Charles Darwin

This volume is part of the definitive edition of letters written by and to Charles Darwin, the most celebrated naturalist of the nineteenth century. Notes and appendixes put these fascinating and wide-ranging letters in context, making the letters accessible to both scholars and general readers. Darwin depended on correspondence to collect data from all over the world and to discuss his emerging ideas with scientific colleagues, many of whom he never met in person. The letters are published chronologically: volume 22 includes letters from 1874, the year in which Darwin completed his research on insectivorous plants and published second editions of Descent of Man and Coral Reefs. The year also saw an acrimonious dispute between Darwin and St George Jackson Mivart as a result of an anonymous review the latter had written in which he criticised Darwin's son George.

Geological Observations on the Volcanic Islands, visited during the Voyage of H. M. S. Beagle is a book written by the English naturalist Charles Darwin. The book was published in 1844, and is based on his travels during the second voyage of HMS Beagle, commanded by captain Robert FitzRoy. It is the second book in a series of geology books written by Darwin, and also includes The Structure and Distribution of Coral Reefs, published in 1842, and Geological Observations on South America, published in 1846 The text contains seven chapters, and includes observations made during Darwin's travels to the volcanic island of St. Jago in Cape Verde, the Fernando de Noronha archipelago, Ascension Island, the island of Saint Helena, the Gal pagos Islands, James Island, New Zealand, Australia, Van Diemen's Land, and the Cape of Good Hope. The book includes one of the earliest accounts of the process of magmatic differentiation. While observing a basaltic lava flow in the Gal pagos Islands, Darwin observed that "crystals sink from their weight" 3] note 1] and that this "throws light on the separation of the high silica versus low silica series of rocks." 2] This was the first proposal of the fractional crystallization hypothesis of magma differentiation that was further developed and demonstrated in the 20th century. The geologist Archibald Geikie praised the book, calling it "the best authority on the general geological structure of most of the regions it describes," and that Darwin was "one of the earliest writers to recognize the magnitude of denudation to which even recent geological accumulations have been subjected." A second edition of the book, published in 1876, combines Geological Observations on the Volcanic Islands with Geological Observations on South America.
