But the Lord's word endures forever." This is the word of good news which was preached to you.
Gold is defined by chemists to be the most perfect, the most ductile, the most tenacious, and the most unchangeable of all metals. Its specific gravity is about 19.3. A cubic foot of pure gold, cast and not hammered, weighs 1348lbs. In its native state, without mixture, it is yellow, and has no perceptible smell nor taste. When exposed to the action of the fire it becomes red hot before it melts, but in melting suffers no alteration; but if a strong heat be applied while in fusion, it becomes of a beautiful green colour. The continual action of any furnace, howsoever long applied, has no effect on any of its properties. It has been kept in a state of fusion for several months, in the furnace of a glass house, without suffering the smallest change. The electric and galvanic fluids inflame and convert it into a purple oxide, which is volatilized in the form of smoke. In the focus of a very powerful burning glass it becomes volatilized, and partially vitrified; so that we may say with the apostle, that, though gold is tried by the fire-abides the action of all culinary fires, howsoever applied, yet it perisheth by the celestial fire and the solar influence; the rays of the sun collected in the focus of a powerful burning glass, and the application of the electric fluid, destroy its colour, and alter and impair all its properties. This is but a late discovery; and previously to it a philosopher would have ridiculed St. Peter for saying, gold that perisheth.
