Mark Twain owned a copy of White's _A History of the Warfare of Science
with Theology in Christendom._.  A two-volume set published in 1901.  The
volumes are filled with his marginalia. Among such comments are "Doubtless
theology & dysentery are two of the most enervating diseases a person can
have"  and also referred to the works as "most amusing." These volumes are
in the Mark Twain Papers at Berkeley. The books are considered to be the
main inspiration for the final chapters of "The Secret History of
Eddypus."  Alan Gribben's _Mark Twain's Library: A Reconstruction_ reprints
the text of Twain's marginalia.
