...anti-Christ will not be so called, otherwise he would have no followers. He will wear no red tights, nor vomit sulphur, nor carry a spear nor wave an arrowed tail as the Mephistopheles in Faust.

Radioactive Tracer. The most spectacular test used radioactivity. A little of the unknown synthetic which the chemists hoped was penicillin was made up with radioactive sulphur built into its molecule. Mixed with natural penicillin, it was put through recrystallizations and chemical transformations...
...molecules containing radioactive sulphur could be traced with Geiger counters. If they had wandered off by themselves, they would have proved that they are different chemically from natural penicillin. But they followed it faithfully through all the processes, proving that the composition was identical...
Mustard gas was a World War I terror. For World War II, chemists developed (but never used) a variation called "nitrogen mustard" (substituting nitrogen for sulphur). In studying defenses against the new product, they noticed that nitrogen mustard had a special affinity for cells that grow rapidly. Why not try it against cancer cells...
