Note 27 — PETER KALM’s TRAVELS. (continued 5)
Johann Reinhold Forster translation
As the shells of oysters are a marine animal production, and their cavities are full of particles of sea-water, the moisture of it flies off, leaving behind its salt; when the shells are burnt, and the lime is slacked, the salt mixes with the lime: and though the mortar of such a lime grows ever so dry, the particles of salt immediately attract the moisture of the air, and cause that dampness complained of here.
