Have you tried the email address in the Gutenberg file?
These are missing that particular volume:
http://catalog.hathitrust.org/Record/011261032
http://catalog.hathitrust.org/Record/011261033
This is not available:
http://catalog.hathitrust.org/Record/100327200
This one at least looks like the same text:
http://babel.hathitrust.org/cgi/pt?i...39015014614948
This has probably the same content too:
http://babel.hathitrust.org/cgi/pt?i...33433107655205
Probably nothing you didn't know already.
