First Edition. Scrope’s work is considered “the earliest systematic treatise on volcanology, since it was the first attempt to frame a satisfactory theory of volcanic action and to show the part volcanoes have played in the Earth’s history” (Encyclopaedia Britannica). Scrope was among the first to address the role of pressure in volcanic systems: “In his work Considerations on Volcanos, Scrope had realized the effect of pressure on the solubility of water in magmas, and was one of the first to point out that decrease of pressure on a water-rich magma could explain volcanic explosions due to the release of dissolved water” (Sigurdsson et al., Encyclopedia of Volcanoes, p. 29). Scrope’s uniformitarian views on geology, expressed in Considerations and his later works, had a great influence on his friend Charles Lyell; Scrope in turn was influential in promoting Lyell’s new geology, helping Lyell complete the first volume of his Principles of Geology (1830) and reviewing the work favorably in the Quarterly Review.Book Id: 46066
