Gold In Sea-Water.—In a series of researches on the composition of sea-water, a chemist named Sonstadt has been able to make out the presence of gold as one of its constituents. It appears to be completely dissolved, and is held in solution by the action of iodate of calcium, which, as shown by the same chemist, sea-water also contains. He demonstrates the presence of gold by three separate and entirely different methods, and estimates the proportion to be less than one grain per ton of water.
