LIQUID AIR FEATS.
M. d'Arsonval recently gave a demonstration of the properties of liquefied air. By enormous pressures he reached a temperature of — 180 Centigrade, The liquefied air was contained in. a double-sided silvercovered bottle, and evaporated but slowly. Experiments with indiarubber bottles showed that they became as hard and brittle as glass. The rubber could be pulverised, but became elastic again when tlie air was evaporated. M. d'Arsonval showed a beef steak dipped in liquefied air, and then let it fall on the floor, when it sounded like a stone and broke to pieces. It was eventually reduced to a pink powder, easy to masticate and assimilate, and likely to be of important service in hospitals. Ice dipped in liquefied air cut glass like a diamond, mercury became as hard as antimony. Metals, especially steel, had many of their qualities increased ten-fold by the application of liquefied air.
