While we're at it, perhaps you'd like to comment, in as many words as
you like, on how similar gelatin and gum are and why I should take the
hardening of gelatin with chrome alum as a model for the photoprocess of
dichromated gum. ;-) I don't think gum and gelatin are are much closer
than gum and leather, and they are sure way farther apart than gelatin
and leather.
