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)
