Results which are smaller with sulphurare followed by the — sign, those which are larger with sulphur arefollowed by the + sign. We made a similar series with white pig-iron in a crucible usingthe same iron sulphide. The white iron contained silicon carbon, and the additions diluted the silicon and carbon as sul-phur increased.
