Alberto, isn't the full patent in the footnote of my book?? When I get home I can screen shot the page for you out of my gum printing book but don't you have it? Pouncy's process in there too.

There are two citations, the first to Towler 275-76 (that is: The Silver Sunbeam, 1864, which I have easily found with Internet Archive, and the second to Nadeau 2,7-9.
