Sorry about that Andro, just been reading a lot about collection of Nitrogen compounds from the air as "the water that does not wet the hand." Merelle makes the connection directly between collection of the Salt and the Mutus Libre imagery in his book "Mysteries of Alchemy," and the focus on this salt is the subject of much of the vinegar solvent to act on metals, from what I've read on the matter. Seemed like a popular theme to me, "everyone" was a poor wording choice.
