In the process of doing some research yesterday I came across some old books that are available for free download via Google Books. I know not everyone shares my particular affinity for yellowing 19th century science books, but if you do you might want to check out some of these titles;
Georges Cuvier - Essay on the Theory of the Earth (English translation)
William Buckland - Geology and Mineralogy Considered with Reference to Natural Theology
William Buckland - Reliquiae Diluvianae
W.J. Broderip - Zoological Recreations
Robert Chambers - Vestiges of the Natural History of Creation, With a Sequel
Charles Lyell - The Geological Evidences of the Antiquity of Man
Thomas Browne - Pseudodoxia Epidemica
Edward Hitchcock - The Religion of Geology and Its Connected Sciences
T.H. Huxley - American Addresses
Richard Owen - Palaeontology
John Phillips - Life on Earth
Ernest Ingersoll - The Life of Animals: The Mammals
T.H. Huxley - Discourses: Biological and Geological
John Pratt - Scripture and Science Not at Variance
There's one or two others that I obtained yesterday, but their names escape me at the moment. I don't particularly like reading books on the computer (my eyes feel like they're going to fall out of my head after a few minutes), but it's hard to beat free pdfs of books that I probably would never find (or have to shell out hundreds of dollars for) otherwise.
Good finds! To add to the list of free google books offerings, I recently found a lengthy memoir on the Thalattosauria (short-lived group of LTr marine reptiles) from 1905. It's got some great reconstructions of skull material.

The Life on Earth link is broken (you duped the previous one)
Good find, Brian, but cthulhu's minion is right.
Here's the proper links:
John Phillips - Life on Earth
T.H. Huxley - Discourses: Biological and Geological
The Buckland 'Geology and Mineralogy' link is to vol 2 only. Vol 1 is at Geology and Mineralogy Considered with Reference to Natural Theology Vol 1
