The metal of the dishes, bowls, and rings, has been carefully analysed, and has been found to contain one part of tin to ten of copper, being exactly the relative proportions of the best ancient and modern bronze. The bells, however, have fourteen per cent. of tin, showing that the Assyrians were well aware of the effect produced by changing the proportions of the metals. These two facts show the advance made by them in the metallurgic art. The effect of age and decay has been to cover the surface of all these bronze objects with a coating of beautiful crystals of malachite, beneath which the component substances have been converted into suboxide of copper and peroxide of tin, leaving in many instances no traces whatever of the metals. It would appear that the Assyrians were unable to give elegant forms or a pleasing appearance to objects in iron alone, and that consequently they frequently overlaid that metal with bronze, either entirely, or partially, by way of ornament. The feet of the ring tripods previously described, furnish highly interesting specimens of this process, and prove the progress made by the Assyrians in it. The iron inclosed within the copper has not been exposed to the same decay as that detached from it, and will still take a polish. The tin was probably obtained from Phoenicia; and consequently that used in the bronzes of the British Museum may actually have been exported, nearly three thousand years ago, from the British Isles! We find the Assyrians and Babylonians making an extensive use of this metal, which was probably one of the chief articles of trade supplied by the cities of the Syrian coast, whose seamen sought for it on the distant shores of the Atlantic.
