continuation of heat and the admixture of other matters of unspecified composition.98 Darwin could not find this scheme attractive because, by his reckoning, trachyte was itself a segregation product formed during crystallization (see above). Nor does it appear to balance chemically, because there is no obvious way in which the silica-poor rocks such as basalt can be derived from trachyte. During the Beagle voyage, Darwin saw several primary districts where the geological underpinning of granite and

DARWIN'S INTEREST IN IGNEOUS GEOLOGY Darwin had been fascinated by chemistry since his early childhood.,51 As he recalled in his autobiography, he had been nicknamed Gas as a boy because of his chemistry experiments and he collected minerals. A greater rigor was imparted in his education at Edinburgh and Cambridge which well qualified him for examining the geology of the Beagle voyage.52 It is clear from Darwin's

thinking on the subject. OBSERVATIONS IN THE GALAPAGOS AND THE THEORY OF GRAVITY SETTLING Having made literally hundreds of pages of observations relating to the igneous rocks of South America, Darwin may have had these problems in mind when the Beagle departed the mainland on 7th September 1835 bound for the Gal pagos Archipelago. Here he enjoyed yet another splendid opportunity to study well-exposed volcanic rocks. It so happens that many of the rocks Darwin collected from the Gal pagos have

Scrope41-42 and Lyell43 were strongly opposed to the idea of elevation-craters44 which soon became linked to lie de Beaumont's (1798-1874) theories of catastrophic mountain formation. 45 After the Beagle voyage, Darwin was better disposed toward the theory and

explanation for the phenomenon. In March 1835, the Beagle was traversing the coast of Chile. At Concepcion, Darwin described a great many dykes of different compositions from the same area. He wrote: It may be doubted perhaps whether all the above dykes are of the same age, or whether it is possible that two dykes, so similarly circumstanced [i.e., in orientation and thickness], the one composed of Dolerite and the other a white Feldpathic stone, could have flowed from the same fluid mass. 78 He even

time in the formulation of the two theories should be explained. By the time the Beagle had departed the Gal pagos in October 1835, Darwin had made observations and collections that ultimately proved crucial to both his igneous and evolutionary theories. Although doubts about the fixity of species occurred to him during the voyage, it is well-known that he was to work on evolution only after his return to England. Similarly, Darwin's geology notes show very clearly that he had in mind some kind

He apparently worked on volcanic geology initially between October 1837 and June 1838.111 It was in this period that he read Von Buch's Isles Canaries, and may have first encountered Pattinson's process for the purification of lead both obvious influences on his igneous theory. At this time he also made several relevant entries in his A notebook and reworked the Beagle geology notes. In a jocular letter to a friend dated May 1838

continued neglecting the first production of trachyte, look at sulphur, salt, lime how comes it they do not flow out together? How are they eliminated? 90 Although he seems to have put his volcanic work aside immediately after the return, a further spur to his theorizing was his reading of Leopold Von Buch's Description Physique des Isles Canaries (which was newly translated into French and had not been present in the Beagle library). In this work, Von Buch describes an obsidian flow at Tenerife

Beagle, Darwin had seen the glaciers of Tierra del Fuego, which he valued as spectacles, or as the parent to icebergs, rather than as major geological forces. Using Darwin's unpublished geological manuscripts from the voyage of H.M.S.

Then a thundering crash shook us as the whole front of the ice cliff came crashing down (FitzRoy 1839, vol. 2: 216- 217). The wave the ice caused threatened to carry away the surveying boats. Darwin aided in their rescue. Disaster was averted. Glaciers had become more than spectacle; they had become experience.3 Darwin was witness to the creation of icebergs.

this was a thin assertion. From his Beagle period notes, it is clear that Darwin believed these were not settled questions. Stage 2:1837. Darwin's Manuscript of the Journal of Researches In 1837, three years after Darwin left Tierra del Fuego for the last time, he spent seven months transforming his Diary from the Beagle voyage into a book (FitzRoy 1839, vol. 3; Darwin 1839a). The three years from 1834 and 1837 had been full of developments, for Darwin, and for the field of geology as it related

some of the fossils he collected. The fossils allowed a statement on the age of the rocks to be offered, a statement which, although wrong on present information if only just was the best answer available at the time he wrote (i.e. Carboniferous; they are now known to be early Permian, but the Permian System had not been proposed at the time of the Beagle voyage).

before the 7th. It is at least possible that Captain FitzRoy, as commander of an expedition with the prime function of measuring latitude and longitude, called upon or made contact with Frankland as Surveyor-General soon after the Beagle reached Sullivans Cove and may well have introduced Darwin to him. With Frankland, Darwin would have found a community of interests. Frankland was born in Somerset, UK, in 1800, joined the army in 1819 and served in India (Eldershaw 1966: 410-411). He was

carried a translation of Agassiz's famous Neucha-tel address of July 1837. It is not known exactly when Darwin first read the address, either in the Edinburgh journal, or referred to elsewhere, possibly in the French scientific literature, but by the 27th of October 1838 he had written a passionate attack on Agassiz's work, and that of Venetz and Charpentier.

but, as a Uniformitarian , he did not accept the views of the catastrophists but thought that present geological processes had operated in the past at about the same intensity as they do now.

Sea A recurrent theme in Darwin's writings on the voyage of the Beagle is the relative movement of the land and the sea, commonly the uplift of the land so clearly seen by Darwin in South America. Oldroyd (1996: 177) noted that Darwin had associated uplift in South America with volcanic activity. In his writing on this subject as he saw it in the Hobart area, Darwin noted evidence of both uplift and subsidence of the land. He tended to think in terms of upward or downward movement of the

Muchos autores han afirmado que nada fue m s medular en la construcci n del pensamiento de Darwin que el gradualismo lyelliano e inclusive, que su fe en el gradualismo fue mayor que su confianza en la selecci n natural. Otro personaje merece ser mencionado por su contribuci n a la geolog a de la poca y su influencia directa sobre Darwin. Adam Sedgwick (1785-1873), quien durante un tiempo

However the evidence for this is not strong; although here and there in the notes from the Beagle period there are vague hints that the idea of mutability of species went though his mind, all the evidence suggests that it was not until after his return to England, in about March 1837, that his conversion to the evolutionary outlook occurred (Sulloway, 1982

Copies of all four volumes (albeit of different editions) of Kirby's book were aboard the Beagle (Burkhardt and Smith, 1985). Darwin used and annotated them frequently, referring to them in several places in his notes. It cannot be imagined that Charles Darwin would have taken the volumes of Introduction to Entomology with him into the
