 Combining the metallic and nonmetallic portions and recalculating, 

 after making the very unsafe assumptions that the material called 

 troilite is all the monosulphide, and that the schreibersite conforms 

 to the formula (FeNi)3P, the following figures are obtained, repre- 

 senting the composition of the stone in mass or bulk :
