, he took measures to insure that this new expedition would be very different from the previous one. Largely at his own expense, he had the 90-foot square-rigger completely re-fit. He resurfaced her hull, raised her deck, and festooned her bowsprit and her three tall masts with state-of-the-art lightning conductors. He tried to learn everything he could about weather and became one of the founders of modern meteorology in the process. On December 27, 1831, the Beagle was finally ready to sail.
On the eve of her departure, Darwin had suffered an anxiety attack and heart palpitations. There would be episodes of these symptoms, gastrointestinal distress, and profound bouts of exhaustion and depression throughout his life. Much speculation has been offered on the cause of these spells. They’ve been attributed to a psychosomatic reaction to the traumatic loss of his mother at so tender an age; to anxieties about the reactions his life’s work might elicit from God and the public; to an unconscious tendency to hyperventilate; and, strangely, although the symptoms pre-date his marriage by many years, to the pleasure he took in his beloved wife’s genius for nursing the sick. The sequence of events also makes implausible the contention that his illness was due to a South American parasite acquired during the Beagle’s voyage. We simply do not know. His symptoms caused this explorer to be mainly housebound for the last third of his life.
