Lyell, Sir Charles, Bart., F.R.S. (1797-1875): was born at Kinnordy, the family home in central Forfarshire. At the age of seventeen he entered at Exeter College, Oxford, and afterwards obtained a second class in the final Honours School in Classics. As an undergraduate Lyell attended Prof. Buckland's lectures on Geology. On leaving Oxford Lyell was entered at Lincoln's Inn; a weakness of the eyes soon compelled him to give up reading, and he travelled abroad, finding many opportunities for field work. He was called to the Bar in 1825, and in the same year published some papers on geological subjects. From 1823-26 Lyell filled the post of Secretary to the Geological Society, and in 1826 was elected into the Royal Society. In 1830 the first volume of the "Principles of Geology" was published; the second volume appeared two years later. Speaking of this greatest of Lyell's services to Geology, Huxley writes: "I have recently read afresh the first edition of the "Principles of Geology," and when I consider that this remarkable book had been nearly thirty years in everybody's hands [in 1859], and that it brings home to any reader of ordinary intelligence a great principle and a great fact-- the principle that the past must be explained by the present, unless good cause be shown to the contrary; and the fact that, so far as our knowledge of the past history of life on our globe goes, no such cause can be shown--I cannot but believe that Lyell, for others, as for myself, was the chief agent in smoothing the road for Darwin" (Huxley's "Life and Letters," Volume II., page 190).
