No, this is the reference to the dark reaction quote referred to later
in your post, which I referred to in another place in my post:

this does not say anything about dampness and low contrast, or dampness
and staining, as you referred to in your earlier post. But thanks for
the reference from the website. Perhaps I'm too particular about
citations, but if he doesn't say it in his book, I'd prefer that it not
be cited to his book.

You must have a different Blacklow than I do, because page 127 in mine
is simply a supply list. But this quote above, is about the dark
reaction; and does not say anything like what you said in your earlier

Well, since the page citations given here back up other attributions,
not the attributions you gave earlier to these authors, I have to say
I'm not terribly satisfied with the checking.
