But the Lord's word endures forever." This is the word of good news which was preached to you.
Gold was considered the heaviest of all metals till the year 1748, when the knowledge of platina was brought to Europe by Don Antonio Ulloa: this, if it be a real metal, is the hardest and weightiest of all others. The specific gravity of gold is, as we have seen, 19.3 that of platina is from 20.6 to 23: but gold will ever be the most valuable of all metals, not merely from its scarcity, but from its beautiful colour and great ductility, by which it is applicable to so many uses, and its power of preserving its hue and polish without suffering the least tarnish or oxidation from the action of the air.
