Another parameter of water quality is hardness.
I read it alongside the original, and alongside three other English translations (by Eleanor Marx Aveling, Francis Steegmuller, and Geoffrey Wall) and I consistently admired Davis's attempts to get as close as possible to a quality of hardness, or coldness, in Flaubert's own prose.
