There was a master gas tap outside the junior physics lab. I don't remember
it being used. In those days (1945-52) we handled mercury with our bare
hands. When I was around 16, I was shown the sample of radium, wrapped in
lead foil, that was kept in the masters' room. As the labs dated back to
before 1900 the sample was doubtless bought long before there were any
government controls. I don't think I heard of "etnas" until after I came to
