Publisher's Synopsis
""Geological Observations on Volcanic Islands"" is a scientific book written by Charles Darwin, the famous naturalist, and author of ""On the Origin of Species."" In this book, Darwin describes his observations and findings during his journey to volcanic islands, including the Galapagos Islands, during his voyage on the HMS Beagle.The book is divided into three parts. The first part describes the geological formations and volcanic activity on the islands, including the types of rocks and minerals found, the formation of craters, and the eruption history of the volcanoes. The second part focuses on the flora and fauna of the islands, including the unique adaptations of the animals and plants to their volcanic environment. The third and final part discusses the implications of Darwin's observations for the study of geology and natural history.Throughout the book, Darwin uses his keen observational skills and scientific knowledge to provide detailed descriptions of the geological and biological features of the volcanic islands. He also draws on his understanding of evolution and natural selection to explain the adaptations of the island's plants and animals.""Geological Observations on Volcanic Islands"" is a seminal work in the field of geology and natural history and remains an important reference for scientists and researchers today. It is also a fascinating read for anyone interested in the natural world and the history of scientific discovery.The overlying basaltic lava is in some parts extremely vesicular, in others little so; it is of a black colour, but sometimes contains crystals of glassy feldspar, and seldom much olivine. These streams appear to have possessed singularly little fluidity; their side walls and lower ends being very steep, and even as much as between twenty and thirty feet in height. Their surface is extraordinarily rugged, and from a short distance appears as if studded with small craters.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
