[5] It may be mentioned in passing, that while Zinc is fusible at 3 degrees of Wedgwood's pyrometer, Silver at 22 degrees, Copper at 27 degrees, and Gold at 32 degrees, Cast Iron is only fusible at 130 degrees. Tin (one of the constituents of the ancient bronze) and Lead are fusible at much lower degrees than zinc. [6] The Romans named the other metals after the gods. Thus Quicksilver was called Mercury, Lead Saturn, Tin Jupiter, Copper Venus, Silver Luna, and so on; and our own language has received a colouring from the Roman nomenclature, which it continues to retain.

[10] Dr. Livingstone brought with him to England a piece of the Zambesi iron, which he sent to a skilled Birmingham blacksmith to test. The result was, that he pronounced the metal as strongly resembling Swedish or Russian; both of which kinds are smelted with charcoal. The African iron was found "highly carbonized," and "when chilled it possessed the properties of steel." [11] HOLINSHED, i. 517. Iron was also the currency of the Spartans, but it has been used as such in much more recent times. Adam Smith, in his Wealth of Nations (Book I. ch. 4, published in 1776), says, "there is at this day a village in Scotland where it is not uncommon, I am told, for a workman to carry nails, instead of money, to the baker's shop or the alehouse."

[13] See Dr. Pearson's paper in the Philosophical Transactions, 1796, relative to certain ancient arms and utensils found in the river Witham between Kirkstead and Lincoln. [14] "In the Forest of Dean and thereabouts the iron is made at this day of cinders, being the rough and offal thrown by in the Roman time; they then having only foot-blasts to melt the ironstone; but now, by the force of a great wheel that drives a pair of Bellows twenty feet long, all that iron is extracted out of the cinders which could not be forced from it by the Roman foot-blast. And in the Forest of Dean and thereabouts, and as high as Worcester, there ave great and infinite quantities of these cinders; some in vast mounts above ground, some under ground, which will supply the iron works some hundreds of years; and these cinders ave they which make the prime and best iron, and with much less charcoal than doth the ironstone."--A.

[16] This famous sword was afterwards sent by Richard I. as a present to Tancred; and the value attached to the weapon may be estimated by the fact that the Crusader sent the English monarch, in return for it, "four great ships and fifteen galleys."
