Here’s the frontispiece from Charles Lyell’s Principles of Geology. The book was first published in three volumes in 1830 to 1833, but this is from an 1857 edition.

This cross-section shows an amazing understanding of the basic geologic processes that form the Earth’s crust: plutonism, volcanism, metamorphism, sedimentation, and folding.

Like most geologists (at least I assume), I’ve never read Principles of Geology. It is available online in many places, including several editions at Google Books.

From Lyell’s obituary in the New York Times, (date February 25, 1875):

But, though an evolutionist, Lyell was not a skeptic. He lived and died a Christian believer.
