Henry,
I read 1200 volumes and said "what?". I looked up this publication in two volumes and found that it has 1200 pages. At 1200 volumes that Gustavus Vasa Fox was one prolific reader and writer.
I found the first volume of this set online at http://www.openlibrary.org/details/confidentialfox00vasarich , if some of this group would like to take a look. I'll be doing a little reading myself. Didn't find anything yet regard the Dunbar, but still looks interesting.
