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._ [From Bentley's Miscellany.] DR. JOHNSON: HIS RELIGIOUS LIFE, AND HIS DEATH. The title is a captivating one, and will allure many, but it very feebly expresses the contents of the volume, which brings under our observation the religious opinions of scores upon scores of other men, and is enriched with numerous anecdotes of the contemporaries of the great lexicographer. The book, indeed, may be considered as a condensation of all that was known and recorded of Dr. Johnson's practice and experience of religion from his youth to his death; of its powerful influence over him through many years of his life--of the nature of his faith, and of its fruits in his works; but there is added to this so much that is excellent of other people--the life of the soul is seen in so many other characters--so many subjects are introduced that are more or less intimately connected with that to which the title refers, and all are so admirably blended together, and interwoven with the excellent remarks of the author, as to justify us in saying of the book, that it is one of the most edifying and really useful we have for years past met with.
