Note 407 — ACT I.
Reading edition
Talc.—Reed quotes from Giles Fletcher’s Russe Commonwealth, 1591, p. 10:—“In the province of Corelia, and about the river Duyna towards the North-sea, there groweth a soft rock which they call Slude. This they cut into pieces, and so tear it into thin flakes, which naturally it is apt for, and so use it for glasse lanthorns and such like. It giveth both inwards and outwards a clearer light then glasse, and for this respect is better than either glasse or horne; for that it neither breaketh like glasse, nor yet will burne like the lanthorne.”
