This structure can be rendered visible by superficial etching with dilute acid; and as the minuter crystals dissolve more quickly than the larger ones, the surface assumes a frosted appearance (moiree metallique).
This is removed by solution in hot dilute sulphuric acid and a layer of pure frosted silver is left on the surface, which appears dead white in colour, and has lost its metallic lustre.
A small frosted window allowed light to enter the room that was obviously a storage space for heirlooms.
Second: To the native Indian of Peru, the continual sight of the snowhowdahed Andes conveys naught of dread, except, perhaps, in the mere fancying of the eternal frosted desolateness reigning at such vast altitudes, and the natural conceit of what a fearfulness it would be to lose oneself in such inhuman solitudes.
The general colour is deep liver-brown, silvered or frosted with the hoary tips of the longer stiff hairs.
