Geological Observations on South America

Geological Observations on South America

Of the remarkable trilogy constituted by Darwins writings which deal with the geology of the Beagle, the member which has perhaps attracted least attention, up to the present time is that which treats of the geology of South America. The actual writing of this book appears to have occupied Darwin a shorter period than either of the other volumes of the series; his diary records that the work was accomplished within ten months, namely, between July 1844 and April 1845; but the book was not actually issued till late in the year following, the preface bearing the date September 1846. Altogether, as Darwin informs us in his Autobiography, the geological books consumed four and a half years steady work, most of the remainder of the ten years that elapsed between the return of the Beagle, and the completion of his geological books being, it is sad to relate, lost through illness! Concerning the Geological Observations on South America, Darwin wrote to his friend Lyell, as follows:My volume will be about 240 pages, dreadfully dull, yet much condensed. I think whenever you have time to look through it, you will think the collection of facts on the elevation of the land and on the formation of terraces pretty good. Much condensed is the verdict that everyone must endorse, on rising from the perusal of this remarkable book; but by no means dull. The three and a half years from April 1832 to September 1835, were spent by Darwin in South America, and were devoted to continuous scientific work; the problems he dealt with were either purely geological or those which constitute the borderland between the geological and biological sciences. It is impossible to read the journal which he kept during this time without being impressed by the conviction that it contains all the germs of thought which afterwards developed into the Origin of Species. But it is equally evident that after his return to England, biological speculations gradually began to exercise a more exclusive sway over Darwins mind, and tended to dispossess geology, which during the actual period of the voyage certainly engrossed most of his time and attention. The wonderful series of observations made during those three and a half years in South America could scarcely be done justice to, in the 240 pages devoted to their exposition. That he executed the work of preparing the book on South America in somewhat the manner of a task, is shown by many references in his letters. Writing to Sir Joseph Hooker in 1845, he says, I hope this next summer to finish my South American Geology, then to get out a little Zoology, and HURRAH FOR MY SPECIES WORK! ......Buy Now (To Read More)
