.'■ •———^'■Mf?'^--^ DisoovERY OFA New Metal,

The Cun andArmorIContest.

The name o£ "iTorwegium" has been given to the interesting new metal discovered by Dabll some time ago, while Le was examining a specimen of nickel ore from Kragero, in Norway. This addition to tlie now rapidly growing list of elements is a malleable metal of white color, with a tinge of brown, and presents, when pure, a metallic lustre, but on exposure to the atmostp-here becomes coated with a thin tilm of oxide; its hardness is about that of copper, its specific gravity is nearly 9| and it melts at 350 degrees centrifugal. From its physical ^properties and chemical reaction, it appears so to differ from every other known rcetal as to give it a distinct iuclividuality.

From the Pall j\Iall Gazette: The lat-eat victory in tbelongdrawn match between the gun and the armor plate has been scored in favor of armor. At Spezzia a German chilled steel armor plate, five feet nine inches in thickness, weighing 100 tons, was fixed tgainst the face of the cliff and battered with chilled shot from the 100-ton gun.' A thunderbolt weighing almost exactly a ton was hurled against the face of the plate by the explosion of 7| owt. of powder without producing more than a alight indentation and some trilling cracks. Three shots failed to make any serious inipreasion on the plate, which has thus come off victor in the struggle. .;It would ae^m that no shot yet invented will- go through six feet of chilled steel.

An extensive industry has arisen in France to supply an arttfical substitute for natural ivory in view of the growing insufficiency of the latter to meet the demands of art and- industry. The majority p£ the products formerly employed''wore obtained by injecting whitewood with chloride of lime uuder sti-ong pressure. At the Amsterdam Exhibition, however, almost all the jiroducts had been prepared with the bones of sheep and waste', pieces io£ deer and jiid skins. The bones are for this purpose macerated and bleached for two weeks in chloride of lime, then heated by steam along with the skin, so as to form a fluid maRS, to which are added a few hundredths of alumj the mass is then filtered, dried in' the air, and allowed to harden in a bath of alum, the result being white tough plates, which are more* easily worked than natural ivory.

A saw -without teeth that will cut a steel rail in two minutes is in operation at the Central Hudson shops in Greenbush, N. Y. The saw is run by a ninety-horse power engine, more pow-' er than is requir^id to run all the other machinery in the shops, and is 28 inoh-es in diameter and three-eighths of an inch thick at the edge. The disk is made of Eessemer steel, and runs at a very high rate of speed. While in op-•erationi'ai/iband of lire encircles the saw, and the many .sparks Hying from the revolvihg disk resemble a display of pyrotechnics.
