METAL IN SEA-WATER. 
The French savans, MM. Malaguti, Derocher, and Sarzeaud, announce that they have detected in the waters of the ocean the presence of copper, lead, and silver. The water examined appears to have been taken some leagues off the coast of St. Malo, and the fucoidal plants of that district are also found to contain silver. The F. serratus and the F. ceramoides yielded ashes containing 1-100,000th, while the water of the sea contained but little more than 1-100,000,000th. They state also that they find silver in sea-salt, in ordinary muriatic acid, and in the soda of commerce; and that they have examined the rock-salt of Lorraine, in which also they discover this metal. Beyond this, pursuing their researches on terrestrial plants, they have obtained such indications as leave no doubt of the existence of silver in vegetable tissues. Lead is said to be always found in the ashes of marine plants, usually about an 18-100,000th part, and invariably a trace of copper. Should these results be confirmed by further examination, we shall have advanced considerably toward a knowledge of the phenomena of the formation of mineral veins.—Athenæum.
