Principles of geology : being an attempt to explain the former changes of the earth's surface, by reference to causes now in operation
Principles of Geology is a scientific treatise by Charles Lyell, published in London by John Murray in 1830, written for geologists and general readers interested in the earth's history. The pictures are a plain title page in spaced capitals with centred lines of small serif type and a publisher's imprint at the foot, with no imagery beyond typography; a designer might take from it the restrained hierarchy of letterspaced caps, centred classical layout, and generous margins typical of early nineteenth-century printing.
