WILSON Department of History of Medicine, Medical School, Universi~' of Minnesota, Box 506 Mayo, 420 Delaware Street SE, Minneapolis, MN 55455, USA Abstract: Born in Scotland at the end of the eighteenth century, Charles Lyell spent his early life in Hampshire in the midst of the kind of comfortable rural society described in Jane Austen's novels. Influenced by his father, who was a keen botanist, the young Lyell collected butterflies and studied natural hisory. As a student at Oxford, he attended the Revd William Buckland's lectures on geology and continued to pursue geology while studying for the bar at Lincoln's Inn. In 1824 Lyell wrote his first scientific paper on the freshwater limestones and marls of Scottish lakes, demonstrating their detailed similarity to ancient freshwater formations among the Tertiary strata of the Paris Basin. Throughout his life Lyell remained an active field geologist, travelling throughout Europe from Sicily to Scandinavia. He made repeated geological tours through the Swiss and Austrian Alps and studied intensely the Tertiary strata of France, Belgium and England. He examined the geology of North America from Nova Scotia to the Mississippi Delta, working in the field in all weather. In 1853-1854 he spent several months studying the volcanic geology of Madeira and the Canary Islands and in 1857 and 1858 revisited Sicily to spend arduous weeks studying Mount Etna. In his seventy-fifth year and nearly blind, he travelled to the south of France to examine the caves of Aurignac and the Dordogne. In 1830 in the Principles of Geology Lyell challenged the assumption of a cooling Earth and of the greater former intensity of volcanic action and other geological forces. He separated geology from cosmology, pointing out that the crust of the Earth told nothing of its origin. What geology did reveal was an unending cycle of changes such as were still going on. In his metamorphic theory developed in the Elements of Geology, Lyell showed how the various classes of igneous and metamorphic rocks were formed in the gradual elevation of mountains. Lyell's theories brought about a revolution in geology, changing the meaning of geological data. In successive editions of the Principles and the Elements, two books of American travel, and the Antiquity of Man, Lyell's stature as an author and as a scientist grew steadily throughout his lifetime, the sale of his books often exceeding the publisher's expectations. Liberal in his sympathies, Lyell worked effectively for the reform of English university education and during the American Civil War defended the Union against its British critics Charles Lyell was born at Kinnordy House in the kind of quiet comfortable society described by Forfarshire, Scotland on 14 November 1797, the Jane Austen- comfortable but anxious, menaced son of Charles Lyell, laird of Kinnordy.

WILSON accumulated in the recent past from the interactions of the river with the sea and the wind. In September Lyell visited the island of Staffa to see its famous basalt columns and Fingal's Cave. At Oxford in the spring of 1818 Lyell attended his second course of Buckland's lectures on mineralogy and geology. During the summer he accompanied his family on a tour on the Continent. At Paris, Lyell visited the Jardin des Plantes to see the bones of fossil animals described by Cuvier and to read Cuvier's books on fossil remains (Cuvier 1812) and on the geology of the Paris Basin (Cuvier & Brongniart 1811). At Chamonix in Switzerland he saw how the glacier of Bosson had recently advanced, treading down pine forests in front of it. While the Lyell family travelled along the roads in Switzerland, Lyell made parallel excursions in the Alps, often walking 35-40 miles a day. In the autumn he returned to Oxford for his final year and graduated there in the spring of 1819. In March 1819 Lyell was also elected a Member of the Geological Society of London. In 1820 Lyell began to study law at Lincoln's Inn, but his eyes, which had begun to trouble him the year before while he was studying for examin- Fig. 1. Sir Charles Lyell in 1853.
