PREVENTION OF RUST.

Captain Eoss, of the Artillery, has taken out a patent for a composition which, applied to the clean surface of iron, or other metals, chemically combines ■with it to form, in the case of iron, a coating of iron itself, but changed in character, and said not to rust or oxydise, even if steeped in water for a week. This discovery has been officially submitted by the inventor to his Excellency the Com-mander-in-Chief ; and the Deputy- AdjutantGeneral of Koyal Artillery himself experimented on some delicate steel articles, which had been treated by the composition, by putting them in the rain and keeping them out on the wet grass all night, which ordeal they sustained without a speck of rust. The composition is so delicate that it can be applied even to the finest needles and small clockwork wheels. We are informed that watch-springs are not affected by it, and will never rust after its application ; nor does it alter, but, if anything, improve, the temper of knife or sword-blades. It turns the surfaoe of steel implements to a whiti»h-grey colour, and is capable, perhaps, of receiving almost as high a polish as steel itself.
