Er........ Since when has 'ur' been an English prefix ? Archetypal or primitive
fine but the only 'ur' prefix in English refers to urine.
Has anybody out there tried to emulate Herschel's experiments with the use of
uric acid in photography ? I believe he used the natural product from the dog.
Was he using the acid as a developer or what ?
