Note 848 — BOOK XXXIII. THE NATURAL HISTORY OF METALS.647
John Bostock translation
For ductility and malleability, both which terms may perhaps be included in the “facilitas” of Pliny, gold is unrivalled among the metals. As to weight, it is heavier than lead, the specific gravity of gold being 19.258, and that of lead 11.352. Pliny is therefore wrong in both of these assertions.
