In these haunting reflections, Primo Levi, a chemist by training, takes the elements of the periodic table as his inspiration. He ranges from young love to political savagery; from the inert gas argon - and 'inert' relatives like the uncle who stayed in bed for twenty-two years - to life-giving car bon.
