A saying has obtained belief that the ocean may contain a little of everything soluble in water ; and it is curious to find from the experiments of foreign chemists that sea-water holds a determinable quantity of Silver in solution.
Various seaweeds (such as the Fucus serralus, and the Fucus ceramoides) contain an appreciable fractional amount of Silver. Some of this metal may likewise be discovered in the ashes of certain land plants. Silver is commonly found amalgamated with lead in its ore. Common salt (which is chemically chloride of sodium) when made to act upon metallic Silver forms Chloride of silver, a chemical salt highly sensitive to daylight, and thus used largely by photographers.
