I haven't been able to get the download to work, but 1865 is too old for dry plates - silver gelatin emulsion dry plates were invented in 1872. So I'm guessing this about "dry" collodion plates?
Thanks sincerely for the post/link. I've been reading "Nonsilver Printing Processes: Four selections, 1886-1927" edited by P.C. Bunnell and I recommend it to all who might have an interest in the history of alternative processes.
I posted this because I thought it was an interesting relic. It is verbose. But, I find the prose in the introduction to be an interesting statement of photography at the time.
I wonder if the Canon-Nikon debate would have led to a shootout back in 1865.
