Note 585 — Chapter XV · NAHUA ARTS AND MANUFACTURES.

'Whether a man desire the rude mettall, or to haue it molten, or beaten out, and cunningly made into any kinde of Iewell, hee shall find them ready wrought.' Peter Martyr, dec. v., lib. iv. Gomara and Gama state that they mixed gold and silver, as well as tin, with copper, for the manufacture of gimlets, axes, and chisels. Conq. Mex., fol. 318; Dos Piedras, pt ii., p. 26. Clavigero states that in Zacatollan two kinds of copper were found, hard and soft, so that there was no need of any hardening process. Storia Ant. del Messico, tom. iv., pp. 210-11.
