formed, which the rest, by continual hissing, blow on till it passes
quite through the body, and then it immediately hardens, and resembles a
glass-ring, which whoever finds (as some old women and children are

generated, are called _Gleineu Nadroeth_; in English, Snake-stones. They
are small glass amulets, commonly about half as wide as our
finger-rings, but much thicker, of a green colour usually, though
sometimes blue, and waved with red and white."
