LIQUID AIR MARVELS.

BEEFSTEAK, DIPPED IN IT, SMASHES IF DKOPPED. Paris, Feb. 10. M. D'Arsonval gave a successful demonstration to-day at the Museum of Natural History of the qualities of liquefied air. By enormous pressures he reached a temperature of minus 180 Centigrade. 1 The liquefied air was contained in a double-sided silver-covered bottle, and did not evaporate. Experiments with indiarubber bottles showed that they became as hard and brittle as glass. The rubbar could be pulverised, but became el: ;tic again when the air was evaporated. M. D'Avsonval showed a beef steak dipped in liquefied nir, and then let it fall on the floor, when it sounded like a stone, and broke in pieces. It was eventually reduce d to a pink powder easy to masticats and assimilate, likely to be of inipiji iant seivice in hospitals. Ice dipped in liquefied air cut glass like a diamond, mercury bscame hard as antimony. Metals, esp; jially steel, } had their qualitii ; increased tenfold by " the application of liquefied air. Conducting wire; could be reduced to a hair's breadth in thickness and remain as strong as enoimous cables.
