Wow and I thought I would never use that particular Metallurgy class 
     again!
     
     The word plumbum is Latin for lead and is why the Periodic Table
uses 
     Pb as the symbol for lead.The Romans used lead as aqueduct piping
and 
     as decorative paint on plates - needless to say that the average
Roman 
     accumulated an unhealthy level of lead in his/her system if they
lived 
     long enough.
     
     The word argentum is Latin for silver and is why the Periodic Table 
     uses Ag as the symbol for silver. The Greek armies used to fall
sick 
     due to periodic stomach illnesses and the soldiers were sick more 
     often than the officers - the soldiers used tin cups and the
officers 
     used silver cups. What's the big deal - silver is a natural biocide 
     and killed the little creatures that were in whatever lake the
Greek 
     army was drinking out at the time!
