Found it: it's on page 53 of Photo Aquatint, the second edition, in the
Postscript, the part that is in italics: "Certain difficulties will
sometimes occur, of which the causes are not always apparent. For instance,
using perhaps precisely the same procedure as we may have done before with
success, a print will develop itself clear and brilliant, but, shortly
before becoming dry, the film will melt and run and presently leave nothing
more than a smudgy mass."
