Preserved the unusual, and inconsistent, references to the Plates.
Sometimes Arabic numerals are used, but usually Roman numerals. Most
have "A" attached to the name (which was changed to "a" to avoid
confusion in the Roman numerals), but not VIII, and sometimes not in the
references to them.
Equations were converted to linear text, adding spacing and parentheses
as necessary. Greek characters were also replaced by Latin letters in
the Latin-1 version.
Replaced the oe ligature with the two characters in "Goethe" in the
front material.
Changed "fumarolles" to "fumaroles" on page 3: "fumaroles and
salfatares."
Changed "Lyall" to "Lyell" in footnote originally on page 9: "Daubeny,
Lyell, Phillips and others."
