[AS.] A soft, white, shining metal which takes on a bright polish. It is found in combination as sulphurets and oxides, and with other metals. It is widely diffused. Of mineral ores associated only 1 in 17 is free from silver, and traces of it have been found in sea-water and in organic sub-stances. Gold never occurs in nature apart from silver, and is also found with lead ; yet there is a natural distinction between the veins of the several metals. The main sources of the world's supply, after the discovery of America, were Mexico and South America; but the United States on the Pacific slope now yields silver in excess of any other country.
