(During Beagle's first voyage, Captain <a href="/wiki/Pringle_Stokes" title="Pringle Stokes">Pringle Stokes</a> had died by suicide. The expedition's leader appointed Beagle's 1st Lieutenant, W. G. Skyring, as her acting commander. Roughly three months later, Admiral Otway decided to give Beagle to his flag lieutenant, FitzRoy.) FitzRoy had thought of the advantages of having someone onboard who could investigate <a href="/wiki/Geology" title="Geology">geology</a>, and sought a <a href="/wiki/Natural_history" title="Natural history">naturalist</a> to accompany them as a <a href="https://en.wiktionary.org/wiki/supernumerary" class="extiw" title="wikt:supernumerary">supernumerary</a>. At the age of 22, the graduate <a href="/wiki/Charles_Darwin" title="Charles Darwin">Charles Darwin</a> hoped to see the tropics before becoming a <a href="/wiki/Parson" title="Parson">parson</a>, and accepted the opportunity. He was greatly influenced by reading <a href="/wiki/Charles_Lyell" title="Charles Lyell">Charles Lyell</a>'s <a href="/wiki/Principles_of_Geology" title="Principles of Geology">Principles of Geology</a> during the voyage. By the end of the expedition, Darwin had made his name as a geologist and <a href="/wiki/Fossil" title="Fossil">fossil</a> collector, and the publication of his journal (later known as <a href="/wiki/The_Voyage_of_the_Beagle" title="The Voyage of the Beagle">The Voyage of the Beagle</a>) gave him wide renown as a writer. Beagle sailed across the Atlantic Ocean, and then carried out detailed <a href="/wiki/Hydrographic_survey" title="Hydrographic survey">hydrographic surveys</a> around the coasts of southern South America, returning via <a href="/wiki/Tahiti" title="Tahiti">Tahiti</a> and Australia, after having <a href="/wiki/Circumnavigation" title="Circumnavigation">circumnavigated</a> the Earth. The initial offer to Darwin told him the voyage would last two years; it lasted almost five. Darwin spent most of this time exploring on land: three years and three months land, 18 months at sea.<a href="#cite_note-intro-1">[1]</a> Early in the voyage, Darwin decided that he could write a geology book, and he showed a gift for theorising. At <a href="/wiki/Punta_Alta" title="Punta Alta">Punta Alta</a> in Argentina, he made a major find of gigantic fossils of extinct mammals, then known from very few specimens. He collected and made detailed observations of plants and animals. His findings undermined his belief in the doctrine that <a href="/wiki/Species#Fixed_species" title="Species">species are fixed</a>, and provided the basis for ideas which came to him when back in England, leading to his theory of <a href="/wiki/Evolution" title="Evolution">evolution</a> by <a href="/wiki/Natural_selection" title="Natural selection">natural selection</a>. <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Aims_of_the_expedition">Aims of the expedition</h2>[<a href="/w/index.php?title=Second_voyage_of_HMS_Beagle&action=edit&section=1" title="Edit section: Aims of the expedition">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:British_Museum_Marine_Chronometer.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/c/ce/British_Museum_Marine_Chronometer.jpg/170px-British_Museum_Marine_Chronometer.jpg" decoding="async" width="170" height="281" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/c/ce/British_Museum_Marine_Chronometer.jpg/255px-British_Museum_Marine_Chronometer.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/c/ce/British_Museum_Marine_Chronometer.jpg/340px-British_Museum_Marine_Chronometer.jpg 2x" data-file-width="1512" data-file-height="2496" /></a><figcaption><a href="/wiki/Ship%27s_chronometer_from_HMS_Beagle" title="Ship's chronometer from HMS Beagle">Ship's chronometer from HMS Beagle</a> made by <a href="/wiki/Thomas_Earnshaw" title="Thomas Earnshaw">Thomas Earnshaw</a>. <a href="/wiki/British_Museum" title="British Museum">British Museum</a>, London.</figcaption></figure> When the <a href="/wiki/Napoleonic_Wars" title="Napoleonic Wars">Napoleonic Wars</a> ended in 1815, the <a href="/wiki/Pax_Britannica" title="Pax Britannica">Pax Britannica</a> saw seafaring nations competing in colonisation and rapid industrialisation.

The ship was to stop at specified points for a four-day rating of the chronometers and to check them by <a href="/wiki/Celestial_navigation" title="Celestial navigation">astronomical observations</a>: it was essential to take observations at <a href="/wiki/Praia" title="Praia">Porto Praya</a> and <a href="/wiki/Fernando_de_Noronha" title="Fernando de Noronha">Fernando de Noronha</a> to calibrate against the previous surveys of <a href="/wiki/William_Fitzwilliam_Owen" title="William Fitzwilliam Owen">William Fitzwilliam Owen</a> and <a href="/wiki/Henry_Foster_(scientist)" title="Henry Foster (scientist)">Henry Foster</a>.

He made an agreement with the owner of a small merchant-vessel to take himself and five others back to South America, but a kind uncle heard of this and contacted the Admiralty. Soon afterwards, FitzRoy heard that he was to be appointed commander of <a href="/wiki/HMS_Chanticleer_(1808)" title="HMS Chanticleer (1808)">HMS Chanticleer</a> to go to Tierra del Fuego, but due to her poor condition, Beagle was substituted. On 27 June 1831, FitzRoy was commissioned as commander of the voyage, and Lieutenants <a href="/wiki/John_Clements_Wickham" title="John Clements Wickham">John Clements Wickham</a> and <a href="/wiki/Bartholomew_Sulivan" title="Bartholomew Sulivan">Bartholomew James Sulivan</a> were both appointed.<a href="#cite_note-fitz13-14">[14]</a> Captain <a href="/wiki/Francis_Beaufort" title="Francis Beaufort">Francis Beaufort</a>, the Hydrographer of the Admiralty, was invited to decide on the use that could be made of the voyage to continue the survey, and he discussed with FitzRoy plans for a voyage of several years, including a continuation of the trip around the world to establish median distances. Beagle was <a href="/wiki/Ship_commissioning" title="Ship commissioning">commissioned</a> on 4 July 1831, under the command of Captain FitzRoy, who promptly spared no expense in having Beagle extensively refitted. Beagle was immediately taken into dock for extensive rebuilding and refitting. As she required a new deck, FitzRoy had the upper-deck raised considerably, by 8 inches (200 mm) aft and 12 inches (300 mm) forward.<a href="#cite_note-fitz17-15">[15]</a> The <a href="/wiki/Cherokee_class_brig-sloop" class="mw-redirect" title="Cherokee class brig-sloop">Cherokee-class brig-sloops</a> had the reputation of being "coffin brigs", which handled badly and were prone to sinking.<a href="#cite_note-PortCities-16">[16]</a> By helping the decks to drain more quickly with less water collecting in the <a href="/wiki/Gunwale" title="Gunwale">gunnels</a>, the raised deck gave Beagle better handling and made her less liable to become top-heavy and capsize. Additional sheathing to the hull added about seven tons to her <a href="/wiki/Builder%27s_Old_Measurement" title="Builder's Old Measurement">burthen</a> and perhaps fifteen to her displacement.<a href="#cite_note-fitz17-15">[15]</a> The ship was one of the first to test the <a href="/wiki/Lightning_rod" title="Lightning rod">lightning conductor</a> invented by <a href="/wiki/William_Snow_Harris" title="William Snow Harris">William Snow Harris</a>.

The officer class of the Army and Navy provided a way to ascend this hierarchy; the <a href="/wiki/Ship%27s_doctor" class="mw-redirect" title="Ship's doctor">ship's surgeon</a> often collected specimens on voyages, and <a href="/wiki/Robert_McCormick_(explorer)" title="Robert McCormick (explorer)">Robert McCormick</a> had secured the position on Beagle after taking part in earlier expeditions and studying natural history.

Far from wanting this,<a href="#cite_note-Letter_106-34">[34]</a><a href="#cite_note-letter:_199-55">[55]</a> Darwin's concern was to maintain control over his collection.

Darwin's notebooks show complete professionalism that he had probably learnt at the <a href="/wiki/University_of_Edinburgh" title="University of Edinburgh">University of Edinburgh</a> when making natural history notes while exploring the shores of the <a href="/wiki/Firth_of_Forth" title="Firth of Forth">Firth of Forth</a> with his brother Erasmus in 1826 and studying marine invertebrates with <a href="/wiki/Robert_Edmund_Grant" class="mw-redirect" title="Robert Edmund Grant">Robert Edmund Grant</a> for a few months in 1827.<a href="#cite_note-kix-61">[61]</a> Darwin had also collected <a href="/wiki/Beetle" title="Beetle">beetles</a> at Cambridge, but he was a novice in all other areas of natural history. During the voyage, Darwin investigated small invertebrates while collecting specimens of other creatures for experts to examine and describe once Beagle had returned to England.<a href="#cite_note-fieldnotesGalapagos-32">[32]</a> More than half of his carefully organised zoology notes deal with marine invertebrates. The notes also record closely reasoned interpretations of what he found about their complex internal anatomy while dissecting specimens under his microscope and small experiments on their response to stimulation. His onshore observations included intense, analytical comments on possible reasons for the behaviour, distribution, and relation to their environment of the creatures he saw. He made good use of the ship's excellent library of books on natural history but continually questioned their correctness.<a href="#cite_note-kx-62">[62]</a> Geology was Darwin's "principal pursuit" on the expedition, and his notes on that subject were almost four times larger than his zoology notes, although he kept extensive records on both. During the voyage, he wrote to his sister that "there is nothing like geology; the pleasure of the first days partridge shooting or first days hunting cannot be compared to finding a fine group of fossil bones, which tell their story of former times with almost a living tongue". To him, investigating geology brought reasoning into play and gave him opportunities for theorising.<a href="#cite_note-kix-61">[61]</a> <div class="mw-heading mw-heading2"><h2 id="Voyage">Voyage</h2>[<a href="/w/index.php?title=Second_voyage_of_HMS_Beagle&action=edit&section=7" title="Edit section: Voyage">edit</a>]</div> <figure class="mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Voyage_of_the_Beagle-en.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/e/ee/Voyage_of_the_Beagle-en.svg/500px-Voyage_of_the_Beagle-en.svg.png" decoding="async" width="500" height="250" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/e/ee/Voyage_of_the_Beagle-en.svg/750px-Voyage_of_the_Beagle-en.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/e/ee/Voyage_of_the_Beagle-en.svg/1000px-Voyage_of_the_Beagle-en.svg.png 2x" data-file-width="1024" data-file-height="512" /></a><figcaption>The voyage of Beagle</figcaption></figure> Charles Darwin had been told that Beagle was expected to sail about the end of September 1831,<a href="#cite_note-Letter_106-34">[34]</a> but fitting out took longer.

Repeated Westerly gales caused delays, and forced them to turn back after departing on 10 and 21 December. Drunkenness at Christmas lost another day. Finally, on the morning of 27 December, Beagle left its anchorage in the Barn Pool, under <a href="/wiki/Mount_Edgcumbe_Country_Park" title="Mount Edgcumbe Country Park">Mount Edgecumbe</a> on the west side of <a href="/wiki/Plymouth_Sound" title="Plymouth Sound">Plymouth Sound</a> and set out on its surveying expedition.<a href="#cite_note-63">[63]</a> <div class="mw-heading mw-heading3"><h3 id="Atlantic_islands">Atlantic islands</h3>[<a href="/w/index.php?title=Second_voyage_of_HMS_Beagle&action=edit&section=8" title="Edit section: Atlantic islands">edit</a>]</div> Beagle touched at <a href="/wiki/Madeira" title="Madeira">Madeira</a> for a confirmed position without stopping.

Although tantalisingly near to the town of <a href="/wiki/Santa_Cruz_de_Tenerife" title="Santa Cruz de Tenerife">Santa Cruz</a>, to Darwin's intense disappointment, they were denied landing. With improving weather conditions, they sailed on. On 10 January, Darwin tried out a <a href="/wiki/Plankton_net" title="Plankton net">plankton net</a> he had devised to be towed behind the ship—only the second recorded use of such a net (after use by <a href="/wiki/John_Vaughan_Thompson" title="John Vaughan Thompson">John Vaughan Thompson</a> in 1816). Next day, he noted the great number of animals collected far from land and wrote: "Many of these creatures so low in the scale of nature are most exquisite in their forms & rich colours. — It creates a feeling of wonder that so much beauty should be apparently created for such little purpose."<a href="#cite_note-64">[64]</a> Six days later, they made their first landing at <a href="/wiki/Praia" title="Praia">Praia</a> on the volcanic island of <a href="/wiki/Santiago,_Cape_Verde" title="Santiago, Cape Verde">Santiago</a> in the <a href="/wiki/Cape_Verde" title="Cape Verde">Cape Verde</a> Islands. It is here that Darwin's description in his published <a href="/wiki/The_Voyage_of_the_Beagle" title="The Voyage of the Beagle">Journal</a> begins.<a href="#cite_note-65">[65]</a> His initial impression was of a desolate and sterile volcanic island. However, upon visiting the town, he came to a deep valley where he "first saw the glory of tropical vegetation" and had "a glorious day", finding overwhelming novelty in the sights and sounds. FitzRoy set up tents and an observatory on <a href="/wiki/Santa_Maria_Island,_Cape_Verde" class="mw-redirect" title="Santa Maria Island, Cape Verde">Quail Island</a> to determine the exact position of the islands, while Darwin collected numerous sea animals, delighting in vivid tropical corals in tidal pools, and investigating the geology of Quail Island.<a href="#cite_note-66">[66]</a><a href="#cite_note-67">[67]</a> Though <a href="/wiki/Charles_Daubeny" title="Charles Daubeny">Daubeny</a>'s book in Beagle's library described the volcanic geology of the Canary Islands, it said that the structure of the Cape Verde Islands was "too imperfectly known". Darwin saw Quail Island as his key to understanding the structure of St. Jago and made careful studies of its <a href="/wiki/Stratigraphy" title="Stratigraphy">stratigraphy</a> in the way he had learnt from Adam Sedgwick. He collected specimens and described a white layer of hard white rock formed from crushed coral and seashells lying between layers of black volcanic rocks, and noted a similar white layer running horizontally in the black cliffs of St. Jago at 40 feet (12 m) above sea level. The seashells were, as far as he could tell, "the same as those of present day". He speculated that in geologically recent times a lava flow had covered this shell sand on the sea bed, and then the strata had slowly risen to their present level. Charles Lyell's Principles of Geology presented a thesis of gradual rising and falling of the Earth's crust illustrated by the changing levels of the <a href="/wiki/Macellum_of_Pozzuoli" title="Macellum of Pozzuoli">Temple of Serapis</a>. Darwin implicitly supported Lyell by remarking that "Dr. Daubeny when mentioning the present state of the temple of Serapis. doubts the possibility of a surface of country being raised without cracking buildings on it. – I feel sure at St Jago in some places a town might have been raised without injuring a house."<a href="#cite_note-68">[68]</a> Later, in his first letter to Henslow, he wrote that "The geology was preeminently interesting & I believe quite new: there are some facts on a large scale of upraised coast ... that would interest Mr. Lyell."<a href="#cite_note-Letter_171-69">[69]</a> While still on the island, Darwin was inspired to think of writing a book on geology,<a href="#cite_note-70">[70]</a> and later wrote of "seeing a thing never seen by Lyell, one yet saw it partially through his eyes".<a href="#cite_note-71">[71]</a> Beagle's surgeon <a href="/wiki/Robert_McCormick_(explorer)" title="Robert McCormick (explorer)">Robert McCormick</a> sought fame and fortune as an explorer.<a href="#cite_note-f196-72">[72]</a> When they first met at the start of the voyage, Darwin had commented that "My friend [McCormick] is an ass, but we jog on very amicably".<a href="#cite_note-Letter_144-57">[57]</a> They walked into the countryside of St. Jago together,<a href="#cite_note-73">[73]</a> and Darwin, influenced by Lyell, found the surgeon's approach old-fashioned.<a href="#cite_note-Letter_171a-74">[74]</a> They found a remarkable <a href="/wiki/Baobab" class="mw-redirect" title="Baobab">baobab</a> tree, which FitzRoy measured and sketched.

FitzRoy extended their stay to 23 days to complete his measurements of <a href="/wiki/Magnetic_anomaly" title="Magnetic anomaly">magnetism</a>.<a href="#cite_note-75">[75]</a> Darwin subsequently wrote to Henslow that his collecting included "several specimens of an Octopus, which possessed a most marvellous power of changing its colours; equalling any chamaelion, & evidently accommodating the changes to the colour of the ground which it passed over.—yellowish green, dark brown & red were the prevailing colours: this fact appears to be new, as far as I can find out."<a href="#cite_note-Letter_171-69">[69]</a> Henslow replied that "The fact is not new, but any fresh observations will be highly important."<a href="#cite_note-Letter_196-76">[76]</a> McCormick increasingly resented the favours FitzRoy gave to assist Darwin with collecting. On 16 February, FitzRoy landed a small party including himself and Darwin on <a href="/wiki/Saint_Peter_and_Paul_Rocks" class="mw-redirect" title="Saint Peter and Paul Rocks">St. Paul's Rocks</a>, finding the seabirds so tame that they could be killed easily, while an exasperated McCormick was left circling the islets in a second small boat.<a href="#cite_note-77">[77]</a> That evening, novices were greeted by a pseudo-<a href="/wiki/Neptune_(mythology)" title="Neptune (mythology)">Neptune</a>, and in the morning, they crossed the <a href="/wiki/Equator" title="Equator">equator</a> with the traditional <a href="/wiki/Line-crossing_ceremony" title="Line-crossing ceremony">line-crossing ceremony</a>.<a href="#cite_note-78">[78]</a> Darwin had a special position as a guest and social equal of the captain, so junior officers called him "sir" until the captain dubbed Darwin Philos for "ship's philosopher", which became his suitably respectful nickname.<a href="#cite_note-79">[79]</a> <div class="mw-heading mw-heading3"><h3 id="Surveying_South_America">Surveying South America</h3>[<a href="/w/index.php?title=Second_voyage_of_HMS_Beagle&action=edit&section=9" title="Edit section: Surveying South America">edit</a>]</div> In South America, Beagle carried out its survey work going to and fro along the coasts to allow careful measurement and rechecking.

Darwin had never seen "so complete & grievous a change". Jemmy came on board and dined using his cutlery properly, speaking English as well as ever, then assured them that he "had not the least wish to return to England" and was "happy and contented", leaving them gifts of otter skins and arrowheads before returning to the canoe to join his wife.<a href="#cite_note-FOOTNOTEKeynes2001[httpdarwin-onlineorgukcontentframesetviewtypetextitemIDF1925pageseq258_226–227].-146">[146]</a> Of the first visit, Darwin had written that "Viewing such men, one can hardly make oneself believe that they are fellow creatures placed in the same world. ....

The river cut through a series of rises, then through plateaux forming wide plains covered with shells and shingle.

Several of the smaller rheas were seen in the distance but were too elusive to catch.<a href="#cite_note-B63-271-130">[130]</a> The expedition approached the Andes but had to turn back. Darwin summarised his speculation in his essay on the Elevation of Patagonia. Though tentative, it challenged Lyell's ideas. Darwin drew on measurements by Beagle's officers, as well as his own measurements, to propose that the plains had been raised in successive stages by forces acting over a wide area, rather than smaller-scale actions in a continuous movement. However, he supported Lyell in finding evidence to dismiss a sudden deluge when normal processes were suddenly speeded. Seashells he had found far inland still showing their colour suggested to him that the process had been relatively recent and could have affected human history.<a href="#cite_note-herb16-152">[152]</a> <div class="mw-heading mw-heading4"><h4 id="West_coast_of_South_America">West coast of South America</h4>[<a href="/w/index.php?title=Second_voyage_of_HMS_Beagle&action=edit&section=14" title="Edit section: West coast of South America">edit</a>]</div> <figure class="mw-default-size mw-halign-right" typeof="mw:File/Thumb"><a href="/wiki/File:Cerro_La_Campana.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/2/28/Cerro_La_Campana.jpg/290px-Cerro_La_Campana.jpg" decoding="async" width="290" height="218" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/2/28/Cerro_La_Campana.jpg/435px-Cerro_La_Campana.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/2/28/Cerro_La_Campana.jpg/580px-Cerro_La_Campana.jpg 2x" data-file-width="2592" data-file-height="1944" /></a><figcaption><a href="/wiki/Cerro_La_Campana" title="Cerro La Campana">Cerro La Campana</a> ("The Bell Mountain"), which Darwin ascended on 17 August 1834</figcaption></figure> Beagle and Adventure now surveyed the Straits of Magellan before sailing north up the west coast, reaching <a href="/wiki/Chilo%C3%A9_Island" title="Chiloé Island">Chiloé Island</a> in the wet and heavily wooded <a href="/wiki/Chilo%C3%A9_Archipelago" title="Chiloé Archipelago">Chiloé Archipelago</a> on 28 June 1834.

Arriving at Tahiti on 15 November, he soon found interest in luxuriant vegetation and the pleasant intelligent natives who showed the benefits of Christianity, refuting allegations he had read about tyrannical missionaries overturning indigenous cultures.<a href="#cite_note-183">[182]</a> On 19 December, they reached New Zealand, where Darwin thought the tattooed <a href="/wiki/M%C4%81ori_people" title="Māori people">Māori</a> to be savages with the character of a much lower order than the Tahitians. He also noted that they and their homes were "filthily dirty and offensive". Darwin saw missionaries bringing improvement in character, as well as new farming practices with an exemplary "English farm" employing natives. Richard Matthews was left here with his elder brother Joseph Matthews who was a missionary at <a href="/wiki/Kaitaia" title="Kaitaia">Kaitaia</a>. Darwin and FitzRoy agreed that missionaries had been unfairly misrepresented in tracts, particularly one written by the artist <a href="/wiki/Augustus_Earle" title="Augustus Earle">Augustus Earle</a> which he had left on the ship.

The zoologist <a href="/wiki/Andrew_Smith_(zoologist)" title="Andrew Smith (zoologist)">Andrew Smith</a> showed him formations, and later discussed the large animals living on sparse vegetation, showing that a lack of luxuriant vegetation did not explain the extinction of the giant creatures in South America.<a href="#cite_note-Rascals-200">[199]</a> Around 15 June, Darwin and FitzRoy visited the noted astronomer Sir <a href="/wiki/John_Herschel" title="John Herschel">John Herschel</a>. In his diary, Darwin called this "the most memorable event which, for a long period, I have had the good fortune to enjoy." His zeal for science had been stirred at Cambridge by reading Herschel's book on philosophy of science, which had guided his theorising during the voyage.<a href="#cite_note-Rascals-200">[199]</a> Their discussion is not recorded, but a few months earlier, on 20 February 1836, Herschel had written to Lyell praising his Principles of Geology as a work which would bring "a complete revolution in [its] subject, by altering entirely the point of view in which it must thenceforward be contemplated." and opening a way for bold speculation on "that mystery of mysteries, the replacement of extinct species by others." Herschel himself thought <a href="/wiki/Catastrophism" title="Catastrophism">catastrophic extinction and renewal</a> "an inadequate conception of the Creator", and by analogy with other <a href="/wiki/Physical_law" class="mw-redirect" title="Physical law">intermediate causes</a> "the origination of fresh species, could it ever come under our cognizance, would be found to be a natural in contradistinction to a miraculous process".<a href="#cite_note-hersch-201">[200]</a> In Cape Town, missionaries were being accused of causing racial tension and profiteering, and after Beagle set to sea on 18 June, FitzRoy wrote an open letter to the <a href="/wiki/Evangelicalism" title="Evangelicalism">evangelical</a> South African Christian Recorder on the Moral State of Tahiti incorporating extracts from both his and Darwin's diaries to defend the reputation of missionaries. This was given to a passing ship that took it to Cape Town to become FitzRoy's (and Darwin's) first published work.<a href="#cite_note-202">[201]</a> On 8 July, they stopped at <a href="/wiki/St._Helena" class="mw-redirect" title="St. Helena">St. Helena</a> for six days.

He examined beds high on the hill that had been taken as seashells showing that St. Helena had risen from the ocean in recent times, but Darwin identified them as extinct species of land-shells. He noted that woodland had been destroyed by goats and hogs that had run wild since being introduced in 1502,<a href="#cite_note-204">[203]</a> and native vegetation only predominated on high steep ridges, having been replaced by imported species.<a href="#cite_note-205">[204]</a> At this stage, Darwin had an acute interest in the island <a href="/wiki/Biogeography" title="Biogeography">biogeography</a>, and his description of St Helena as "a little centre of creation" in his geological diary reflects Charles Lyell's speculation in volume 2 of Principles of Geology that the island would have acted as a "focus of creative force".<a href="#cite_note-Rascals-200">[199]</a> He later recalled believing in the permanence of species, but "as far as I can remember, vague doubts occasionally flitted across my mind".<a href="#cite_note-Poulton-206">[205]</a> When organising his Ornithological Notes between mid June and August,<a href="#cite_note-207">[206]</a> Darwin expanded on his initial notes on the Galapagos <a href="/wiki/Mockingbird" title="Mockingbird">mockingbird</a> Mimus thenca:<a href="#cite_note-fieldnotesGalapagos-32">[32]</a> <blockquote> These birds are closely allied in appearance to the Thenca of Chile or Callandra of la Plata. ...

As a scientific celebrity with a reputation established by his fossils and the wide distribution of <a href="/wiki/Extracts_from_Letters_to_Henslow" title="Extracts from Letters to Henslow">Extracts from Letters to Henslow</a> on South American natural history and geology, Darwin toured <a href="/wiki/London" title="London">London</a>'s social institutions. By this time, he was part of the "scientific <a href="/wiki/The_Establishment" title="The Establishment">establishment</a>", collaborating with expert naturalists to describe his specimens and working on ideas he had been developing during the voyage. Charles Lyell gave him enthusiastic backing. In December 1836, Darwin presented a talk to the <a href="/wiki/Cambridge_Philosophical_Society" title="Cambridge Philosophical Society">Cambridge Philosophical Society</a>.

On 30 December, the question was settled by FitzRoy taking the advice of <a href="/wiki/William_Broderip" title="William Broderip">William Broderip</a> that Darwin's journal should form the third volume of the Narrative. Darwin set to work reorganising his diary, trimming it, and incorporating scientific material from his notes. He completed his <a href="/wiki/The_Voyage_of_the_Beagle" title="The Voyage of the Beagle">Journal and Remarks</a> (now commonly known as The Voyage of the Beagle) in August 1837, but FitzRoy was slower, and the three volumes were published in August 1839.<a href="#cite_note-K01intro-225">[224]</a> <a href="/wiki/Syms_Covington" title="Syms Covington">Syms Covington</a> stayed with Darwin as his servant.
