These metals, termed the noble metals, do not oxidize, but they fuse.
Like all distant unknown regions, Novaya Zemlya was of old renowned for its richness in the noble metals.
Metals of the first class are often spoken of as base, and gold and silver as noble metals.
It is a pity that this family of noble metals is so restricted, for they are unsurpassed in tenacity and incorruptibility.
In short, we use the noble metals never because of, but now and then in spite of, their costliness.
