...rich in hydrogen, lightest of gases and hence the most likely to escape from a planet's gravitational pull. The big planets are massive enough still to retain most of their original hydrogen, hence the ammonia and methane. The young earth locked up some useful hydrogen in water vapor and fortunately lost most of the rest...
...researchers have chilled certain salts to the astonishing temperature of .003°K. The method makes use of the principle that magnetization heats matter, demagnetization chills it. After preliminary cooling with liquid helium, the salt is magnetized, the heat thus generated drawn off into a jacket filled with helium vapor; then demagnetization pushes the substance down one notch further into the cold. But the limits of this method, as applied to the magnet ism of molecules, have been nearly reached...

...British chemist named Greville Williams broke down natural rubber by distillation, obtained a hydrocarbon compound called isoprene. In 1882 William Tilden, also of Britain, made isoprene by .racking turpentine vapor in a red-hot tube...
...Maryland's Aberdeen Proving Ground to a wooden stand overlooking a large, wet field. Soldiers stood on guard. In the middle of the field, some 2,500 feet away, stood a gibbety-looking pole, with a baglike object suspended from it. From the pendent object oozed a steamy vapor...
