5Laymen scarcely realize the vast strides of twentieth-century science. Transmutation of metals and other alchemical dreams are seeing fulfillment every day in centers of scientific research over the world. The eminent French chemist, M. Georges Claude, performed "miracles" at Fontainebleau in 1928 before a scientific assemblage through his chemical knowledge of oxygen transformations. His "magician's wand" was simple oxygen, bubbling in a tube on a table. The scientist "turned a handful of sand into precious stones, iron into a state resembling melted chocolate and, after depriving flowers of their tints, turned them into the consistency of glass.

"M. Claude explained how the sea could be turned by oxygen transformations into many millions of pounds of horsepower; how water which boils is not necessarily burning; how little mounds of sand, by a single whiff of the oxygen blowpipe, could be changed into sapphires, rubies, and topazes; and he predicted the time when it will be possible for men to walk on the bottom of the ocean minus the diver's equipment. Finally the scientist amazed his onlookers by turning their faces black by taking the red out of the sun's rays."

This noted French scientist has produced liquid air by an expansion method in which he has been able to separate the various gases of the air, and has discovered various means of mechanical utilization of differences of temperature in sea water.
